Fire Emblem Heroes: 1 Stars vs Abyssal M!Jörmungandr

Jörmungandr is tough...unless you beat her Iron Fighter's defense check, then she is perfectly manageable. The solution was therefore quite simple: supercharge Gunter and let him sweep. Inheriting Patience to Gunter enabled him to one-round Jörmungandr while Impetus Guard was failing both the one-round and dealing with the follow-up mobs. Not difficult at all as long as the extra mobs don't get to spawn. Music: Erza Descends - Fairy Tail
