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

Innate: Illaoi periodically spawns a Prophet of an Elder God 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
Notes
  • Prophet of an Elder God Tentacles do not spawn in the Nexus Obelisk's attack range.
  • They take about 2 seconds to finish their spawn animation.
  • If Illaoi uses Harsh Lesson Harsh Lesson on a target during their spawn animation, the Tentacle won't attack but the SFX of the Tentacle attacking will be heard.
    • If there's a nearby spirit / vessel when this happens, after the Tentacle finishes its spawn animation, its attack against the spirit / vessel will be delayed based on when the target was hit, up to a maximum delay of 1 second.
  • 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 won't disappear after Illaoi stops dancing, and if she issues another dance command, the previous SFX will add on top of the new SFX. They can stack infinitely.

Test of Spirit
TARGET RANGE: 900
TETHER RADIUS: 1700
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, stopping at the first enemy hit. Against champions pulls their Spirit, placing it in front of Illaoi, and Prophet of an Elder God tentacles in range are signalized to attack it. The target is tethered to the Spirit, and True Sight icon revealed while it remains active.

Spirits have the target's current health and last for 10 seconds, reduced by 1 second each time the target damages Illaoi. Illaoi and her allies can attack the Spirit to inflinct a portion of the damage dealt to the tethered champion.

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

Vessel: Prophet of an Elder God Tentacles spawn near them every 5 / 4 / 3 seconds, and nearby Prophet of an Elder God tentacles attack them. Prophet of an Elder God Tentacles can autonomously attack a Vessel / Spirit only once every 10 seconds.

Ability Details
Notes
  • 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 shield 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. Following this the damage is subject to modifiers, such as resistances and amplifiers (e.g. Lord Dominik's Regards item Lord Dominik's Regards) and will be able to exceed the Spirit's current health.
    • True Damage is not affected by these modifiers but 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 The Black Cleaver, Morellonomicon item Morellonomicon, Executioner's Calling item Executioner's Calling, or the healing from Death's Dance item Death's Dance / Hextech Gunblade item 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 Wit's End) although the damage of those effects dealt to the Spirit will be transferred.
    • The Black Cleaver item The Black Cleaver can only apply 1 stack per ability, and will be applied by the transferred damage. Because of this the spirit is unable to stack it.
  • 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.

Ability Details
Notes
  • 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.
  • Illaoi will face the closest enemy champion when she ults, and will spawn tentacles (850 range away from her, unless there's a wall blocking the way making the tentacle spawn on it) based on:
    • The direction she's facing.
    • How many champions she hits.
      • 1+ champions: one tentacle at 90 degrees.
      • 2+ champions: one tentacle at 165 degrees.
      • 3+ champions: one tentacle at 15 degrees.
      • 4+ champions: one tentacle at 230 degrees.
      • 5+ champions: one tentacle at 315 degrees.
  • The animation may get bugged if Illaoi moves immediately after using Leap of Faith.
  • Spell shield will block the ability's damage but will not prevent Prophet of an Elder God Tentacles from spawning.
