Mercurial, the Spectre, is a melee agility hero, adept at dealing pure damage to lone targets, and is powerful both offensively and defensively. Spectral Dagger provides a significant amount of mobility, allowing Spectre to go through objects, units and terrain while slowing foes that come in contact with the shadowy path left by her Spectral Dagger. Desolate allows her to inflict high pure damage to enemy heroes when she catches them alone. Dispersion reduces and reflects all damage, whether by attacks or spells, to an area around her. Dispersion gives her great durability, especially when equipped with items that provide health, armor, and damage block. Finally, her Haunt creates a malevolent spectral illusion to all enemy heroes in the map. Haunt lets Spectre wreak havoc in clashes and ganks, while her allies take advantage of the confusion. Spectre can use Reality during the Haunt, instantly teleporting her to her illusion to take its form. This lets her hound her victim anywhere on the map. Mercurial is a dangerous supernatural being, relentless as she can chase and stalk down her victim to a global range, unhindered by boundaries. Her kit allows her to play the role of the team's hard carry by applying an immense amount of pressure in late game team fights. More specifically, the damage reflection from Dispersion makes it disadvantageous for teams to focus her. Her abilities have a complex nature, and newer players should generally not play Spectre as she is extremely farm and level dependent. It is best to face Spectre with allied help and strength, as encountering her alone is not always the best option.


Spectre minimap icon.pngMercurial, the Spectre
▶️ "Among the Transcendencies, you would be thought ignoble."
Just as higher states of energy seek a lower level, the Spectre known as Mercurial is a being of intense and violent energy who finds herself irresistibly drawn to scenes of strife as they unfold in the physical world. While her normal spectral state transcends sensory limitations, each time she takes on a physical manifestation, she is stricken by a loss of self--though not of purpose. In the clash of combat, her identity shatters and reconfigures, and she begins to regain awareness. She grasps that she is Mercurial the Spectre--and that all of her Haunts are but shadows of the one true Spectre. Focus comes in the struggle for survival; her true mind reasserts itself; until in the final moments of victory or defeat, she transcends matter and is restored once more to her eternal form.


Spectral Dagger
Spectral Dagger icon.png
Self / Enemies
Spectre flings a dagger to draw a Shadow Path, dealing damage and slowing the movement speed of any enemies along the trail. Units hit by the dagger also trail a Shadow Path. While treading the path, Spectre phases through otherwise impassable terrain.
Cast Animation: 0.3+0.37
Cast Range: 1800
Effect Radius: 125
Damage: 75/130/185/240
Move Speed Slow/Bonus: 10%/14%/18%/22% (Talent 24%/28%/32%/36%)

Free Pathing Linger Duration: 1
Cooldown: 22/20/18/16 (Talent 14/12/10/8)
Mana: 130/140/150/160
Partially pierces spell immunity. Can target spell immune enemies, placing the trail and slow debuff on them. The slow debuff is inactive while spell immune.
Not blocked by Linken's Sphere. Procs only when secondary target while a hero was directly targeted. However, Spectral Dagger instantly reattempts to apply the debuff, thus wasting Linken's cooldown. No interaction with the primary target or when hit while the ground was targeted.
Buff modifier_spectre_spectral_dagger_path: Undispellable. Persists death.
Buff or Debuff, based on the target's alliance modifier_spectre_spectral_dagger_in_path: Dispellable with death only.
Buff modifier_spectre_spectral_dagger_path_phased: Dispellable with death only.
Debuff modifier_spectre_spectral_dagger: Dispellable with death only.
Mercurial's dagger eclipses the physical plane in shadow, a state in which mortals cower, but spectres thrive.


  • The Spectral Dagger travels at a speed of 800.
  • Can directly target heroes and creep-heroes. When targeting a hero, the dagger homes in on the target until reaching it.
  • When targeting the ground or creep-heroes, the dagger travels 1800 range in a straight line. It does not home in on creep-heroes.
  • Every enemy unit which comes within 125 range of the traveling dagger gets damaged.
  • Hit enemy heroes and illusions also receive the Dagger Path Creator debuff, making them trail a shadow path like the dagger itself.
    • This debuff also grants shared vision over the enemy heroes, revealing their silhouette when invisible.
  • Spectre and enemies gain the Spectral Dagger Path modifier while on the path, increasing her while decreasing the enemies' movement speed.
    • This modifier lingers for 4 seconds after leaving the path.
    • The modifier only refreshes from the same source. Meaning that Spectre will not be slowed by an enemy Spectral Dagger when she has the buff modifier.
  • Spectre also gains a hidden buff, which grants her unobstructed movement.
    • This buff lingers for 1 second after leaving the path.
  • The shadow path's segments last 12 seconds from the moment on they were created, not as the spell was cast.

Desolate icon.png
Deals bonus damage whenever Spectre attacks an enemy that does not have any allied units within a 425 radius around them.
Radius: 425
Damage: 18/32/46/60 (Talent 30/44/58/72)
Buff modifier_spectre_desolate: Undispellable. Persists death.
Often times, warriors find themselves alone with a vision of Mercurial - the fated question is if it is the true Spectre.


  • Desolate's effects are applied upon finishing an attack, regardless of whether the attack actually hits the target or not.
    • This means Desolate applies its effects even when the leading attack misses the target.
    • When used by ranged heroes, this means the effect is applied on projectile launch, not hit.
  • Desolate completely ignores nearby wards, buildings, invulnerable and hidden units.
    • This means that Desolate still deals its damage when the target only has any of the above as allies nearby.
  • Only checks for allies of the target, meaning nearby neutral creeps do not prevent it from dealing damage to units of the enemy team, and vice versa.

