A bear cave can be found in the Upper Farmlands of Ehb, laying downhill from Lady Montbarron's estate, in a valley, near a lake and a farmhouse. During the Krug invasion of the farmlands, Montbarron killed the resident bear singlehandedly on her way to Stonebridge. Within she found Altan's Leather, a suit of leather armor that increases the wearer's vitality.
The cave mostly consists of short branches, containing crates. This suggests that the cave was used for storage before the bear moved in. The bear can be found in the very back of the cave.
