Ish'kafel, the Dark Seer, is a melee intelligence hero with versatile abilities that allow him to assist allies and greatly change the conditions of combat. His Vacuum in particular affects enemies in a large area and is a powerful crowd-control. It not only disorients and damages enemies, but also pushes them into a small area to follow up with area spells or to trigger other abilities, such as his Wall of Replica ultimate that turns the very power of enemies against them in the form of illusions that replicate their statistics. His other spells focus on buffing allies with speed, or in the case of his Ion Shell, granting an aura that radiates damage onto enemies who venture within it.


Dark Seer Ish'Kafel, the Dark Seer
Play "If your enemy is equal, prepare for him. If greater, elude him. If weaker, crush him."
Lore: Fast when he needs to be, and a cunning strategist, Ish'Kafel the Dark Seer requires no edged weapons to vanquish his enemies, relying instead on the strength of his powerful mind. His talent lies in his ability to maneuver the fight to his advantage. Hailing from a place he calls 'The Land behind the wall,' Dark Seer remains an outsider here—a warrior from a realm beyond the veil of this reality.

Once a great general among his people, and a valiant defender of the god-king Damathryx, Dark Seer’s army was wiped out by a much larger force in the final days of the Great Boundaries War. Facing certain defeat, he made one last desperate act: he led the enemy forces into the maze between the walls. At the last moment, just before capture, he crossed over—then sealed the walls forever in an explosive release of dark energy. When the dust settled, he saw that he had saved his people but found himself blinking at the sun of a different world, with no way to return. Now he is committed to proving his worth as a military strategist, and vows to show that he’s the greatest tactician this strange new world has ever seen.

Does not pierce spell immunity. Play
Vacuum icon.png
Target Area
Dark Seer creates a vacuum over the target area that sucks in enemy units, disrupting them and dealing damage.
Cast Animation: 0.4+0.7
Cast Range: 500
Effect Radius: 250/350/450/550 (Talent 325/425/525/625)
Damage: 40/80/120/160
Pull Duration: 0.5
Cooldown symbol.png 32 (Talent 27.2)
Mana symbol.png 100/130/160/190
Does not pierce spell immunity. Attempts to deal damage if enemy turns spell immune before the pull ends.
Debuff Vacuum: Dispellable with strong dispels.
Ish'Kafel modifies the center of gravity to a place of his choosing.


  • The pull duration always takes 0.5 seconds, no matter how far or close the units are from the center, so the speed varies.
  • Affected units are fully disabled during the pull.
  • The damage is applied upon losing the debuff, so that dispelling it causes it to happen earlier.
  • Can pull units over impassable terrain.
  • Vacuum destroys trees within 275 radius at the targeted point upon cast.

Ion Shell
Not blocked by Linken's Sphere. Partially pierces spell immunity. Play
Ion Shell icon.png
Target Unit
Surrounds the target unit with a bristling shield that damages enemy units in an area around it.
Cast Animation: 0.4+0.7
Cast Range: 600
Damage Radius: 250
Damage per Second: 30/50/70/90 (Talent 180/200/220/240)
Duration: 25
Cooldown symbol.png 9 (Talent 7.65)
Mana symbol.png 100/110/120/130
Partially pierces spell immunity. Can be cast on spell immune allies.
Cannot be cast on spell immune enemies. Shell persists if debuff was placed before spell immunity and when not dispelled.
Buff or Debuff, based on the target's alliance Ion Shell: Dispellable with any dispel.
The Dark Seer slices holes into the 'Land Behind the Wall,' causing prismatic energy to seep forth.


  • The shell can be put on enemy and allied units, damaging only enemy units. The unit with the shell itself is not damaged.
  • Successive casts on the same unit do not stack. Casting it on a unit that already has the Ion Shell on, only refreshes the duration.
  • Deals 3/5/7/9 (Talent 18/20/22/24) damage in 0.1 second intervals, starting 0.1 second after the cast, resulting in 250 damage instances.
  • Can deal up to 750/1250/1750/2250 (Talent 4500/5000/5500/6000) damage to a single unit (before reductions), if it stays in range for the full duration.
  • Affects invisible units that go close to the shell wearer, however, the visual effects do not appear.

