West Weald Bear Fang are dropped by West Weald Bears, found near the settlement of Shardrock. The fangs are used in the Bear Season quest.
West Weald Bears can be very hard to tackle, even at levels around 20. One should bring a shield, and if possible, have a summon spell to draw their attention.
The bears cannot climb rocks, therefore climbing up a rock or tree allows one to attack unharmed with magic or arrows.
