As you can see it is a FULL damage build. No escapes, but it can work wonders as I have before wiped the whole enemy team alone. (Yes the stars were aligned and that was right before the Leoric patch, but it is possible.) Really focuses on getting a bit closer that a Jaina normally would to lay down the Elemental and get the double Cone of Cold Northern Exposure stacks on the enemy. Follow that up with the Blizzard and double Ice Lance. With Icy Veins activated you can almost instantly use Cone of Cold and Ice Lance a second, sometimes third time. Anyone without a spell shield will die, and even those with will be feeling the pain too.

Now yes. You have NO escapes. If you thought positioning Jaina was hard in the first place, than this is not the build for you. Your position is even more important here. One step too close and you'll be dropped in seconds. One step too far away and your Cone of Cold won't hit. Your power spike really hits at 20 when you get the Wintermute. The synergy with Icy Veins and Wintermute can really dish out insane damage numbers in seconds. So if you're ever in a pinch it's just a race as to who can kill who first.
