Pudge
* Low armor and lack of escape makes Pudge vulnerable to Ursa, specially when he gets his Blink Dagger.
* If Pudge lands a 
Meat Hook on Ursa, Ursa can simply face Pudge head on provided he can burst him down before any follow up disables.
* Enrage's Aghanim's Scepter upgrade allows Ursa to dispel Pudge's 
Dismember.
Timbersaw
* Timbersaw's physical survivability revolves around 
Reactive Armor, which is largely ignored by Fury Swipes due to the extreme amounts of damage it does in a very few number of attacks.
* Timbersaw's burst damage will not do much against Enrage, although he could easily use 
Timber Chain to escape, wasting the duration of it.
Pudge
* 
Infernal Blade deals high damage to Pudge due to his scaling health and strength gain from 
Flesh Heap.
* Using 
Doom with timing against Pudge who had just activated 
Rot would usually kill him.
Additional:
* Doom disables the toggling of Rot and, if cast at the right time, may leave Pudge with a potentially lethal health drain.
* Doom's naturally high health, strength gain and damage output makes him a poor target for Pudge.
* The damage of Doom's Infernal Blade scales with the target's maximum health, which is particularly effective against Pudge due to his naturally high health and further health granted by stacks of Flesh Heap.
Timbersaw
* Infernal Blade deals scaling damage and is useful against high HP targets such as Timbersaw.
* Timbersaw is extremely reliant on his abilities to be effective during a team fight - both for mobility, damage and crowd control. Timbersaw offers very little, impactful right-click damage, and thus Doom is particularly crippling against him.
* Additionally, when Doom chooses the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent, Doom disables Reactive Armor, which effectively removes the durability which Timbersaw is commonly known for.
Additional:
* Doom shuts down Timbersaw completely, negating his mobility and preventing him from doing any damage. It also breaks Reactive Armor's passive bonuses from 
Aghanim's Scepter.
* Infernal Blade can stun Timbersaw several times in a fight, potentially interrupting Timber Chain. Also it's useful since Timbersaw has high HP due to the damage scales based on max HP.
Pudge
* If Meat Hook is used before 
Blink, Anti-Mage may be able to escape Pudge's grasp by blinking to safety.
* 
Counterspell grants Anti-Mage a large degree of magic resistance, a damage type Pudge is highly reliant on to secure kills. This makes Anti-Mage a bad target for Pudge. The active can also block Dismember if timed correctly.
* 
Mana Break can quickly drain Pudge's low supply of mana, which may render Meat Hook and Dismember unusable.
Timbersaw
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, 
Slark, 
Shadow Fiend, 
Clinkz, 
Bristleback 
Nyx Assassin, 
Magnus
Pudge
* No matter how high Pudge builds up strength with his Flesh Heap, all it needs is for him to fall below a certain percentage of health for him to fall to Reaper's Scythe. Considering his constant self-damage with Rot, being around Heartstopper Aura will prove risky for an overconfident Pudge.
Additional:
* 
Heartstopper Aura is effective against high health heroes, and Pudge is no exception. Coupled with his self-damage from Rot, being around Heartstopper Aura could prove risky for Pudge.
* Regardless of how much health Pudge gains through Flesh Heap, 
Reaper's Scythe will often kill Pudge should his health fall below 40%, making Necrophos an ideal counter versus Pudge.
Timbersaw
* Heroes that have escape abilities (such as 
Queen of Pain, 
Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like 
Rod of Atos or 
Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
Additional:
* Heartstopper Aura effectively negates Timbersaw's large HP pool as well as HP regen.
* 
Death Pulse together with health and mana regeneration from killed creeps helps Necrophos and his teammates survive Timbersaw's burst damage.
* As a tanky hero that stays in the middle of teamfights, Timbersaw is an easy target for Reaper's Scythe.
Pudge
* 
Shukuchi grants Weaver invisibility and a high degree of mobility for a short time, which can make him a difficult target to hook.
* 
The Swarm beetles are difficult for Pudge to remove, due to his low base attack time and poor agility. Additionally, it can be used to can scout out Pudge's location.
* Should an ally get snagged by Meat Hook, Weaver can use Aghanim's Scepter upgraded 
Time Lapse on them to send them back to where they were before hooked, even if Pudge has already started to Dismember them.
Additional:
* While Weaver is in Shukuchi, Rot doesn't slow him and Meat Hook is easy to avoid.
* Even when hooked, Weaver can use Time Lapse, negating both the damage and displacement.
* Pudge has low armor and low attack speed, making him susceptible to The Swarm and physical attacks.
* Dismember is easy to block with Linken's Sphere and it's the only way to break Weaver's Linken Sphere.
* However, the long duration stun of Dismember can be dangerous for Weaver.
Timbersaw
* In general, Timbersaw struggles against highly mobile heroes that can avoid his abilities: 
Puck, 
Weaver, 
Ember Spirit and others.
Pudge
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, 
Riki, Clinkz, Queen of Pain.
Timbersaw
* 
Searing Chains prevents usage of Timber Chain.
* Timbersaw is vulnerable to magical burst damage, which Ember Spirit provides with 
Fire Remnant and 
Flame Guard.
* Timbersaw's abilities deal pure damage, thus they cannot remove Flame Guard.
Pudge
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: 
Bane, 
Pudge, 
Witch Doctor, 
Crystal Maiden, 
Enigma.
Timbersaw
* Timbersaw relies heavily on his abilities so Phantom's Embrace's silence makes it more difficult for him.
* Timbersaw cannot use 
Return Chakram or attack the phantom during Phantom's Embrace, forcing him to take full damage and refreshes Phantom's Embrace's cooldown.
Additional:
* Timbersaw is completely powerless against 
Phantom's Embrace if 
Chakram is out.
Pudge
* The lifesteal of 
Feast scales accordingly to the max health of its target, which is effective against Pudge due to his high health and further health granted by stacks of Flesh Heap.
