Winter Wyvern
* Arctic Burn and Splinter Blast's debuffs are can be dispelled with with 
Dark Pact. Arctic Burn also cannot be used to escape against 
Pounce.
* Even though Cold Embrace can protect it's owner from Slark's direct attacks, Slark can still gain 
Essence Shift stacks from attacking heroes affected by it.
* However, Essence Shift works against allies, and Slark's low health pool means that if he's the target for Winter's Curse, he will go down very quickly as Winter's Curse cannot be dispelled at all.
Pangolier
* Dark Pact easily purges away both slow and disarm effect from Lucky Shot.
* With Pounce now applying leash to the target, Pangolier is helpless against Slark since both his Swashbuckle and Rolling Thunder will be disabled. Pounce also help Slark to easily escape from Rolling Thunder.
Winter Wyvern
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, 
Enigma, 
Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain, 
Shadow Fiend, 
Treant Protector, 
Underlord, 
Winter Wyvern, 
Witch Doctor, 
Zeus.
Pangolier
* Heroes with spell immunity can still be disabled by Fiend's Grip and damaged by Brain Sap: 
Juggernaut, 
Lifestealer, 
Pangolier.
Winter Wyvern
* 
Cold Embrace makes its target immovable, allowing Ancient Apparition to easily land Ice Blast, or a Cold Feet stun.
* Ice Blast also negates healing from Cold Embrace.
Additional:
* 
Ice Blast disables the healing component of Cold Embrace, making it essentially a 4 second stun on an ally and a perfect setup for Ice Blast.
* If 
Cold Feet is cast on an Allied hero affected by Cold Embrace, it will almost guarantee the Ally comes out stunned.
Winter Wyvern
* All of Tinker's damage is magical and pure, which makes Cold Embrace a good setup for his nukes.
* Winter's Curse is very hard to cast on Tinker because he usually stays in the back-lines in team-fights. In turn, Tinker has mediocre attack damage and will contribute very little when he is cursed to attack an ally. He can also save his ally under Winter's Curse effect with 
Ethereal Blade and 
Defense Matrix.
Winter Wyvern
* Winter Wyvern cannot handle the Zombies created by Undying's Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well.
Additional:
* Winter Wyvern cannot handle the Zombies created by 
Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy 
Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well, since it is magical.
Winter Wyvern
* Guardian Angel completely counters 
Winter's Curse if Omniknight is able to cast it.
Additional:
* 
Guardian Angel completely counters Winter's Curse, allowing his team to survive Winter Wyvern's initiation.
* 
Purification and 
Repel are very useful against Arctic Burn, Splinter Blast and Winter's Curse as well.
Pangolier
* 
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.
Winter Wyvern
* Even though Ursa is a hero who relies on direct attacks to be effective, 
Fury Swipes does not work on allies if Ursa is affected by Winter's Curse, mitigating a majority of Ursa's damage. In addition, Ursa's unimpressive attack speed and attack damage without 
Overpower and Fury Swipes means that he deals little to no damage to allies during Winter's Curse.
* 
Aghanim's Scepter upgraded 
Enrage allows Ursa to survive Winter Wyvern's initiation with Winter's Curse.
Pangolier
* 
Illusory Orb and 
Waning Rift provides great mobility, allowing Puck to catch up Pangolier when he is attempting to disengage with his own skills.
* 
Dream Coil's leash act almost as a literal silence to Pangolier, disabling half of his arsenal and also piercing his spell immunity during Rolling Thunder. Also Dream Coil's very long duration will make Pangolier wasting his entire ultimate rolling in place.
Additional:
* Dream Coil and Wanning Rift prevent Pangolier from using 
Swashbuckle and 
Rolling Thunder. If Puck has Aghanim's Scepter, Dream coil will stop Rolling Thunder from moving entirely.
Pangolier
* 
Charge of Darkness can be used to chase down Pangolier if he escapes with Swashbuckle or Rolling Thunder.
* 
Nether Strike ignores Rolling Thunder's spell immunity, and will still hit Pangolier if he rolls or dashes away.
Pangolier
* Rupture works through Rolling Thunder and Swashbuckle, greatly reducing Pangolier's mobility.
Additional:
* 
Thirst provides constant sight and speed to Bloodseeker, allows him to catch up a fleeing Pangolier through all of his mobility.
* 
Rupture is a great threat to Pangolier, causing him to take heavy damage if he uses Swashbuckle and especially Rolling Thunder, forcing him to stop his ultimate prematurely, or keep rolling to his death.
