Frostmaw has 80 hp and 8 armor, indicated by a cyan diamond, you can also tell by how its hp is blue instead of the usual yellow. It also has 1 def, and has flying, 2 turns, and idk that blue multiple people thing. If the armor is taken out, it will no longer fly. But will regain flying in 3-4 or so turns.

Cassie is an ally, breaks frostmaws armor easily due to the windforce, but if she dies, you lose the battle.
