The Racnoss appear like massive, red skinned arthropod-like creatures with six pairs of jointed limbs, four to five of which are used for locomotion. Their upper bodies resemble that of a humanoid, making them the vague arachnoid equivalent of a mystical centaur, or Drider. They have a crested skull and three pairs of eyes, and their mouth is human-looking rather than insectile, but contains razor-sharp white teeth. Their abdomen produces a substance similar to spider silk, which can be used to construct vast webs and immobilize prey.