Pangolier
* 
Soulbind ignores spell immunity, forcing Pangolier to roll in place during his ultimate as well as anchoring the other victim to his vicinity.
Winter Wyvern
* Cold Embrace is a perfect setup for Mystic Flare.
* Winter Wyvern is a spellcaster, and the 6 second silence from Ancient Seal can prevent her from contributing much.
* Because Skywrath Mage tends to stay back in fights, Winter Wyvern will have to get close to a teamfight to cast Winter's Curse on him. And if she chooses to cast it on one of his allies, his low attack speed and damage means that he won't do much.
* However, bear in mind that Skywrath Mage has seriously awful armor, and that can make him an adequate target to being turned against his own team with Winter's Curse, which can result in his death quickly.
Additional:
* Cold Embrace is the perfect setup for 
Mystic Flare, and his 6-second silence is good against Winter Wyvern in general.
Pangolier
* 
Shield Crash is a great area-of-effect ability on Rubick primarily for farming.
* Swashbuckle is a great reposition and damage ability on the hands of Rubick.
* Note that Rubick does not have 
Lucky Shot, so the ability might be less effective as a source of damage.
* Pangolier may build items such as 
Maelstrom or 
Diffusal Blade to add up attack multipliers to the ability, and Rubick can choose to build similar items should he choose the route.
* Rolling Thunder is a unique ability that allows Rubick to jump in the center of teamfight while protected by Spell Immunity, creating chaos and possibly chain stun the enemy team.
* Rolling Thunder negates the collision damage and stun from Pangolier's Rolling Thunder.
* Rubick uses the fixed 0.15 second cast time when casting Rolling Thunder, making it faster than Pangolier himself.
* Rubick can still use his abilities during Rolling Thunder - throwing an enemy en route by casting 
Telekinesis can be a good idea.
* The decision to steal Rolling Thunder should be made quickly as Pangolier cast Shield Crash very often during Rolling Thunder.
Pangolier
* 
Ice Shards can easily interfere with Rolling Thunder, making him stuck inside the arc and wasting his ultimate. Do not panic and use Shield Crash to get out of that position.
* 
Snowball helps Tusk and his allies follow a fleeing Pangolier, keep in mind that the Pangolier can always counter-initiate with his Rolling Thunder.
* 
Walrus PUNCH! deals heavy damage even during his Rolling Thunder.
Winter Wyvern
* Cold Embrace is no salvation against 
Lucent Beam and 
Eclipse.
* 
Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by 
Lunar Blessing than Winter Wyvern when affected by Arctic Burn.
Additional:
* Cold Embrace is no salvation against Lucent Beam and Eclipse.
* Moon Glaives will not hit a hero affected by Winter's Curse, making it weak against allies, but strong versus enemies.
* Luna has better night vision provided by Lunar Blessing than Winter Wyvern when affected by Arctic Burn.
Pangolier
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): 
Vengeful Spirit, 
Keeper of the Light, 
Huskar, 
Dark Seer
Pangolier
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Pangolier
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Pangolier
* Heroes with considerable mobility can easily escape from a rolling Pangolier: 
Anti-Mage, Queen of Pain, 
Void Spirit, 
Storm Spirit, 
Ember Spirit, 
Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.

Pangolier
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: 
Drow Ranger, 
Sniper, 
Templar Assassin, 
Arc Warden
Winter Wyvern
* Heavy nukers will do well against Cold Embrace (
Lina, Zeus etc).
Additional:
* Any ally that Winter Wyvern tries to save with Cold Embrace can still be damaged by all of Zeus's spells.
* If Winter Wyvern tries to juke vision by flying up a cliff or in the trees, Zeus can gain vision there with Lightning Bolt or Thundergod's Wrath.
* If Zeus is forced to attack an ally by Winter's Curse, his unimpressive attack damage and attack speed means they won't be hurt much by him. Zeus will also stay near the back of fights away from his allies, making a deadly Curse less likely.
Pangolier
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Pangolier
* 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
Pangolier
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, 
Meepo, 
Crystal Maiden, 
Dark Willow, Underlord, 
Naga Siren
Pangolier

Winter Wyvern
* Heroes with the ability to heal allies will not be able to heal heroes affected by 
Doom: 
Chen, 
Dazzle, 
Io, 
Oracle, 
Omniknight, Witch Doctor, Winter Wyvern, 
Abaddon, etc.
