Illaoi rework idea.
Illaoi is strong in chaotic, full blown 5v5 teamfights or any fight where she gets 3 tentacles or more. She is susceptible to kiting which is fine but she has no real way of reaching enemies(outside of E).
Her "moments of power" are super conditional. You either need to land your ult on multiple enemies to get tons of tentacles or you get screwed over. Any team with a brain makes Illaoi useless.
In this rework I thought about, I want to make her laning more tolerable while making her late game strength feel and become more reliable(she falls off late game if not fed).
New passive, Prophet of an Elder God: Illaoi carries an idol which channels Tentacle Hentai Monster(I forgot the name). While Illaoi is alive, she has 1 tentacle attached to her idol, lying dormant but becomes active when used with her abilities. When the tentacle is in an active state(lasts 3 seconds) Illaoi will be able to cast her W.
Q: Same as before just now when you use this ability it activates tentacle by putting it into an active state. The damage would probably be nerfed early but make it stronger later.
New W, Harsh Lesson: This move may only be used when the tentacle is in an active state. When Illaoi uses this technique, for the next 3 seconds she gains 30% movespeed while moving towards an enemy champion. When she is within 550 range of an enemy champion, she may click on the enemy champion which will cause the tentacle to throw towards the enemy champion and make a tether. Over 2.5 seconds the tentacle contricts the enemy, slowing them increasingly to 50-90%. After 2.5 seconds if the enemy did not break the tether they will be CC'd in place for 1-2 seconds. The tether is either broken by running out of range or destroying the tentacle. 2 autos kill it for melees, 3 for ranged.
New E, Test of Spirit: same as before in pulling the enemy spirit and fighting for it but now the spirit has 10 bars instead of a health bar. If Illaoi and her team hit the spirit 10 times he/she is a vessel. If Illaoi is hit 10 times the spirit returns. Vessels have tentacles sprout from them every 10 seconds, doing nothing for 2 seconds. If the vessel doesn't destroy the tentacle then they take the same damage as from her W but are CC'd without the slow. The tentacle takes 2 autos from melees to destroy, 3 for ranged. Each of the 10 bars deals 2/2.5/3/3.5/4% current health damage, increasing by 1% to each bar for every 100 total AD Illaoi has. Vessels last for 1 minute or 3 tentacles destroyed. Killing her W tentacle counts.
New R: Leap of Faith: Illaoi leaps to target location(think Malphite ult) and summons 2/4/6 tentacles as long as an enemy champion is there. The target location she lands in creates a circle to show the zone where Illaoi is powerful(think Skarner spires but way smaller). While Illaoi is in the circle, the tentacles will non-stop slap any enemy champion in the circle. These tentacles deal 50% of her normal tentacle damage and heal her for 2% missing health instead of 5%. If Illaoi leaves the circle or if there are no enemy champions the tentacles do nothing. Lasts 5 seconds.
Sorry for the wordiness and if it seems op, kinda like Illaoi and want her to be useful outside of lane.
