Feat Effect: Effect: Spiral Sworn

Granted by Spiral Sworn

Your Strikes and spells deal additional damage against undead, creatures in possession of an imprisoned soul, or creatures you have witnessed create or command undead. You gain a status bonus to damage with your Strikes against these creatures equal to the number of weapon damage dice. Spells you cast from spell slots gain a status bonus to damage against these creatures equal to the rank of the spell; this bonus applies only to spells that deal damage and don't have a duration.