Winter Wyvern
* Heavy nukers will do well against Cold Embrace (Lina, Zeus etc).
Winter Wyvern
* Cold Embrace is the perfect setup for all his nukes - 
Chaos Meteor, 
E.M.P. and especially global 
Sun Strike.
Pangolier
* Heroes with abilities which have a built-in spell immunity: Lifestealer, Juggernaut, Pangolier.
Winter Wyvern
* Cold Embrace is a death sentence against Pugna, since its the perfect setup for all his abilities, especially 
Life Drain.
* 
Decrepify can be cast to save the ally under Winter's Curse effect, wasting most of its duration.
* Winter Wyvern's abilities require a lot of mana, allowing 
Nether Ward to deal lots of damage.
Pangolier
* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, 
Pugna, Witch Doctor
Pangolier
* Pangolier will proc Retaliate several times if he attempts to use Swashbuckle on Centaur Warrunner.
* Centaur can cast Stampede to allow all of his allies to easily avoid Rolling Thunder.
* Centaur's tankiness makes it hard for Pangolier to burst him down in the late game.
Additional:
* When Swashbuckle hits Centaur Warrunner, 
Retaliate will deal significant damage, as it procs off every strike made.
* 
Stampede helps allies avoid or disengage from Pangolier during Rolling Thunder, as well as neutralizing the slow debuff from Lucky Shot.
Winter Wyvern
* Winter Wyvern's 
Arctic Burn can also be a useful tool against Centaur, who generally has very high health. Winter's Curse on Centaur can cause Retaliate to damage allies who are forced to attack him.
Pangolier
* 
Chronosphere's large obstacle denies Pangolier the room to roll around during teamfights, as well as wasting his ultimate's duration.
Winter Wyvern
* Any hero that can nullify effects of Chronosphere: (Keeper of the Light with Aghanim's Scepter during daytime, Winter Wyvern), banishing him or Faceless Void (Outworld Destroyer, 
Shadow Demon, Earth Spirit with Aghanim's Scepter) or protecting him in other ways (Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.
Winter Wyvern
* Cold Embrace saves allies from dying in Duels.
* Winter's Curse turns Legion Commander's high damage against her allies, giving the enemy team little time to react.
* However, Winter Wyvern lanes very poorly against Legion Commander due to Press the Attack removing all the debuffs she can give. Winter Wyvern also has little chances of surviving if she gets Dueled herself.
Additional:
* Cold Embrace is very effective against 
Duel.
* Also, casting Winter's Curse at 
Legion Commander while an ally is in a Duel will stun her for most of the duration, possibly preventing lethal damage dealt to your ally. It can also turn her high-damage against her teammate.
Pangolier
* Lucky Shot can disarm Legion Commander and reduce her armor, which can reduce her chances of winning a duel. If an ally is targeted, Pangolier can simply use Swashbuckle to inflict it on her.
* If an enemy Pangolier casts a well-timed Rolling Thunder before Legion Commander can cast Duel, it might result in her chasing down Pangolier until his or her ultimate ends, whichever duration ends first, resulting in an open window for enemy allies to target Legion Commander, making her vulnerable and susceptible to any source of attacks. If Legion Commander has an Aghanim's Scepter in her inventory, the risk of wasting a solid 8 seconds would result in a futile duel.
* Dueling Pangolier is normally a mistake, Pangolier can disarm you in the duel, and potentially gain some Duel damage, Only duel Pangolier if at least 1 ally is nearby, and he is on low health, And even then, be wary, A good duel can easily turn against you with one Lucky Shot (Due to Lucky Shot lasting 4 seconds).
Additional:
* Swashbuckle can be used to disarm Legion Commander while she is Dueling an ally, granting her opponent a considerable advantage, Lucky Shot lasts 4 seconds at most wasting Legion Commander's entire Duel, (Or half, if Legion Commander has the Scepter).
* Legion Commander will try not to duel Pangolier alone, as she will almost inevitably lose, thanks to Lucky Shot's disarm, If Legion Commander wants to duel a Pangolier, she must be with atleast a teammate, and if she has her scepter, 3 or 4 teammates.
* Legion Commander is often with her allies, allowing you to rack up some considerable damage resistance with Shield Crash.
Winter Wyvern
* 
Broodmother, 
Nature's Prophet, 
Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Pangolier
* Swashbuckle,Maelstrom or Diffusal Blade allow him to quickly destroy Phantom Lancer's illusions.
