If you want a amazong ashe build that will make u the best in your team and owning late game this is the build for you. This is my build for ashe and amazing burst a nice attack damage and speed this is te one for u

Some people might disagree but i buy all attack speed runes because they give ashe insane early game compared to others and will help you dominate helping out your build

I go 21-9-0 because for ashe offense you need the attack damage and improved ignite and 9 in utility for improved flash and some other key points

Start with a boots of speed and three health potions to stay in the early fight with the health potions and give you the extra speed with the boots
I go into more expensive items early like Phantom Dancer and infinity edge for crit attack and speed
Finally top it off with Frozen Mallet Atmahs Impaler and Black Cleaver for duribility critical and attack speed

Get a point in on w to start for its slow and good damage than at 2 get q for the slow DONT use q on minions it will burn mana. Use it on champions running away or chasing you
Than grab e at 3 for the extra gold and scouting after get 2 points in w as your main source of damage and grab ur ult at 6 get w at 7 than q 8 finally max w at 9 grabbing q at 10 11 and 13 grabbing an ult at 12 finally max e last at 14 15 17 18 and ult at 16

Get ignite and flash and with improved it will give you improved flash ( lower cooldown ) and ignite ( ability and attack increased while on cooldown) Use flash to get in or out of fights and ignite to make up for no real damage till l8r in the game

Pros
Hard to counter
Amazing late game
High Attack Speed
Good mid or bot
Cons
Weak early game
Cant counter CC * crowd control)
Squishy early
Targeted alot in team fights because of the ad

When some one is running remember you have your arrow try and secure a kill or even steal one

Sit in base at 6 and look for kills to steal

Ashe is a high damage bursty champion that deals nice champion and a nice help to teams and are alot of reasons she deserveto be called overpowerd
