Illaoi is a champion in League of Legends.[1]



Prophet of an Elder God

Illaoi Prophet of an Elder God.png

Innate: Periodically, Illaoi spawns a Tentacle on the nearest terrain perpendicular to her location, if no other Tentacles are already nearby it. Tentacles fully spawn after a 2 second delay and are Fizz Playful.png untargetable in the meantime.

Tentacles deal 10 − 180 (based on level) (+ 120% AD) (+ 40% AP) physical damage to all enemies struck when commanded to attack by her abilities. Each Tentacle also Heal power icon.png heals Illaoi for 5% of her missing health if it hits at least one enemy Champion icon.png champion. See Pet Details for more details.

  • Illaoi cannot spawn Tentacles on ally invulnerable Turret icon.png structures, in addition to neither her nor the Vessel being able to spawn them in Nexus Obelisk's attack range.
  • Terrain also includes player-made terrain and terrain that is passable by a team but not by the other (e.g. base gates).
  • The Tentacle will continue its spawn animation and be able to start an attack, after the animation ends, even if Illaoi or a Vessel are not nearby.
  • If Illaoi uses Harsh Lesson Harsh Lesson during Tentacles' spawn animation, they won't attack but the SFX of the attack will still be heard.
    • When this happens, the Tentacle's next attack after spawning will be delayed, as if the tentacle was performing an invisible attack.
    • After the tentacle spawns, there's a 0.25 second delay during which they may only be commanded to attack by a Harsh Lesson Harsh Lesson. If followed by a Test of Spirit Test of Spirit command, this attack will be slightly delayed, as per above.


Tentacle Smash

Passive: Tentacle damage is increased.

Damage Increase:
10 / 15 / 20 / 25 / 30%
Illaoi Tentacle Smash.png

Active: Illaoi slams down a Tentacle in the target direction, dealing physical damage.

  • This ability will cast from wherever the caster is at the end of the cast time.
    • Tentacle Smash's hitbox is fixed in front of Illaoi, while the indicator on the ground is fixed to the targeted direction.
  • If Illaoi is not Sight icon.png visible, the slam will be seen but it will not be heard.

    Harsh Lesson

    Illaoi Harsh Lesson.png

    Active: Illaoi's next basic attack within 6 seconds gains Range icon.png 225 bonus range and causes her to Dash.png leap to the target's location if they're beyond her normal basic attack range.

    The attack deals bonus physical damage, with a minimum threshold, and capped at 300 against non-champions, and commands all Tentacles in range to attack the target. The minimum bonus damage can also be applied against Turret icon.png turrets.

    Bonus Physical Damage:
    3 / 3.5 / 4 / 4.5 / 5% (+ 2% per 100 AD) of target's maximum health
    Minimum Physical Damage:
    20 / 30 / 40 / 50 / 60

    Harsh Lesson Fiora Bladework.png resets Illaoi's basic attack timer.

    Harsh Lesson can be activated during Illaoi's other abilities, other than while pulling pulling a Spirit.

