I just took down the bloodtusk mammoth with its supposed reward, the bloodtusk mammoth skull. All nice and well, but that made me wonder two things: what exactly do I do with it... and where is it anyway? Surely Ubisoft didn't forget to include it in the game? That would be something I'd expect from a third rank game designer but not from the great and mighty Ubisoft. Which means I must be overlooking something. Any of you folks discovered by now where that skull is and if so, what its uses are?
A quick search on Google showed me a few people are wondering the exact same, I haven't found anything close to an answer.
"After killing the Mammoth be sure to collect the Bloodtusk Mammoth Skull from its corpse before leaving the area."
