[1.1.0] Ashe Guide - Dragon Lane

Your starting item should be a Long Sword , since the Attack Damage it gives will help you last hit the minions during the early laning phase.

As you farm up, Blade of the Ruined King is the first item that you should buy. The built-in passive (which slows the enemy for 25% of its MS from 3 auto-attacks) from this item works well with Ranger's Focus , in which you can proc or activate it with just 2 auto-attacks (as opposed to 3).

Contrary to a default build on any Marksman/Dragon Lane champion, I think Phage is a wonderful item on Ashe since she lacks the mobility to escape with her skills unlike Kai'Sa or Ezreal or Vayne. The bonus Movement Speed on the item helps with kiting the enemies. It is optimal to build this after Blade of the Ruined King but you don't have to build it into Trinity Force right away.

Runaan's Hurricane works well with Ashe's kit, and it greatly helps her with clearing the wave. Blade of the Ruined King and Runaan's Hurricane will be the first 2 core items that you should build for your mid-game fights.

The other builds in the Core Items set are self-explanatory: Infinity Edge increases your damage output and is a must-have on any Dragon Lane champion; Trinity Force is the final item from your Phage ; Guardian Angel is very recommended because champions like Ashe are very squishy.

Your boots should be Gluttonous Greaves , which gives you Physical Vamp (aka Lifesteal); [ninja tabi] (Armor) or Mercury's Treads (Magic Resist) are okay too but I'd prefer building Greaves even if Zed or Akali is fed. For your boots upgrades, [stasis enchant] prevents you from getting one-shotted by a Malphite, Zed or Gragas; Quicksilver Enchant clears away any crowd control effects such as stuns. [locket enchant] is a good upgrade too to help your teammates as well.

Of course, there are situational items as well that you can buy in certain scenarios:

I've seen players build Youmuu's Ghostblade on Ashe as a second item after Blade of the Ruined King , but building this would mean that you are not going to build Trinity Force. Ghostblade offers the MS passive and has a lot more damage that Trinity Force so it's a decent build if you wanna get back to lane faster.

Black Cleaver is another item that you can build from Phage and it gives more health and tankiness. It also reduces the armor of enemy champions. I would buy this in situations when my team is behind or I would get killed pretty easily.

Buy Mortal Reminder if the enemy champions have crazy healing abilities such as Nami, Soraka, Dr. Mundo; but you can build this even if you're not facing them.

Other attack speed items like Phantom Dancer adds tankiness to Ashe and can be an alternative to GA if you're fed. Rapid Firecannon adds safety with kiting from its increased attack range in teamfights. However, Statikk Shiv doesn't fit with Ashe unless you're planning to build 3 attack speed items on her (which I don't recommend).