Pierces spell immunity. Play
Surge icon.png
Charges a target friendly unit with power, giving it a brief burst of maximum movement speed.
Cast Animation: 0.4+0.57
Cast Range: 600
Radius: 0 (Talent 300)
Haste Speed: 550
Duration: 3/4.5/6/7.5
Cooldown symbol.png 13/12/11/10 (Talent 11.05/10.2/9.35/8.5)
Mana symbol.png 50
Buff Surge: Dispellable with any dispel.
Ish'Kafel once used his speed of mind to navigate the maze between the walls.


  • Applies a haste on the target, meaning it cannot be slowed below the set value.
  • The talent turns Surge into an area-targeted spell, so that it cannot directly target units anymore.

Wall of Replica
Pierces spell immunity. Play
Wall of Replica icon.png
Target Point
Raises a wall of warping light that slows and creates replicas of any enemy hero who crosses it. Enemy replicas serve at the Dark Seer's will. Replicas last until they are destroyed, or until the wall's duration ends.
Cast Animation: 0.4+0.57
Cast Range: 500/900/1300
Number of Walls: 1 (Talent 2)
Wall Length: 1000
Wall Width: 50
Parallel Wall Distance: 600
Movement Speed Slow: 75%
Illusion Damage Dealt: 60%/75%/90% (Upgradable by Aghanim's Scepter. 100%/120%/140%)
Illusion Damage Taken: 400%
Duration: 45
Slow Duration: 0.5/0.75/1
Cooldown symbol.png 100 (Talent 85)
Mana symbol.png 125/250/375
Upgradable by Aghanim's Scepter. Increases the damage dealt by illusions.
The Dark Seer, while unable to return to his natural realm, can channel part of the prismatic wall with powerful strength of mind, sowing confusion amongst enemy ranks.


  • The wall is always created perpendicular to the line between Dark Seer and the targeted point.
  • Only creates illusions of heroes. Does not create them of illusions.
  • Does not create an illusion for each Meepo Meepo clone, only one of them can have a Wall of Replica illusion at a time.
  • When the illusion dies, the wall can create a new one of that hero as soon as it comes in range.
  • Illusions created by Wall of Replica have a static 5 gold and experience bounty which does not scale with levels.
  • Every time the wall creates an illusion, it slows the hero right afterwards.
  • The illusions's duration is based on the remaining duration of the wall from which they originate.
  • The illusion spawns 108 range away from the hero if the hero has a collision size of 24, and 72 if the collision size is 8. It appears either north, east, south or west from the target.
  • Wall of Replica illusions are visually distinguishable for the enemies.
  • When choosing the parallel wall talent, a second wall is placed 600 range behind the first wall, parallel to it.
    • Both walls can affect the same units, so that two wall illusions can exist per hero at a time.

Playstyle: In a final, calculated move, Ish'Kafel led his outnumbered army into a new world, sealing the path behind with a burst of dark energy. A cunning tactician, the Dark Seer manipulates gravity to pull foes into a Vacuum, drawing them into the prismatic thorns of his Ion Shell. Armed only with his intellect, he Surges across the land to survey every point of conflict. At strategic locations Ish'Kafel places a Wall of Replica, sowing confusion amongst enemy ranks as an army of duplicates emerge to do battle against their own likenesses.





  • Dark Seer's response, "Speed is the heart of battle." is an indirect quote of Chinese military strategist Sun Tzu, who said "Quickness is the essence of war."
  • Dark Seer's response, Play "No, I will not calm my beard." is a response to Beastmaster Beastmaster's and Clockwerk Clockwerk's rival hero taunts, both voiced by Sam A. Mowry.
  • Dark Seer's Vacuum's lore is based on the military term, center of gravity, which is a concept developed by Carl Von Clausewitz, a Prussian military theorist, in his work On War.
