Despite the first monster dropping a set equipment, they had not managed to farm many others later on. After the party cleared the entire floor, they only managed to find two of the same gloves, and one pair of boots. One more, and they would have a complete set.
Although it was not stated in the official site, the party could have easily figured out there were more than 7 floors in this crypt. If each of the monsters in the crypt could drop the set equipment, the party would farm a few sets of equipment by the time they reach the bottommost floor.