* Pangolier's high mobility allows him to easily escape from Phantom Lancer, through both Phantom Rush and Diffusal Blade.
* 
Phantom Rush will cause Phantom Lancer to be stunned by Rolling Thunder, or set himself up for a Shield Crash.
Additional:
* Pangolier's AoE abilities especially Shield Crash, are very effective against Phantom Lancer's illusions.
Winter Wyvern
* Cold Embrace protects targets affected by Reality Rift.
* Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* 
Splinter Blast deals decent area damage to Phantasm illusions.
* Arctic Burn's percentage-based damage quickly wears down Chaos Knight's high max health.
Additional:
* Winter Wyvern can make Chaos Knight's illusions attack the real one, provided the player knows who it is.
* Alternatively, Winter's Curse can make Chaos Knight and all his illusions attack one of his allies.
* Cold Embrace protects ally who is focused by Chaos Knight.
* Splinter Blast deals decent area damage to Chaos Knight's illusions.
* Chaos Knight's high health pool and tendency to not build magic resistance items will make Arctic Burn deal a lot of damage to him and his illusions.
Pangolier
* Heroes who are illusion based, or even heroes who frequently build Manta Style can be cleared quickly by Pangolier's high damage, or lose their damage ouput because of Lucky Shot: 
Chaos Knight, Naga Siren
Winter Wyvern
* Cold Embrace can heal herself or an ally, as well as protecting them from Clinkz's physical attacks and wasting his mana if Searing Arrows is on autocast.
* Winter's Curse allows Winter Wyvern to turn Clinkz's high damage and high attack speed against his allies, or take advantage of Clinkz's fragility if he can't use Skeleton Walk.
Pangolier
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: 
Terrorblade, 
Sven, 
Clinkz, 
Windranger, 
Alchemist, 
Dragon Knight, Legion Commander
Winter Wyvern
* Arctic Burn allows Winter Wyvern to escape Lycan, even when he uses his ultimate.
* Splinter Blast is very effective in dealing with Lycan's summons.
* Cold Embrace saves allies from Lycan's raw physical damage and can buy allies enough time to turn the tide of battle.
* Winter's Curse stops Lycan in his tracks and is very effective because of his summons.
Additional:
* All of Lycan's damage is physical which is totally negated by Cold Embrace.
* Lycan often moves around with large amount of creeps, wolves created by 
Summon Wolves and neutral creep dominated by 
Helm of the Dominator which can be easily cleared by Splinter Blast or used as a great source of damage by Winter's Curse. If you catch Lycan with creeps nearby and affected by 
Shapeshift using Winter's Curse on him will most certainly end up with his death.
Pangolier
* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, Enigma, 
Lycan
Winter Wyvern
* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Pangolier
* Swashbuckle can be used for Pangolier to escape or kill Broodmother's spiders. Combined with Lucky Shot Pangolier can potentially disarm Broodmother preventing her from lifestealing off enemies.
* Shield Crash can be used for wave clear to deal with Broodmother's spiders.
* Rolling Thunder can be used as an escape or a means of initiating on Broodmother.
Additional:
* Swashbuckle and Shield Crash quickly destroys Broodmother's spiderlings and spiderites.
* Lucky Shot's disarm is very valuable when dealing with a Broodmother during her 
Insatiable Hunger.
Pangolier
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, Meepo, Crystal Maiden, Dark Willow, Underlord, Naga Siren
Winter Wyvern
* Winter's Curse in late game is pretty much the end for Meepo or any of his nearby allies. Natural counter for Winter's Curse like 
Linken's Sphere or 
Lotus Orb is meaningless to her if she can land it on one of Meepo's clones.
Additional:
* Meepo's clones usually gets grouped in teamfight making any of them ideal target for Winter's Curse, forcing Meepo to literally kill himself. Also, unlike other heroes he cannot protect himself with Linken's Sphere.
* While Meepo's clones are grouped up, Splinter Blast will hit almost every clone, slowing Meepo and making him easier to fight.
Pangolier
* Pangolier's arsenal deals heavy damage in a wide area, make him deadly even for a Meepo with a high magic resistance.
* Shield Crash can easily give him a ridiculous 80% damage resistance (Becomes 100% if Pangolier gets his +5% Shield Crash talent, Or there is 5 Meepos), resulting in a near unkillable Pangolier in a short amount of time.
* Rolling Thunder disrupts Meepo's initiation or escaping.
* Swashbuckle can hit all of Meepo clones.
