A modifier that causes the entire dragon to sheen like metal. It will not add extra colors to the dragon. The sheen will simply be a lighter color of what lays directly beneath it. It affects the entire dragon and accents all muscles and features.
Sheen does not change the color of the dragon. It may increase their vibrancy to a small extent, as seen in the example below.
Modifier, Claw, Leather, and Crest Rules
This affects every single trait of a dragon.
You may have the sheen affect as low as 25% of the dragon, rather than the entire dragon.
