Ok...i was sent to get the bonebiter bow in the urshikatu burial grounds. I went to the room were the ancestrial ghost that had the bow was and I killed it. I thought it was like any other ghost so I left the pile without inspecting it. I left the whole burial grounds. I found out that it was not a normal ghost so iwent back and it wasn't there. No bow no nothing. Now I can't complete my mission! What should I do??!?!
