Editing Periodic Table of Dragons/Rules and World Description (section)

===Alloys and Breeding===
*Alloys can be produced through breeding
**Alloys will not breed true, instead producing one of the elements present in the mating, use Mendelian genetics square
*A dragon can eat another dragon or dragon's scales to gain an alloy's properties, but this is temporary
**More mass consumed = longer duration
**A dragon can eat a born-Alloy or a Pure and gain its properties, but can only 'hold' three elements including their own. Ex: Iron eats Chromium and Carbon, they become stainless steel, but eating another dragon will cause the oldest of the previous elements to "drop".
***Some Alloys cannot be done (Au+any Hg-containing alloy for example) and result in either weakening or death. 
***Elements that do not react will not form an alloy.
**Eating the scales or body of a dragon that ate another dragon will only confer the original element, not the element of the dragon they ate.

*Combinations of Metallic and Fluid dragons never end well, because the two species are incompatible. The Metallic dragons burn the Fluid dragons, and the Fluid dragons cool and shatter the Metallics. This is to prevent having to describe the insanely huge range of chemical compounds that might result, and keep the narrative focused on the Elemental Dragons, not their hybrids.

*Fluids cannot eat each other to make compounds because their blood evaporates once outside their bodies, leaving no element for the other dragon to absorb. Also, few Fluids possess teeth strong enough to penetrate flesh.
*Fluids can crossbreed, but the hybrids are universally sterile.
