Doom

You choose a creature within range and call for its impending doom.

The target must succeed on a Charisma saving throw or become immediately aware of its impending doom, and become Frightened for the duration. At the end of each of the target's turns, it can remake its saving throw, ending the spell on a success.

The spell's base damage is 6d8. If, at the end of your turn, the spell has not ended, the damage increases by 2d8. When the spell ends, either through the target succeeding on its saving throw, your concentration being broken, or you choosing to end it, the target's mind is flooded with calamity and takes psychic damage equal to the total amount of accumulated damage.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the base damage increases by 2d8 per level of spell slot above 5th.
