The build on mobalytics is pretty good. I think someone may have linked it earlier. You have options as far as skills you get to decide whether you want more damage using something like light spear or chain lightning but I feel better just taking frozen armor for the defense and stuff. You will do ridiculous damage before your glyphs are even maxed out so.

I forgot about the new ring. Definitely pick the build that incorporates tals ring and wreck everything in the game.