* Lifestealer can activate 
Rage to be spell immune, making Rot deal no damage.
* Pudge's plentiful health makes him an ideal target for Lifestealer's 
Aghanim's Shard ability, 
Open Wounds.
Pudge
* Tether and Overcharge makes it much harder for Pudge to kill a target with Meat Hook, and Relocate can save the Io's ally while Dismember is being channeled.
Pudge
* Meat Hooking a Clockwerk can backfire for Pudge, as Battery Assault and 
Blade Mail will hurt Pudge more than he hurts Clockwerk.
Timbersaw
* Timbersaw is heavily reliant on his abilities for damage and escape, allowing Silencer to effectively disable him and make him useless in both team fights and 1v1 scenarios.
Additional:
* 
Arcane Curse deals repeated stacks of damage to Timbersaw because he relies on constantly using his abilities.
* 
Glaives of Wisdom deals pure damage and when cast manually, nearby creeps will not attack silencer, making it an effective harassment tool. The intelligence steal is also especially potent against Timbersaw since he often uses up all of his mana throughout the entire game.
* Although 
Last Word takes a while to trigger, it will break Timbersaw's ability combo and can be used to silence him.
* 
Global Silence will silence Timbersaw no matter where he is on the map. This can be used to help allies get a kill on him, or prevent Timbersaw from killing someone.
Timbersaw
* 
Cold Snap can prevent Timbersaw from using both Timber Chain and Chakram due to the frequent stuns interrupting the lengthy cast animations, as well as stopping him mid-chain. This can negate Timbersaw's attempts to escape or dole out extra ability damage.
* Later in the game, Invoker's heavy magical and pure damage can be difficult to avoid, meaning Timbersaw's armor is less useful.
Pudge
* 
Kraken Shell can dispel Dismember after reaching a certain threshold of damage.
* Tidehunter's naturally high health, strength gain, and common itemization for survivability through magic resistance makes Tidehunter a poor target.
Pudge
* Legion Commander can use 
Press the Attack on an ally to dispel Dismember. The bonus health regeneration also partially counters the damage of Rot
* 
Duel can be used on Pudge whilst Rot is active, disabling toggling which may result in a lethal health drain that leaves Legion Commander with a successful duel.
Pudge
* 
Impale and 
Spiked Carapace can be used to cancel Dismember easily, and can even do so when Pudge uses it on Nyx Assassin, if timed correctly.
Pudge
* Bounty Hunter can easily keep vision on Pudge with Track, making it difficult for Pudge to hook Bounty Hunter or his team mates.
* It's difficult for Pudge to keep up with Bounty Hunter to apply Rot on him due to Shadow Walk.
* Shuriken Toss cancels out Dismember from a good range if Bounty Hunter is not the target.
Additional:
* 
Track can easily keep vision on Pudge, making it very hard for him to hook Bounty Hunter or his teammates from the fog of war.
* 
Shuriken Toss cancels Dismember from great range.
Pudge
* 
Corrosive Haze reveals Pudge's location, making it hard for him to use Meat Hook from the fog of war on Slardar's teammates or Slardar himself.
* 
Slithereen Crush interrupts Pudge while he is using Dismember.
* 
Guardian Sprint allows Slardar to avoid Meat Hook.
Additional:
* While Slardar has Guardian Sprint activated, Rot cannot slow him and Meat Hook is easier to avoid.
* Slithereen Crush allows Slardar to interrupt Dismember at close range (when Slardar is not a target).
* Corrosive Haze reveals Pudge's location, making it very difficult for him to land hooks from the fog.
Pudge
* Earth Spirit can easily disrupt Dismember because he can disable from a long distance with a Stone Remnant and Rolling Boulder. With talent he can even pull his teammates out of Dismember and also silence Pudge with Geomagnetic Grip.
Timbersaw
* Rupture and Blood Rite locks down Timbersaw, preventing him from escaping with Timber Chain. However, Timbersaw may reflect a good deal of damage with Blade Mail.
Timbersaw
* 
Hex greatly reduces Timbersaw's mobility.
* In addition, Lion can follow up with his 
Earth Spike and 
Mana Drain combo, preventing Timbersaw to escape with Timber Chain. And he can finish Timbersaw off with 
Finger of Death if the latter's HP is low enough.
Pudge
* 
Dark Pact dispels Dismember if timed correctly.
* 
Pounce allows Slark to escape Pudge's Rot once Dismember is over, and allows him to dodge hooks.
* 
Shadow Dance hides Slark and grants him a high degree of mobility, which can make him a difficult target to hook and also protects him from Pudge's Dismember (including allies with an Aghanim's Shard).
Timbersaw
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: 
Anti-Mage, 
Earth Spirit, 
Faceless Void, Magnus, 
Mirana, 
Monkey King, 
Morphling, 
Pangolier, 
Phantom Assassin, 
Phoenix, Puck, Queen of Pain, Riki, 
Sand King, 
Spirit Breaker, Timbersaw, 
Tusk.
Timbersaw
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, 
Jakiro, 
Underlord, 
Leshrac, 
Dark Seer, 
Earthshaker, Timbersaw, Crystal Maiden.
Additional:
* Timbersaw can use Chakram as a scouting tool to find Slark if he tries to Pounce into the trees.
* None of Timbersaw's abilities require a target to be cast, allowing him to hit Slark inside Shadow Dance.
* Reactive Armor can be effective protection against a Slark who attacks quickly, since the strong armor and health regen cannot be stolen by 
Essence Shift.
* Timber Chain makes Timbersaw very mobile, meaning he is among the very few heroes who can actually give chase to a fleeing Slark.
Timbersaw
* Magical burst damage is Timbersaw's weakness, and Ancient Seal not only amplifies it but also prevents him from using Timber Chain to escape for up to 6 seconds.
* He generally doesn't build early items to deal with silences.
