Shadow Veil

This greenish, indistinct robe is designed to envelop the entire body.

A shadow veil is crafted from the essence of the undead creatures known as shadows. While wearing it, you gain a +1 deflection bonus to AC. In addition, while in shadowy areas, you are treated as if you had concealment against creatures lacking darkvision, blindsight, or some other sensory ability that does not rely on light.

Prerequisites: Craft Wondrous Item, Knowledge (religion) 5 ranks, create undead.

Cost to Create: 8,000 gp, 640 XP, 16 days.
