Level: from 30
You need: Fatigue 25 and Grp 3er
Time available: 3 h
This instance can be mastered with 3 players, but of course it depends on the equipment and experience of the players.
From the bosses you get green or blue level 30 equipment and also artefacts. All other monsters drop trefasteins and other loot (which you can sell).
Tip: Pay attention to the map and run down the mountains from left to right. Stay on the path (don't cross the bridge at the third mountain, otherwise you will miss mobs) and kill everything in your way.
Important: Make sure you complete the quest with the drums before you log out, otherwise it will reset and you will have to do it again.
