Root golems are rare entities found only in topic climates, especially swamps. There are two ways a root golem can come into being. One is if a nature spirit deems it fit to cloak itself in roots and vines and muck. But an easier, less painful choice is to find a host, and possess vines, roots and muck to gather around their body. In return for form and shelter, the spirit will grant its host a variety of abilities, such as regeneration and vegetation manipulation.
