Can only be one ridge along the back spine, not two (ie it can only run along the back spine once in a straight line, and not two parallel lines of spines).
Can be either: pointed horn-like spines, fish spines, fish fins, dinosaur, or lizard fins/spines
Fins can be semi-transparent, or tattered
Spines must be solid unless affected by another trait
Can extend down to tail from base of neck.
Cannot be a different texture than it's original reference (ie: fish spines have fish spine texture)
Cannot exceed more than 50% of your Stygian's body size when combined.
Cannot be taller than 50% of the Stygian's heights (from bottom of foot to back).
REGULAR STYGIAN BODY LENGTH
The BODY LENGTH of a regular stygian is measured from their chest (without fluff) to where their butt is.
Tails, extra acessories, etc, are not counted into the length of the body. When a trait says 100% of body/ body length, it would be 100% the body length (direction of the arrows from beginning to end) marked in red.
Miniature versions follow the same rules, just with miniature sizing (ie using the body length of that miniature)
LONG BODIED STYGIAN BODY LENGTH
The BODY LENGTH of a regular stygian is measured from their chest (without fluff) to where their butt is.
Long bodied Stygian have much longer bodies than regular ones. When measuring the length of a long bodyied stygian body, take the body length of the REGULAR Stygian above and multiple it by 1.5 to 2x the length
Tails, extra acessories, etc, are not counted into the length of the body. When a trait says 100% of body/ body length, it would be 100% the body length (direction of the arrows from beginning to end) marked in red.
Miniature versions follow the same rules, just with miniature sizing (ie using the body length of that miniature)
BIPEDAL STYGIAN BODY LENGTH
The BODY LENGTH of a bipedal Stygian subspecies (ie Grendel, Page, Sylph) is measured from the top of their head to their toes.
Bipedal Stygian do not include Stygian that "stand" or "pose" on their hind legs (ie regular stygian posing that way) and must be considered a bipedal subspecies that stands on their hind legs in the subspecies infograph (see subspecies info).
Hair, head additions, tails, extra acessories, etc, are not counted into the length of the body. When a trait says 100% of body/ body length, it would be 100% the body length (direction of the arrows from beginning to end) marked in red.
For object head, it would be the approximate length of where the Stygian's regular non object head would be.
Miniature versions follow the same rules, just with miniature sizing (ie using the body length of that miniature)
TREATLING BODY LENGTH
The BODY LENGTH of a Treatling subspecies (ALL) is measured from the top of their head to their toes.
Hair, head additions, tails, extra acessories, etc, are not counted into the length of the body. When a trait says 100% of body/ body length, it would be 100% the body length (direction of the arrows from beginning to end) marked in red.
For object head, it would be the approximate length of where the Treatling's regular non object head would be.
