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 Jax

Tips to maximize your impact

  1. Start trades with Counter Strike

    Start your trades with Counter Strike (E): you dodge autos and take less area damage, and each dodged auto adds damage to the stunning counterattack.

  2. Look for long trades

    Look for long trades: each consecutive auto increases your attack speed thanks to Relentless Assault (passive).

  3. Ward hop to escape

    To escape, place a ward and jump to it with Leap Strike (Q): it can target any unit or ward, allied or enemy.

  4. Activate your R up close

    Activate Grandmaster-at-Arms (R) up close: it only grants armor and magic resist if it hits a champion, and your bonus hits then land every other auto.

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.
