BEES!?

Swarming locusts fill a 10-foot-radius Sphere centred on a point you choose within range. The Sphere remains for the duration, and its area is Lightly Obscured and Difficult Terrain.

When the bees appear, each creature in it makes a Constitution saving throw, taking 1d12 Piercing damage on a failed save or half as much damage on a successful one. A creature also makes this save when it enters the spell’s area for the first time on a turn or ends its turn there. A creature makes this save only once per turn.
