Bargain of the Cursed Mage

The red gem of the ring is like a droplet of blood, but a faint hint of oddly colored flame lurks within its depths.

As an action once per long rest, you can channel your fury into the ring to produce an inner beast, which crawls forth from your flesh in a painful but undamaging display. Your inner beast takes the form of a stunted, lupine humanoid, operating on your initiative and following your mental commands to the best of its ability. It has the same stat block as a werewolf, but has no damage immunities, and lasts for one minute before collapsing into shadows that retreat into your form. While your inner beast is active, your melee attacks deal 1d6 additional force damage and you have advantage on Perception checks that rely on hearing or smell. If your inner beast is killed, you must make a DC14 Constitution saving throw. On a failed save, you are stunned for one round and take 3d8 psychic damage.
