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.
Pros / Cons
-his ice blast slows the enemy
-Awesome Ulti with over 2000 Damage!
-I dont find anything ;)
I took these Masteries and Runes because nunu can make lot of damage! (over 2000 with ulti later, and 500 with ice blast).Nunu "can" be played as tank but i dont think that this is good.
