Cloak of the bat

From Ardrana

Fashioned of dark brown or black cloth, the cloak of the bat is not readily noticeable as unusual. It radiates both enchantment and alteration in equal proportions. The cloak bestows a high probability of being invisible when the wearer is stationary within a shadowy or dark place. The wearer is also able to hang upside down from the ceiling, like a bat, and to maintain this same chance of invisibility.

By holding the edges of the garment, the wearer is able to fly. If he desires, the wearer can actually transform himself into an ordinary bat —- all possessions worn or carried will be part of the transformation —- and fly accordingly. Flying, either with the cloak or as an ordinary bat, can be accomplished only in darkness (either under the night sky or in a lightless or near-lightless environment underground). Either of the flying powers is usable for up to one hour at a time, but after a flight of any duration, the cloak will not bestow any flying power for a like period of time.

The cloak also protects the wearer from attacks. This benefit extends to the wearer even when he is in bat form.
