Booming Sleep

A Loud Sound Booms at a point you choose within range and then blasts into a cacophony of horrible music. Each creature in a 20-foot-radius sphere centered on that point must make a Charisma Saving Throw. The spell rolls 2d100. A target will be knocked unconscious if this exceeds their current hit points on a failed save; on a successful save, the target will take a level of exhaustion if their current hit points are less than half of the total number rolled. 

"They just keep saying random words and then this NOISE goes off, like.........."

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the roll increases by 1d100 for each slot level above 5th.
