Doom

You focus on a creature within range to inflict them with impending doom. The target must succeed on a Wisdom saving throw or take 1d4 necrotic damage and becomes frightened of you until the end of your next turn. If the target is already frightened, it takes 1d10 necrotic damage. Any creature that can't be frightened succeeds on this saving throw automatically.

The spell's damage increases by one die when you reach 5th level (2d4 or 2d10), 11th level (3d4 or 3d10), and 17th level (4d4 or 4d10).