    • The bonus damage doesn't apply Life steal icon.png life steal but it does apply Spell vamp icon.png spell vamp.
      • 𝐏𝐄𝐍𝐃𝐈𝐍𝐆 𝐅𝐎𝐑 𝐓𝐄𝐒𝐓 : Omnivamp
    • Harsh Lesson is made of two different abilities which are decided by Illaoi's range to the target, being either Melee role.png melee or within Dash.png dash range.
    • The close range ability:
      • Has an Vi Relentless Force 2.png uncancelable windup.
      • Can be used while Grounded icon.png grounded or Root icon.png rooted. If Illaoi attack commands and then casts Harsh Lesson, she is able to use the close range version within its dash range.
      • Starting the attack before triggering Guardian Angel's Guardian Angel's passive and hitting while she's in it will not cause the Tentacles to slam.
      • The attack will still hit if the target becomes Fizz Playful.png untargetable, but will not if it Death.png dies.
      • Does trigger Hail of Blades Hail of Blades.
      • Triggers Energized Energized effects on-hit.
      • If the empowered attack duration ends during the attack animation, the attack won't be empowered.
    • The dash range ability:
      • Does not have an uncancelable windup, meaning effects that can interrupt the dash will cancel the attack and put the ability on cooldown.
      • Can be cast but cannot be used while Grounded icon.png grounded or Root icon.png rooted because Illaoi loses the Range icon.png bonus attack range.
      • The attack will not hit if the target becomes Fizz Playful.png untargetable, but does hit if it Death.png dies.
      • Does not trigger Hail of Blades Hail of Blades.
      • Triggers Energized Energized effects during the jump.
      • Having enough attack speed will perform an unusual dunk.
      • Having increased size will increase the range of her Harsh Lesson but the indicator range will not change.
      • If the empowered attack duration ends during the dash, the buff will linger until the attack has finished.
    • Parrying the attack (Jax Counter Strike.png dodge, Shen Spirit's Refuge.png block, Blind icon.png blind) will not trigger Tentacle Tentacle slams, with the exception of:
      • Shen Spirit's Refuge.png Block when using a close range Harsh Lesson.
      • Blind icon.png Blind when using a dash range Harsh Lesson.
    • If the target dies at the instant Harsh Lesson is about to hit the target, the attack will hit, be consumed, but will not make the Tentacles slam.
    • The Tentacle attacking because of Harsh Lesson is considered to be of the same cast instance, and thus will not grant additional stacks of Conqueror Conqueror, Electrocute Electrocute, Phase Rush Phase Rush and Tribute.
    • Harsh Lesson's bonus damage applies before Blade of the Ruined King's Blade of the Ruined King's damage.
    • Harsh Lesson triggers Bone Plating Bone Plating and one of its plates with the same attack.
    • Attack moving while charging Hexflash Hexflash will delay the attack.


    Test of Spirit

    Illaoi Test of Spirit.png

    Active: Illaoi launches a tendril in the target direction that stops at the first enemy hit, pulling their Spirit out in front of Illaoi over 0.75 seconds if they're a Champion icon.png champion. The target is Karma Focused Resolve.png tethered to the Spirit for 7 seconds, True Sight icon.png revealing them in addition to granting Sight icon.png sight of the area around them while the tether remains.

    The Spirit spawns with the target's Health icon.png current health, Armor icon.png armor and Magic resistance icon.png magic resist, and redirects a portion of the pre-mitigation damage received to the tethered champion.

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

    When the Spirit is killed or the target leaves tether range, the tether is severed, marking the target as a Vessel for 10 seconds and Slow icon.png slowing them by 80% for 1.5 seconds once the tether returns back to them. Each Tentacle autonomously attacks the closest Vessel or Spirit, prioritizing the latter, once every 5.5 / 4.5 / 3.5 (based on level) seconds.

    Illaoi Vessel.png

    Enemies made a Vessel also spawn a Tentacle near themselves every 5 / 4 / 3 (based on level) seconds. Tentacles can spawn 250 units closer to each other than when spawned by Illaoi.

    Illaoi is Lockout icon 2.png unable to act while firing the projectile and while the target's Spirit is being pulled.

    Illaoi cannot cast Test of Spirit again until the Spirit dies.

    Vessels can dispel the Malzahar Malefic Visions.png debuff by scoring a Damage rating.png takedown against Illaoi.

       "Take back your spirit."

