Arcane Detonation

You hurl a volatile orb of unstable arcane energy to a point you can see within range. The orb detonates with a concussive roar, sending shockwaves rippling through the battlefield.

Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A creature takes 5d8 force damage and 2d6 thunder damage on a failed save, or half as much damage on a successful one.

Creatures that fail the saving throw are also pushed 10 feet away from the center of the blast. In addition, they must succeed on a Strength saving throw or be knocked prone.

The blast leaves a faint distortion in the air until the end of your next turn, shimmering with residual magic.
