well take plenty of bandages, potions because you can not leave for the first round of the event. the spawn has to be beaten back enough to spawn the timelord and shadowlords to open the rift in moonglow then you can come and go as you please. you need to check the corpses of what you kill/get looting rights on becuase that where the items are, except if/when you kill a ethereal shadowlord suppose to be top 3 damagers have a chance of a drop from them.

also take chivarly or bushido archers and tamers for the win, these characters were doing the most damage to the spawn.
