You probably shouldn’t be able to sit by a campfire to heal up during a boss fight. Might want to rethink this fight a little bit.
usually that boss spawns an endless torrent of flying adds. He stops when he is at low HP (most bosses stop summoning when they have less than half HP left), so your vid is kinda flawed.
you can do the same with all non moving bosses and even ones that can move, as long as the place is big enough
That’s only because I didn’t think to record until late into the fight. Even when he was spawning the monsters, the monsters were just hanging back by the boss and leaving me alone while I sat to regen.
