* Tidehunter's
Kraken Shell dispels Corrosive Haze and Bash of the Deep's stun if enough damage is taken.
Anchor Smash and Kraken Shell's damage block also reduces Slardar's damage.
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter,
Bristleback,
Slardar.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky:
Riki,
Naga Siren,
Terrorblade,
Juggernaut,
Spectre,
Slark.
* Terrorblade starts out with and gains a lot of armor from his agility growth. His illusions also make it difficult for Slardar to focus down the real Terrorblade.
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky:
Riki,
Naga Siren,
Terrorblade,
Juggernaut,
Spectre,
Slark.
* Abaddon can cast Aphotic Shield on any of his allies to immediately dispel Corrosive Haze and/or the stun and the slow components of Slithereen Crush.
* All of Slardar's debuffs are also removed if Abaddon's Borrowed Time triggers.
* Fortune's End applies a basic dispel which can be used to dispel Corrosive Haze, or even Slardar's own Guardian Sprint.
* False Promise is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
* Fate's Edict can also be cast on Slardar to prevent him from proccing his Bash of the Deep.
* Webbed areas can be used to hit and run, covering distance hastily weakening her on the way and initiating ganks.
* Even though Medusa can hunt down Spiderlings easily when given enough range, Silken Bola will cause her attacks to miss and get her swarmed in no time.
* Medusa usually does not build a Black King Bar to benefit from Mana Shield fully while Broodmother can fit a
Diffusal Blade to burn away all of Medusa's mana.
Additional:
* Spin Web will allow Broodmother to pick her own fights and sometimes slip away to ambush Medusa.
* Though Medusa's Split Shot and Mystic Snake can help Medusa deal with Broodmother's spiderlings, Broodmother will create too much of them for her to handle, allowing her to outnumber Medusa's targets from Split Shot and shield her team in process.
* Silencer burns easily through her effective HP from Mana Shield, by taking away her intelligence.
* Arcane Curse punishes her repeatedly casting
Mystic Snake to keep her mana pool high. He can force her to use
Manta Style before he has cast
Global Silence and
Medusa usually does not want to build
Black King Bar.
* He can use either his own or his double's Flux to bypass the spellblock from Linken's Sphere, using the leftover Flux +
Spark Wraith to slow Medusa's already low move speed to a crawl.
* Arc Warden has a farming advantage with double Hand of Midas, and can generally bully Medusa with other items that benefit from duplication.
* Fiend's Grip provides mana drain, which can heavily damage Mana Shield and prevent Medusa from using
Stone Gaze.
* Even if she does use Stone Gaze, Nightmare can buy enough time to protect allies and reset the fight.
Additional:
* Fiend's Grip leaves Medusa defenseless, since not only does it deal damage, it also drains mana.
* Fire Spirits greatly reduces Slardar's already low starting attack speed (which Bash of the Deep relies on), making the laning phase very hard for him and discouraging Slardar from aggressively threatening lane kills.
* Supernova, ignoring Phoenix's lack of armor and Slardar's high damage single hits, is extremely hard for Slardar to take down on his own, especially after being hit by Fire Spirits.
* Icarus Dive is one of the longest distance escape spells in the game, and can help a good Phoenix escape from Slardar before he gets a
Blink Dagger. However, the high cooldown means Phoenix is vulnerable to backstabs from any roamers after said spell is used.
* Slardar can interrupt an Icarus Dive from completing the flight with both of his stuns, however, likely leading to death if Supernova is on cooldown.
* A lot of the items a Phoenix builds throughout the game naturally counter Slardar. Shiva's Guard,
Heaven's Halberd and
Eul's Scepter of Divinity all stall Slardar's normal attacks in some way, while
Spirit Vessel's percentage-based damage is good against his innate durability.
* With Static Link, Razor can effectively make Medusa useless in teamfights by reducing her main damage output. It can, however, be blocked by a
Linken's Sphere.
* Plasma Field allows Razor to get on top of Medusa, slowing her already slow movement speed to a mere crawl.
* Eye of the Storm capitilizes on Medusa's low armor and causes her to be very vulnerable, even through
Mana Shield.
* Medusa lacks mobility or escape mechanisms.
Earth Spike and
Hex can neutralize her strong damage potential and allow for
Lion's team to focus her down.
* Mana Drain is a perfect ability to weaken Medusa's durability as it can quickly drain her
Mana Shield, making her far less tanky.
Mana Drain can also be used to restore mana of Lion's allies, which can nullify the mana steal from
Mystic Snake.
