A large worm composed entirely of crystalline segments that are harder than most metals. It has gaping jaws, lined with saw-toothed ridges that can tear through most non-magical armor. It does not require air to live, so can be found in areas of poisonous games. Instinct: To drive off intruders

• These crystaline creatures dwell in mineral-rich pools often found in deep caverns. While essentailly a docile species, these solitary creatures known to viciously and fearlessly attack anything that disturbs thier environment.
• SPAWN SHARD: Each time the creature takes damage from a physical attack, a shard of its crystal body will break off. This shard will immediate begin to search for an organic host to burrow into, so that it may feed and develop into a larvae, then eventually in an adult. Once a host is contacted, the shard will burrow through to the center mass of the victim within (three counts of a clock), causing 1d6+3 damage for each count.
