Rag and bone man wishlist

So i'm doing the second part of rag and bone man.
When I kill the monsters they aren't dropping the special bone. I haven't done this part before so i'm not sure if im missing something..

any help?

 

did you check your quest log to make sure you are at that part? do you have one in the bank?

 

They aren't a 100% drop, but you can check your bank to see if you already have one.

 

Did you already complete the first part?

 

They are not a 100% drop. I have a quest cape and i have done the quest and the mini-quest afterwards.

You have to farm the monsters until they drop the bone, which could be 1 kill, or could be 20, hang in there dont quit after a couple kills.
