The Claduhan grow between the heights of 91cm and 127cm, weighing around 50 pounds once fully mature. However, female goblins are able to reach heights as tall as 157cm and could weigh up to 114 pounds or 90 pounds at the least. Overall, their body types tend to be relatively squat while maintaining a nimble physique. Their ears often take the shape of various leaves depending on a Claduhan's home environment, growing as long as 8 inches with a minimum length of 4 inches. Claduhan experience sexual dimorphism, where females tend to be physically larger than males. However, this does not mean either is stronger than the other, as both present similar levels of physical strength. It is also said that female Claduhan have brighter colorations than males, but this tends to be too subtle to be fully proven. Their life spans are the shortest of the Wyrdborn, ranging from 40-60 years. The oldest recorded Claduhan dying of natural causes was 60.

Both their skin and hair colors vary based on their surroundings, working as a biological camouflage to blend in with nature. These can range from sandy browns to vibrant greens, with skin sometimes marbling with darker-colored markings to match the patterning of their environment. Eye colors tend to follow similar trends, coming in forms of yellows, oranges, browns, greens, and even white. It also isn’t rare for sclera to be oddly colored in the same manner, most commonly being black or orange respectively. Due to the chaotic nature of The Claduhan's fey ancestry, these colorations have the chance to shift based on temperature during adolescence. For example, if a Claduhan was born with green hues but was then raised in a hot and arid biome, they might present themselves with colors that resemble sand or clay.

While the Claduhan are possibly the most humanoid of all fey-descended races on the material plane, they host a handful of arachnidian features leftover from their ancestry, although these tend to be very subtle and are hard to recognize at first glance. Most have small microhairs across their legs and arms that are able to feel air movements and vibrations, making them hypersensitive to their surroundings, including potential threats and environmental hazards. This tends to make them very antsy, becoming a common occurrence for them to be unable to sit still for long periods of time or to overreact in certain situations. To prevent this in more urban areas, some tend to find ways to cover or remove these hairs, while others try to embrace it at the expense of reputation.

Sharp teeth are common among all Claduhan, designed to rip through prey in an efficient manner. Fangs are also present along the canines, their length rivaling that of beastfolk. Usually, this creates a slight overbite, making their teeth poke out from their mouth while resting. Along with fangs, some Claduhan are born with the ability to inject venom with their bites, although this tends to be slightly more common in females. The toxins from this venom are not lethal, but can serve to slightly paralyze as to provide an edge in combat. Claduhan have sharp, curled tarsal claws on their hands and feet that are composed of thick chitin, made for to easily hook themselves onto tree trunks and dig into the floor for hunting purposes. This also offers the ability to create small burrows within large trees or soft ground, usually serving as a temporary means of shelter.
