Necromancy [Death, Evil]
Level: Cleric 8, Abyss (SpC) 8,
Components: V, S, AF,
Casting Time: 1 Standard Action
Range: 30 ft
Target: One living creature
Saving Throw: Fortitude negates

You invoke the powers of deep darkness and your eyes vanish, looking like holes in the universe itself.
Upon completion of the spell, you target a creature within range that can see you. That creature dies instantly unless it succeeds on a Fortitude save. The target need not meet your gaze.
If you slay a humanoid creature with this attack, 24 hours later it transforms into a bodak (MM 28) unless it has been resurrected in the meantime. The bodak is not under your command, but can be controlled as normal with a rebuke undead check.
Focus: A black onyx gem worth at least 500 gp.
