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.
If you dont have the comlete rune build start with doran ring that gives some health at beggining. Start at mid lane and cast flash frost to damage your enemy as many time as you can if you have doran ring get a mana potion and a health potion for the start. Try to stick together with your teammates after began the gank phase. Do not forget you have 2x revive first you revive with 40%hp then egg stage. This makes you hard to kill. if your team assist you you will be legendary. Nearly 6k mana means you can cast your ultimate as long as you can but dont forget you are a support and your AP is too low to kill a tank or a high health enemy. Try to trap your enemies cause your slow exrtemely hard and they cant leave it as fast as they hope. Use OFTEN frost bite frozen hearth gives u 25%cd reduction this means is has only 3sec cooldown!!! If you like to play more safety you should use Greater Seal of Fortitude 9x times this gives you extra 50hp at start.
