This dull gray item appears unremarkable. Indeed, your eye easily strays from it.

A suit of armor or shield that has this property renders you and all your equipment completely imperceptible to other creatures. When you activate it, you become invisible and inaudible, and you cannot be detected by any nonmagical sensory method (including scent, hearing, tremorsense, blindsense, and the like). Once activated, this effect lasts for 3 minutes or until you attack (as defined for the purpose of the invisibility spell; PH 245).
Creatures immune to mind-affecting spells and abilities can perceive you normally.
The vanishing property functions two times per day.

Prerequisites: Craft Magic Arms and Armor, suggestion or cloud mind (EPH 84).
Cost to Create: 4,500 gp (plus 150 gp for base item), 360 XP, 9 days.
