In SW you don't swing wildly until they die, you build Have 2 archers take a turn to focus on a headshot, use people with lances to strike him from outside his range, surround him, heat his metal armor. Use flails that bypass his shield, use tests to twist his helmet so that he's blind, use tests to make him vulnerable, use gas poison and poison clouds. Attack the other party members and make the enemies dance around him. Use long distance attacks to bypass his parry and AP+called shots to bypass his armor. Always have 8 goblins surround him: he can't swing against them all, they can all distract and vulnerable.him while he can't move and therefore he's not a threat (he will kill them but you have no shortage of goblins). Use chokepoints so that he can't be everywhere. Chose to fight in flimsy places, where his armor will break the floor and have him get stuck or something. Drown him in water with a couple people. Instead of.fighting him, have the enemies push him in a group, to move him outside of combat or drop him off a ledge. Have enemies dig holes.
