Razorfangs - Dragon

Wizard's Spell Compendium Version

This spell is a highly improved version of the sharptooth spell. When a razorfangs spell is cast, the dragon's teeth become exceptionally hard, strong, and sharp.

Due to this alteration, any successful bite attack inflicts +2 per age category to each damage roll.

Furthermore, on an unmodified roll of 19 or 20, the bite severs an opponent's limb (or other extremity, as appropriate), just as if the victim had been struck with a sword of sharpness.

If the victim fails a saving throw vs. death magic, his head is severed as if by a vorpal sword. The razorfangs spell is useless to a non-dragon.
