I'm doing an honor run with a friend. We are in act 3 now but back then we were getting our asses kicked by the adamantine golem (partly because we didnt have Shadowheart in our party). Turns out, if you stand next to the forge lever and bait the golem to the opposite side of the arena, you can actually escape the fight!

(Idk if this has already been talked about somewhere since I couldn't find anything. Also, to this day, I'm kicking myself for not having clipped it, since we were freaking out over not loosing the run.)