* Reactive Armor does not trigger on magic damage or spells, meaning that even a 
Pipe of Insight won't give him the massive sustain he normally gets from attacks.
Additional:
* Skywrath Mage's long range and low cooldown magic damage spells can easily harass Timbersaw out of lane.
* 
Ancient Seal is not only a long lasting silence, (one of Timbersaw's biggest weaknesses) but it also makes him even more vulnerable to magical burst damage.
Timbersaw
* Because Timbersaw relies heavily on his spells to deal damage, Silence can easily disable him in a team fight.
* Exorcism's spirits do not count as regular attacks, and will not add stacks of Reactive Armor.
Pudge
* Meat Hook can prove annoying for Pudge if Rubick 
Spell Steals it, allowing Rubick to easily hook and save his allies being Dismembered.
Pudge
* 
Tag Team easily overwhelms Pudge, as he has low armor, which when combined with heroes with strong physical damage and Pudge's slow speed, it becomes for Pudge difficult to escape.
* 
Snowball can save a Dismembered ally and stop Pudge's Dismember.
* 
Walrus PUNCH! will removes a big chunk of Pudge's health and stun him.
* Pudge usually can't stand toe to toe against Tusk and his allies in the early game.
Timbersaw
* 
Ball Lightning makes Storm Spirit a target difficult to chase, even for a hero as mobile as Timbersaw.
* The magical damage from 
Static Remnant and 
Overload together with Storm Spirit's high mobility allows Storm Spirit to jump on Timbersaw and burst him down, even if he tries to escape.
Timbersaw
* 
Viper Strike prevents Timbersaw from gaining stacks on Reactive Armor.
Pudge
* Pudge relies on his hook to initiate his combo. As long as she's able to avoid the hook with Windrun and shackle him, Windranger can take him down easily. Pudge's low armor means that he won't be able to endure Focus Fire for long.
Timbersaw
* Heroes that withstand damage like Timbersaw, Bristleback, 
Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Pudge
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, 
Pugna, Pudge.
Pudge
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: 
Axe, Pudge, Bristleback, 
Mars.
Pudge
* Heroes that cannot move in fights such as a Dueling 
Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Additional:
* If Meat Hook is used before 
Leap, Mirana may be able to escape Pudge's grasp by leaping to safety.
* The invisibility from 
Moonlight Shadow gives a degree of mobility, which can make Mirana or her teammates difficult targets to hook.
* 
Sacred Arrow can be used to cancel Dismember from long distances.
Pudge
* Abaddon's constant heals and protection can save himself and his allies from burst-focused heroes, such as Legion Commander, Faceless Void, and Pudge.
Additional:
* Abaddon can activate 
Borrowed Time to dispel Dismember; breaking the disable and potentially allowing Abaddon to escape.
* 
Aphotic Shield can be cast on an ally to dispel the stun of Dismember, which can make kills difficult to secure, given that Dismember is Pudge's only reliable disable.
* Pudge lacks a mobility without a 
Blink Dagger, causing him to be easily chased with 
Curse of Avernus. The silence also prevents him from toggling off his Rot.
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, 
Enchantress, Queen of Pain
Pudge
* Heroes that have a weak laning stage: 
Spectre, Nyx Assassin, 
Clockwerk, Spirit Breaker, 
Omniknight, Pudge.
Additional:
* 
Void's mini-stun and silence from 
Crippling Fear will stop Pudge from using Dismember or turning off his Rot.
* Night Stalker has naturally high health, strength gain and common itemization for survivability through magic resistance, making Night Stalker a poor target for Pudge.
Pudge
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.
Pudge
* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, 
Dawnbreaker, Enigma, Pudge, Shadow Fiend, 
Shadow Shaman, 
Warlock.
Pudge
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.
Pudge
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
Pudge
* Heroes who recklessly jump on Pudge with their gap-closing abilities will be easy targets for Pudge's Meat Hook and Dismember Combo: Phantom Assassin, Faceless Void, Queen of Pain etc.
Pudge
* Generally heroes who don't rely on magical damage, such as 
Sven, Phantom Assassin, and 
Outworld Destroyer, as they can practically ignore Flesh Heap's damage block.
Timbersaw
* 
Hex greatly reduces Timbersaw's mobility.
* The stun and damage over time from 
Shackles mitigates Reactive Armor's HP and armor regen.
Pudge
* Heroes that have a channeled ability that can be interrupted by Meat Hook: Shadow Shaman, Witch Doctor, Enigma, Bane.
Timbersaw
* Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw.
* Decrepify can further increase all the magical damage done to Timbersaw, bypassing the enhanced physical resistance he can get from Reactive Armor.
Additional:
* 
Nether Ward can punish Timbersaw, as Timbersaw is a spell-caster with low cooldowns. Furthermore, Timbersaw usually appears in the midst of battle, placing himself in range of Nether Ward's Mana Flares.
* Timbersaw has no stuns or silences to stop 
Life Drain. Since all of Pugna's Spells are magical, the damage can be devastating to Timbersaw, especially when combined with 
Decrepify.
Pudge
* Heroes who build a Black King Bar (or have any sources of spell immunity) to channel abilities/items can still get interrupted by Dismember: Enigma, 
Juggernaut, Phantom Assassin, Pugna, 
Elder Titan.
Timbersaw
* 
Rolling Thunder's stuns make it harder for Timbersaw to escape with Timber Chain.
Pudge
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, 
Beastmaster, Enigma, Magnus, Pudge, 
Batrider, Bane, 
Winter Wyvern
Pudge
* Pudge has low armor and mobility, making him suspectible to her physical attacks (if Lina is the carry).
* Because Dismember is a channeled ability, it can be canceled through Light Strike Array within a distance.
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
Pudge
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like Batrider with 
Flaming Lasso, Pudge with Meat Hook and 
Vengeful Spirit with 
Nether Swap.
Timbersaw
* Heroes that can close the gap can easily chase Lina down, such as Timbersaw with Timber Chain and Anti-Mage with Blink.