Damage done to Spectre is reflected on her enemies, leaving her unharmed. The effect lessens with distance.

A daunting task lies before enemies of Mercurial - killing a shadow with blade and magic.


  • Applies generic incoming damage reduction on Spectre. Stacks additively with other sources of generic incoming damage manipulation.
    • The reduction affects all damage Spectre takes that is not flagged as HP removal.
    • Increases Spectre's survivability against any damage by 9%/14%/19%/25% (Talent 15%/20%/27%/33%).
  • The reflected damage is applied to all targets within the radius, not only the original source.
  • Dispersed damage is returned as the same damage type as it was received.
  • Returns incoming damage before all manipulations. However, damage manipulation on the enemy still affects the damage normally.
  • Always reflects a percentage of the full damage value, no matter how much health Spectre had left when she received the damage.
    • This means it reflects overkill damage dealt to Spectre, so if a damage source exceeded Spectre's current health and killed her, the reflected damage is based on the full damage value.
  • Dispersion reflects the damage right before it is actually done to Spectre, so if both Spectre and an enemy would die to the damage simultaneously, the enemy is always killed first.
  • Reflected damage is not divided between enemies. All of them take the full reflected damage.
  • Reflects the full 8%/12%/16%/20% within a 300 radius from Spectre. Then the reflected damage decreases linearly up to a 700 radius from Spectre.
  • This is how much damage Dispersion reflects to enemies at certain distances:
    • 300 Distance: 8%/12%/16%/20% (Talent 13%/17%/21%/25%) of dealt damage.
    • 400 Distance: 6%/9%/12%/15% (Talent 9.75%/12.75%/15.75%/18.75%) of dealt damage.
    • 500 Distance: 4%/6%/8%/10% (Talent 6.5%/8.5%/10.5%/12.5%) of dealt damage.
    • 600 Distance: 2%/3%/4%/5% (Talent 3.25%/4.25%/5.25%/6.25%) of dealt damage.
  • With Aghanim's Shard icon.png Aghanim's Shard, Dispersion turns into an active ability. The passive component is still present.
    • Creates a Haunt illusion based on its current level on the enemy hero closest to the targeted point.
    • The illusion notes of Haunt apply to Dispersion as well. If Haunt is not learned, the illusion does not spawn.
    • If no enemy dealt damage to Spectre in the last 8 seconds, Dispersion is not castable.
    • Only registers damage dealt by enemy heroes, including illusions, clones and creep-heroes.
    • Does not register damage from invulnerable, hidden or dead heroes.

With great focus of will, Mercurial can sometimes limit the extent of her division.


  • Shadow Step's level is always equal to Haunt's level.
  • Instantly applies the current level of Spectral Dagger on the target, without using a projectile.
  • The illusion notes of Haunt apply to Shadow Step as well.

Haunt icon.png
No Target
Creates a spectral nemesis to attack each enemy hero. At any moment during the duration, Spectre can use Reality to exchange places of a given haunt.
Haunt illusions are uncontrollable, take extra damage, and deal less damage than Spectre herself. They ignore terrain.

  • Haunt illusions are selectable, but uncontrollable.
  • The illusions have unobstructed pathing.
  • The illusions spawn 58 range away from their targets, at a random spot around them.
  • The illusions disappear once their target dies.

Roles: Carry Carry Durable Durable Escape Escape
Complexity: ★★☆
Playstyle: An eternal being of violent energies, Mercurial, the Spectre is irresistibly drawn to conflict. She throws out a Spectral Dagger, creating a shadowy trail to her foes in which she may travel unobstructed. Harm done to Mercurial is partially deflected onto nearby foes, a Dispersion of damage that prolongs her endurance. Even in the most Desolate wilderness, travelers are Haunted by visions of Spectre, seeming to prey on their solitude. But these are no mere illusions. It is said that for one in every five haunted, the apparition becomes Reality, and alongside these unfortunate victims the Spectre appears, bringing with her the destruction that she eternally craves.





  • The name Mercurial most likely comes from the DeviantART account of Kenneth Tan, the person who made the 6.28-6.32 loadscreen.[1][2] 6.28 is also the version in which Spectre got released in DotA.
  • "Mercurial" means "swift, shrewd, and deceitful", which is attributed to the Roman god of thieves, Mercury, as Spectre is an agile and quick Hero. It can also refer to the planet Mercury, since Spectre is an otherworldly entity. Mercurial can also hint towards the element Mercury, often called "quicksilver," which is another reference to Spectre's speed and mobility. When used as an personal adjective, mercurial can mean a personality quick to change and dangerous to both the person receiving and transmitting. Someone quick to forgive and quick to anger would be mercurial, but not someone who holds grudges or holds none. See Mercutio (obviously named) from Romeo and Juliet.
  • Spectre's alternate/fun name "Qwerty-" was given to her for remembering a legendary Dota player Zaven "Qwerty" Terminasov, who died on December 5, 2010.
  • Spectre's voice responses are overlayed with the same track playing backwards, bearing a huge similarity to the Spirit of Vengeance's voice in Warcraft III: Frozen Throne, which is also the voice of Spectre in DotA.
  • Spectre has fewer model animations than any other hero in the game.
