Shocking Bite (Ex)
A skevill gains a +3 bonus on attack rolls against creatures wearing metal armor, and if it hits the target’s touch AC its bite deals electricity damage to the target even if the attack otherwise would have missed.
Static Aura (Ex)
A skevill emits an aura of static around itself to a radius of 15 feet. Every round, this energy coalesces around one creature at random in the area (including other skevills in the area, though these creatures are unharmed due to their immunity to electricity), dealing 1d4 points of electricity damage (DC 14 Reflex half).
This does not require an action. The save DC is Constitution-based.
Static Pulse (Ex)
As standard action, a skevill can target a creature within 30 feet with an arc of electricity. If it confirms a critical hit with its static pulse, the electricity arcs to strike all creatures adjacent to the target, dealing 1d4 points of electricity damage to each (DC 14 Reflex half). The save DC is Constitution-based.
Static Sense (Ex)
A skevill can sense the presence and location of creatures wearing metal armor (or carrying a large amount of metal, at the GM’s discretion) as if it had blindsense 30 ft., or as blindsight if adjacent to the skevill.
Environment any underground
Organization solitary, cluster (2-5), or swarm (6–12) Treasure none
Skevills are subterranean predators that are attracted to large volumes of metal, including veins of unrefined ore. They are the bane of miners and robotic mining machines, scrambling their circuitry and gnawing on all exposed wiring and fragile metallic equipment. While able to metabolic raw ores and metals, they also draw sustenance from gorging themselves on organic material, they extract trace metallic residues along with flesh, blood, and bone. Their curious metabolism produces copious amounts of bioelectricity as a byproduct, and some daring entrepreneurs keep nests of captive skevills to provide light and an erratic source of power, though they do not do well in captivity unless given ample room to move around and prey to hunt.
