Tōketsu-kyū is a sixth level evocation with a range of three hundred feet and a material requirement of a small crystal sphere.
Upon casting, an atom of dark energy with a negative temperature shoots from the wand. As it travels through the air, it freezes the water vapor and begins to grow. The maximum size of the ice sphere is about that of a golf ball. Once the sphere reaches the maximum range, it will dispel, but the newly formed ball of ice will continue. If cast from a high position, such as the roof of a tall building, the impact can be lethal. Serious injury can occur from any distance if shot horizontally. If shot directly up, the ice sphere will fall back to earth at around fifty-four miles per hour.
Discovered in Japan in the early 1800s, it has been used as a weapon in many wars. Referred to a ‘guerilla rain,’ it was used to pummel opposing forces and led to victory in Japan’s invasion of Taiwan and the Boxer rebellion.
Today, Tōketsu-kyū is used in testing aircraft design and scientific research. In 2013, scientists discovered that what was once thought to be the coldest possible temperature, absolute zero, was nowhere near the truth. As mentioned earlier, the spell creates an atom with a negative temperature, that is, below absolute zero. This discovery has prompted scientists to come up with a new scale of measurement and dubbed the phenomenon, quantum gas.
Tōketsu-kyū is a controlled spell in the United States which requires a permit to cast.
