Suffocation. On a successful hit, the lurker and the target must make an opposed Exert skill check. If the lurker wins the opposed check, the target is engulfed by the lurker. An engulfed target automatically takes 1d4 damage and cannot breathe by normal means. The target can attempt to get free once per round by rolling a new opposed Exert skill check.
COMBAT & TACTICS
Lurkers are passive predators that wait for prey to come into range, and then they silently glide toward the target and engulf it to suffocate it. Smaller targets are usually crushed by the strength of the lurkers, while larger ones simply die due to suffocation. Lurkers prefer lonely preys.
DESCRIPTION
Lurkers are subterranean predators that vaguely resemble a manta ray. Their diameter varies from 1 meter to 6 meters, which probably depends on how old the specimen is. Their color is usually pale white due to lack of pigmentation, but they react to the infrared frequency by emitting pale orange radiation. Instead
of a single mouth, they have small tubular pseudopods placed on their lower body, which they use to feed.
HABITAT
Subterranean and complex ecosystems are a Lurker’s favorite habitat. Mature planets with little or no volcanic and tectonic activity are the right places where you can find this creature. Vast subterranean caves may be inhabited by these predators, which feed on fungus and small creatures. Abandoned mines and artificial subterranean complexes are an excellent hunting ground, especially when some corporations
decide to send an expedition to reclaim the place.
BIOLOGY
A Lurker possesses an advanced biology despite its primitive nature. As siliconbased creatures, they are not very adaptive and they do not mutate or evolve easily, so few strains of this creature exist. Lurkers are still the object of studies among scientific communities, but nothing relevant has been discovered yet.
