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.
I'm French so it's hard to write a description but this build is very very cool! Lots of power and life and with your egg you are safe for successful 1vs2. For the early games go in the middle! Wait your level 6 for the ultimate combo (Flash Frost - Glacial Storm - Frostbite - Crystallize to keep your enemy inside your ultimate)and you have a KILL =D
Repeat this step several times with your cooldown:) Go kill the golem blue as often as possible to have a lot of mana.
