This is a simple guide to get the most damage with critical hits.
I want to try it because ashe's passive is awesome for first blood and late game she's a good carry

Pros
Awesome damage when crit
High crit rate and damage when get items
great chasing (great speed with phantoms and slow with q)



Cons
squishy
focused, like all carry's
poor early if you can't use your passive

simple, great crit damage (which it can only infinity edge do by items) and marks of arpen, because i don't get last whiper, masteries and marks it's ok if the other team doesn't stack so much armor

like most carry champs, great damage by 21 offense, 5 points in defense, flash and reduce time dead in utility

I start with doran's for survavility, next I get boots for movility and start stacking crit, avarice and zeal for starting. Then we need a bit ad, bloodthirster is a good choice. after that i update zeal to phantom dancer and go for infinity edge, starting it with cloack of agility, then I think black clever is the bests choice, time to get a defense item, it's your choice depending on your enemy and if you got more money you can change boots for other phantom dancer

It's my first guide and I don't have so good english but I hope it will be ok :)
