This wristband seethes with ever-shifting shadows. Its touch feels like frozen silk.

Actually a small rift between the Plane of Shadow and the Material Plane, a shadow maniple allows characters adept at shadow magic to derive healing from their use of such magic.
When you cast a spell with the shadow descriptor, or whenever you cast a mystery (see the shadowcaster class, ToM 111), you can activate the maniple to heal damage equal to the level of the spell or mystery.
A shadow maniple functions three times per day.

Prerequisites: Craft Wondrous Item, shadow conjuration or any apprentice mystery.
Cost to Create: 1,500 gp (plus 700 gp for base item), 120 XP, 3 days.
