Clinging to an icy wall is a bizarre creature. The disturbing crystal spider lives in areas that most other monsters cannot reach. It can even scale sheer ice cliffs with its strong legs. Swarms of young crystal spiders have also been seen with these monstrosities.

Snow Spider. Crystal spiders can hide in the snowy terrain and surprise their victims. It’s quite the sight to see this massive spider make its presence known.

Patient Predator. Ambushing other creatures is what the crystal spider does best. They are very patient and will wait hours and hours for prey to wander by. Then the crystal spider spits a cold paralyzing liquid. Once the target is immobilized, the monster will drag the victim off to its lair.

Icy Inhabitants. The spider’s crystal caves are usually hidden far away from other creatures. These lairs are littered with crystals, gemstones, bones, and furs. Finding these lairs is an adventure in itself.
