Wrath of the Bear God

Any creature struck by a critical hit, either from a natural attack or from this scimitar, becomes a target of lightning, as per the Call Lightning Storm spell (5d6 damage, 24 DC Reflex half). All natural attacks from both the wielder of this scimitar and the wielder's animal companion have concussive and shocking modifiers applied to them. If the wielder is wild shaped into a bear or if their animal companion is a bear, the sonic and electrical damage from their attacks is increased to 1d10.
