Magical cloak that acts as armor. Protection against normal and magical attacks as well as holy spells. Gives creatures who are harmed by light and sunlight immunity. Give wearer the ability to become invisible at night. Sentient and cursed. See full description for details.
In the middle of an unimportant combat with some bandits a burst of wild magic transforms all of the PCs and their opponents in to random animals and monsters. They retain their intelligence (though not, of course, the ability of speech). They can either carry on the combat in their new forms, panic, or otherwise react how they see best. After about an hour, they return, unharmed, to their normal form.
