Shadowsilk Cape

This cape is made out of Shadowsilk, and is thus hardly corporeal and invisible in areas of light.
*The cape contains a bound medium shadow elemental. The elemental crean reach its two shadowy arms out of the cape to attack creatures behind or on either side of the wearer. It can also make a disarm attempt at any adjacent opponent using its base attack modifier with a +4 bonus. If the attempt succeeds, it can fling the weapon in any direction up to 10 feet. 
*Whenever you cast a mystery, you heal damage equal to the level of the mystery.
*On command, the cape becomes a pair of incorporeal bat wings (loosing its attack and disarm ability in the process). You can fly at 60 ft. with perfect manuverability.
