You momentarily flood the mind of an in-range creature you can see with visions of many possible immediate futures, each ending in pain, death, or failure for the target should they make the wrong choice of action.  The sensation is fleeting and leaves no memories, but the target must make a Wisdom saving throw or suffer 1d8 psychic damage.  Regardless of the save outcome, the target cannot take reactions until the end of their next turn.

The spell's damage increases by 1d8 when you reach 5th (2d8), 11th (3d8), and 17th (4d8) level.