* Mana Drain, along with
Hex, destroy illusions instantly, which may be extremely helpfull and efficient against core builders of
Manta Style, like
Medusa herself.
* Heroes with extremely slow movement speed will cripple against Solar Bind: Medusa,
Viper
Additional:
* Will-O-Wisp will keep Medusa busy after she got hit by
Blinding Light.
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as Medusa,
Drow Ranger...
* Slardar has high priority on building moblity items such as Blink Dagger rather than tank items. Zeus can easily deal large amount of damage to him if not caught out of position first.
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina,
Zeus.
* E.M.P. allows Invoker to burn Medusa's mana to weaken Mana Shield.
* Medusa's lack of mobility makes her easy to kite with Invoker's spells.
Additional:
* E.M.P. is a large mana burn nuke which can hit Medusa's Mana shield with enough damage to lose even more mana.
* Deafening Blast disarms Medusa's ability to deal pseudo-AOE damage during teamfights.
* Cold Snap allows the opposing team to repeatedly stun Medusa in short succession, preventing her from successfully casting her ultimate due to its long cast time.
* Bounty Hunter and
Slardar both have ultimates (
Corrosive Haze and
Track) that reveal Invoker through Ghost Walk.
* Medusa is especially vulnerable to Essence Shift, as both strength and intelligence contribute to her effective HP, while agility contributes to her damage.
* Dark Pact when timed right can be used to dispel Stone Gaze right after it petrifies Slark, allowing him to keep attacking Medusa throughout the duration.
Additional:
* Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regenerating before coming back to finish her off.
* Essence Shift particularly removes 1 intelligence point per hit, thus lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.
* Slardar's level 25 talent makes
Corrosive Haze undispellable, thus providing his allies vision of Slark.
* Bulwark can make each of Medusa's attacks target him instead, reducing Medusa's contribution on team fights.
* Spear of Mars stuns Medusa and also pushes her away from teamfights, taking advantage of Medusa's low mobility.
* Arena Of Blood blocks Medusa's attacks from outside the arena.
* Medusa's
Stone Gaze forces Mars to choose between getting petrified, or turning his vulnerable back on Medusa.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky:
Riki,
Naga Siren,
Terrorblade,
Juggernaut,
Spectre,
Slark.
* Medusa's Split Shot and
Mystic Snake combined with
Mjollnir, a common item for Medusa, will whittle down all of Naga Siren's illusions, including Naga Siren herself.
* Medusa's Stone Gaze can disable Naga Siren even for the duration of
Song of the Siren and even if Naga Siren is spell immune, discouraging Naga Siren from even trying to use
Song of the Siren to save herself or counter-initiate against Medusa.
Additional:
* Medusa's Split Shot and
Mystic Snake combined with
Mjollnir, a common item for Medusa, will whittle down all of Naga Siren's illusions, including Naga Siren herself.
* Medusa's Stone Gaze can disable Naga Siren even for the duration of
Song of the Siren and even if Naga Siren is spell immune, discouraging Naga Siren from even trying to use
Song of the Siren to save herself or counter-initiate against Medusa.
* With armor items like Solar Crest or
Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the
Duel, If not dueled himself, he can drop
Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.
* Mana Shield makes Medusa very hard to take down in Duels.
* Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback,
Clinkz,
Luna,
Shadow Fiend,
Slardar,
Terrorblade
* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces Rage, wasting its cooldown and making Lifestealer unable to fight.
* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and
Dazzle.
* Visage's familiars are easy targets to Split Shot.
* Mana Shield will resist Soul Assumption instances without effort.
* While Slardar has Guardian's Sprint activated, Powershot cannot slow him and is easier to avoid.
* Slithereen Crush and Bash of the Deep help Slardar put Windranger in place, even when she uses Windrun to escape.
* Corrosive Haze from Slardar is very effective against Windranger's already low armor. This becomes even worse if she has Aghanim's Scepter-upgraded
Windrun, because it also reveals her position and allowing his allies to use their abilities on Windranger.
* Note that the invisibility provided by Aghanim's Scepter-upgraded
Windrun is not broken upon attacking, casting abilities or using items, so it's vital to cast Corrosive Haze beforehand.
* Enchantress often has a small army of neutral creeps, allowing Medusa to hit her with a later bounce of her Mystic Snake.
* Stone Gaze allows Medusa to easily kite and kill Sven.
* Mana Shield negates much of Sven's burst damage.
Additional:
* Mana Shield makes it very hard for Sven to burst her within Storm Hammer's stun duration.
