The five Apprentices had a short discussion before they entered the first battle room. There, they noticed that it was a large circular cavern with many doors spread out all around them, and a large double-door directly opposite the entrance to the room.
Once they entered, the door behind them closed shut. This was a compromise Xela had to make in order to follow the rules of Dungeon Cores, which was that of mutual benefit.
The adventurers got rest stations, so the monsters got a nice 1-on-1 time with the adventures where they could not retreat unless they cleared the waves.
If one did not have enough teammates, or had pig teammates, it was likely that instead of reaping rewards, one would reap a quick death.
The group of students took the battle formation that they had used against Gunner immediately, Ash with his sword, Reina with her bow, Jonathan with his broadsword, James with his dagger, and Anthony with his bo-staff and nimbus cloud.
