Thunderdrop

With a downwards motion of your hand, you magically create a nauseating low-frequency noise. All creatures within 40 feet of you must make a constitution saving throw, taking 4d10 thunder damage on a failed save, or half as much on a successful one. Any creature that fails the saving throw is poisoned until the end of their next turn.

When you cast this spell using a spell slot of 4th Level or higher, the damage increases by 1d10 for each slot level above 3rd.
