Doomsay

You assault the mind of a creature within range with a string of unsettling words that spell their doom. The spell fails if the target cannot speak a language.

The next time the target takes damage before the beginning of its next turn, it takes an additional 1d10 psychic damage. The spell then ends.

The spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
