Nether Streak

You hurl a blindingly fast bolt of void energy at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 psychic damage. Damage is reduced by the target creature's Wisdom modifier.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
