Btw slows don't stack so this is why it's experimental pls give me feedback of how this went for you.

Now for summoner spells your gonna have a lot of attack damage which means you will be chasing and being chased a lot you should take teleport cause it can get you back into lane or a certain area in a tight spot exhaust because for chasing Ashe slows down with her passive and abilities anyway having more of that gives you more trade and you get fed if you do t lie, this version exhaust and ghost is also a good option plus movement speed and a slow for running and offence.

Now one of ashes strong points is her ability to slow people not drastically at first buts as you level your passive gets stronger and so does your other abilities your enemy gets slower and you get faster and stronger ashes w is good for poking at all stages of the game it adds a lot of kill pressure on your enemy as well your e also helps you plan perfect tanks and trades that get you fed and stronger and your q adds a lot of pressure your ult is very important never use it reklessely always make sure if you ult unless absolutely necessary and you need to get away always follow up on the ult.

Obviously cause this is a super slow attack damage build we are gonna use glacial augment to complement your blade of the ruined king and activate freeze ray and we can deal a hell load of damage during game.

These items do a lot of damage freeze and are perfect for chasing,vision and trading but you've got to have a decent skill level to use this build to its max potential.
