An ancient dwarven memory has awakened within you — older than your grove, older than your gods, and utterly hostile to undeath. When you call upon this power, the stone beneath you remembers, the air grows heavy, and the wrath of your ancestors surges through the battlefield.
As an action, you unleash ancestral power in a 30-foot cone, choosing one of the following effects:
Ancestral Rebuke. Each undead creature in the cone must make a Constitution saving throw against your spell save DC. If you do not have a spell save DC, the DC equals 8 + your proficiency bonus + your Wisdom modifier. On a failed save, a creature takes 2d8 radiant damage and is ancestrally marked until the end of your next turn. On a successful save, the creature takes half as much damage and is not marked.
Ancestral Armament. Choose any number of allied creatures in the cone. Until the end of your next turn, the first time each chosen ally hits with a weapon attack, the attack deals an extra 2d8 radiant damage. If the target is an undead creature, it is also ancestrally marked until the end of your next turn.
Ancestral Mark. An ancestrally marked creature cannot regain hit points or benefit from regeneration.
Once you use Smite of the Ancestors, you cannot use it again until you finish a long rest.
