Ancient Darkness

a creature you can see within range is engulphed by darkness. The target must make a constitution saving throw or takes 2d6 necrotic damage on a fail save. The target gains no benefit from cover for this saving throw.

At Higher Levels. The spell’s damage increases by 2d6 when you reach 5th level (3d6), 11th level (4d6), and 17th level (5d6).
