Well that was fun going through a lot of my units to figure out who can actually tank it. With Phoenix my Prince and Sybilla both got 1shot, Sophie barely managed to survive but her ability runs out before he's even at 80% health, Bernice managed to tank him the whole way, each shot doing about 85% health, used 3 healers to keep her up.

Got the armour 1st try, only have 1 drop left now, Maribel is already min costed so shouldn't need to touch this one again soon.
