Arctic Burn
Cold Embrace
Able to force her enemies to attack their own ally
Where most dragons originate fire, the Winter Wyvern stores unfathomable cold. Soaring over the treeline, she breathes a blistering chill, causing painful Burning Colds. Gentle with her companions, she encases them in an Icy Cocoon, freezing them solid while healing them in curative magic. Auroth has no time for would-be dragon-slayers. Should the enemy be foolish to gather, her Winter's Curse compels her attackers to turn against one another. As frozen crystals form inside her gullet, she blasts the gathering with Icy Splinters that shatters upon impact of closely packed foes.

Winter Wyvern minimap icon.pngAuroth, the Winter Wyvern
▶️ "Some breathe fire. I breathe ice."
Like many great poets, Auroth just wants time to write, but the Winter Wyvern's life is full of interruptions. The epics of the Eldwurms have a long and colorful history, but some fear that the remaining dragon scholars are not as prolific as they once were, with few lines added to the Eldwurm Eddas since the last age of greatness. Auroth laments: "We forget that there is more to life than triumph and dominion over enemies. We must also live our lives in the pursuit of creative expression." She embarks on research expeditions, collecting books for inspiration. But all this research can be terribly distracting, and she spends less time writing than she should. Although she knows she should be lurking in her lair, adding to the Eddas, she finds herself engaged in epic battles against powerful enemies. She loots castles, raids ancient libraries... and if she happens to heap glory on herself in the process, she tells herself that it's merely a side effect of her research. The fact is, while her skill and power on the battlefield are legendary, her scholarly travails have thus far hardly been the stuff of literary acclaim. But she is not content to stand as a protagonist of heroic lore. She wishes also to create it.

No Target
(Upgradable by Aghanim's Scepter. Toggle)
Self / Enemies
Winter Wyvern soars upon an arctic wind, granting her unobstructed movement and allowing her to exhale a blistering chill into each attack. While soaring, her attacks travel further and faster, and slow enemies with a burning freeze that strips them of 6%/7%/8%/9% of their current health each second. Her sight is also hardened against night's chill, granting her 400 additional vision range at night while soaring.

Modifiers [?]
The same organ where some dragons stoke their inner flame is, in Auroth, a crucible of unimaginable cold. From deep within her frosty gullet, an exhalation sends enemies into burning agony.


  • Interrupts Winter Wyvern's channeling abilities upon cast.
  • Turns Winter Wyvern into a flying unit, allowing her to fly over impassable terrain, trees, units and buildings for its duration.
  • Each enemy can only receive the debuff once per cast. Successive attacks on the same target neither stack, nor reapply, nor refresh the duration.
  • The attacks first apply the debuff, then their own attack damage.
  • Deals damage in 1-second intervals, starting 1 second after the debuff is placed, resulting in 10 instances.
    • Can deal up to 27%/30%/34%/38% (Talent 35%/40%/44%/48%) of the target's current health as damage (before reductions), assuming nothing else affects the target's health.
  • Since the damage per second is based on a percentage of the target's current health, it can never kill an enemy by itself.
  • Destroys trees within a 175 radius at the end of the duration.
  • With Aghanim's Scepter icon.png Aghanim's Scepter, Arctic Burn turns into a toggle ability.
    • No longer interrupts Winter Wyvern's channeling abilities upon toggling On / Off.
    • Removes the 1 attack per target limit, allowing her to reapply, refresh the debuff with successive attacks on the same target.
    • Activating the ability costs 100 mana.
    • Drains Winter Wyvern's mana in 1-second intervals, starting 1 second after toggling.
    • If toggled On, Arctic Burn continues working even when silenced, disabled, or hidden.

Splinter Blast icon.png
Launches a ball of brittle ice towards an enemy. The ice shatters on impact, leaving the primary target completely unaffected, while hurling damaging splinters into nearby enemies in a 500 radius. Enemies struck by these splinters are slowed by 30%.

Cast Range: 1200
Splinter Search Radius: 500 (Talent 900)

Blocked upon impact.
Can partially be disjointed.
Initial projectile is not disjointable.
Secondary projectiles are disjointable, except via invisibility.
Modifiers [?]
Produced slowly by specialized vesicles in her frozen gullet, Winter Wyvern blast shards of ice at her enemies.


  • The initial projectile travels at a speed between 650 – 4000. It adapts so that it reaches the target in 1 second.
    • This means when the target gets more than 4000 range away on cast, it takes more than 1 second to reach it.
    • Vice versa, if the target gets closer than 650 range on cast, it takes less than 1 second to reach it.
  • However, the secondary projectiles travel at a speed of 800.
  • The splinters first apply the damage, then the stun, then the debuff.
  • The Splinter Blast stun Talent talent only affects the secondary targets, like the damage and slow.
    • The stun does not replace the slow. The slow is still applied, effectively slowing hit units for 2.5 seconds.

