Leaving the dungeon and 'cleansing' will restore your negative levels. Otherwise, orgasming inside of a dungeon causes you to lose a level. The problem of course is actually Leaving the dungeon, as most witches don't like their prey getting away.<br/><br/>As far as diehard is concerned... I'd rather you didn't take it at all, but I suppose if you did then it'd just give you a few more points of endurance. I guess you could flavor it as being able to move and act while cumming. Which would be rather humorous actually.
