Investigate the Drudge Fort near Cragstone for Jarvis Hammerstone.
Before heading to the Drudge Fort make sure you have multiple food items to feed Sergeant Shanks in step 3 and Farmer Kao's Shovel for step 4. Most groups choose to omit these steps and instead have someone PKL through the cave door. If your group is doing this, skip steps 3 and 4.
Head to the fort, destroy the walls, and work your way to the inner ring of the fortress. You will find two NPCs: Sergeant Shanks the Drudge and Hoogan the Banderling. There is also a cave with a locked door.
Give Sergeant Shanks food items until he slips and tells you about the blueprints. This flags you to pick up the Drudge Fort Blueprints dropped by the Drudge Biters surrounding the cave entrance. You only need to get flagged once per character and then they can pick up blueprints forever. Not many of the Drudge Biters drop the blueprints, so you may need to do some searching to find them.
Bring the blueprints to Hoogan the Banderling, barricaded inside the small hut. Note that you cannot enter the hut, instead you must interact with Hoogan via the small window in the back of the hut. Give him the blueprints and he will tell you that he requires a shovel to escape. There is a rumor sitting in a pile of trash and stolen loot which will lead you to Farmer Kao, the owner of the only shovel in Dereth. It saves time to get Farmer Kao's Shovel before the quest. Give the shovel to Hoogan in return for the Cave Door Key.
Use the Cave Door Key to access the Cave Dungeon. You will enter in a tunnel which connects to a large chamber. Opposite of you will be a portal to the next area. In order to enter it, you must first kill Kernel Klank. This will release the restrictions on the portal which takes you to the main and final dungeon, Under Drudge Fort.
Under Drudge Fort is a large maze, but experienced players will know the way through. If no one knows the way, study the map carefully. Eventually you will jump down to the lower level where Bonecrunch is.
If you don't have the map: Once your portal to the lower dungeon, go straight until you hit a wall; go right 90 degrees until you hit a wall; go left and stay left until you go down a ramp; at the bottom of the ramp, stay right until you reach a balloon and a jump down.
When you reach the final room, there is one important thing to remember: Do not kill Captain Burnja. Killing Burnja puts out the Wall of Fire and lets Bonecrunch into the main room where he can and will lay waste to the entire group with his high hollow damage. The general strategy for the final room is this:
Have one ore more players lead Burnja off to a side room and hold him there until Bonecrunch dies.
Have an archer open the door behind the fire wall and lure Bonecrunch with an arrow.
Have all archers and mages open fire on Bonecrunch. Slashing ammo with a rending bow is said to be best.
Melees keep the spawns of drudges clear so the archers/mages can stay alive and concentrate on Bonecrunch.
If anyone dies, they can portal recall and land at the top of the Under Drudge Fort
When Bonecrunch dies, it is then safe to kill Captain Burnja. Once Burnja is dead and the flame wall is down, have everyone in the fellowship loot Bonecrunch's Chest Key from his corpse.
Captain Burnja carries 1 special board with nail that can also be turned in for a small amount of XP. He also drops Burnja Token that can be given in for a title reward.
Once everyone has a key, exit the dungeon using the Escape Portal that appears behind Bonecrunch's throne. Using this portal is what flags you to get a reward from Jarvis.
Close the chest, if open, and then unlock it using your key.
Tip: You can tell what item is in the chest by looking at the burden:
Orb = 9140 BU
Scroll = 9070 BU
Hammer = 9840 BU
When finished, use the surface portal and run back to Cragstone and speak with Jarvis for experience and a random title reward.
Optional: Unwanted items can be traded or turned in for bonus experience.
If you have more than 1 fellowship, you will need to kill Bonecrunch more than 1 time so everyone gets a key. To do this safely, everyone should move back to one of the side rooms and wait for Bonecrunch and Burnja to respawn. If you do not, there is a chance that Bonecrunch will get beyond the flame wall before it can respawn.

You give Hoogan Drudge Fort Blueprints.
Hoogan looks the blueprints over.
Hoogan tells you, "Alright, we know we need to dig to avoid these tunnels the Drudges dug here and here, but we don't have anything to dig with. If we had a shovel we could really get out of here."
Hoogan tells you, "Can you find us a shovel? I don't know what the drudges used to dig their tunnels, but maybe you can find a clue around. If you bring me back a shovel I'll give you this key we slipped off of Shanks when he was sleeping today. I think it leads into their tunnels below."

Hoogan gives you Cave Door Key.
Hoogan tells you, "The tunneling is going much faster now that we have the shovel you brought us. You should use that key I gave you to get into the Drudges under ground caves. I'm pretty sure their leader is down there. At least that's what Shanks let slip :the other day. Thanks again human and good luck."
Bonecrunch says, "Stay away from my apples!"
Bonecrunch says, "You! How did you get into my fortress? Never mind, now it's time for you to go crunch!"
Bonecrunch says, "This is my throne room. I am BoneCrunch and that's my throne. There, tours over, now you die."
Bonecrunch says, "Your time as masters of this land is at an end humans. You have no idea what is coming."
Bonecrunch says, "You have defeated my child. Your kind shows just as much promise as the Martine creature did. Soon you will embrace the simple truth. Clarity and purpose will be paid for with free will."
Bonecrunch says, "Your not part of the Plan!"
Bonecrunch says, "What? You call this loot? How come I never get your weapons?"
Bonecrunch says, "Come! Protect your leader! Bite! Stab! Burn!"
Captain Burnja tells you, "Leave now humans or I burn you so bad you be dead!"
