Welcome to my Ashe Guide, hope you try it and let me know how it works for you.

For better Armor and Magic Resist and to be able to last hit better while in-lane.

Work with the Champions passive in order to do better and to find good combinations for that champion, I build the Phantoms for the Critical strike mainly, but the attack speed and movement speed are just great bonuses as well.
Obviously the Infinity Edge and Bloodthirster in order to more damage.
Plus the additional Critical strike chance and damage increases.

1. I max my Hawkshot first or second, it is much more effective if max first. Not only does your portable ward have more distance, but the passive is much more noticable.
If by end game you have 200+ minion kills that around 1,000+ gold that you wouldn't have otherwise.

~If going for massive kiting, max Frostshot first then Volley.
~ If you want more harass, then max Volley first, followed by Frostshot.
~ If your main goal is to get minions and "farm it up", than max Hawkshot and it will be an added bonus.


***** Remember to not keep your Frostshot on for to long, If you do, then you will have manna problems all game.*****

Ashe is one of my favorite champions and is a great Champion.
I have played 300+ matches as Ashe and have won more than Half of them and have used this build in nearly every one of them.

Try it out for yourself and let me know what you think of it.
