Your ancestral ties to the Outer Planes manifests as an ability to deal damage with your natural attacks as if they matched the alignment of your ancestors.
Prerequisite: Anarchic Heritage, Axiomatic Heritage, Celestial Heritage, or Fiendish Heritage.
Benefit: Your unarmed attacks and natural weapons (but not the weapons you wield) are treated as having an alignment for the purpose of overcoming damage reduction. The alignment depends on the heritage feat you used to qualify for this feat: chaotic (Anarchic Heritage), evil (Fiendish Heritage), good (Celestial Heritage), or lawful (Axiomatic Heritage).
