Pull to the small room. Step 12 - Begin monk exploration up the misty ramp and to CoM level 3. Again, I'm guessing that the key dropped from the main lords spawned from reavers will open a locked door at this level. We havent made it this far - additional info would be great. Step 13 - DMG or Lev and move up to CoM level 3 when possible.
Ultimate goal is the last building.
No clue what is in CoM level 3, as far as I know , no guild on our server has attempted to go all the way.