Pudge
* Luna can easily cancel channeling spells with 
Lucent Beam and 0.25s Eclipse Lucent Ministun talent for 
Eclipse, she can also buy 
Abyssal Blade in case they decide to buy 
Black King Bar: Enigma's 
Black Hole, Witch Doctor's 
Death Ward, Shadow Shaman's Shackles, 
Lion's Mana Drain, Bane's 
Fiend's Grip, Pudge's Dismember, Crystal Maiden's 
Freezing Field, Pugna's Life Drain, Dawnbreaker's 
Solar Guardian, and 
Naga Siren's 
Reel In from Aghanim's Scepter.
Timbersaw
* Heroes who are melee but cannot fight back against Eclipse will really struggle with Luna: Monkey King, 
Alchemist, Timbersaw.
Pudge
* Even with Black King Bar, Pudge's Meat Hook and Dismember can still disable Luna for a fairly long time.
* Many stacks of Flesh Heap will make it difficult for Luna to burst down Pudge with Eclipse. Aghanim's Shard upgraded Dismember can also allow Pudge to save an allied hero from being killed by Eclipse.
* Bear in mind, however, that Luna can cancel Dismember if some of her allies are targets. Which may force Pudge to buy Black King Bar earlier.
Pudge
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: 
Gyrocopter's 
Rocket Barrage and Dark Seer's 
Ion Shell are just a couple examples.
Timbersaw
* Timbersaw is often too mobile and durable for Gyrocopter to bring down with his area attacks.
Pudge
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.
Timbersaw
* Because multiple Meepos tend to clump up, they present an easy target for Timbersaw's many area abilities.
* Although be careful since Timbersaw cannot use Timber Chain to escape if rooted from 
Earthbind.
Pudge
* Generally heroes who don't rely on magical damage, such as Sven, Phantom Assassin, and Outworld Destroyer, as they can practically ignore Flesh Heap's damage block.
Pudge
* Heroes with disables that ignore spell immunity will render Phantom Assassin completely useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, 
Doom, Bane, Beastmaster, Pudge, 
Medusa, Warlock.
Additional:
* If Phantom Assassin jumps on Pudge first with 
Phantom Strike, she will be a very easy target for Pudge's Meat Hook and Dismember combo.
* Even though it can deal damage based on Pudge's max health, 
Fan of Knives from Aghanim's Shard cannot disable Pudge's Flesh Heap as Flesh Heap is one of the few passive abilities that cannot be disabled by break.
* Both Meat Hook and Dismember ignore spell immunity which allows Pudge to disable Phantom Assassin even while she has Black King Bar active.
* Pudge occassionally buys armor items like Blade Mail, which in combination with many stacks from Flesh Heap can make Phantom Assassin have little effect against Pudge.
Timbersaw
* Reactive Armor helps Timbersaw sustain harassment from 
Stifling Dagger.
* Phantom Assassin has a moderate health pool and usually appears in the front line of battle, making her vulnerable to Timbersaw's pure burst damage output.
* Timbersaw can easily escape from Phantom Assassin thanks to his Timber Chain.
Additional:
* Reactive Armor helps Timbersaw sustain harassment from Stifling Dagger, as well as ganking attempts.
* Phantom Assassin is a hero with moderate HP pool, and usually appears in the front line of battle. Because 
Blur does nothing against spells, she is vulnerable to Timbersaw's skills.
* Timbersaw can easily escape from Phantom Assassin thanks to his Timber Chain.
Timbersaw
* Timbersaw's innate durability provided by Reactive Armor is very hard to deal with as Naga Siren as she mostly relies on sustained damage rather than burst damage unless if she is played as Nuker.
* Timbersaw's high pure damage and low-cooldown area-of-effect nukes which are 
Whirling Death, Timber Chain, Chakram and 
Flamethrower from Aghanim's Shard can also destroy Naga Siren's illusions very fast.
* Timbersaw is a common 
Lotus Orb wielder which allows him to reflect 
Ensnare back at Naga SIren.
Timbersaw
* Timbersaw’s reliance on nearby trees means he’ll usually be close to Hoodwink.
* More significantly, Timbersaw's tree destroying abilities cut off Hoodwink's escape options, passive and easily foil 
Acorn Shot or 
Bushwhack combos.
* While channeling 
Sharpshooter, Timbersaw can simply sit his Chakram on top of her and unleash his full combo, forcing her to cancel and disengage.
* Timber Chain can be used to dodge Sharpshooter.
Timbersaw
* Reactive Armor is very effective against Beastmaster's summons during laning stage and entire game.
* Timbersaw can quickly clear Beastmaster's summons with his nukes.
* Lotus Orb item for Timbersaw can releases roar from the target position, stunning and damaging Beastmaster and knocking away, damaging and slowing allies that stand on the way.
Pudge
* Meat Hook can be used immediately after 
Mortimer Kisses since Snapfire is forced to stay in place.
Timbersaw
* Timber Chain can kite Troll Warlord extremely effectively.
* Whirling Death and Chakram deals lots of damage to Troll Warlord.
* Reactive Armor makes Timbersaw extremely resilient to Troll's attack damage and extreme attack speed, especially during Battle Trance.
Pudge
* Sniper has a low health pool and strength gain, making him vulnerable to Pudge's magical and pure damage.
* Sniper usually likes to deal damage away from the fight, and Meat Hook is capable of bringing him to the front lines.
* 
Assassinate won't do much damage against Pudge because of his high strength gain and the strength bonuses from Flesh Heap.
* 
Shrapnel will be mostly blocked by Flesh Heap's active.
Additional:
* Pudge's Meat Hook allows him to bring Sniper in the middle of any fight, and the pure damage does well against his high armor and low health.
* Dismember can lock Sniper down, which makes him highly vulnerable and gives enough time for Pudge to kill him alone. Aghanim's Shard upgraded Dismember will also allow Pudge to save an ally from Assassinate.
