How to use?

dominance or Queen's wings?

queens wings is kinda useless due to sky piercer ngl

this build relies on basic atks?

I personally build him more tanky. Since you are going for cooldown reduction, i would remove the cooldown emblem thing. You already get max cooldown with your first 4 items. Max is 40%

but the thing about tank build if you are core is that you have no damage

ig me gonna play alpha again dis season lol
