Void Warp

You channel negative energy to harm the life force of one creature you can see within range. The target must succeed on a constitution saving throw or take 1d8 necrotic damage and subtract 1d4 from the next attack roll or ability check it makes before the end of your next turn.

This spell’s damage increases by 1d8 when you reach certain levels: 5th level (2d8), 11th level (3d8), and 17th level (4d8).
