Muckbane is an extremely valuable and useful weapon for players in DDO. Muckbane is a club that cannot be destroyed when fighting oozes and slimes, this is very useful because normal weapons will be destroyed very easily by oozes and you will be left with no weapon in the middle of a dungeon. If you have Muckbane you can simply switch over to using that and your weapon won’t be damaged or destroyed. This can also be used as a platinum guide as Muckbane can fetch up to and probably more than 20,000 Platinum.
To start the quest go talk to Durk the Deranged in the harbor, he will give you a quest called your Durks Got a Secret. Accept the quest and head into the sewer entrance right next to him.
Complete the quest by killing the two Kobolds brothers then go to the area marked on the map and see if muck is there, he does not spawn every time. If you are level four or higher you don’t have to fight every mob, you can just to run straight up to the two brothers and kill them then run and see if muck is there while ignoring all the other mobs, they will hardly do any damage to you. If he’s not there recall and repeat the quest. If he’s there kill him and open his chest, if you’re very lucky you will get the Muckbane but that doesn’t drop every time. It usually takes me about 10 runs through the instance before one drops.