From winter's heart comes a cold, healing embrace. The ice slows the blood and allows the spell to better work its curative magic.


  • Stuns the allied target and turns it immune to physical damage. The target can still be attacked and affected by other damage types.
  • Heals for 7.5/8.75/10/11.25 (Talent 13.75/15/16.25/17.5) + 0.44%/0.63%/0.81%/1% health in 0.25-second intervals, starting 0.25 seconds after the buff is placed, resulting in 16 instances.
    • Can heal up to 120/140/160/180 (Talent 220/240/260/280) + 7%/10%/13%/16% of a unit's max health over its full duration.
  • With Aghanim's Shard icon.png Aghanim's Shard, losing the buff in any way causes Splinter Blast secondary projectiles to be released based on its current level.
    • Splinter Blast notes fully apply. If it is not learned, no projectiles are released.
    • Splinters released this way do not require vision, and can target invisible units and units inside the Fog of War.
    • However, unlike the projectiles of a regular cast, these projectiles are disjointed by invisibility.

Winter's Curse
Winter's Curse icon.png
Winter Wyvern freezes an enemy in place while striking those nearby with a maddening curse which causes them to attack their frozen ally with increased attack speed. The frozen ally and those cursed to attack their ally are immune to all damage from their enemies with the exception of Winter Wyvern or her controlled units.
Cast Animation: 0.3+1.37
Cast Range: 700/750/800
Radius: 525
Curse Damage Reduction: 100%
Curse Attack Speed Bonus: 65
Duration: 4.5/5/5.5 (Talent 6/6.5/7)
Nearby Allies Check Timer: 2.5
Cooldown: 90/85/80
Mana: 250
Partially pierces spell immunity.

Taunt persists if debuff was placed before spell immunity.
Partially blocked by Linken's Sphere.

Can be used by illusions.
Illusion Notes:

Modifiers [?]
The oldest of the bookwurm's spells, this curse lends truth to the old saw: sometimes the enemy of my enemy is my enemy still.


  • Stuns and provides True Sight over the target, while its allies within the radius get taunted, forcing them to attack the primary target.
    • Enemies that enter the radius after cast is also taunted for its remaining duration.
    • If no valid enemies are within 525 radius for a total of 2.5 seconds, the debuff gets removed.
    • Does not affect or check for spell immune, invulnerable, or hidden enemies, wards or buildings within the radius.
    • Only affects units allied to the target. This means when cast on an enemy, neutral creeps are not taunted, and vice versa.
    • Despite not getting taunted when targeting an enemy, neutral creeps still prevent the curse debuff from being removed prematurely.
  • The taunt is based on an aura, with an infinite linger duration. The debuff gets cleared when the debuff on the primary target expires, or when the target dies.
    • This means the taunt sticks on the affected units, and getting moved outside the radius does not free the unit from the taunt.
    • This also means the taunt sticks even if the debuff got removed on the primary target due to no enemies being within the area.
  • The taunt area is centered on the primary target and follows them if they get forcibly moved.
  • Applies generic incoming damage reduction on the targets. Stacks additively with other sources of generic incoming damage manipulation.
    • This means that sources of generic incoming damage amplification can be used to counter the effect.
    • The reduction affects all damage that is not flagged as HP removal the targets take from any source except for Winter Wyvern.
  • If the target gets killed during the curse, Winter Wyvern gets credit for the kill.
    • Has a lower priority than Reaper's Scythe, so if affected by both, Reaper's Scythe takes priority.
    • Has a higher priority than Ice Blast, so if affected by both, Winter's Curse takes priority.
  • Does not disable any abilities. However, most passive abilities do not affect allied units.
  • When the primary target dies, the taunt effect ends immediately.

Recommended Items[]

Starting items:

  • Tango icon.png Tango sustains health in the laning stage to deal with harassment.
  • Clarity icon.png Clarity replenishes mana early, important since Winter Wyvern's abilities are expensive in the early game.

Early game:

  • Magic Stick icon.png Magic Stick gives Winter Wyvern burst health and mana, which can allow her to survive just long enough to cast one more important spell in a teamfight.
  • Boots of Speed icon.png Boots of Speed will help improve Winter Wyvern's lackluster movement speed, particularly useful in order to get in position or chase/escape with Arctic Burn.
  • Wind Lace icon.png Wind Lace also provides cheap movement speed, great for poor and slow supports.

