I searched for this and couldnt find it anywhere, but im sorry if this is a repost.....
Okay i found a way to make it so you can resmash the pumpkin head of the HeadlessHorseman!
As far as my knowlage this only works with the Brill HHM (Level 11 one)
So you killed the HHM with that group of people that camp around brill for like 4 hours... Then (heres what i do) i made a trial account and tested this and i was level 3, and after i looted the head once, i went to the zepplin to ORG, and when it reached about the forge i jumped off and died, then i found my body and rezzed, then i walk over to the pumpkin head and BAM! you can re-loot it! I also found a more effective way if your a low level, you loot the head once then you walk over and attack one of the mobs (level 6-8 usually) and im only level 3 so i let them kill me, and then since im such a low level i just use rez at the spirit healer and i dont get sickness so then i go and reloot it! This will probley be patched soon so go do it while you can! I got x18 Weighted pumpkin heads! twocents
