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.
Whit this build your gonna get around 70% of enemy armor down .... and even on tanks such as ramus or malphite you gonna hit 400 - 500 crits ..... NOthing more can be said about this build.... its just the way i like to play Ashe .... even on early game you hit big dmg because of the HUGE armor penetration u get from runes and mastary.