Timbersaw
* Timbersaw can use his plethora of tree cutting abilities to level entire sections of the forest, making hiding in the trees more difficult for Treant Protector and his team.
* Timbersaw can easily cut down Treant Protector's 
Eyes In The Forest once his team has detection. He may even do it unknowingly due to the sheer destructive and chaotic nature of his abilities.
Additional:
* Not only are all of Timbersaw's active abilities capable of cutting down trees, but Whirling Death and Timber Chain also require it to be effective, counteracting both Treant Protector's Nature's Guise and Eyes in the Forest abilities.
Pudge
* Even with Black King Bar or 
Linken's Sphere, Pudge's Meat Hook can still cancel Crystal Maiden's Freezing Field as she is a very easy target while channeling it.
* Pudge's Rot can make Crystal Maiden's already bad movement speed even worse.
* Many stacks of Flesh Heap will make it nearly impossible for Crystal Maiden to kill Pudge.
* Pudge's Dismember can also be used to cancel Crystal Maiden's Freezing Field, and alternatively, Pudge can also use it to save allies from getting killed by Crystal Maiden and heal them when upgraded with Aghanim's Shard.
* Crystal Maiden is prone to ganks in the lane or in the off-lane without proper vision. Pudge can take advantage of Crystal Maiden's lack of mobility, and gank her often.
Additional:
* Meat Hook can cancel Freezing Field, even if Crystal Maiden has 
Glimmer Cape.
* She is also slow and fragile, making her a good target for ganking.
Timbersaw
* Timbersaw's pure damage will kill Dragon Knight surprisingly fast, especially if he gets caught in a bad position while laning.
Timbersaw
* Timbersaw Defeats Kunkka on the center line, due to the fact that he has a huge resistance to physical damage by Reactive Armor, which is why 
Tidebringer almost does not break through Timbersaw, and due to Whirling Death Timbersaw can very much break through Kunkka and force him to leave the line, or spend money on 
Tango.
Additional:
* Timbersaw easily beats Kunkka on the midlane, due to the fact that he has huge physical damage resistance from Reactive Armor, which is why Tidebringer almost does not break through Timbersaw, and due to Whirling Death and Kunkka being a strength hero, Timbersaw can very much break through Kunkka and force him to leave the lane, or spend money on Tango.
Pudge
* Pudge's Dismember stops Spectre from escaping with 
Haunt.
* He can easily tank the damage reflected by 
Dispersion due to his high strength and the healing from Dismember.
* Should Spectre try to get away through the trees or over a cliff with 
Spectral Dagger, Pudge can hook her back.
* Spectre takes a long time to become powerful, and Pudge can ruin her early game with ganks.
Pudge
* Meat Hook brings Drow Ranger to Pudge, disabling Marksmanship and dealing a huge amount of damage when combined with Rot and Dismember.
* Rot keeps Pudge close to Drow Ranger, continuously disabling Marksmanship.
Additional:
* Meat Hook can pull Drow Ranger to Pudge, disabling her 
Marksmanship.
* Following up with Dismember will prevent Drow Ranger from using 
Gust or 
Shadow Blade.
Pudge
* Even with Black King Bar, Pudge's Meat Hook and Dismember can still disable Engima while he is channeling Black Hole as Enigma is a very easy target while channeling Black Hole.
* Pudge's Aghanim's Shard upgraded Dismember and Meat Hook are great ways to save allies from Black Hole.
* Enigma is prone to ganks in the jungle or in the off-lane without proper vision. Pudge can take advantage of Enigma's lack of mobility, and gank him often.
Timbersaw
* All of Timbersaw's spells deal AoE damage, killing Lycan's summons very quickly.
* Reactive Armor will gain stacks quickly because of Lycan's summons.
Timbersaw
* Reactive Armor prevents Broodmother's spiderlings from being able to effectively harass Timbersaw in the lane.
* Timber Chain's high mobility makes Silken Bola's slow irrelevant, unless Broodmother already bought her Orchid.
* Silken Bola's miss chance doesnt affect Rizzrack that much because he does not rely on his autoattacks much.
* Lotus Orb items for Timbersaw make Silken Bola useless.
* Timbersaw's abilities can destroy any trees that Broodmother attempts to hide in and his AoE abilities can quickly clear her Spiderlings.
Additional:
* Spiderlings deal almost no damage against Reactive Armor. They also die quickly from Timbersaw's AoE abilities.
* Broodmother has no mobility ability except the movement speed buff from 
Spin Web, allowing Timbersaw to easily escape her 
Silken Bola with Timber Chain.
* Timbersaw's tree-cutting abilities make it difficult for Broodmother to hide, especially near the edges of the map.
Pudge
* Meat Hook can hit and displace Juggernaut during his 
Blade Fury.
* Dismember pierces Juggernaut's spell immunity from Blade Fury.
Timbersaw
* Timbersaw relies on dealing massive amounts of pure damage, making Cold Embrace a good setup for his nukes.
* If he has Reactive Armor stacks, Timbersaw can tank the damage from his allies if he is targeted by Winter's Curse. If he's not the target, Timbersaw's abysmal attack damage will contribute next to nothing when he is cursed to attack an ally.
* As Timbersaw commonly buys Lotus Orb, he can use it to reflect Winter's Curse back to Winter Wyvern if she uses it impulsively on him or any other hero while affected by it.
Pudge
* Rot is not very effective against Chen's creeps.
* Chen can use his creeps to cover him or his allies from any attempts of Meat Hook.
* {U:Centaur Conqueror} or {U:Mud Golem} under Chen's control can interrupt Dismember.
Pudge
* Heroes with channeling spells, for Chen has no disables on his own, hates buying disabling items and his creeps are often not fast enough to cancel them: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.
Timbersaw
* With Timber Chain, Timbersaw can slow, catch up with, or escape from Chen and his creeps.
* Chakram and Flamethrower from Aghanim's Shard can clear Chen's creeps and slow him.
