Survival in New Vance

Bonus Action. You slam your reinforced boot into the ground, sending a concussive shockwave outwards in a 30-foot radius. Each creature of your choice within range must make a Strength saving throw. On a failed save, a creature takes 3d8 force damage and is knocked prone. On a successful save, they take half damage and are not knocked prone. The shockwave dissipates instantly.
