Geologic overrides the dergon's entire design, instead letting them mimic the patterning of any mineral (including cut stones, natural rock, metals, and extraterrestrial bodies). The design does not have to be an exact replica, but color and pattern inspiration should be clearly visible! You can include a link to an example of your chosen mineral when submitting a geologic design for approval, and it may optionally be linked in your import description.

You may still include your dergon's original genotype in the choice of inspiration, for example, such as choosing to mimic an agate when your geno has Bloom, Halo, and Ribbon. You can also use Geologic to influence an otherwise normal design, for example taking a Ginger with Banding geno and adding multicolored echoes of the banding by choosing sandstone as your inspiration. 

Geologic may affect your entire dergon. If you choose to include your original geno, Geologic must affect at least 50% of your design. 

When present with a color mutation, Geologic may do one of three things:

• Completely override the color mutation

• Allow the color mutation to affect the design, influencing features you're taking inspiration from

• Take inspiration from a mineral which resembles the color mutation

The third option includes, as an example, things like howlite for Dilute, or snowflake obsidian for Variegation.

When present with another mutation such as Chimera, Geologic may either override the chimeric design or take inspiration from a mineral with two parts, such as inclusions or native gold on quartz. 

Strange Covering may be influenced by Geologic, creating scales, armor, or fins that mimic the chosen inspiration. Mild can affect up to 20% of the dergon, Moderate up to 60% and Severe up to 100%.
