Hydaelyn

You place a death curse on a creature you can see within range. The creature must make a Wisdom saving throw or begin to rapidly decay, taking 3d6 necrotic damage at the start of each of their turns and suffering disadvantage on attack rolls and ability checks. The curse can only be ended by killing or knocking out the caster, moving to a different plane, or using Remove Curse, Greater Restoration, or Wish.
