Carrying bear teeth to find hares and birds
From UnReal World Wiki
Bear is a great hunter who always finds its prey, and hunters who carry bear teeth with them can come across hares and game birds as they please.
Carrying bear teeth to find hares and birds is a spell of sorts that imbues the character with the bear's hunting ability. The teeth must be gathered from bear's skull before completing the bear skull rite.
The amount of teeth carried does not seem to affect the effectiveness of the spell.
