Ice Typhoon: If for example Fizz steps into Ice Typhon but immediately uses his E, he still gains a debuff over time that deals magic damage.

Chilling Area: It's kind of like a blast, and every enemy hit gets a DoT debuff. Riuzak designed this ability and when I put it on the notepad to change it I didn't really look at the root values, which are indeed op. That was a fail on my part, I will definitely tune them down.

Lethal Frost: I think I should tune down the passive effect as you said. I don't reduce the cooldown so it doesn't become a spammable burst, and the root is there to make it feel like the enemy is frozen, but come to think of it, as Weirdbob95 said, I should make the E a slow instead.

Arcane Imprisonment: I like this ability really much and I don't think of changing it to another one, suits him lorewise and powerwise. I am thinking of a channeling effect to nerf the ability.

Thanks for the criticism, you are one of the best ones to comment on my Khrax champion, I'm glad you commented on my Sla'arth one! :)