    • Spirits are classified as Shaco Command- Hallucinate.png clones:
      • Spirits can only be fully targeted by Illaoi's team and neutral monsters. The Spirit's allies cannot manually select it as a valid target for spells and abilities, but they can still do so with automatically targetted effects.
      • Spirits take 50% damage from turrets and do not cause turrets to Warm Up Warm Up their attacks.
      • Spirits cannot be Heal power icon.png healed nor Hybrid resistances icon.png shielded (Summon Aery Summon Aery excluded).
      • The Spirit levels up when the Vessel does. Doing so will increase the Spirit's health, armor, and magic resist, and additionally extend its lifetime by 1 second.
    • The Spirit is Fizz Playful.png untargetable while it is being pulled, and spawns with the tethered champion's default model and size.
      • The untargetability is sometimes 0.25 seconds longer, causing Tentacles to attack in delay and allowing Illaoi to cast Leap of Faith Leap of Faith without it targeting the Spirit.
    • Redirected damage is calculated by taking the pre-mitigation damage against the Spirit, applying Test of Spirit's damage modifier, and then capping it to the Spirit's current health. This damage will then be affected by damage modifiers (resistances and other effects) of the Vessel.
      • This order of operations allows Test of Spirit to deal more or less percentage of the Vessel's health than would be expected:
        1. Because the Spirit's modifiers can be different from the Vessel's, and the damage being pre-mitigated, allowing the Spirit to have higher or lower effective health, respectively increasing or decreasing the maximum achievable damage from killing it.
        2. Because the cap is supposed to block excess damage over the Spirit's current health, which does not reliably do so or does too well, depending on whether the Spirit's damage modifier is higher than Test of Spirit's or not, respectively. This causes an increasing difference of damage when the pre-mitigated damage is between Spirit current health ÷ Spiritmod and Spirit current health ÷ Emod.
          • To fix this case, pre-mitigated damage would need to be capped at the amount that kills the Spirit, and only then have Test of Spirit's damage modifier apply.
      • Illaoi needs 937.5 / 875 / 812.5 / 750 / 687.5 total AD to reach 100% redirected damage. As per above, the damage is still dependent on the Spirit's and Vessel's damage modifiers and may not always be able to deal 100% of the target's current health as total redirected damage.
    • Sivir Spell Shield.png Spell shields may only prevent the initial spirit grab and the slow upon becoming a Vessel. Spell shields will not prevent becoming a Vessel or Tentacles from attacking.
    • The tendril can be blocked by abilities such as Yasuo's Yasuo's Wind Wall Wind Wall, but the returning tether slow cannot, even if it can otherwise be Bullet strikethrough.png destroyed by effects that can do so (i.e Fizz Playful.png untargetability).
      • The tether slow will not be fired if the target is already Fizz Playful.png untargetable when the Spirit dies.
    • The spirit pull is not considered a Stun icon.png crowd control effect and will not be blocked by Cc-immune icon.png crowd control immunity, with the exception of Morgana's Morgana's Black Shield Black Shield.(bug)
    • If the target becomes a Vessel within range of a dormant Tentacle, that Tentacle will skip its first attack.
    • The projectile tentacle model is linked to Illaoi's model animation and size. However gameplay wise it is not, thus the actual hitbox being different than the position, width and length of the visible model.
