Pulls and manipulates his enemies' positions.
A cunning tactician, the Dark Seer excels at manipulating positions of his enemies. Vacuuming and Punching foes into the attacks of his allies, 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 his Wall of Replica, sowing confusion amongst enemy ranks as an army of duplicates emerge to do battle against their own likenesses.

Dark Seer minimap iconIsh'Kafel, the Dark Seer
▶️ "If your enemy is equal, prepare for him. If greater, elude him. If weaker, crush him."
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.

Normal Punch illusion as they appear to allies and enemies.

  • Grants Dark Seer's next attack True Strike when not on cooldown. The cooldown triggers upon successfully landing an attack on an enemy.
  • Constantly checks the distance Dark Seer moves and calculates the damage, knockback distance, knockback duration, and stun duration accordingly on each server tick.
    • For every 10 distance moved, the damage increases by 4, knockback distance by 2.727, knockback duration by 0.006, and stun duration by 0.012.
  • Teleporting effects (e.g. Blink Dagger icon Blink) may only add up to 600 range to the distance counter, no matter how big the actual teleported distance was.
    • Does not consider upward movement distances.
    • The distance counter never resets, so it is possible to perform multiple full power punches in a row, with cooldown resetting sources.
  • These are the damage, knockback distance, and stun duration values at certain distances moved in the last 3 seconds (before reductions):
    • 0 distance moved: 10 damage, 50 knockback distance, 0.1s knockback duration, 0.2s stun duration.
    • 180 distance moved: 82 damage, 99.09 knockback distance, 0.206s knockback duration, 0.413s stun duration.
    • 360 distance moved: 154 damage, 148.18 knockback distance, 0.313s knockback duration, 0.625s stun duration.
    • 540 distance moved: 226 damage, 197.27 knockback distance, 0.419s knockback duration, 0.838s stun duration.
    • 720 distance moved: 298 damage, 246.36 knockback distance, 0.525s knockback duration, 1.051s stun duration.
    • 900 distance moved: 370 damage, 295.45 knockback distance, 0.632s knockback duration, 1.264s stun duration.
  • Normal Punch first applies the stun, the spell damage, the knockback, then the attack damage.
  • If Wall of Replica icon Wall of Replica is not learned, the illusion deals 80% damage by default.
  • The illusion is spawned 350 range behind the enemy's determined landing position, seconds after Normal Punch was delivered.
    • The illusion can be controlled normally and is initially ordered to attack the punched target.
    • Successive punches can create multiple illusions.
    • The illusion has a
      2 × IllusionLVL bounty.
  • Destroys trees within 100 radius enemies come in contact with during the knockback.
  • The punch particle and sound effects upgrade when the distance counter is at 300, and upgrade again when at 900.
    The invulnerable modifier is responsible for the ability effects upon knocking back an enemy unit.
    • It is only for cosmetic purposes and has no impact on gameplay.

Illusion skin 2

Wall of Replica illusion as they appear to allies and enemies.

  • The values of the wall are set upon cast and do not update upon leveling the ability up after having placed the wall.
  • A wall can only create one illusion per player. There cannot be more than one illusion per player per wall.
    • This means when there are multiple walls up (with multiple casts), every valid enemy unit affected is still limited to one illusion per wall.
    • For Enchant icon Enchanted illusions, the wall still cannot create another illusion until the previous one dies.
    • When the illusion dies, Wall of Replica creates a new illusion of that hero as soon as it comes in range.
  • Upon spawning, the created illusions are visually distinguishable and are automatically ordered to attack the heroes they are based on.
    • Its duration is based on the remaining Wall of Replica duration from which they originate.
    • They have a static 5 Gold and 5XP bounty which does not scale with levels.
  • The illusion spawns 108-distance from the affected enemy hero if the target's collision size is 27, and 72-distance if its collision size is 18.
    • The created illusion appears either north, east, south, or west from the target.
  • The movement speed slow is applied constantly within the wall's area, provided by an aura. The aura lingers for 1 second.
    • The slow of multiple overlapping walls does not stack.
