Magician %/s (KMS FLY 2 & GMS Dawnveil)

From what I see, the only true difference is they get both Dark and Light Affinities. Don't they still need to use one type to enter Equilibrium?

They charge the feathers and once the feathers are charged they can consume one charge to enter Equilibrium and then pop-out in Dark mode. Depending on the cooldown on the swapping modes, it might be more damage since you could spam to Equilib. a few times in a row.
