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.
Just for fun
So this is just a build how i think it is suits me best.
With the rune set u get a little boost in crit rate (10%) to crit some minions and get more minion kills. The other runes are for 20% attack speed, because my build is not on attackspeed.
I think mainly the start is very mp consuming so i buy manamune first, to build up some attack dmg first with stacking mana and get the higher manareg. the other items are self explaining i hope.
this is no ultimate build and my english isn't so well. ^^
