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.
You will easily take command of the game, quite early on. Farm those minions and get those lifesteals early on and the game will be yours. Your Ultimate is a skill shot but I find it quite easy to hit someone. It will go through walls and Minions, and wont stop til it hits something, or just hits the border. That's about it, this is my first build that i've made for this site please tell me what you think. Have fun with this buld, if you're experienced with Ashe I guarantee you will be winning nearly every game.
