Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This is a build that i have put together that comes out for a strong ulti and ice blast late game.
Early game-I prefer to take he solo lane to get a head start on lvls and gold for your items.Harass the champions with ice blast and go for as many ganks as you can to stack your soulstealer up.
Mid- Mid game is when you will start to see if you will win or lose.Nunu's aoes are perfect for team battles use your ulti to get the whole team down then chase them off.This will produce good team pushes.
Late-Late game is when team battles depend on your AoE use it correctly and you will have no problem winning.
Well this is my first build.Enjoy and comment and rate please.
