Prismatic Barrier

Description

You create an immobile and opaque barrier of multicolored light (radiates normal light within 20 sq and dim light within 40 sq). It must be continuous and unbroken when formed. The wall actually consists of seven separate layers, each with its own protective power, damaging effect, and vulnerability. Effects and objects passing through the barrier are automatically stopped if the appropriate layer is still active. Creatures other than you that try to pass through the barrier suffer the damaging effects of all active layers. Each layer can be automatically negated by the vulnerabilities listed below, but the layers have to be removed in the indicated order.\nOrder and color: Protection; Damaging effect; Vulnerability\n1 - Red: Nonmagical ranged weapons; +20 vs Ref (40 or 20 HP of fire damage); Extreme cold\n2 - Orange: Magical ranged weapons; +20 vs Ref (60 or 30 HP of acid damage); Extreme wind\n3 - Yellow: Poison, gas, and petrification; +20 vs Ref (100 or 50 HP of electricity damage); Disintegrate\n4 - Green: Breath weapons; +20 vs Fort (poison - 3d6 or 1d6 Con damage); Phase door\n5 - Blue: Divination and mental attacks; +20 vs Fort (petrification); Force damage\n6 - Indigo: All supernatural attacks; +20 vs Will (insanity); Bright light\n7 - Violet: All objects and effects; +20 vs Will (sent to another plane); Antimagic
