One of the best effects that Ashe has against champions is her snare. While it is nice, many champion abilities allow the opponent to teleport or many summoners have the spell that allows them to jump back and forth as well. This build first addresses these problems with boosts to attack speed, movement speed, and even a slight mana boost that will allow Ashe to flee from champions, rush back up to champions, and continue to snare them with both the passive Trinity Force ability and the active ability of Frost Shot. Once you're able to keep their speed in check, then you can then begin to build attack damage for the better part of the end game. Some armor penetration is added at the end to further create devastating effects as Doran's Blade is dropped for the Last Whisper.

First build posted ever, btw. I would appreciate any and all criticisms.

Thank you,
