Fighting Illaoi is like fighting a Boss.
Today I picked Nasus and though that I'll be facing many Illaoi's in the top Lane. As a Nasus player I though Tentacles = Free Stacks. During laning phase I was able to dodge all her attacks and was laughing at her. But when I walked to kill one of her Tentacle she spirit hooked me and start beating my Spirit. I was like WTF she does soo much damage but then I realized I was in trouble. The screen turned foggy greenish and tentacle's spawned all around me to smash me, all I could scream was I'm sorry I didn't meant to stack on you guys while I was running for my life.
But as time passed I became that late game monster with the Crit Masteries and crit build Nasus (S6 Meta if you don't go Crit then you are doing something wrong) I TP and ghosted to END my early game terror that was Illaoi.
I screamed, DIE YOU TENTACLE FREAK!
