Just an Illaoi E rework idea
No longer a skillshot projectile but a skillshot similar to new Rengar Q where she kicks somebody directly in the direction of the cursor(melee range). If she hits a champion they are knocked back 700 range and get their spirit pulled out. They gain 80% movespeed when running towards their spirit
Spirit is untargettable and Illaoi must stay within 200 range of the spirit or her E cancels. During this time the opponent spawns 2 tentacles between them and the spirit with the tentacles slamming towards them. If they get within 200 units of the spirit they win the spirit back and the cooldown on Illaoi E starts back up. They get a speed boost for a short duration(0.5 seconds) of 100% after claiming their spirit and the tentacles despawn.
Until the spirit is reclaimed and Illaoi stands near it, they will continue to spawn a tentacle every 3 seconds to slam towards them. Every 3 seconds they don't claim it they spawn tentacles even faster and they lose movement speed after 5 seconds of initial pull when running away. If they do not reclaim the spirit after 10 seconds then they die.
Just a random rework idea i had
