Crystal serpents resemble fat 3 ft. long snakes of more normal variety, except that they are composed of minerals and crystals, speckled with tiny geodes, with gem-like eyes. It is likely that they once were denizens of the Elemental Plane of Earth, but now live and breed on the Material Plane, hunting small animals by erupting from sand and stone, biting and shocking them to death. They have also been known to coil around stalagmites and enjoy dripping minerals; they otherwise dislike and avoid water. Crystal serpent eggs look like tiny, beautiful geodes, and are laid underground in clutches of 4-10, though the young are quite prone to cannibalism of their siblings. Collecting the pretty ‘gems’ seems to be profitable for casual spelunkers until they hatch; the young can deal a nasty shock for 1 hp of damage if handled. These creatures are fairly intelligent and will converse with beings that are bigger than they are and can speak with them, and do not pose a threat. They enjoy treats of acidic food and may respond with local information about their environment or even nearby mineral deposits. Dwarves sometimes employ them in this regard, calling them ‘sniffer snakes’, though they are prone to escaping to pursue their own whims.

Crystal serpents are common hazards in the southwestern deserts of Siwath, Simoon and Ghadab. Though the Creeper’s Rift lies within this region the crystal serpents seem unable to breach the godswall that surrounds it. Arcane spellcasters who are devoted followers of Drothos, Enor Ashlord, or Najim may select a crystal serpent as a familiar at 5th level with the Improved Familiar feat.
