During the War Against the Darkness, the Kuni family of the Crab came to realize that the forces of the Lying Darkness were uniquely vulnerable to the power of crystal. The Kuni threw themselves into researching the ways of crystal and learning how to call on its power through the medium of the Earth kami. This prayer was the result.
A Sapphire Strike appears much like the far more well- known Jade Strike, but the blast of elemental energy which is unleashed shows a distinctive blue-green tinge, quite different from the bright green color of a Jade Strike, as the Earth kami call on the essence of Lady Sun’s tears. The Sapphire Strike has a DR of 4k4, but only against targets who are specifically vulnerable to Jade or Crystal. It is considered to be both Jade and Crystal for the purpose of game effects such as whether it penetrates Invulnerability or Reduction.
