Illaoi

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 9 – 180 (based on level) (+ 110% AD) (+ 40% AP) physical damage to all enemies struck, increased by 0% – 30% (based on Tentacle Smash's rank).
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.

Passive: Tentacle 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.

Active: Illaoi empowers her next basic attack within 6 seconds to have an uncancellable windup, 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.

If the leap is interrupted, the ability is cancelled and put on cooldown.

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 resist, and echoes a portion of the pre-mitigation damage received to the tethered champion, with the last hits before it dies potentially echoing reduced damage.

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 4.5/4/3.5 (based on level) 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.

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.
