Call the Voidling

You briefly summon a writhing, screaming mass of fleshy muscle, tendrils, and spines that lashes around wildly, attacking any living creature in reach before vanishing with a gurgling pop. Choose one or two creatures you can see within range. If you choose two, they must be within 5 feet of each other. A target must succeed on a Dexterity saving throw or take 1d6 piercing damage.

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