Chromatic Explosion

You hurl a 4-inch-diameter sphere of energy at a point within range. Once it hits the ground it expands into a massive magical explosion of chromatic magic. Each creature within a 40-ft radius must make a DEX saving throw or take 3d8 acid damage, 3d8 cold damage, 3d8 fire damage, 3d8 lightning damage, 3d8 poison damage, and 3d8 thunder damage with half damage on a success. Any creature who fails their saving throw must also roll a d6 and suffer the below effect for 1 minute or until the effect is dispelled.
