Color spray

Color spray is a spell used by wizards that, when cast, creates a vivid cone of clashing colors which spring forth from the caster's hand or implement. Enemies hit are not only injured lightly by the sheer power of the magical light, but are also dazed into a momentary stupor. Prior to the Spellplague, the spell was more versatile and could cause creatures to become stunned, blinded, or possibly knock them unconscious. The spell was also used by sorcerers and contrary to its use afterwards, could only be cast a number of times per day that the caster had either prepared for it or had the energy left for spellcasting. After the Spellplague, the spell, while difficult enough in use to require a short rest from its caster before being used again, became usable many more times per day.
