Innate
Periodically, Illaoi spawns a Tentacle on the nearest terrain, if no other Tentacle is around it.
Tentacles fully spawn after a 2 second delay and are untargetable in the meantime.
Tentacles are commanded to attack by Illaoi's abilities, dealing (110% AD) (40% AP) physical damage to all enemies struck, increased by .
Each enemy individually reduces the slam damage by 50% for every slam they were hit by in the last 0.66 seconds, capped at 75% less damage.
Each Tentacle also heals Illaoi for 5% of her missing health if it hits at least one enemy champion.
Q
Passive
Tentacle slam damage is increased.
Active
Illaoi slams down a Tentacle in the target direction.
Illaoi reveals herself during the cast if there is an enemy champion nearby.
W
Active
Illaoi empowers her next basic attack within 6 seconds to gain 225 bonus range and cause her to leap to the target's location if they are beyond her normal basic attack range.
The attack deals additional 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 additional damage can also be applied against turrets.
Harsh Lesson resets Illaoi's basic attack timer.
Harsh Lesson can be activated during Illaoi's other abilities.
E
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 are a champion.
The target is tethered to the Spirit for 7 seconds, revealing them in addition to granting sight of the area around them while the tether remains.
The Spirit spawns with the target's current health, armor and magic resistance, and redirects a portion of the pre-mitigation damage received to the tethered champion.
When the Spirit is killed or the target leaves tether range, the tether is severed, marking the target as a Vessel for 4 seconds and 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 seconds.
Enemies made a Vessel continuously spawn a Tentacle near themselves, when possible.
Tentacles can spawn 300 units closer to each other than when spawned by Illaoi.
Illaoi is unable to act while firing the projectile and while the target's Spirit is being pulled.
She also reveals herself while firing the projectile if there is an enemy champion nearby.
Vessels can dispel their mark by scoring a takedown against Illaoi.
Test of Spirit cannot be cast again until the Spirit dies.
When the Spirit is killed or the target leaves tether range, they are marked as a Vessel for 4 seconds and slowed by 80% for 1.5 seconds.
Tentacles autonomously attack the closest Vessel or Spirit, prioritizing the Spirit, once every seconds.
Vessels continuously spawn a Tentacle near themselves when possible. Tentacles can spawn 300 units closer to each other than when spawned by Illaoi.
Vessels can dispel their mark by scoring a takedown against Illaoi.
R
Active
Illaoi gains 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).
For the duration, Harsh Lesson's cooldown is halved, all Tentacles awakened by Illaoi are untargetable, will not show their hitboxes, nor go dormant, and will take 0.5 seconds to make an attack; however they will then incur a lockout of 0.5 seconds before being able to start a new attack.
This does not affect the Tentacle attack from Tentacle Smash.
Summoned unit on this kit. Hover underlined numbers for every level.
