Yup, I agree with what everybody said. Taking out bosses is, if not "easy", very doable with preperation. I had originally screwed up with Yagluth (I went in overconfident and not taking in the health & stamina changes). This cost me 8 lives and my boy went from 60-70 skill levels down to 30-40. Had to run in, collect my tombstone, get back to base, change clothes then back to the fight. Again and again. In the meantime, he had healed up some. Very frustrating, I blame myself, not the game.
