Dark purple like a day-old bruise, this veil is far heavier than any gauze of silk should be.

Wearing a veil of doors gives you immunity to the violet effect of any prismatic spell. This is a continuous effect and requires no activation.
When you activate a veil of doors, it magically dismisses (as the dismissal spell; Will DC 27 minus creature’s HD negates) a single extraplanar creature within 30 feet of you that was damaged in this round by a creature you summoned or called with an arcane conjuration spell. This ability functions two times per day.

Prerequisites: Craft Wondrous Item, dismissal, possession of a piece of the set.
Cost to Create: 5,500 gp, 440 XP, 11 days.
