STATIC COOLDOWN: 20 - 12 (based on level)
Prophet of an Elder God

Innate: Illaoi periodically spawns a Prophet of an Elder God.png Tentacle on nearby impassable terrain if none are nearby, which remains on the battlefield until killed or when disabled for 60 seconds.

Tentacles deal 10 - 180 (based on level) (+ 120% AD) physical damage when commanded to attack by her abilities. See Pet Details for more.

Ability Details
Prophet of an Elder God is a summon.

Additional Information:

  • Prophet of an Elder God.png Tentacles do not spawn in the Nexus Obelisk's attack range.
  • If Illaoi uses Harsh Lesson.png Harsh Lesson on a target while a Tentacle is spawning, the SFX of the Tentacle attacking will be heard even if the Tentacle hasn't finished spawning and thus won't attack.
  • If Illaoi dances, awaken tentacles will dance as well.
  • Sometimes when Illaoi dances while a Tentacle is spawning it will result in a weird VFX bug causing the Tentacle to glow.
  • If Illaoi spams the dance command and moves, Tentacles' SFX will keep on adding on top of the previous SFX, infinitely.

Bonus Physical Damage:
3 / 3.5 / 4 / 4.5 / 5% (+ 2% per 100 AD) of target's maximum health

Test of Spirit
COST: 35 / 40 / 45 / 50 / 55 Mana
COOLDOWN: 20 / 18 / 16 / 14 / 12
Test of Spirit

Active: Illaoi unleashes a tentacle in the target direction that stops at the first enemy hit. If the enemy is a champion, the tentacle grabs their Spirit and places it in front of her as well as signaling tentacles in range to attack the Spirit. For the duration, the affected champion is tethered to their spirit and True Sight icon revealed so long as the tether holds.

The Spirit has the target's current health and lasts for 10 seconds, reduced by 1 second each time Illaoi receives damage from the target. During this time, the Spirit can be attacked by Illaoi and her allies, inflicting a portion of the damage it receives upon its tethered champion. This damage doesn't take in account the Spirit's damage modifiers. The reflected damage is done as if the Spirit had the tethered champion's damage modifiers.

Damage Transmission:
25 / 30 / 35 / 40 / 45% (+ 8% per 100 AD)

The tether is severed if the Spirit is killed or when the target moves too far away, Slow icon slowing them by 80% for 1.5 seconds, and marking them as a Vessel for 12 seconds.


Vessel: Vessels spawn a Prophet of an Elder God.png Tentacle every 5 / 4 / 3 seconds as well as cause tentacles they move near to attack them. Tentacles can autonomously attack a Vessel / Spirit only once every 10 seconds.

Ability Details
  • Even though the ability is considered a skill shot, if Illaoi is in a bush and the enemies have no vision on it, they won't be able to see the tentacle leaving the bush until they get hit by it.
  • Spell shields will only prevent your Spirit from being grabbed. Spell shields will not prevent you from becoming a Vessel or prevent tentacles from attacking you, although they can be used to block a tentacle's attack.
  • Redirected damage (the damage dealt after applying the ability's modifier) cannot exceed the Spirit's current health. The redirected damage is still subject to modifiers when inflicted to the target, such as resistances and amplifiers (e.g. Lord Dominik's Regards item.png Lord Dominik's Regards).
    • True Damage will be modified by Test of Spirit's modifier.
  • The amount of damage that will be redirected to the Vessel does not take into account the Spirit's resistances - the redirected damage is only reduced once, by the Vessel's resistances.
    • The damage shown being received by Spirit is not representative of the damage redirected to the Vessel, as the combat text shown adjacent to the Spirit factor the Spirit's resistances - which may be different from the Vessel's.
  • Damage transferred to the target will apply damage-type specific effects such as The Black Cleaver item.png The Black Cleaver, Morellonomicon item.png Morellonomicon, Executioner's Calling item.png Executioner's Calling, or the healing from Death's Dance item.png Death's Dance / Hextech Gunblade item.png Hextech Gunblade, determined by who dealt the damage.
    • It will not trigger on-hit effects or spell effects versus the target (Deathfire Touch mastery 2016.png Deathfire Touch, Wit's End item.png Wit's End) although the damage of those effects dealt to the Spirit will be transferred.
  • Spirits are classified as Decoys, making them targetable as a champion.
  • Even towers, minions, and neutral monsters can attack Spirits.
  • Killing a Spirit rewards you with Gold 25.

Leap of Faith summons a Prophet of an Elder God.png Tentacle for every enemy champion and Test of Spirit.png Spirit hit, which lasts for 8 seconds, during which Harsh Lesson.png Harsh Lesson's cooldown is also reduced to 2 - 1.1 (based on cooldown reduction) seconds. For the duration, all Prophet of an Elder God.png Tentacles awaken by Illaoi (and not by a vessel) are untargetable, will not disable if Illaoi moves too far away, and attack 50% faster.

Ability Details
Leap of Faith is a point-blank area of effect.

Additional Information:

  • Illaoi is immune to being Airborne icon displaced while in her cast animation.
  • Spirits are counted as champions for the purposes of Leap of Faith, so it will summon another Tentacle for a Vessel hit.
  • The animation may get bugged if Illaoi moves immediately after using Leap of Faith.

The Tentacle also automatically attacks the closest target in its range, every 10 seconds (counted after it finishes its first attack), which can be:

On-hit effects Hits through Counter Strike.png Counter Strike and Aegis Protection.png Aegis Protection.
Spell effects Applies spell effects as an area of effect ability.
  • Banshee's Veil item.png Spell shields will block the attack.
  • The Tentacle deals「 50% 」「 5 - 90 (based on level) (+ 60% AD) (+ 0 / 5% / 7.5% / 10% / 12.5% / 15%) 」damage to enemies already struck by another Tentacle within the last 0.5 seconds.



The Tentacle damages all non-structure enemies it hits along its length, healing Illaoi for 5% missing health if it hits at least one enemy champion.


The Tentacle alerts Illaoi whenever it takes damage.


If the Tentacle is too far away from Illaoi or a Vessel.png Vessel, it becomes dormant, reducing itself to 1 health and disappearing after 60 seconds of dormancy. The Tentacle instantly reactivates if Illaoi or a Vessel.png Vessel moves back in range.


The Tentacle enrages for 8 seconds after Leap of Faith.png Leap of Faith has been cast, becoming untargetable and swinging 50% faster.