* Stone Gaze makes it very difficult for Sven to fight Medusa at any stage of the game.
* Mystic Snake can slow Sven down enough for allies to capitalize on his commitment in a fight.
* Shadow Fiend, a normal Shadow Blade builder often relies on its invisibility to escape fights. Corrosive Haze reveals Shadow Fiend and also weakens his already low armor.
* Medusa's Split Shot can easily kill Chen's creeps.
* Mystic Snake can quickly kill Chen's creeps and deal intense damage for every killed creep while also draining their mana with each bounce.
Aghanim's Scepter upgraded
Mystic Snake can also disable both, Chen and his creeps upon impact.
* Mana Shield will make it impossible for Chen to burst down Medusa.
* Stone Gaze can disable Chen from using
Hand of God to save himself or his allies.
* Split Shot will keep attacking Pangolier even when he is rolling around.
* Stone Gaze stuns Pangolier during Rolling Thunder, or forces him to roll away.
* Doom does not disable Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.
* 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.
* Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.
* Weaver relies on Shukuchi to escape and kite enemy heroes. Slardar's Corrosive Haze lowers armor and reveals Weaver, who is already a very frail target.
* Weaver usually builds Linken's Sphere, Corrosive Haze can be used to pop the spell block, additionally the level 25 undispellable talent will prevent Weaver from removing Corrosive Haze with
Time Lapse, allowing allied heroes to use their abilities on Weaver.
Additional:
* Corrosive Haze lowers armor and reveals Weaver during Shukuchi, who is already a frail target. In addition, Weaver usually builds
Linken's Sphere, and
Corrosive Haze can be used to "pop" the spell block. His level 25 talent can also make Corrosive Haze undispellable by Time Lapse, which puts Weaver in an even worse situation.
* Guardian Sprint can dodge Weaver's bugs with the movement speed bonus.
* Her Mana Shield is too tough for Lycan to break.
* Mystic Snake can hit for a massive damage once it spread between his summons.
Additional:
* Can be easily petrified despite his speed.
* Summoned wolves will be targeted by Split Shot or Mystic Snake
* Corrosive Haze followed by
Slithereen Crush takes advantage of Alchemist's main weakness, being physical damage before he has the change to improve his surviability with items.
* Bash of the Deep will deal lots of damage during the laning phase.
* Mana Shield can tank most of the damage from Reaper's Scythe; with sufficient mana, the kill threshold drops significantly.
* Necrophos has a movement speed equal to Medusa, and is easy to chase down with a slowing item in Medusa's inventory.
* If Medusa activates Stone Gaze before Spirit Breaker reaches her with Charge of Darkness, the charge will inevitably fail.
* Medusa has three ways to counter Spirit Breaker's Charge of Darkness: Stone Gaze can disable Spirit Breaker's Charge of Darkness if he faces Medusa directly.
Aghanim's Scepter upgraded
Mystic Snake can disable Spirit Breaker and cancel his Charge of Darkness if it hits him. And
Cold Blooded provided by
Aghanim's Shard that can cast a single-targeted
Mystic Snake at Spirit Breaker if he uses Charge of Darkness on her.
* Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation. And to make things worse, Spirit Breaker is not a common
Diffusal Blade nor
Disperser wielder to counter this problem at all.
* Overall, any attempt for Spirit Breaker to gank and kill Medusa will hurt him more than the other way around.
* Slardar can reveal Clinkz with Corrosive Haze and make him easy to kill, and his
Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
* Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Additional:
* Bounty Hunter's Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
* Heroes with spells that negate invisibility such as Bounty Hunter,
Zeus and
Slardar prevent her from saving her allies with Moonlight Shadow.
* Heroes who can provide True Sight are always credible threats: Slardar,
Bounty Hunter, especially
Zeus since his
Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.
* Heroes with Linken's Sphere as core item: Weaver,
Morphling,
Medusa.
* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade:
Bounty Hunter,
Slardar,
Spectre,
Zeus,
Spirit Breaker.
* Any long duration disables that can pierce through both, Pierce The Veil and Black King Bar are devastating against Muerta:

* Slardar can attack through Plague Wards and gain
Bash of the Deep charges, and
Templar Assassin can spill
Psi Blades through Plague Wards too.
* Crystal Maiden's already low armor and easily interruptible ultimate,
Freezing Field can make Slardar her worst nightmare.
Crystal Maiden also often builds
Glimmer Cape which is revealed by Corrosive Haze.
* Slardar can chase Dragon Knight down with
Guardian Sprint and stun him with both
Slithereen Crush and his passive
Bash of the Deep. He can also use
Corrosive Haze to whittle Dragon Knight's armor.
