All the other builds take Infinity Edge, that is the biggest failure I have ever seen in a group of builds, Ashe's passive, frost shot, says that crits don't do ANY EXTRA DAMAGE but instead increases the slow to 60% for 2s. With this build, you can spam your abilities without having to worry about mana and your crits will be useful. Your PD gives as,crit, (runaans as well) and a great passive and is useful with essence reaver, as it's passive is that crits will replenish a certain amount of mana. That is amazing in teamfights that last a while so Ashe is able to poke the enemies out and just hit one champion or minion and get her mana pool back. It also makes her crits worth. There is no need for an Infinity Edge as all it gives is damage and it's passive is made useless sadly, so just get the essence reaver and finish the build with high damage and kiting ability. Since you get move speed from Runaans and PD. This build is super viable in ranked as well. Thanks for reading and if you wanna play some games with me I am more than happy to! IGN : TLEliteZG.
