For a bossfight, he's pretty lackluster. Yes he has an unholy amount of hp and also his servants but they mostly die in one hit, but he acts pretty much the same as the average sword dummy. Same behavior, same predictability, and he has no special skills to make up for it. Plus idk if this is intentional but parries and wrench parries stun him for an ungodly amount so you can just chip damage for free
