This plain gray mantle shields your faith, alignment, and patron deity from magical detection as long as it is worn. It does not provide any bonuses to skill checks used to disguise or lie about your faith and beliefs.
Prerequisites: Craft Wondrous Item, undetectable alignment.
Cost to Create: 7,500 gp, 600 XP, 15 days.
Source: Frostburn, page 111. This seems way overpriced; calculations for a continual use item with a 2nd-level spell that has a 24-hour or longer duration by a 3rd-level cleric suggests a market price of 2 × 3 × 2,000 / 2 or 6,000 gp.
