Feat: Angel of Vindication
Requirements Your mark is an undead creature.
To aid with your mission of destroying undead, you've specialized in techniques to destroy them, much as other assassins learn to kill the living. When you Strike an Off Guard undead foe with a weapon that has the backstabber weapon trait, you deal 3 extra precision damage instead of 1. If the weapon is a +3 weapon, you deal 6 extra precision damage instead of 2. If you have the Angel of Death feat, your attacks also instantly destroy undead at 0 Hit Points, and attempts for the undead to rejuvenate-such as via a lich's soul cage or a ghost's rejuvenation ability-fail unless the effect's counteract rank is higher than half your level when you killed the creature (rounded up), or originates from an artifact or deity. Finally, if you have the Assassinate feat and an undead mark critically fails its save against your Assassinate, it is destroyed.
