Cloak: Furskin Pelt

Unlike many pelts worn into battle, a Furskin Pelt contains the spirit of the beast it was harvested from, allowing its wearer to embody the beast's most ferocious characteristics.

Bestial Rage. When you enter rage while wearing this pelt, you enter beast form. The pelt melds with your skin, its fur becoming your fur, while your eyes begin to glow yellow and your teeth and claws grow to mirror those of the beast the fur was taken from. While in this form, you have a +3 bonus to Strength based ability checks, saving throws, and attack and damage rolls. You also have an additional 10 feet of movement speed while running on all fours.

Bestial Weapons. While in beast form, your only weapon proficiencies are with your claws and teeth, which are both strength-based unarmed attacks.

Claws: 1d8 slashing damage. When you make a claw attack, you may make one additional claw attack as a bonus action.
Bite: 1d12 piercing damage. When you kill a creature with a bite attack, you gain 2d4 temporary hitpoints that last until your rage ends.

Curse. A Furskin Pelt is a cursed item, and attuning to it extends the curse onto you. While attuned to the pelt, you cannot remove it.

Additionally, you are vulnerable to damage from silvered weapons and you count as a shapechanger for the sake of effects that target shapechangers.
