Breezeblade

You launch a tunderous shockwave at a target within range. Upon impact, it reverberates into a 20ft radius, dealing 12d6 thunder damage. The targeted creature must make a Strength saving throw or be knocked prone. Anyone stood in the radius, must make a Dexterity saving throw or take 12d6 thunder damage on a failure, or 6d6 on a success.

If the intial ranged spell attack misses, the spell fails.
