Destructive Wave

5th-level evocation
Casting Time: 1 action
Range: Self (30-foot radius)
Components: V
Duration: Instantaneous
You strike the ground, creating a burst of divine energy that ripples outward from you. Each creature you choose within 30 feet of you must succeed on a Constitution saving throw or take 5d6 thunder damage, as well as 5d6 radiant or necrotic damage (your choice), and be knocked prone. A creature that succeeds on its saving throw takes half as much damage and isn’t knocked prone.