* Attacks from multiple creeps will quickly build Reactive Armor stacks, making attacks of Chen and his creeps only tickle Timbersaw.
Timbersaw
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, Enigma, 
Invoker, Pugna, 
Skywrath Mage, 
Tinker, 
Zeus, 
Oracle.
Pudge
* Heroes with channeling spells because Shadow Fiend has nothing to cancel channeling outside of Requiem of Souls: Bane, Enigma, Pudge, Shadow Shaman, Dawnbreaker, Warlock, Crystal Maiden.
Pudge
* Pudge has low armor and low mobility, making him a prime target for Terrorblade's right-clicks.
* Meat Hook is a lot harder to land on the real Terrorblade if he has illusions around him.
* Because Dismember targets only one hero, Terrorblade's illusions can potentially save the real Terrorblade if he's caught in it.
Pudge
* Heroes who have channeling abilities because Terrorblade has no disables to cancel them at all besides 
Terror Wave from Aghanim's Scepter, and he does not like buying disabling items at all: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.
Timbersaw
* Timbersaw's abilities combos all deal magical and pure damage, completely ignoring Terrorblade's high base armor and clearing his illusions very quickly due to the AoE damage.
* Reactive Armor negates most of Terrorblade's damage against Timbersaw, and its high health regeneration and armor bonuses can help Timbersaw survive after Terrorblade has used 
Sunder on him.
Additional:
* Timbersaw can take down Terrorblade's illusions with his area damage burst.
* Reactive Armor plus another armor item reduce much of Terrorblade's damage.
Pudge
* Heroes that have a channeled ability that can be interrupted by Meat Hook: Shadow Shaman, Witch Doctor, Enigma, Bane.
Additional:
* Meat Hook interrupts Death Ward from a decent range, even through Black King Bar & Glimmer Cape.
* Pudge can survive the damage from Maledict because of his Flesh Heap stacks.
* However the damage-over-time from Rot is counteracted by Voodoo Restoration.
Pudge
* Heroes that can cancel Charge of Darkness: 
Ogre Magi, Earthshaker, Lion, 
Rubick, Lina, 
Luna, Jakiro, Dawnbreaker, Alchemist, Ogre Magi, Axe, Shadow Shaman, Naga Siren, Mars, Bane, Pudge, Clockwerk.
Timbersaw
* Special mention to Timbersaw as he has a way to deal with Axe in the laning stage, but still needs to be careful about Berserker's Call stun, the pure damage from Counter Helix and Culling Blade finishing him off before he can escape or heal from his passive.
Additional:
* Whirling Death reduces Axe's strength by 15%, which makes him less durable, especially from early game. It's also stackable.
* Blade Mail are not effective against attribute changes, and Timber Chain can wait out Blade Mail's duration to wear off.
* Reactive Armor makes it harder for Axe to finish off Timbersaw with 
Culling Blade.
* Chakram disarms Timbersaw, which makes Axe's 
Counter Helix useless against him.
* All Timbersaw skills deal pure damage, which bypass Axe's high armor or bonus armor from 
Berserker's Call.
Pudge
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: Gyrocopter's Rocket Barrage and Dark Seer's Ion Shell are just a couple examples.
Timbersaw
* Timbersaw: Lone Druid will have a hard time dealing with Timbersaw due to his tankiness and high Armor from Reactive Armor
Timbersaw
* All Tinker's damage is magic/pure and completely ignores Timbersaw's Reactive Armor.
* Timbersaw very rarely builds Black King Bar, making him very vulnerable if Tinker builds Scythe of Vyse.
Pudge
* Meat Hook can be used to pull Tinker to Pudge while he is hiding in the trees, and a follow up with Dismember and Rot can lead to a valuable kill, as Tinker doesn't buy many survivability items.
* Flesh Heap makes it hard for Tinker to deal serious damage.
Additional:
* Pudge can Meat Hook a Tinker hiding in the trees and follow it up with Dismember and Rot for an easy solo kill, as Tinker doesn't tend to buy survivability items.
* Many stacks of Flesh Heap combined with items that give Pudge high strength and health will make it hard for Tinker to deal serious damage to Pudge.
Timbersaw
* Timbersaw's ability to destroy trees can be a serious problem for some heroes that use them, as either a way of enhancing their spells like 
Treant Protector, or heroes that tend to hide inside of them like Tinker and Monkey King.
Timbersaw
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as Timbersaw, or those who can dispel them, such as 
Phantom Lancer, can kill Oracle unhindered.
Timbersaw
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
Timbersaw
* The burst damage from Timbersaw's abilities is more than enough to deal with Enchantress and her creeps.
* Timbersaw doesn't rely on his physical attacks, which makes Untouchable useless against him.
* Timber Chain can close the gap between them and minimize damage from Impetus.
* Bear in mind, however, that Timber Chain can also work against Timbersaw if used to escape and that Impetus can ignore Reactive Armor if Enchantress is not a primary target for Timbersaw or if he is disabled.
* Timbersaw is a common wielder of Lotus Orb, which will allow him to reflect Enchant back at Enchantress and dispel most debuffs as well.
Pudge
* Any heroes that naturally buy 
Diffusal Blade like Phantom Lancer or have a mana break talent is a big issue for Pudge because of his low mana pool.
Timbersaw
* All Timbersaw's abilities deal AoE pure damage and can easily deal with Phantom Lancer's illusions.
* Reactive Armor highly negates Phantom Lancer's physical damage, making him having a hard time killing Timbersaw.
Additional:
* Phantom Lancer's lack of burst damage and constant attacks will increase Reactive Armor to max level immediately.
* Coupled with Timber Chain, it makes an easy escape and almost impossible for Timbersaw to be killed by Phantom Lancer.
* Whirling Death and Chakram can instantly destroy large groups of illusions, negating Phantom Lancer's advantage, although Phantom Lancer usually builds Diffusal Blade. It can be a problem in late game.
