Swarm

You conjure a small swarm of insects that rush towards your target and attempt to sting them. Make a ranged spell attack against the target. On a hit, it takes 1d8 piercing damage, and suffers a further 1d4 poison damage on the start of its next turn.

The spell's damage increases by 1d8 and 1d4 you reach 5th level (2d8 and 2d4), 11th level (3d8 and 3d4), and 17th level (4d8 and 4d4).
