Prismatic Sphere (Abjuration)
Level: Mage 9, Sorcerer 9
Range: 10 feet
Casting Time: 7
Duration: 2 turns
Area of Effect: 10-foot radius sphere
Saving Throw: Special

The character conjures up an immobile, opaque globe of shimmering, multicolored light that surrounds the character and protects the character from all forms of attack. The sphere flashes in all colors of the visible spectrum, each of which has a distinct power and purpose. The sphere is immobile, and the character can pass through and remain near it without harm. Other creatures who attempt to attack the character while in the sphere or pass through the sphere itself suffer the effects of all remaining colors. Creatures with fewer than 8 HD that view the sphere are automatically blinded (see blindness/deafness) for 2D4 rounds by the colors of the sphere.

Typically, only the upper hemisphere of the globe will be visible, since the character is at the center of the sphere, so the lower half is usually excluded by the floor surface the character is standing on.

The sphere 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 sphere, but an antimagic field fails to penetrate it. Dispel magic and greater dispelling cannot dispel the sphere or anything beyond it. Magic resistance is effective against a prismatic sphere, but must be repeated for each color present. The properties of the colors are as follows:
