Alright so this is my tentative plan for Bunny Camilla's abilities:
Weapon: Leaving Green Egg+, for flavor and because I don't want to 5* something else just for its weapon. The spell is actually pretty bad since it's a nonbo with one of her other abilities.
Critical hit: Glimmer I guess? I want something that charges relatively fast. Could maybe use Draconic Aura instead because this Camilla does have huge attack.
Skill: Might as well use Rally Attack because I don't really use anything else that has it.
A ability: Leaving Defiant Speed for no better reason than that I don't want to pay extra SP for something else. It's not awful, just asynergistic with her weapon.
B ability: Probably Draw Back to enable some hit-and-run kiting tactics. Seens handy with a mobile ranged attacker.
C ability: Threaten Resist to help her hit even harder and synergize with the rest of my team, which is already mostly magic damage. I'd have to inherit Ursula to get this though and I'm actively using my 4* of her right now.
I want that Spring Xander due to the badge pick up ability like hell I hope they keep them in the summon machine when it's over.
What on Earth do you need more badges for? Are you finding yourself running out of them? I can't figure out why that ability would be good at all personally. Unlike Chrom's obviously amazing experience boost ability.
