Arbitrary Spike Serration (3.5e Maneuver)

Every time one of your attacks strikes true, spikes sprout from the weapon and mutilate the target's flesh.

Whenever you hit a creature with an attack, that creature must make a Fortitude save or take 1 point of Constitution damage. If a creature is hit multiple times in the same round, they only make one Fortitude save for all of the attacks, taking either several points of Constitution damage or none.

This stance is supernatural.
