Spawn time for this room is a tight 18 minutes - the same as the Chief. While I haven't checked every single spawn in the zone, I'm fairly certain every single one follows the same timer (angry goblin not included). The named of course have Place Holders and will not spawn every time. The room can be solo'd by a 55 bard (me) although breaking the room is even tougher than breaking the Chief room. Good luck =)
