Crushed Rock Convert to Cement

User rapidly gathers up the dust from the level ground jackhammer stamp with fast-moving hands that shape the debris like clay being squeezed between their fingers. They then surge forward and whirl around opponent, doing a variation of Raised Frame Containment, only now laying out bricks that are peppered with smaller rocks and mortared together with fused concrete. Within seconds the user effectively walls in opponent within a very narrow chimney-shaped container, fusing it solid with a burst of Chi that flows across their fingers.
