Shatter Undead

With a powerful strike, you are able to crush undead to rubble. With a mighty crash a skeleton shatters into powder, or with a thunderous thrust, you can reduce a vampire to a bleeding pulp.

Prerequisite(s): 4th-level fighter

Benefit: Whenever you make an attack roll against an undead creature, if you roll a natural 20, and you have three hit dice more than the creature, then the creature is automatically destroyed.
