Cloak of the Wolpertinger

Cloak of the Wolpertinger

This bizarre hooded cloak appears well crafted, if a bit strange, sporting a weave of brown and gray feathers down the back, and a pair of small antlers attached to the hood. It was crafted by a talented but eccentric wizard who was obsessed with wolpertingers; mythical animals said to resemble rabbits with wings and antlers. So great was this obsession, he actually magically altered a population of rabbits to ensure wolpertingers were no longer mythical! It's unknown what became of them, or how many of these cloaks were made. To this day, however, new ones continue to be found.

The power of the cloak is straightforward. Upon attempting to invoke the cloak's magic, the cloak merges with the wearer, transforming them into a wolpertinger, either rabbit sized or the size of their natural form. The size is randomly chosen if the wearer doesn't choose. This form is fast, agile, capable of flight, and rather strong at larger sizes. They can still speak, and the transformation lasts as long as the wearer likes, and they can transform to and from this form freely.

The wizard, while powerful, was reckless in his methods, however, and the cloak has a notable flaw unknown it its creator. Every time the wearer transforms to or from wolpertinger form, there is a chance of the cloak's magic failing. The base chance is 0%, increasing by 1% for each use after the first three. This chance resets when the cloak has gone 8 hours without transforming. In addition, the user cannot transform directly between large and small wolpertinger forms. They can only access either form from their natural form.

When the magic fails, the cloak immediately and permanently vanishes, often leaving the user in a partially transformed state.

01-20	The user is left in their natural form, without the cloak.
21-60	The user is trapped in wolpertinger form. If originally humanoid, they have a 50% chance of becoming anthropomorphic.
61-70	The user is left in their natural form, but with a wolpertinger's head.
71-80	The user is left as a wolpertinger, but with their natural head and upper torso.
81-90	The user is left in their natural form, but with antlers, buck teeth, and small, vestigial wings.
91-100	The user is left in their natural form, but with antlers, buck teeth, wings, furry arms, a fluffy tail and/or furred, digitigrade feet. 50% chance for each.

If the magic fails while transforming to or from the smaller size, roll here, as well.

01-50	The user retains their normal size.
51-75	The user is trapped at rabbit size.
76-100	The user is trapped halfway between normal and rabbit size.

For a victim of this failure, there is no magical effect left to dispel or cure. They can only be returned to normal by additional transformative effects.
