A brilliant explosion occurs where you direct, causing 1d6 points of magic damage per caster level (to a maximum of 25d6) to all undead. Non-undead creatures suffer only 6d6 points of magic damage. Vampires are destroyed instantly if they fail a Reflex saving throw. All enemies in the area of effect must also make a successful Reflex saving throw or be blinded.
The description is somewhat misleading. The reflex save is NOT partial. It works like this:
If save is failed: Vampires are destroyed, all other enemies take full damage based on metamagic feats/racial type (enemies with Improved Evasion take half damage) and are permanently blinded.
If save is successful: All enemies including vampires take half damage (enemies with Evasion/Improved Evasion take no damage). No blindness if save successful.
Vampires are not really destroyed. Technically, the game tries to reduce their hit points to 0. This is extremely imprecise and the vampire may actually survive even if they fail the saving throw. It would have been better to apply the death effect to them, bypassing death immunity in the process.
