Gremlins are fey spirits intimately tied to technological malfunctions. One variety of gremlin, called glitch gremlins, is especially common (and feared) in societies with advanced technology. Both computer glitch gremlins and ship glitch gremlins demonstrate remarkable single-mindedness in their pursuit of mayhem as they find new and more frustrating ways to make technology break, glitch, or fail.

A computer glitch gremlin’s appearance varies widely with the digital data it has eaten, but they average 1 foot in height and weigh around 4 pounds. Ship glitch gremlins have lamprey-like mouths and long, spidery arms and legs. They stand 2-1/2 feet tall and weigh approximately 20 pounds.

Special Abilities

Amplified Radiation Aura (Su) A vaigruuk’s long, dangling ears act as radiation amplifiers. It emits low radiation within 20 feet, which it amplifies from harmless background radiation in the area. When within an area of low radiation, the vaigruuk emits medium radiation. In any environment where there is absolutely no radiation at all, such as certain shielded chambers, this aura doesn’t function. The vaigruuk can suppress its aura by wrapping its ears tightly around its body as a move action, but it is flat-footed during this time. Unwrapping its ears is another move action.
Caustic Glob (Ex) As a ranged attack that targets EAC, a vaigruuk can spit a glob of nauseating poison at a single creature within 30 feet. The acid damage from this glob results from vapors that eat away at a creature’s tissues and sinuses like a fast-acting toxin; creatures immune to poison take no damage from the vaigruuk’s caustic glob.
Despoiling Touch (Su) When a vaigruuk touches ordinary food in a container no larger than itself, the food becomes rancid and loses all nutritional value.
Irradiating Lights (Su) The illumination a vaigruuk creates with its dancing lights spell-like ability emits low radiation within the area of their illumination (which is 10 feet for dancing lights) and is always a sickly green color.


Vaigruuks are hunched, long-eared gremlins that love to skulk around and sicken creatures that don’t realize they’re there. Despite their affinity for poison and radioactivity, these gremlins don't wallow in toxic areas—they’re instead drawn to places where non-ill people congregate, such as fitness centers or athletic events. There, vaigruuks spoil food and inflict radiation sickness from a good hiding place. Vaigruuks don’t often work together, as they frequently devolve into bickering about the best way to undertake their sabotage, thus risking getting caught.

Vaigruuks are singularly aberrant, with asymmetrical clusters of beady eyes above two slit-like nostrils and a drooling mouth. Their most prominent feature is fleshy, rabbitlike ears, which are so long they hang down to the ground. Vaigruuks are incredibly vain about their ears and take great care to groom them each day, brushing the clumps of hairy bristles on them. These ears function as radiation receivers and amplifiers, allowing the vaigruuk to sense the presence of nearby radiation and bolster its effects.
