And discard Boromir to give all of them 2 damage?
Yeah if you get desperate, but you can also have him defend over and over again. With a Gondorian Shield equipped he shouldn't take much if any damage and then you attack them all with him. His 3 attack is enough to take them out in one hit. Takes a bit of threat to ready him over and over again, but you can pair him with Lore Aragorn for a reset if you need it.
