Instructions
Send the tank to attack Fenyang, and use a healer to keep him alive.
Position one damage dealer at each of the doors in to the room. Ideally, these two positions should be ranged weapon users so they can grab the fanatics as they enter the room. The players must kill the fanatics as quickly as possible to prevent them from jumping in to the pit in the middle of the room.
Attack Fenyang with the other four players in the group, with the healer focusing on using healing spells to keep the tank alive. If one of the damage dealers on the door is getting overwhelmed, send one of the characters attacking Fenyang to help. It is essential to keep the fanatics from jumping to their deaths; if you can do this, the fight should end quickly.
