This large helmet is wrapped in the hide of a bear’s head, with metal teeth worked into its visor.

While raging, you can halve the damage dealt by a single sneak attack or critical hit scored against you. You can activate this item after the damage from the attack has been determined.
A bear helm functions once per day.
