The bearhead is obtained upon defeating the Kendal during the Mountain Daughter quest. Along with the Corpse of woman, it is proof Asleif Hamalsdotter is dead. If lost you can speak to Hamal the Chieftain to obtain another bearhead for free. It can also be re-obtained at May's Quest Caravan after putting 150 quest points into the Hub Track. You do not have to fully complete the quest to equip the bearhead.

- The bearhead was fairly popular among pures before the Evolution of Combat, as it had somewhat better stats than the iron full helm, and it could be retrieved without gaining any unwanted experience toward the skills they avoided training, but the stats have been since removed, and now the head is simply a cosmetic item.