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven,
Omniknight,

* 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.
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina,
Zeus.
* Slardar does not do well against multiple targets, as his only way to damage multiple targets is Slithereen Crush.
* Meepo's Earthbind will root Slardar, making him unable to chase/escape for the time being. Also,
Poof's low cooldown and high damage can burst Slardar down rather quickly.
* Heroes who can stun multiple units at once: Dark Willow,
Spirit Breaker,
Slardar,
Invoker, and
Tidehunter.
* Poof won't damage Medusa and she can use Stone Gaze to disable all of Meepo's clones.
* Mystic Snake will easily become the bane of Meepo early game.
* Heroes that are hard to gank: Axe,
Death Prophet,
Phantom Lancer,
Slark,
Centaur Warrunner,
Bristleback,
Medusa,
Mars.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Should Luna choose to buy Manta Style, Medusa will be able to kill illusions from them with
Split Shot and
Mjollnir, which is a common item on Medusa.
* Mystic Snake allows Medusa to easily harass Luna and steal mana from her, preventing Luna from retaliating with
Lucent Beam.
* Medusa can survive Eclipse thanks to
Mana Shield, which can cause Luna to struggle greatly in bursting down Medusa and force her to buy
Diffusal Blade and it's upgrade
Disperser.
* Even with Black King Bar, Medusa's
Stone Gaze will still be able to disable Luna, which could even discourage her from counter-initiating with Eclipse.
Additional:
* Should Luna choose to buy Manta Style, Medusa will be able to kill illusions from them with
Split Shot and
Mjollnir, which is a common item on Medusa.
* Mystic Snake allows Medusa to easily harass Luna and steal mana from her, preventing Luna from retaliating with
Lucent Beam.
* Medusa can survive Eclipse thanks to
Mana Shield, and since Luna is not a hero that often goes for
Diffusal Blade, she will struggle greatly in bursting down Medusa.
* Even with Black King Bar, Medusa's
Stone Gaze will still be able to disable Luna, which could even discourage her from counter-initiating with Eclipse.
* For the same reasons, Medusa makes a very powerful ally for Luna when they are in the same team.
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter,
Bristleback,
Slardar.
* Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* Corrosive Haze's armor reduction makes Bristleback much less tanky.
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer,
Magnus,
Medusa, and
Anti-Mage.
* The brutal physical damage of Slithereen Crush and
Bash of the Deep can quickly remove Void Spirit's shield and stun him for a while.
* Corrosive Haze provides vision of Void Spirit while he is running away and
Guardian Sprint allows Slardar to quickly close the gap
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker,
Legion Commander,
Axe,
Puck, and
Slardar.
* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* Medusa can also kill Eidolons with her Mystic Snake that can also greatly damage Enigma and drain some of his mana.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating and landing an effective
Black Hole exceedingly difficult, because
Stone Gaze can cancel Enigma's
Black Hole even through spell immunity, which can discourage Enigma from even trying to initiate with
Black Hole.
Additional:
* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating — and landing an effective
Black Hole exceedingly difficult.
Stone Gaze can cancel Enigma's
Black Hole even through spell immunity, which can discourage Enigma from initiating with
Black Hole.
* Bloodseeker's
Rupture forces Slardar to stay still during fights, preventing Slardar from using Guardian sprint to move in and out of fights. This takes away the ability to initiate and re-initiate with Slithereen Crush's low cooldown. Due to the increased move speed from Guardian Sprint, Slardar can lose health at about 160% the rate of normal heroes while under
Rupture. Bloodseeker's
Thirst also gives him enough move speed so that he's one of the few heroes who can outrun or catch up to a Slardar during Guardian Sprint.
* Mana Shield makes it very difficult for Bloodseeker to gain his Thirst bonuses.
* Rupture rarely kills Medusa through Mana Shield.
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Additional:
* Medusa is a fairly immobile hero that deals damage around her with Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
* Slardar can use Guardian Sprint with
Blink Dagger or
Shadow Blade to get close, and
Slithereen Crush will stun Sniper and slow him, making him vulnerable to Slardar's teammates.
* Corrosive Haze lowers Sniper's armor and makes Sniper's
Shadow Blade useless, easily killing him with a few attacks.
* Anti-Mage easily destroys Mana Shield with Mana Break, especially once he has
Manta Style.
* Anti-Mage effectively avoids Stone Gaze with Blink, and can reinitiate after its duration is over.
Additional:
* Mana Break burns Medusa's mana easily, especially when coupled with a
Manta Style.
