Bracers of Defenselessness

These appear to be bracers of armor +5 and actually serve as such until the wearer is attacked in anger by an enemy with a Challenge Rating equal to or greater than her level. At that moment and thereafter, the bracers cause a ⁠—​5 penalty to AC. Once their curse is activated, bracers of defenselessness can be removed only by means of a remove curse spell.

Prerequisites: Craft Wondrous Item, mage armor, bestow curse.

Cost to Create: 600 gp, 48 XP, 2 days.
