Exctheis - A laser apparatus designed into the shell of a native snail-type creature to the Iilausian homeworld. The starved beast is 'fed' a controlled six (6) 'meals' of a scarab-esque bug with prismatic shells. Lenses were built into the beast's shell to magnify its excrement in the form of a concentrated burst of light. A millennia of innovation had refined the design from brutal single-use device to a symbiotic reliance; controlled evolution shaping the slug into a powerful armament of laser warfare with virtually no harm to the creature. The fuel is burnt and refracted in an instant and the next 'round' is drawn from the farthest 'port'.
- Being a living creature, rounds loaded cannot be recovered. Therefore Kaeci keeps a terrarium of literally live munitions in his quarters as to cultivate rounds for this gun...and love takes time~

'Sandcastle' PDW - 16-cap .45 'black tip' tungsten rounds. More of a sidearm, though still used in tandem with Excthesis.

Chameleon Chitin
Mimicking texture and an assortment of pigments, Kaeci's expressive flesh is covered with manipulatable cilia. The fibers are capable of retracting to the point of leaving his flesh porcelain smooth or extending to cover himself in an inverse-mirror camouflage rendering him nearly invisible, especially while holding still. Predatory defenses evolved to be capable of wrestling down larger prey, and conventional melee will find difficulty in hampering Kaeci's taught and springy structure.
Such cilia in fine and durable, able to find tiny cracks and disperse weight, allowing Kaeci to cling to walls and most ceilings, assuming they aren't sheer flat.

'Blind' Senses
Total darkness is the preferred hunting conditions for the Iilausa, sporting six eyes. While their two dominant snake-like slit pupils focus detailed images with little light, a top set on the front edges of their temples are sensitive to thermal radiation. These ink-black splotches don't so much 'see' as 'feel' and are greatly aided by the bottom two located on his cheekbones. His bottom two eyes perceive blinks of auditory refractions in the world slightly greater than 180^o.
The combined bio-thermal sensors, auditory sensors and keen minima-light vision allow his species to be efficient and discerning in total darkness.
- Chitin sheaths can close to section off these sensory organs when not in use...or to keep blood and other fluids from irritating them during feeding.

Unconventional Psuedo-Humanoid Anatomy
With adorned skins and an array of cartilage plates making up facial features, strong muscles bent their typical appearance into a form that better blended in not only with foliage but other fauna. While the Iilausa are terrible at replicating a specific human face, they find a disturbingly great amount of ease in mimicking the typical human facial structure.
The typical Iilausa has four upper appendages which neatly fit together; the bottom two sport two 'fingers' while the top possess an opposable thumb and two other 'fingers'. Pressed together, especially with long sleeves and gloves, this easily passes as any common human arm...save for having rending claws and no fingerprints.
- A psuedo-joint allows each limb to have a durable level of flexibility, serving the purpose of having essentially 4 arms.

Venom
While Kaeci and his kind possess conventional teeth, the muscular makeup of his skull has a second fold as simple as lifting an eyebrow. Dropping the façade scrunches his jaw line into a muscular maw of aligned sheaths for the four hypodermic fangs (two upper and lower) designed to deliver a potent chemical with varying effects depending on the administration quantities.
Low- A small concentration has a property which often elicits a mild euphoric sensation and epinephrine response. Prey is often weakened as to prevent this outcome, though modern times have made Iilausian 'oilers' profitable, since refined low doses milked fresh and refrigerated can invoke the same response. Coupled with watered down painkillers, the effect is far cheaper and more potent than common 'alleyway medpack equivalents'. However, most Iilausians are too proud to 'sell themselves' so cheaply, as charitable donations have often found their way into drug dens.
Standard- Most darts, arrows, infused slugs (literally slugs) and a direct bite with malice often fall under this category. The dose typically though briefly induces vomiting and vertigo, leaving the target weakened to additional physical recourse. Most animals dog-sized or smaller quickly succumb to the venom's toxicity and die in a matter of minutes due to organ failure. Common humans will suffer from the quick-acting effects for a few minutes before slowly subsiding, though it may cause liver and kidney damage while being processed.
Full- A full dose is nearly an entire day's worth of metabolism devoted to replenishing the glands. The doses work in quarters and only one quarter is regenerated over the course of the day. Ergo, once per 18 hours, an Iilausian will have built up a quantity capable of delivering such a dose. Often, the exposed subject will experience self-conceived apotheosis while the toxicity corrodes their veins and eventually causes widespread organ failure often breaching the blood-brain barrier. In their unconscious state, victims frequently experience confusion and torment from their unconscious mind bleeding into their subconscious. If internal hemorrhaging or organ failure doesn't kill the victim, they will otherwise fall to cardiac arrest.
...
Similar to low doses, most Iilausians prefer to kill with honor rather than force their victims to suffer the horrors of their own melting brain's truths...and there is more than one target that need be fell'd to support the hive.

Immunity
Iilausians are highly resistant to their own kind's poison to the point of a bite being treated more for the wound rather than the toxin which holds an effect slightly less than a low dose...at its highest dose.

Slinger
Kaeci is adept with small weapons and duel-wielding. Typically one of the first in as a stealth shock troop on ship-side invasions, his aim is keen enough to harry and distract multiple targets to later be mopped up by more specialized units.
Focusing fire could yield more effective results, though Kaeci is hardly an 'assault' unit. A few millennia capitalized on ambush and flanking tactics; no sense is fixing what isn't broken.

Semi-Assassin
Predatory in nature as a calm and slow sentient trap, all it takes is a good distraction not to know how a light is flickering a bit weirdly while running past. A quick bite on single targets and enough motivation can assuredly drag a body into recesses unseen in spite of Kaeci's otherwise slight frame.
