Ice Release: Lunar Jewel

After weaving the needed hand signals, the user creates a large ball of ice around the target and manipulates air currents to lift them high into the air. Then, the user causes the ice sphere to implode, covering the target in ice all over. Usually, this technique results in the inflicted target instantly freezing to death. However, if the user wants, the ice structure insulates itself to allow the target to live, but remain too cold move properly. The outside of the structure is also very hard, and nearly impossible to penetrate.
