Bone Wolves first appeared in the Bloodmoon expansion for The Elder Scrolls III: Morrowind. The pet Bone Wolf will not fight for you, but does grant the Bone Wolf's Revenge perk while in your company, increasing your damage against undead and necromancers by 25%.
This Creation adds Bone Wolves to the game as generic enemies, as well as a quest to obtain one as a pet. (Quest 'Let Sleeping Wolves Lie' starts by reading the Letter from Bolgeir Bearclaw delivered by courier after completion of 'The Wolf Queen Awakened'.) Overview A faithful companion with a bone to pick, this skeletal pet will reward your friendship by carrying items and boosting your damage against the undead. Official Summary Despite being raised by necromancers, a Bone Wolf's true loyalty is earned through actions rather than magic.