* Can easily initiate on Medusa with Blink, burning her mana or forcing her to use Stone Gaze.
* Mana Void is effective against Medusa's big mana pool and mana usage, presenting a huge hazard to Medusa's allies around her since her Mana Shield still gives her some protection if she has mana.
* Slardar deals entirely physical damage. He does not have to worry about Counterspell.
* Slithereen Crush and
Bash of the Deep prevent Anti-Mage from using Blink, the latter even if Anti-Mage activates
Black King Bar.
* Corrosive Haze allows allies to take down Anti-Mage before he has a chance to Blink, and maintains vision over him even if he does Blink away.
Additional:
* Slithereen Crush and Bash of the Deep deals physical damage, bypassing the magic resistance bonus from Counterspell
* Corrosize Haze significantly increases the damage dealt against Anti-Mage, and makes it harder for him to flee with Blink, although Anti-mage can block its casting with with Counterspell
* With Smoke Screen, Riki will silence and catch Medusa in a surprise with high miss chance flushing her from positions easily in team fights.
* He can deal a huge amount of damage through Cloak and Dagger, even through Mana Shield.
* Corrosive Haze works much like
Track, giving the enemy team vision over Riki. While it doesn't give a movement speed or gold bonus, it instead can melt Riki's armor and Slardar can use
Guardian Sprint to catch up to him.
* Slardar's Aghanim's Shard, causes
Slithereen Crush to apply Corrosive Haze even if Slardar does not have vision over him.
Additional:
* Corrosive Haze makes Riki completely vulnerable to Slardar and his allies, as Riki has no easy way of dispelling it.
* Slardar's physical damage with Slithereen Crush and Bash of the Deep amplified by Corrosive Haze can easily kill Riki.
* Ursa's status resistance from Enrage reduces duration of Medusa's Stone Gaze.
* Ursa can stack damage with Fury Swipes easily against her Mana Shield in a prolonged team match.
Additional:
* Medusa's tankiness doesn't help her very much against Fury Swipes in long teamfights.
* With no escape mechanism and a slow movement speed, getting jumped on by Ursa usually spells a quick end for Medusa in the early game.
* Slardar is one of the few meele heroes who can lane against Ursa in the early game, out harassing him with Bash of the Deep, and running away from a bad engagement with Guardian Sprint
* Corrosize Haze can force Ursa to cast Enrage defensively instead of offensively
* With Corrosize Haze, Slardar's team can quickly dispatch of Roshan, denying one of Ursa's greatest advantages
* Burning Spear's damage over time can rapidly burn Medusa's mana and health alike.
* Inner Fire can slow and disarm Medusa and also allow Huskar to follow up with Life Break.
* Corrosive Haze and
Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.
* Vendetta burns a significant amount of mana on hit, and the damage from the ability drains Medusa's mana pool even further.
* Due to the passive nature of Mystic Snake and Split Shot, it can possibly proc Nyx's Spiked Carapace if he's within range of Medusa's abilities and isn't invisible.
* Medusa lacks single target damage, making Nyx with Aghanim's Scepter extremely hard to deal with if Medusa is the team's main damage source.
Additional:
* With her passive Split Shot, Medusa can be easily interrupted by Spiked Carapace during combat, especially during her precious
Stone Gaze.
* Mana Burn quickly destroys Mana Shield, especially if Medusa only increases her mana pool by bolstering intelligence (which has the added bonus of increasing Mana Burn's damage).
* Uncontrollable damage from Mystic Snake and
Split Shot can trigger Spiked Carapace.
* Medusa lacks single target damage, making a Burrowed Nyx Assassin hard to kill.
* Corrosive Haze hinders Nyx Assassin's ganking attempts with
Vendetta, as well as reducing his armor and make him very vulnerable due to his low health pool.
* Guardian Sprint allows Slardar to catch up with Nyx Asssassin and finish him off if he has vision over him.
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky:
Riki,
Naga Siren,
Terrorblade,
Juggernaut,
Spectre,
Slark.
* Slardar's
Slithereen Crush allows him to stun Spectre and illusions, and
Corrosive Haze prevents her from juking with
Spectral Dagger.
* Axe can take advantage of Medusa's awfully low HP to insta-kill her with Culling Blade, making it extremely difficult for her to farm for items to compensate for the lack of strength during early and mid-game while Axe is continuously harassing around.
* Mana Shield reduces the effectiveness of Counter Helix.
* Stone Gaze makes it very difficult for Axe to initiate on Medusa and her allies.