  • Arcane Boots icon.png Arcane Boots increases mana pool and gives a way to replenish mana. Can be disassembled to build into Holy Locket icon.png Holy Locket.
  • Glimmer Cape icon.png Glimmer Cape is a cheap but powerful utility support item in Winter Wyvern's hands. It can be cast on herself to allow her to invisibly approach the enemy during initiations, or can be targeted on an ally under the effects of Cold Embrace to fortify their magic resistance on top of nullifying physical damage.
  • Spirit Vessel icon.png Spirit Vessel is natural upgrade of Urn of Shadows icon.png Urn of Shadows and gives her additional single-target damage.

Late game:

  • Holy Locket icon.png Holy Locket increases the healing from Cold Embrace and can be easily built from upgrade of Magic Wand icon.png Magic Wand and disassembled {{I|Arcane Boots|30px}.
  • Mekansm icon.png Mekansm gives Winter Wyvern more attributes and armor, and the active gives her another method with which to heal teammates on top of Cold Embrace.
  • Guardian Greaves icon.png Guardian Greaves restores massive amount of health and mana to Winter Wyvern and her allies. Mend also removes negative debuffs that may hinder her from using abilities.
  • Force Staff icon.png Force Staff is a cheap multipurpose item that greatly increases Winter Wyvern's utility. The intelligence and health regeneration give her more mana and better roaming capability, and the active can help her to position herself more easily for casting spells, particularly to get Winter's Curse off on an important target. It can also move allies to safer place during Cold Embrace.

Situational items:

  • Aether Lens icon.png Aether Lens gives mana and mana regeneration, as well as increased cast range to allow usage of abilities further away from dangerous enemies.
  • Meteor Hammer icon.png Meteor Hammer provides area stun and damage to follow Winter's Curse, and supplements Winter Wyvern's pushing power with some building damage.

  • Blink Dagger icon.png Blink Dagger is a great way to increase Winter Wyvern's mobility and allows her to more easily initiate with Winter's Curse.
  • Lotus Orb icon.png Lotus Orb applies basic dispel on target to remove some debuffs and gives them a shield to reflect single target spells, which may deter enemies from using abilities on the target.
  • Aghanim's Scepter icon.png Aghanim's Scepter allows toggling of Arctic Burn and refreshing the debuff with following attacks, a great item to control enemy heroes from long distance; the movement speed bonus makes positioning really easy before and during fights; however, the massive mana drain means it should never be purchased early.
  • Scythe of Vyse icon.png Scythe of Vyse greatly improves Winter Wyvern's intelligence and provides all-around attributes as well as plenty of mana regeneration to fuel her costly spells. The hex is a powerful hard-disable that greatly increases her ability to contribute to ganks and teamfights.






  • Winter Wyvern made her first official Dota 2 appearance in the New Bloom trailer "The Coming of the Year Beast" which was showcased the first time after the finals of the Dota 2 Asia Championship 2015 on the 9th of February 2015. The trailer video was later posted on the official Dota 2 blog as part 1 of the New Bloom event.
    • Her next official appearance was in the comic "The new neighbors", which was posted on the 10th of February 2015 on the official Dota 2 blog. In the comic, she is depicted as an "artistic" dragon with interests in books who does not follow the traditional behavior of dragons razing cities to the ground.
  • Much like Legion Commander minimap icon.png Legion Commander, who is also voiced by Merle Dandridge, the gender of Winter Wyvern was changed from male to female with the transition from DotA to Dota 2.[1]
  • In DotA, Winter Wyvern makes use the model of the Warcraft 3 version of a frost wyrm, a well known undead dragon type from the Warcraft universe.[2]
  • Winter Wyvern's response when meeting Axe minimap icon.png Axe as an ally, ▶️ "In this world, nothing is certain but ice and axes" is a nod to a quote by Benjamin Franklin, which states: "In this world nothing can be said to be certain, except death and taxes."[3]
  • Winter Wyvern's response, ▶️ "Winter is coming. Winter Wyvern that is." is a reference to Game of Thrones, specifically the motto of the House of Stark: "Winter is coming."[4]
  • Winter Wyvern's rivalry line towards Dragon Knight minimap icon.png Dragon Knight ▶️"I knew Slyrak, Dragon Knight. You're no Slyrak." is a reference to Lloyd Bentsen's political quip "... I knew Jack Kennedy... Senator, you're no Jack Kennedy".[5]
  • When the hero's abilities were showcased in The International 2016, Winter's Curse was cast on a Naga Siren, which caused her team mates, Gyrocopter, Ancient Apparition, Earthshaker and Storm Spirit, to kill her. This is in reference to how Aui_2000, who played Naga during Game 4 in the finals of the previous International against CDEC, was subsequently kicked out of the team.