* Lucky Shot can disarm Meepo's clones.
Additional:
* Shield Crash gains its damage reduction bonus from all Meepo clones, and can be used even when rooted, allowing Pangolier to gain a massive amount of damage reduction (even more than 100%).
* With too many clone running around during combat, it is almost impossible for Meepo to avoid Rolling Thunder or Swashbuckle.
* Still, remember that a lone Pangolier can never escape from a ganking Meepo.
Winter Wyvern
* Broodmother, Nature's Prophet, Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Pangolier
* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, Enigma, Lycan
Winter Wyvern
* Terrorblade and his illusions deal huge damage, which might used against him and his team with Winter's Curse.
Pangolier
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: Terrorblade, Sven, Clinkz, Windranger, Alchemist, Dragon Knight, Legion Commander
Pangolier
* Pangolier's Lucky shot disarms her if procs making Unleash useless.
* Swashbuckle have a lower cooldown than Rebound so Pangolier can out maneuver her quite easily.
Additional:
* Pangolier's Lucky Shot disarms her if it procs, making 
Unleash useless.
* Swashbuckle will easily burn away Marci's already low mana pool with Diffusal Blade, an item commonly built on Pangolier.
* Swashbuckle's cooldown is shorter than 
Rebound, making it easy for Pangolier to outmaneuver her.
* Marci will get stunned if she tries to use Rebound while Pangolier is using Rolling Thunder, somewhat hindering her mobility in teamfights.
Pangolier
* 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
Winter Wyvern
* Cold Embrace mitigates Primal Roar's single-target initiation on allies.
* Winter's Curse can turn Beastmaster's summons and Inner Beast against his teammate.
Additional:
* Beastmaster's summons and 
Inner Beast are very useful to attack his cursed teammate.
* Cold Embrace effectively mitigates 
Primal Roar's single-target initiation on allies.
Pangolier
* Heroes with AoE abilities are a bane to Beastmaster's summons: Storm Spirit, Magnus, Pangolier.
Pangolier
* Swashbuckle is an auto attack and therefore ignores Mars' Bulwark.
* Shield Crash upgraded with Aghanim is an auto attack and therefore ignores Mars' Bulwark.
* Rolling Thunder makes him immune to magic, making Pangolier able to roll in and out of Mars' Arena Of Blood.
Winter Wyvern
* Cold Embrace can protect Troll Warlord's target, especially during Battle Trance.
* Winter's Curse can turn Troll Warlord's high physical damage and attack speed against his allies.
Additional:
* Cold Embrace will protect your ally from being damaged if he gets focused by Troll, although be careful as 
Fervor will keep gaining stacks even while Cold Embrace is active.
* Fervor works on allies.
* His high attack speed will help to kill his cursed ally faster.
Pangolier
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, Meepo, Crystal Maiden, Dark Willow, Underlord, Naga Siren
Winter Wyvern
* Winter's Curse and Splinter Blast can devastate Underlord's team when they are grouped up for the teleportation with 
Fiend's Gate.
* Cold Embrace can be used to heal Winter Wyvern's allies, and protect them from the attack damage from 
Atrophy Aura. Bear in mind, however, that the heroes affected by Cold Embrace are easy targets for 
Firestorm and 
Pit of Malice.
Pangolier

Winter Wyvern
* Winter's Curse, when directly targeted on Enigma, goes through 
Black King Bar, stopping Enigma's Black Hole channeling. It also turns his team against him, potentially killing him. Even if Enigma gets Linken's Sphere on top of Black King Bar, Splinter Blast can be used to pop Linken's Sphere, and Winter's Curse will stop Black Hole channeling.
* Splinter Blast can be targeted on an eidolon, killing off other eidolons and damaging nearby heroes as well.

* Pangolier's abilities which does not need to target and has big area of effect allows him to damage her even during 
Meld.
* Pangolier's high mobility easily shrug off the slow from 
Psionic Trap.
Winter Wyvern
* Cold Embrace can render the extra attack speed from 
Overcharge meaningless.
* Splinter Blast and Winter's Curse are very affective against Io, as it has to stay close to his 
Tethered target.
Pangolier
* Pangolier's high mobility allows Pangolier to escape from Visage's ganking attempt. Keep in mind that his familiars can easily interfere with your ultimate during casting time if they are able to scout your position.

Gravekeeper's Cloak charges.
Winter Wyvern
* Many physical-only single-target heroes like Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
