Forgive me if this is a dumb question, but I noticed that minibosses do not regain health whn you leave and return, but Leiutentants do. Is this supposed to happen? I died while fighting a miniboss (Curse you Jevel the Gruesome! That was my first character!) and then came back with a second guy and the boss was at the same health I had left it at. Then, I was fighting the leiutenant (No small matter, he was twice my level) and hit the wrong hotkey by accident. that was my "Warp to map" Scroll, so I came back and He was fully rehealed. He was at 4000 of about 300000 health, I'd just spent quite a while kiting him around. Are leiutenants supposed to recharge differently?
I beat him anyway, though. That was a really epic fight, more stressful than attacking an AI homeworld.
