Deafening Thunderstrike

You slam your weapon into the ground, creating a thunderous explosion in a 20-foot radius around you. Each creature in the area must make a Constitution saving throw. On a failed save, a creature takes 6d6 thunder damage, is pushed 10 feet away from you, is knocked prone, and is deafened for 1 minute. On a successful save, the creature takes half damage and is not pushed, knocked prone, or deafened.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the thunder damage increases by 1d6 for each slot level above 5th. Additionally, the radius of the explosion increases by 5 feet for each slot level above 5th.
