NEED Ashe Tips :)

Pros: Long range, consistent damage, powerful slow, vision spell, good initiation and peel Cons: Immobile, lacks burst

Since her recent rework, Ashe has been all about huge damage in long engagements. Ashe doesn't get random crits, but the damage of the "mini-crits" she gets from her passive is actually higher than the expected damage anyone else's auto-attacks would do at the same AD, Crit Chance, and Crit Damage. The flip side of this is that she can't burst people down with lucky crits at the start of a fight. In fact, she can't crit on her first attack unless she already landed her W or R.

Her Q is an amazing steroid. It makes her slow stronger, it gives her a pile of attack speed, and it greatly improves her auto-attack damage if she uses it with five stacks. As Ashe, try to either build up five stacks before engaging or wait until you have five stacks before using it. Don't be too afraid to pop Q early if someone dives you or might escape without the extra slow though. Against Ashe, try to either burst her down before she can get her stacks up or whittle her down with short trades.

W provides good poke and slow. Its range is a little longer than her auto-attack range. The idea trading combo for Ashe is still auto -> W -> auto, but feel free to poke with W alone if you get a chance. It's also good for kiting opponents because you can slow them from well outside auto-attack range. Against Ashe, try to stay behind minions or tanks so she can't hit you with it.

E is a very versatile global vision skill. I like fire E up the river to check for incoming ganks, or check on jungle monsters like Dragon or the enemy team's buffs. It's also great when chasing enemies to stop them from juking you in a bush or to see if they're baiting you into an ambush. While it does have an ammo system, most Ashe players won't level it until late game so it has a long cooldown. Try to keep track of when she uses it during laning because she's more vulnerable to ganks without it.

Ashe's R is great for forcing kills in lane, picking up assists from across the map, and initiating teamfights in the late game. If you can land it on a carry out of position, that carry is either dead or out of the fight. In lane, use it to chain CC with your support either by initiating with the arrow or waiting for your support to CC them for the guaranteed hit. Keep an eye out for opportunities to help your allies in other places too. Against Ashe, try to bait her into firing her arrow and missing, then engage when it's down. Also watch out for stray arrows: it's a global skillshot, so even if she misses her intended target she could still hit you.

For Runes I run flat AD marks and AS quints. Because of her passive 1% crit chance cheese is useless, and you'll get better scaling damage with scaling AD runes than critical hit chance runes. I'm not sure about crit damage runes though - I heard there was a bug where they were multiplying her damage instead of stacking the way they should but it might have been fixed.

Like most ADCs, she should be running something like 21/9/0 masteries. I've been using the new Tenacity defense mastery. You definitely want Fury in the offence tree because Ashe's passive helps it rev up faster.

Ashe probably works best with the standard ADC build because it provides huge single-target damage. Infinity Edge is too good not to rush, and you usually want to follow that up with a Phantom Dancer, some lifesteal, and a Last Whisper. If you've got another heavy source of physical damage on your team then The Black Cleaver can also work well on her because she can stack it quickly with Q and scales well with cooldown reduction.

If your team needs waveclear or you are very confident in your tanks' ability to peel for you, consider building Runaan's Hurricane. It deals reasonable AoE damage, but more importantly it lets you get stacks for Q quicker. I try to rush IE and a Zeal, then consider whether building Hurricane will be a good choice that game. If you build it too early you don't get enough damage from it, and if you wait too long the game will be over before you can finish it. I generally try to build BC and BotRK instead of LW and BT when I build Hurricane, but really anything goes.

Interesting comment on the Armor of Thorns; when your team has no tank or the tank is not effective, and the enemy keeps getting to you, Armor of thorns is good if Physical dps is killing you, if magic dps is, HexDrinker/Maw has saved me more times then I can count with that shield and the other item that blocks an enemy ability. I find the Guardian armor a waste, it just takes them a few seconds longer to kill you, it doesn't help you get away, and the AR/MR of +50 is ineffective mid to late game.
