Balthazar's Stunning Blast

You drink a shot, suck a lime wedge, and throw salt in three 10 ft. cubes within range. Each creature in the cubes must make a Constitution saving throw, taking 3d8 force damage and are stunned for the spells duration. Creatures take half as much on a successful save and are not stunned. A stunned creature may make a save to remove the stunned effect at the end of each of its turns.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d8 for each slot level above 3rd.