Pudge
* Heroes with many summons or illusions are much harder to catch with Meat Hook: 
Nature's Prophet, Phantom Lancer, 
Chen.
Timbersaw
* All three of Timbersaw’s abilities give him an easy way out of Sprout, and can also destroy nearby trees so Nature's Prophet can’t spawn Treants.
* If Prophet tries to escape with a self Sprout/Teleport, Timbersaw can easily cut down all its trees to get to him and deal increased Whirling Death damage as well.
* Chakram heavily discourages teleports.
* Timbersaw is quite well suited to clearing massive waves of Treants almost instantly with all of his area of effect pure damage abilities, preventing Nature's Prophet from pushing.
* Treants can give Reactive Armor many charges quite quickly.
Additional:
* Timbersaw can easily cut down trees from 
Sprout, making it very difficult for Nature's Prophet to teleport away or trap enemies.
* Timbersaw's abilities quickly clear out treants.
* Reactive Armor negates most of the damage of Nature's Prophet's treants, and Timbersaw can often allow himself to be attacked in order to heal himself.
Timbersaw
* Reactive Armor's armor increase does not affects Muerta's Pierce the Veil despite Muerta often building high attack speed.
* Muerta's 
Dead Shot destroys trees preventing Timbersaw from escaping with his Timber Chain.
Pudge
* Pudge's high health and damage block from Flesh Heap make him difficult for Muerta to burst.
* Pudges high magical damage from Meat Hook and Dismember can quickly burst down Muerta, especially in 
Pierce The Veil and even through Black King Bar.
* Muerta has no escape abilities and is slow, making her an easy target for Pudge's Meat Hook and Rot.
* Pudge can prevent an ally from being attacked by 
Gunslinger if he has Aghanim's Shard.
Pudge
* Anti-Tank heroes like: 
Razor, 
Necrophos, 
Undying.
Timbersaw
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.
Additional:
* Razor deals mostly physical damage towards the later game, and Timbersaw is also very mobile, making him a difficult kill to earn.
* Timbersaw rarely resorts to attacks, thus does not suffer when his damage is stolen with 
Static Link.
Pudge
* His low armor deters him from a trade,while 
Jingu Mastery allows Monkey King to retaliate.
* Buffed 
Boundless Strike heals Monkey King and can potentially execute Pudge.
* Monkey King can scout Pudge's positioning from the trees, making it easier for him and his allies to dodge Meat Hook.
* With a better-than-average strength gain, he usually survives Pudge's combo.
Timbersaw
* Timbersaw's low cooldown and low mana cost abilities destroys the trees that Monkey King depends on.
* Timber Chain allows Timbersaw to escape Wukong's Command.
Additional:
* Timbersaw can easily cut down the tree that Monkey King is standing on, stunning him for a lengthy period.
* Timbersaw can use Timber Chain to easily escape 
Wukong's Command and 
Primal Spring's slow.
* However, when facing Monkey King mid, Timbersaw might get harassed out of the lane because of Jingu Mastery.
Pudge
* Phantasm's illusions make it difficult to land Meat Hook and Dismember.
* Chaos Bolt is a comparatively low cooldown tool to interrupt Dismember.
* Chaos Strike's lifesteal offsets Rot's damage.
Additional:
* Unlike any other illusion heroes, Chaos Knight is the worst target for Pudge to hook as it will definitely backfire him.
* 
Phantasm are significantly tankier than most illusion and deal full damage, which will quickly kill Pudge due to his low armor.
* it becomes worse if pudge is affected with 
Reality Rift, which reduces his already abysmal base armor even lower.
* Low movement speed and low mobility means Pudge will struggle to escape or outrun Chaos Knight in most cases.
Timbersaw
* Strong area damage, particularly from Whirling Death and Chakram, lets Timbersaw clear out illusions quickly.
* Whirling Death directly reduces Strength from both Chaos Knight and his Phantasm illusions, reducing both the damage output and raw health that the hero relies on.
* Reactive Armor quickly builds stacks against Phantasm illusions, making Timbersaw harder to kill.
Additional:
* Reactive Armor helps Timbersaw to endure the damage from 
Chaos Bolt and Reality Rift combo.
* Timbersaw's large amount of pure damage AoE nukes clears Chaos Knight's illusions quickly, drastically reducing his damage.
Timbersaw
* 
Time Dilation is similar to a long duration silence, making Timbersaw useless in team fights, or forcing him to adapt his build.
* 
Time Walk negates Timbersaw's burst damage.
* 
Time Lock provides magical damage and lock down, and is effective against both Reactive Armor and Timber Chain.
* In conjunction with Time Lock's magical damage, 
Chronosphere can destroy Timbersaw before he has time to react, and creates a large obstacle that obstruct's Timber Chain's mobility.
Pudge
* Meat Hook can pull an ally out of Chronosphere.
* Rot will keep damaging Void if he toggled it before Chronosphere, but you can lower your hp for Faceless Void.
* Flesh Heap will help Pudge survive through the Chronosphere with enough stacks, and follow with Dismember.
Timbersaw
* Bramble Maze prevents Timbersaw from Timber Chaining away without getting rooted.
* Cursed Crown can still catch Timbersaw if he Timber Chains away.
* Reactive Armor offers little protection against Dark Willow's high magical damage.
Pudge
* Rot and Meat Hook hits Dark Willow even when she uses Shadow Realm.
* Flesh Heap reduces Dark Willow's magic burst damage.
Timbersaw
* Zeus deals enormous amounts of magic damage, being one of the best heroes to burst down Timbersaw early in the game.
* 
Lightning Bolt's mini-stun can stop Timbersaw's from escaping a fight with Timber Chain.
Additional:
* Reactive Armor will not trigger from Zeus's spells or protect Timbersaw from their damage.
* Early game Timbersaw's strength is average and Zeus can heavily aid in bursting him down.
