What was a slime creature that could detach from its lower body to run away from danger then simply regrow its lower body over time has now been infected with oredeclinatio turning its body into a crystal like substance. It can no longer separate from its lower body at will, it does however have a good amount of durability it can use to help make it through the land. Fighting this creature would kind of like fighting a horse, that has extra legs on a upper chest.