      • The model will stop mid-air / vanish if Illaoi goes into Stasis icon.png stasis, Sleep icon.png sleep or Airborne icon.png airborne, however the actual hitbox will continue its trajectory unseen. The projectile is also not seen by enemies if Illaoi is not Sight icon.png visible, but it will be heard if the tentacle passes through their vision.
    • This ability will cast from wherever the caster is at the end of the cast time.
      • And will fire towards the same pointed location.
    • Grabbing the Spirit of a champion before it goes into Revival icon.png resurrection via Chronoshift Chronoshift or Guardian Angel Guardian Angel will spawn the Spirit with 0 health, making it Taric Cosmic Radiance.png invulnerable.
      • The same does not happen with other resurrection effects (i.e Karthus' Karthus' Death Defied Death Defied) since they leave the champion with more than 0 health.
    • Grabbing the Spirit of a champion with Flow resource.png Flow or Fury resource.png Ferocity will make the Spirit's lifetime (the white bar below the lifebar) disappear.
    • Grabbing the Spirit of an Oathsworn Oathsworn, or of a champion that is Twitch Ambush 2.png camouflaged while they are being revealed by a Control Ward Control Ward, will make the Spirit invisible.
    • Only Illaoi can see who's been Vesseled, with their model covered in watery effects. The Vessel itself will instead have its screen covered in watery effects.
      • Neither Illaoi can see the watery effects on Kayn Kayn if he is turned into a Vessel while he's inside Umbral Trespass Umbral Trespass.
    • The Vessel status effect is a debuff that doesn't persist through death.
    • If the enemy champion is Revival icon.png resurrecting when the conditions for becoming a Vessel are met, then they will not revive as a Vessel.
    • Runes consider the Spirit as a champion for their effects and stat-tracking.
      • Predator Predator only reflects double bonus damage, not taking into account actual damage done to the Spirit (e.g if Predator Predator would deal 60 bonus damage, what would get reflected is 120 damage).
    • Transferred damage will apply on-damage effects, such as Black Cleaver Black Cleaver, Morellonomicon Morellonomicon, Executioner's Calling Executioner's Calling, Riftmaker Riftmaker, Aspect of the Dragon Aspect of the Dragon burn damage.
      • Redirected damage always counts as single target for the purpose of Omnivamp colored icon.png Omnivamp.
      • The Spirit will also redirect the bonus damage dealt by Riftmaker and Aspect of the Dragon, effectively double diping their damage to the Vessel. In particular, Riftmaker also further increases its own redirected damage, granting an additional 0.81% bonus damage at full stacks, for a total of 18.81%.
      • Transferred damage will not doubly apply on-hit or on-spell effects versus the target (e.g. Liandry's Anguish Liandry's Anguish, Phase Rush Phase Rush stacks). These effects are only applied versus the Spirit.
      • Attacking the Vessel and its Spirit simultaneously will only apply one stack of Black Cleaver Black Cleaver to the Vessel.
    • Once the Spirit vanishes, whether Death.png killed or not, it will trigger specific Damage rating.png takedown effects and grant Illaoi 1 creep score in-game (not included in the post-game counter).
    • The Spirit is immune to Stasis icon.png stasis (i.e. Bard's Bard's Tempered Fate Tempered Fate).
    • Fiora's Fiora's Riposte Riposte can be used to prevent becoming a Vessel if used before the Spirit is killed or while leaving the tether's range.
    • Sion's Sion's Spirit cannot be spawned during Glory in Death Glory in Death. Spirits created before Sion's Zombie icon.png zombie state will remain active.
    • If the target that had its Spirit pulled from them is taken into the Realm of Death Realm of Death, the tether will break, but they will not be made into a Vessel.
    • The following table refers for interactions while Illaoi is firing the projectile and while the target's Spirit is being pulled:

