So just something I noticed about your skill sequence. You have 6 ranks of Flash Frost and only 4 ranks of ice wall. I am thinking you should fix that.

hmmm alright haha makes sense to me thanks for clearing that up.

This is false. Flash Frost and Frostbite actually deal about the same amount of damage. At equivalent skill lvls Flash Frost will at most deal 10 more damage than Frostbite, and since they both scale at the same amount AP wise, they will basically do the same amount of damage. Flash Frost just costs more mana, has a longer CD, a longer range, and can stun.

yeah i would say more damage does come from frostbite if you had a hard time getting a double hit from flash frost, but if you're able to land the double hit which is allowing flash frost to pass through the rival champion then pressing Q you actually obtain more damage. Plus i get flash frost first just for the stun because i find it more useful in the beginning :D

Looks well done but just thinking, doesn't more damage come from Frostbite than Flash Frost?
Other than that, great build! :)
