These silver and red bracers are set with round, jet-black stones.

Bracers of the blast barrier allow you to turn a spell or spell-like ability into a temporary wall of magical energy. When you activate these bracers, the next spell you cast or spell-like ability you use before the end of your turn instead appears as a 10-foot-long, 10-foot-high opaque wall that lasts for 1 round per level of the spell. One end of the wall must be placed at any corner of your space, and the wall can extend in any direction. The wall must be continuous and unbroken when created. If its surface is broken by any object or creature, the wall fails to form and the spell and activation are lost.
Any creature passing through the wall takes damage equal to that normally dealt by the spell or spell-like ability (with a minimum of 1 point per level of the spell or spell-like ability). A successful Reflex save (using the normal save DC for a spell of that level cast by you) halves this damage.
This ability functions three times per day.

Prerequisites: Craft Wondrous Item, wall of fire.
Cost to Create: 1,500 gp (plus 200 gp for base item), 120 XP, 3 days.
