Matter Collapse

Choose one non-Artifact object or structure section within range no larger than a 20-ft. cube. It must make a structural save using its creator’s bonus if magical, or automatically fails if mundane and unattended. On a failure, it collapses into harmless edible fragments. Creatures in contact with it must make a DEX save, taking 66 (12d10) bludgeoning damage on a failed save, or half on a success.
