Blinding Breath

(Spell Compendium, p. 31)

Transmutation
Level: Sorcerer 4, Wizard 4,
Components: S,
Casting Time: 1 Swift Action
Range: Personal
Target: Your Breath Weapon
Duration: 1 round

You expel your breath weapon, which crackles with eye-splitting intensity.

This spell functions like breath flare (page 38), except that targets that fail their saving throws against your breath weapon are permanently blinded, rather than dazzled.
