I've started to amass enough spare vanilla Camillas that I'm going to +10 a third one. This might end up being a stupid or pointless idea and I haven't run the actual numbers on it, but I'm going to make her a physically defensive anti-armor Camilla.
I'm planning to give her Slaying Hammer (Def Refine), double Close Def, Axebreaker, and probably Aether. I assume she should have no trouble with +10 Surtr, but we'll see.
I feel like we really need a skill that makes units immune to non-attack damage. That would be a nice missing piece in the puzzle toward countering degenerate strategies. I'm assuming it would be a A skill, and best case scenario it would protect from status as well. Or I guess it could be a series of special banner weapons or something. It would definitely be able to be used for evil in PVE, but that's a price I'm willing to pay. In a perfect world a splash damage protection skill would only be equippable by non-armors, but in the world we live in it would probably end up being armor exclusive...
