You can start picking good habits now or just do it later.So the final combination of stats/substats are: C.The required stats/substats that increase her survability is also DEF%.The required stats/substats you are looking for to improve her damage is: DEF% (higher damage multiplier), and ATK% (lower damage multiplier).So the required stats/substats you are looking for to make her skills work are: C.Peydma's A3 steal buffs, which also requires accuracy.Peydma's A2 applies Decrease Accuracy debuff, which requires accuracy too.Her damage also scales off of attack, but just a little bit (in the description you can see ) whichever stat comes first in the description (in this case ) is the one with the highest multiplier, which generally means more damage. Peydma is a defense based champion, so her survivability and damage can be improved through dedef% substats.Thefore the combination of substats you'd be looking for in your Peydma is (critical rate + accuracy).In order to apply the AoE Decrease Attack you need accuracy.