    Leap of Faith

    Illaoi Leap of Faith.png

    Active: Illaoi gains Unstoppable icon.png displacement immunity and leaps into the air for the cast time. She then slams her idol into the ground, dealing physical damage to nearby enemies. For each enemy champion hit, a Tentacle is summoned for 8 seconds (up to a maximum of 6 summons).

    Physical Damage:
    150 / 250 / 350 (+ 50% bonus AD)

    For the duration, Harsh Lesson's Harsh Lesson's Cooldown reduction icon.png cooldown is halved, all Tentacles awakened by Illaoi are Fizz Playful.png untargetable, will not show their hitboxes, nor go dormant, and will take half the amount of time to make an attack.

       "There are kind and gentle gods. Mine isn't one of those."

    • This ability will cast from wherever the caster is at the end of the cast time.
    • Illaoi spawns the Tentacle Tentacle 725 range away from her, unless there's a natural wall blocking the way making the Tentacle spawn on it, based on:
      • The direction she's facing.
        • She will always face at the nearest Sight icon.png visible enemy champion, in Leap of Faith's range, the instant she leaps.
        • If there's no enemy champion nearby, she faces in the direction of the cursor.
        • Flashing Flashing mid-animation will change her facing direction to where the cursor is pointed, regardless of the nearest enemy champion.
      • How many champions she hits.
        • 1+ champions: one Tentacle Tentacle at 0 degrees. (in front of Illaoi)
        • 2+ champions: one Tentacle Tentacle at 60 degrees.
        • 3+ champions: one Tentacle Tentacle at 300 degrees.
        • 4+ champions: one Tentacle Tentacle at 120 degrees.
        • 5+ champions: one Tentacle Tentacle at 240 degrees.
        • 6+ champions: one Tentacle Tentacle at 180 degrees.
      • If there are no walls nearby, spawning the last Tentacle Tentacle will form a perfect hexagon.
    • Sivir Spell Shield.png Spell shields will block the ability's damage but will not prevent Tentacles from spawning.
    • If Illaoi Death.png dies within 0.25 seconds of dropping down, she will still spawn Tentacles, but they will not be buffed.
    • If Illaoi is near a Tentacle that is about to spawn, it will spawn buffed by Leap of Faith even if Illaoi is no longer nearby.
    • Using Harsh Lesson Harsh Lesson after Illaoi drops down will command Tentacles to instantly attack, regardless if they were already attacking. Their old attack will keep on going and will hit while the second attack is on its animation attack.
      • This may cause the second slam of the same tentacle to hit too fast and get its damage reduced, which is not otherwise possible.
    • Using Harsh Lesson Harsh Lesson an instant before Leap of Faith's buff finishes will delay the Tentacle's attack.


    Control type The Tentacle Tentacle is commanded to attack each time a target in its range gets hit by Harsh Lesson Harsh Lesson.

    The Tentacle is also able to periodically automatically attack the closest Spirit Spirit or Vessel in its range.

    Its attacks get queued up if it receives more than one attack command. The queued attacks will always have 1 attack speed, even if affected by Leap of Faith's Leap of Faith's buff.

    If a Tentacle is killed while attacking, the Tentacle will first finish its attack and then die, without being able to queue up other commands.

    Tentacles can receive attack commands 0.25 seconds after dying, and are able to queue up other commands during the timeframe.

    Tentacles will only start attacks against targets whose Range center.png center is inside the slam area, but they will also hit targets whose center is further away if their Range model.png edge is inside the area.

    Target type Ward (can be teleported teleported to).
    On-hit effects Hits through Counter Strike Counter Strike and Spirit's Refuge Spirit's Refuge.
    Spell effects Applies spell effects as Katarina Death Lotus.png area damage.

    Tentacles that hit the same target within 0.5 seconds of each other deal 50% less damage than the previous Tentacle, up to a cap of 75% less damage than the first.

    A single Sivir Spell Shield.png spell shield can block all tentacle attacks that hit at the same time.



    The Tentacle damages all non-structure enemies it hits along its length, Heal power icon.png healing Illaoi for 5% of her missing health if it hits one or more enemy champions. Healing Multiple stacking icon.png stacks multiplicatively if more Tentacles attack at the same time, calculated by this formula: (maximum health − current health) × (1 − 0.95n), with 'n' the number of Tentacle hits.


    The Tentacle alerts Illaoi when it Death.png dies.


    The Tentacle remains awakened if Illaoi or a Vessel are within 2000 range and not Death.png dead. If none is nearby, the Tentacle becomes dormant, disabling its ability to start attacks and disappearing after 30 seconds of dormancy. The Tentacle instantly reactivates if Illaoi or a Vessel move back in range.


    The Tentacle enrages for 8 seconds after Leap of Faith Leap of Faith has been cast, becoming Fizz Playful.png untargetable, unable to show its hitbox, unable to go dormant and taking half the amount of time to make an attack.


    All Tentacles around 1000 range of an enemy champion are Sight icon.png revealed through the fog of war.
    When about to slam slam it Sight icon.png reveals the targeted spot to allies.
    The Tentacle grants Sight icon.png sight of nearby Control Wards Control Wards.


    If Illaoi is in a different dimension than her Tentacles (i.e Realm of Death Realm of Death), her Tentacles will continue to target units in their dimension only, but the area of damage will instead be dealt in Illaoi's dimension.
