Quick riposte is the best budget skill that comes to mind
Also why don’t you change the seal to close def? I think it’d work out better
@Banraku has one
Quick Riposte is a cheap and strong B-slot for him
Lull Atk/Def is what I’m running but that’s pretty expensive
Lull Atk/Def B and Quick Riposte Seal is probably the best thing to do.
