Luma's body is made up of a tiny ball-shaped semi-hollow superconductor core that spins at incredible speeds. Around it, a fine crystal lattice is formed into complex webbed structures resembling that of neurons in a brain surround the core giving the creature minimum physical structure. These details however are hidden from the naked eye due to a large mass of black plasma held together by perfectly balanced and complex magnetic fields that cancel each other out beyond the surface of her body creating an incredibly dense ball of plasma of which the plasma itself is considered a major component of the creature's actual body.

The body of a starwisp is incredibly hot plasma. In Luma's case, the plasma appears to be mostly white like typical plasma giving off full-spectrum light except for dangerous UV colours, though Luma can shift her glow to any colors desired including infrared to warm others.

Even without the shell, Luma has a field just above the surface of her plasma that pushes against anything too close, the power of which ramps up the closer the object gets, like the effect one feels when pushing two magnets of the same pole towards each other. This effect is strong enough to prevent casual attempts of creatures touching her incredibly hot plasma body, deflect rain and snow, and even push water away making a bubble at very shallow depths. If one were to attempt to touch Luma, they would feel an electrical tingling sensation push against their hand.

With the shell in place, a person can simply grab onto the shell safely though would feel a slight tingly sensation. But even without the shell a person could technically pick up Luma's plasma body by doing a scooping motion with both hands in which the body would naturally float above their hands by repulsion. Any attempt to grab however would just push Luma and/or the person's hand away. An aggressive attempt to grab or puncture may cause moderate to severe burns, or even incineration if the person penetrates deep enough to touch the plasma within as although the surface of the plasma is safe, the plasma itself is incredibly hot. This too will hurt the starwisp.

The outermost plasma is cool-plasma starting around 11,000F (6,093C) and slowly increases in temperature closer towards the core in the center. In the absolute middle of the core in an incredibly tiny space the plasma skyrockets to an insane temperature of 179,999,540F (99,999,726C) which is hotter than even the core of the sun in which particle fusion takes place. This is the primary energy source of the starwisp, making the creature a living fusion reactor. However, the actual usable energy output is limited as a large portion of the yield of energy is used to power the incredible electromagnetic forces that hold the starwisp's body together and allow it to move around.

Surrounding their plasma body is typically a protective crystal shell completely encasing and protecting her body from the outside elements. The shell appears to be considered part of the body like an exoskeleton that can be disassembled and reassembled from its base rhombus diamond shaped facets at any time. Typically they only shift a small number of facets out of the way if they need to expose their plasma body for a task.

The shell is made mostly out of silicate (glass), and other trace elements. By itself the crystal material is translucent with a subtle iridescent effect. At will the starwisp can create more of this material assuming the raw materials are available such as sand. This is normally to replace damaged facets of the shell but has been proven to have more practical uses in the glass and crystal work trade. (see paranormal ability: crystal crafting)

When needed, white wispy tendrils reach out from Luma's body, even directly through the shell when manipulating large or heavy objects. The tendrils are often compared to looking like the tendrils of light found in plasma globes that skitter across the surface of the globe.

Tendrils appear to be insubstantial besides giving a slight electrical tingling sensation to those touching them. If something physically intercepts a tendril the far side of the tendril vanishes, dropping whatever was being manipulated. Luma's tendrils have been seen to reach as far as 15 feet when focused, but normally only reach 10 feet.

To those with hyperspectral vision, can sense electrical and/or electromagnetic fields, or other special forms of vision, a second form of tendrils can be found. These tendrils that are invisible to the normal naked eye are countless and hair-thin, reaching out in all directions from the starwisp's body. These tendrils like the larger visible versions skitter across all surfaces very quickly serving multiple purposes.

The main purpose, propulsion, these tendrils pull and push against surfaces giving the impression the starwisp is floating but in reality, is pushing off of the ground or grappling onto walls and other objects to hold themself up. The weight is so widely distributed that even snow isn't disturbed. However, very fine dust may reveal strange patterns when Luma passes over it. As such Luma doesn't truly fly. Without anything nearby to climb the starwisp can't fly any higher than 15 feet from the ground.

The second purpose is providing the starwisp a sense of feel around themself, helping keep track of the physical world and surroundings.

The last purpose of these tendrils is that these are what create the starwisp's telekinetic field. Allowing them to lift objects, orbit objects around their body, or orbit their own body around other objects and people. The visible large tendrils are actually dense versions of these tendrils when they need to pack close together to lift an object with a small surface area or done intentionally for the benefit of others seeing where she is reaching. This also plays a major part in making Luma's illusions appear to be solid. (see supernatural abilities: Holographic illusions)

The drakkat form appears to be artificial, as the fur is fake, and the bones are hollow and made out of some kind of crystal material.

The breathing and heartbeat are faked, as there are no such organs, and the body is wired up with hidden fibre cables acting like nerves throughout the body.

Hidden in the chest cavity of the fake creature a 6 inch tall egg-shaped crystal shell slotted into a space designed for it. Within the shell white living plasma is the true creature making the artificial creature rig move and speak. (See Starwisp description)

The feline form is actually a magical rig. The body is living flesh and blood, but was magically created, and the body has no mind without it's pilot.

The organs of the body are slightly rearranged in which the chest can magically open up to reveal a magical pocket roughly the 10 inches in size in which a starwisp body can slot itself in to control the body. While slotted in, the starwisp sees and feels everything from the body while in it. This rig owned by Luma.
