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 the build I will be using on lvl 30. The spells are focused on mana and teleportation, the runes on attack speed and armor penetration and the items on damage, crit.chance and attack speed.
This build is not regular for this character but this is how I always play as it grants me a lot of victories. The build I use now is like this but with regular runes.
