Bee-ware the Sting

You conjure a swarm of bees that darts toward a creature in range. Make a melee spell attack against the target. On a hit, the target takes 1d6 piercing damage from the combined stings of the bees. Additionally, the target must succeed on a DC 10 Constitution saving throw or suffer from a mild allergic reaction for 1 minute. While suffering from this reaction, the target has disadvantage on the next attack roll they make.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6) to account for larger swarms.
