This orange silk veil can be worn as a sash, a belt, or a short skirt knotted at one hip.

Wearing a caustic veil gives you immunity to the orange effect of any prismatic spell. This is a continuous effect and requires no activation.
When you activate a caustic veil, it deals 2d6 points of acid damage to a single creature that has already taken acid damage from an arcane spell you cast in this round. This functions three times per day.

Prerequisites: Craft Wondrous Item, Melf’s acid arrow, possession of a piece of the set.
Cost to Create: 1,000 gp, 80 XP, 2 days.
