Idea?

I think it is the person who killed the monster, because when me and CS were taking V Hard mode at Lv40 multi mode (we had our asses kicked btw), we were attacking a Hildebear. I died and CS killed it. The result was Hildebear Head. Now the thing is I was the host (Id was Skyly) and yet there was a Yellowboze item. SO...theres mah evidence on that matter
*goes to corner and eats caek* (THATS CAKE BTW, NOT CACK)

maybe it was cuz u were dead??
