Prismatic Wall (Conjuration/Summoning) Level: 8 Range: 10 yds. Components: V, S Casting Time: 7 Duration: 1 turn/level Area of Effect: 4 ft./level wide x 2 ft./level high Saving Throw: Special This spell enables the wizard to conjure a vertical, opaque wall—a shimmering, multicolored plane of light that protects him from all forms of attack. The wall flashes with all colors of the visible spectrum, seven of which have a distinct power and purpose. The wall is immobile, and the spellcaster can pass through the wall without harm. However, any creature with fewer than 8 Hit Dice that is within 20 feet of the wall and does not shield its vision is blinded for 2d4 rounds by the colors. Each color in the wall has a special effect | Color | Order of Color | Effect of Color | Spell Negated By | | ------ | -------------- | ----------------------------------------------------------------------------------------- | ------------------------------------------------------------------- | | Red | 1st | Stops nonmagical missiles-20 points of damage/ Save vs spell of 1/2 | [[Cone of Cold]] | | Orange | 2nd | Stops magical missiles-40 points of damage/ Save vs spell of 1/2 | [[Gust of Wind]] | | Yellow | 3rd | Stops poisons gases, and petrification-80 points of damage/ Save vs spell of 1/2 | [[Disintegrate]] | | Green | 4th | Stops Breathe Weapons- Save vs poison or die; survivors suffer 20 points of poison damage | [[Passwall]] | | Blue | 5th | Stops location/detection and mental attacks-Save vs petification or be turned to stone | [[Magic Missile]] | | Indigo | 6th | Stops magical spells- Save vs wand or go insane | [[Spells/Magic User/2nd Level MU/Continual Light\|Continual Light]] | | Violet | 7th | Force field protection-Save vs spell or be sent to another plane | [[Spells/Magic User/3rd Level MU/Dispel Magic\|Dispel Magic]] | Each color also can be negated by a specific magical effect, but the colors must be negated in the precise order of the spectrum. The accompanying table shows the seven colors of the wall, the order in which they appear, their effects on creatures trying to attack the spellcaster, and the magic needed to negate each color. The wall’s maximum proportions are 4 feet wide per level of experience of the caster and 2 feet high per level of experience. A prismatic wall spell cast to materialize in a space occupied by a creature is disrupted and the spell is wasted. Notes: Common spell (PHB).
