Illaoi's abilities

Passive, spells and ultimate

Prophet of an Elder God (P)

Illaoi and the Vessels she creates spawn Tentacles on nearby impassible terrain. Tentacles swing at spirits, Vessels, and victims of Illaoi's Harsh lesson. Tentacles deal physical damage to enemies hit, and will heal Illaoi if they damage a champion.

Playing as Mordekaiser

Tips to maximize your impact

  1. Hit a lone enemy with your Q

    Aim Obliterate (Q) at a lone enemy: if only one enemy is hit, the damage increases.

  2. Activate your passive, then stay close

    Hit champions or monsters three times, then stay close: Darkness Rise (passive) then surrounds you with a damage aura and gives you move speed.

  3. Pull them into your Q

    Pull your targets into the Obliterate (Q) zone with Death's Grasp (E): each spell that hits also counts toward Darkness Rise (passive).

  4. Tank with Indestructible

    Cast Indestructible (W) when you're taking damage: it turns stored damage into a shield, and a recast converts part of it into health.

  5. Isolate the carry in your R

    Cast Realm of Death (R) on their carry, or their jungler near an objective: you isolate them with you, steal part of their stats, and keep them if you kill them.

Playing against Illaoi

How to counter and exploit weaknesses

  1. Dodge her E

    Dodge Test of Spirit (E): if it hits, you take part of the damage dealt to your spirit, and if the spirit dies, you're slowed and marked for her tentacles.

  2. Hit her if she pulls your spirit

    If Test of Spirit (E) pulls out your spirit, attack Illaoi instead of running: damaging her shortens the spirit, and moving too far from it marks you for her tentacles.

  3. Pull her away from walls

    Take your trades away from walls: Prophet of an Elder God (passive) spawns her tentacles on nearby terrain, and each tentacle that hits you heals her.

  4. Ask for ganks

    Ask for ganks: Harsh Lesson (W) only makes her leap toward an enemy, so she has no dash to escape, and no stun.

  5. Back off during her ult

    Don't fight during Leap of Faith (R): each champion hit spawns a tentacle, and while it lasts, they're untargetable and slam faster.
