New variants of mutaplasmid either randomizes or gives player agency to alter color values of an unlicensed ship skin token you pair with it. Already licensed (applied to character) skins cannot be modified.
Process consumes existing ship skin token and gives either a 30-day, 90-day, or permanent variant. Lower level Mutaplasmids only allow for color ‘randomization’ that CCP defines. Higher level mutaplasmids open up color controls to players and have stronger chance to produce permanent skin licenses.
When applied, abyssal modified skins overwrite existing skin license per their category, but may be changed back if player applies a vanilla skin license.
