theres no direct mention of it as far as i know, but its probably safe to assume that it would be like a raid or dungeon boss fight in most mmos. there were a bunch of traps and mob NPCs on the way to each floor guardians room and as they went through the floors they lost more and more members (i believe theres a penalty system for dying, so simply respawning and trying again would actually work against you in the long run if you couldnt do it on the first few tries). its also implied that most attacks on nazarick were probably small scale groups attacking so they never made it far, however that one giant raid did manage to make it all the way to the 8th floor, but encountered an unkown obstacle that caused them to wipe and give up (since it was probably too OP to try and beat)
