Legs should follow the body shape rules–the center of mass should be further forward for quadrupedal dragons and further back for bipedal dragons. The scales of all dragons may switch to smooth scales at some point between the shoulder and claws. This smooth-scaled area may have a different color than the normal base, as long as it’s within elemental rules. If a dragon is already smooth-scaled, then it will all be one solid color (with one exception).
Amphibious Limbs

Amphibious limbs are smooth limbs with nubs for fingers. The legs are quite flexible and can end up in strange positions. They don’t have claws. They can have webbing between their toes. When drawing amphibious limbs, you can reference any living amphibian for your design.

Unlike other dragons with smooth scales, amphibious limbs will not have scutes or plating on the feet. They will never have paw pads or claws without the corresponding modifier.
Artifical Limbs

Limbs which are made of metal, clay, or some other clearly manufactured/artificial substance. You may choose to have only one limb be artificial. If you do, the other limbs will resemble one of their parents or one of their natural element (excluding mythic limbs). They must be designed for grabbing, walking, or swimming, and movement functionality. It will not have an excess of materials, things hanging off of it, decorative designs, or frivolous add-ons. You may choose to draw your dragon without artificial parts, although there will be some sort of weakness or deformity underneath them. For more info on artificial materials, look here.

Row 2: 1 – fur is not an artificial material, and faux fur is also not accepted; 2 – this is a firearm, not an actual arm; 3 – this is not designed for grabbing, walking, or swimming; 4 – this has a feature which is not practical and likely not part of the limb itself
Aquatic Limbs

Fins, flippers, or limbs adapted to aquatic life! Animals that simply hunt in the water do not count for aquatic limbs if their feet are not adapted to water. You are still limited to the amount of limbs determined by the dragon’s body type, and the limbs must be in the appropriate parts of your dragon’s body type.

Fingered Limbs

Legs with fingered feet that resemble that of lemurs, monkeys, shrews, rabbits, bats, rodents, canines, or any members of Euarchontoglires. You may include digging claws and paw pads. They must always have some sort of opposing thumb on the front limbs–this can appear in the shape of a dewclaw if needed. They will have four or five toes per foot. The front limbs should be able to grasp.
Reptilian Limbs

Reptilian legs ending in smooth, clawed, elongated toes. These toes usually have spaces in between them and will never look like paws. Lizards, birds, and dinosaurs are just a few examples you can pull from. They will always have claws. You may give them larger scales or scutes leading up to their toes. They typically point in different directions, rather than having the toes point towards a ‘center.’ You may use any reptile or bird as an example.
Here are some examples of Reptilian Limbs that don’t work:

Row Two: 1, This sea turtle fin does not show claws ; 2, While the feet are clawed and the toes are similar to alligators, there are no spaces between them and the four bottom toes point towards the center. Even though there are no paw pads, they resemble paws; 3, there are paw pads and no claws; 4, there are paw pads, no space between the toes, and the toes point inwards. they look too much like paws; 5, there are no claws. Points are not accepted as claws. ; 6, how did this even happen, it is a human hand and definitely not reptilian
Ungulate Limbs

Any sort of hooved legs from the ungulate family that are not extinct. This includes zebra, camels, rhinoceros, bison, hippopotami, horses, elephants, and pigs. This does not include whales or extinct ungulates. Below are examples of what not to do!

F.A.Q.
How do I make wolf feet/cat feet/[insert animal here]?
There are two ways to give your dragon paws. The first is to have mythic limbs, which allows lots of legs, different legs, and almost limitless possibilities for your limbs. The second method, and by far the easiest, is to acquire the Brawn trait. This rare Earth trait can give your dragon the feet of any land-based animal you can think of.
Can I make mis-matched legs?
If your feet are within the same type of leg (such as a sea turtle and a bird both being reptilian), then you may mix them without any extra stuff. Mythic limbs allow mis-matched legs. Brawn allows you to mix in pairs–which means the front can be bird-like, and the back can be paws–similar to a gryphon!
