Somatic creates a patch that covers about half of the dragon. It may be one solid patch, or it can be interspersed like a merle or patchy pattern. The edges may be solid, textured, or a gradient. This patch lays on the bottom of all markings. It can be any color within elemental rules. Markings on top of it also change color according to elemental rules. It must have a hard edge.
It must follow elemental color rules. Display traits on top will change color where they touch. The display traits must stay within elemental rules unless they are affected by a modifier that affects color.
Modifier & Physical Trait Interactions
This will affect the color of all modifiers and markings that it touches. You may use color modifiers on it, but markings on top will still follow elemental color rules. All effects will only affect the bottom layer of Somatic.
Charged Somatic allows you to change the position of markings along with their color. This creates the illusion of a physical chimera (or a combination of two completely different marking/color designs).
