Bee Swarm

You conjure a furious swarm of ethereal bees from your fingertips within range that lasts for the duration.  When you cast the spell, you can make a melee spell attack against a creature within 5 feet of the swarm.  On a hit, the target takes poison damage equal to 1d8 + your spellcasting ability modifier and must make a Constitution saving throw.  On a failed save, it is also poisoned until the end of your next turn.

At the end of your subsequent turns, the swarm flies up to 30 feet to the nearest hostile creature and repeats the attack against a creature within 5 feet of it.  The swarm can be targeted by an attack, has the same hit points as 5 multiplied by your spell attack modifier, and a score of 10 for all ability scores and AC.

If there are no more hostile targets that you are aware of or the swarm flies further than within 60 feet of you, you lose control of the bees and they begin attacking the nearest creature that they can see.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every slot level above 2nd.  In addition, when you cast this spell every two slot levels above the 2nd, increase the swarm's ability scores, AC, and hit point multiplier (from 5) by 2.
