Prismatic wall creates a vertical, opaque wall—a shimmering, multicolored plane of light that protects the character from all forms of attack. The wall flashes with seven colors, each of which has a distinct power and purpose. The wall is immobile, and the character can pass through and remain near the wall without harm. However, any other creature with fewer than 8 HD that is within 20 feet of the wall is blinded (see blindness/deafness) for 2d4 rounds by the colors if it looks at the wall.

The wall’s maximum proportions are 4 feet wide per caster level and 2 feet high per caster level. A prismatic wall spell cast to materialize in a space occupied by a creature is disrupted, and the spell is wasted.

Each color in the wall has a special effect. The accompanying table shows the seven colors of the wall, the order in which they appear, their effects on creatures trying to attack the character or pass through the wall, and the magic needed to negate each color.

The wall can be destroyed, color by color, in consecutive order, by various magical effects; however, the first must be brought down before the second can be affected, and so on. A rod of cancellation or a Mordenkainen’s disjunction spell destroys a prismatic wall, but an antimagic field fails to penetrate it. Dispel magic and greater dispelling cannot dispel the wall or anything beyond it. Spell resistance is effective against a prismatic wall, but the caster level check must be repeated for each color present.

Violet 	7th 	Energy field destroys all objects and 		Dispel Magic effects

The violet effect makes the special effects of the other six colors redundant, but they are included here because certain magic items can create prismatic effecs one color at a time, and SR might render some colors ineffective (see above).
