Players should know that there are a total of 10 waves of Barbarian Assault, with the last wave containing the Penance Queen. Players must play the waves in order from 1 through 10. The lobby contains a total of 11 rooms, one for each wave plus the "arrow room". The arrow room matches you with other players that choose to enter the arrow room. In order to enter this downstairs area, the tutorial for Barbarian Assault must be completed. There is no way to skip it.
