Always seeking to be in motion, river spirits are temperamental. They tend to become aggressive with little prodding, and equally quick to calm down when their anger has been stilled. River spirits frequently establish relationships with humanoids which live near its riverbed, and when on good terms can grant boons in fish and clean water. When angered, their waters become inhospitable rapids that drown those foolish enough to approach.
When a river spirit takes on a shape, it transforms the water into a shape, often serpentine in nature. While in the water, they are exceptionally hard to detect.
