For starters..this is my first guide. Ashe is a Ranged Carry, meaning she is terrific late game and somewhat towards the middle.

Start off by getting a Long sword and a health pot. Those two items will sustain you till around level 7 for when you can return to your base to buy the beginning of the Madred's Bloodrazor (ie. the Madred's Razors) and boots. If you've farmed well enough you should also have enough coin to purchase the Recurve Bow but if you haven't no worries you can always return for that later. The Recurve Bow is definitely the next item you should buy however due to Ashe's lack of attack speed. After the Bow finish off the Bloodrazor and start on the Nashor's Tooth. I'll tell you the reasoning for the Nashor's. Attack speed, CD reduction, and AP. Ashe's ult is AP which combined with Nashor's will allow you to hit close to 700 once you hit level 16. That and the CD of Ashe's arrow is right around 45 seconds which is plenty of time for you to spam that arrow and volley combo for a deadly punch. Back to the items; Once you're close to finishing or have finished the Nashor's finish your boots because you're going to be targeted like no other. Great! We're almost done. Now Ashe is putting out some decent damage but not enough to take out the heavy hitters. Start working on the black cleaver. The extra attack speed will come in handy for late game. Once your finished with that move on to the phantom dancer for the critical chance and even more attack speed. Lastly buy your deadly Infinity Edge. I don't like buying this first like some Ashe builds because it uses all that gold and while I'm getting doubles and triples they are still saving for their Infinity. It's just a personal choice.

The Summoner spells that I use are Clarity and Flash because I mash my volley a ton. Volley is a terrific way of keeping the creeps at bay and doing some damage to the enemy champ. Flash is your panic button. I realize there is a long CD on it but abuse it if you need to. If you see a great shot with your arrow take it flash in and volley. The enemy champ usually run because their health is practically gone and that's when you turn on your Frost Shot to slow them down. Use only when they run otherwise you'll run out of mana like no tomorrow.

Overall Ashe is by far the best carry in the game. There are many builds out there and I just had to make one. If you want to experiment with the build you can. Rearrange the order, comment and thanks for taking the time to read all this. Have a terrific day! =]
