Draiss decided instead to force further, going one past the nasty fight, just to prove he could. He was cut up, beat up, bleeding, and standing only out of a sheer bloody minded determination to not quit, not with only twelve floors to the next and admittedly final boss, and he allowed himself to collapse, resting in the Cave on the floor he had just cleared. Once he was healed and ready for more, he went from blasting to sneaking, using every trick he could to get past the enemies rather than fighting, as the stairs were already there when a new floor was entered, only boss floors had to have them unlocked.
