Ancient Oath

You bind a creature’s blood to an ancient vow.

The target must make a Constitution saving throw. On a failure, it is bound by a blood oath:

• Choose one condition:

  • Hunt: The target has disadvantage on attack rolls against creatures other than you.

  • Guard: The target has disadvantage on attack rolls against a creature you designate.

  • Obey: The target has disadvantage on saving throws against being frightened or charmed by you.

• Once per turn, when the bound creature violates the oath’s intent, it takes 4d10 necrotic damage (no action required).

• This damage cannot reduce the creature below 1 hit point.

On a successful save, the spell fails with no effect.

Creatures immune to being charmed have advantage on the saving throw.
