I'm almost mastery 4 with Illaoi already, here are some ways to counter her. ^_^

I'm planning on having the most mastery points on illaoi in NA, it may take a while, and I'm probably quite far behind the top person already, but I think I can do it. Anyways, here are some ways to counter her.

In lane:

I don't recommend ganking her, it will very likely turn into a double kill for her. Do not fight her in her zone, or you will die.

Try to just stay behind minions and farm from your turret, she can't do much to you under your turret. Even if she pulls your spirit, she will have a hard time doing much to it.

If she DOES grab your spirit, try to fight her if you think you can. the more you damage her, the less time he has to break your spirit.

HOWEVER, also be aware that she may be trying to bait you into an ult my grabbing your spirit, so going all in against her is a poor idea, she is made to punish people who try to go all in.

Personally, I feel she may be a little bit too oppressive in lane, but despite that, she definitely does have strong weaknesses.

Teamfights and dueling:

Healing reduction, health shred, and CC are very dangerous to her.

Do NOT clump up while she is around, or she can single handedly 1v5 your entire team, if you give her a chance to set up her ult you WILL die.

She has no CC, champions like Katarina and anybody with health shred will completely destroy her.

She's not usually as tanky as she looks, burst damage can really fuck her up and prevent her from taking advantage of her healing.

Also, her only way to get to you is to walk to you. She CAN get quite fast with boots of swiftness and Dead Man's. But she still has to walk to you, so if you hit her with CC, you can stop her from dunking your team.
