Material: alchemized crystal powder, standard yorik-kul seed
Description:
Developing a fascination with Yuuzhan Vong biots, and wishing to impress her master, Darth Arcanix decided to begin a pet project to develop a brand new surge coral seed but with a unique twist. Through painstaking research, trial and error, and plenty of frustration, Arcanix was able to produce something that would help in later plans of hers.
The Yorik-Kryst was the cusp of this research, a surge coral seed that was changed through both science and Sith alchemy. Implanting herself with a coral seed to access Vongsense, Arcanix began a two-prong approach to the project. Using her knowledge of Sith alchemy, Arcanix created a special powered out of crushed crystals that would imbue the crystals with the ability to withstand multiple hits from a lightsaber and began the process of trying to introduce and bond the crystal powder with the surge coral seed and the implanters that carried them. Using her new Vongsense, Arcanix was able to coax the seeds to accept the powder after much trial and error and failed experiments.
The new seed works almost exactly like a normal Yorik-Kul, but instead of coral, it produces crystals that eventually form a suit of crystal armor over a subject's body, an armor that can take three to four hits from a lightsaber without breaking or multiple blaster bolts, while also crystallizing their insides as well. Only one in ten subjects survive this, and those that do are simple thralls to the will of a strong enough Sith or Vong, with no true sentience left.
The seed also does not remove a subject's presence in the Force, just dampening it as like with Chazrach slaves, leaving whoever is embedded with one susceptible to Force attacks. The crystals are also susceptible to an attack that smashes, such as a hammer or blunt force, but will eventually regrow if given enough time.
One other drawback of the seed, a rather serious one, is, like orbalisks and other surge coral seeds, the Yorik-Kryst will eventually consume and kill the being that was implanted with it, turning them into a crystal statue as the crystals grow over their faces and change their insides. This is unavoidable and inevitable for anyone implanted with one
