The crysmal is a scorpion-like creature from the Elemental Plane of Earth.
Gemlike Appearance. Each crysmal has a unique appearance. While each are created from gems or crystals, each has different patterns, edges, and consistency based on the stones used to create it.
Driven to Propagate. The crysmal seeks to create more of its kind by converting gems and crystals into new crysmals. It may seek conflict with adventurers, knowing they often carry valuable stones. It takes the crysmal an hour with 8 or more gems worth at least 25 gp each to create a new crysmal. If forced to use other minerals, the creation of a new crysmal takes significantly more time.
Elemental Nature. The crysmal doesn’t require air, food, drink, or sleep.
