Corailkinesis is the biological ability of a DNA Alternate to form and reform calcium carbonate composed coral skeletons. These skeletons can be those found naturally, or are self generated. Calcium is taken directly from the Alternate's bones and secreted as a lime compound from the pores of the skin, thus granting the Alternate a coral layering. This also means, however, that the Alternate must remain in close proximity to the coral whilst constructing.
These coral constructs can be molded into a variety of tools, defensive shields, weapons, or constructs. In addition, stinging cells known as cnidocytes may be developed among the structures forged. Cnidocytes generated by the Alternate will usually be of a set strength. The cnidocytes gained from the manipulation of a real coral will vary in potency depending on the coral type.
While the self-generated version may be a handy alternative to utilising those formed naturally, it is imperfect and not as durable as true coral. This is due to the lack of zooxanthella in the fake variety. As such, the skeleton formed from the Alternate is pre-bleached and needs a constant calcium supply from the user of this ability to make up energy requirements. Without enough energy the generated coral will weaken in strength and fracture more readily.
Use of the bones as the main energy source is also non-preferred for a secondary reason. It depletes the body of its calcium. Overuse of the ability, and without regular calcium top-ups, can lead to brittle bones, and even osteoporosis. Immediate affects of overexploitation include muscle pains, listlessness and convulsions, in extreme cases of a deficiency.