* Late game, if Timbersaw has built a lot of HP items, Zeus's passive Static Field will be more effective at chipping away Timbersaw's large HP pool.
* A Timbersaw who builds Pipe of Insight will be much more difficult to kill, as Zeus has no way to hold Timbersaw down, but Timbersaw will have less armor, mana, and damage than normal if he buys this item early game just to counter Zeus.
Pudge
* Zeus likes to stay far back in fights, dealing his damage uninterrupted, but once he gets hooked into the fight, he usually dies very quickly.
* Pudge's high strength from Flesh Heap makes it very hard for Zeus to burst him down.
* Zeus' low health pool makes him very vulnerable to the damage from Meat Hook, Rot and Dismember.
Additional:
* Meat Hook's high range allows Pudge's team to drag Zeus in the middle of the fight and abuse his frailty.
* Flesh Heap's health and magic resistance bonus makes Pudge exceptionally resistant to Zeus' nukes. In later stages of the game, Zeus is usually unable to seriously damage Pudge at all. Even Static Field, which deals damage based on a percentage of the enemy's health, won't be doing much.
* Even if Zeus buys a Black King Bar, Meat Hook and Dismember still disable him for a long time, usually causing Zeus' quick death.
* Zeus is vulnerable to early ganks, which Pudge excels at.
Pudge
* Bristleback is one of the hardest heroes to gank with a Meat Hook and Dismember combo, and attempts to do so sometimes backfire on Pudge.
Additional:
* Pudge is particularly susceptible to Bristleback's 
Viscous Nasal Goo and 
Quill Spray due to his naturally low armor and poor agility gain.
* Bristleback, in combination with his strength gain, high health, common itemization for magic resistance and damage reduction from 
Bristleback makes him a poor target for Pudge.
Timbersaw
* Whirling Death deals damage while also reducing {Show:A|Timbersaw|Whirling Death|value4} of Bristleback's strength, making him less tanky.
* Reactive Armor can sustain through multiple Viscous Nasal Goo and Quill Spray stacks.
* Timber Chain makes it hard for Bristleback to slow down Timbersaw even with Viscous Nasal Goo.
Timbersaw
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, 
Lycan, 
Bloodseeker, Anti-Mage, Timbersaw.
Pudge
* Axe, Bristleback, 
Centaur Warrunner, Spirit Breaker, Pudge, 
Huskar, 
Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Timbersaw
* 
Brain Sap's pure damage ignores stacks of Reactive Armor.
* 
Nightmare prevents Timbersaw from using Timber Chain, setting him up for chain stuns and burst damage.
* 
Enfeeble highly reduces regeneration granted by reactive armor.
* Fiend's Grip immobilizes Timbersaw and drains his low mana pool, preventing escape afterwards. It also pierces Black King Bar.
* Bane's multiple disables often force Timbersaw or his teammates to spend gold on a Linken's Sphere.
Pudge
* Even with Black King Bar, Pudge's Meat Hook and Dismember can still catch and disable Bane while he is channeling Fiend's Grip, breaking the channel as a result, Meat Hook can also be used to save targets affected by Bane's abilities.
* Dismember can disable Bane while channeling Fiend's Grip if Pudge is not targeted. Aghanim's Shard upgraded Dismember can also be used to save an allied hero that is targeted by Fiend's Grip.
* Pudge's high health and health regeneration allows him to survive through most of Bane's abilities.
Pudge
* Anti-Tank heroes like: Razor, Necrophos, Undying.
Timbersaw
* Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, Lycan and Undying.
Timbersaw
* Templar Assassin 
Meld`s ability will break Timbersaw's armor, which makes it very easy to break through and not feel his Reactive Armor, which will allow the team to kill Timbersaw quickly, or drive him out of the fight.
* Templar Assassin's 
Refraction ability gives her the ability to avoid damage from Whirling Death, which will give her the ability to deal Timbersaw more damage than he will deal.
Additional:
* Templar Assassin Meld`s ability will break Timbersaw's armor, which makes it very easy to break through and not feel his Reactive Armor, which will allow the team to kill Timbersaw quickly, or drive him out of the fight.
* Templar Assassin's Refraction ability gives her the ability to avoid damage from Whirling Death, which will give her the ability to deal Timbersaw more damage than he will deal. However, he may easily burn through Refraction with Chakram.
Pudge
* His Rot can force Templar Assassin out of her Meld and destroy all of her Refraction charges quickly, and her small health pool and meager defense make her very vulnerable to his Meat Hook without Refraction.
Pudge
* Pudge has a very hard time killing Familiars due to his melee range and low attack speed.
* Stone Form can quickly interrupt Dismember.
Timbersaw
* Reactive Armor will quickly stack up from Familiar attacks, making Timbersaw hard to kill.
* Visage's low mobility makes it easy for Timbersaw to line up his abilities.
Pudge
* Slow heroes that have a hard time escaping the Echo Stomp radius: Crystal Maiden, Pudge, 
Techies.
Pudge
* Heroes who build a Black King Bar (or have any sources of spell immunity) to channel abilities/items can still get interrupted by Dismember: Enigma, Juggernaut, Phantom Assassin, Pugna, Elder Titan.
Pudge
*
Sanity's Eclipse deals more damage the less max mana the heroes hit by it have, making Pudge an ideal target.
Astral Imprisonment.
* Outworld Destroyer can save allies or himself caught by Dismember or Meat Hook with
Timbersaw
* Arcane Orb's pure damage ignores Timbersaw's
Reactive Armor.
Timber Chain, preventing him from escaping.
Arcane Orb deals constant pure damage, which bypasses Timbersaw's Reactive Armor.
Sanity's Eclipse can hit targets inside 
Astral Imprisonment, which helps Outworld Destroyer finish off Timbersaw before he escapes with Timber Chain. It can also drain his mana, limiting his ability to escape should he survive.
* Astral Imprisonment, if timed correctly, can interrupt
Additional:
