Venom Expulsion

Your swarm touchs one creature and causes it to spew bee venom from its mouth, provided it has one. The creature expels the venom in a 15-foot cone. Each creature in that area must make a Dexterity saving throw, taking 2d6 damage poison damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
