Color Cloud

This spell is similar to color spray. It causes a vivid cloud of clashing colors, which cause living creatures in the area of effect (or who enter the area of effect) to become blinded or possibly even unconscious. The cloud covers an area up to 20 feet square or 20 feet in diameter, as chosen by the caster. Each creature within the cloud is affected according to its hit dice: • 4 HD or less: The creature becomes unconscious for 2d4 rounds, then is blinded for 1d4 rounds. • 5 to 8 HD: The creature is blinded for 1d4 rounds. • 9 or more HD: The creature is blinded for 1 round. All creatures having more levels or hit dice than the spell caster, or having 10 or more levels or hit dice in any case, are entitled to a save vs. Spells to negate the effect. Sightless creatures are not affected by this spell.
