A nature spirit has two aspects - one good, one evil. The good aspect leads the nature spirit to be helpful and kind, while the evil aspect makes it savage and cruel. Most times, the two aspects coexist in a harmonic tension, neither one dominant. Spells and sacrifices can sometimes coax one aspect into dominance, however. A nature spirit whose evil aspect is dominant attacks anyone who trespasses on its territory or threatens the place or object to which its lifeforce is tied. A nature spirit attacks with its hands or other appendages. All nature spirits share certain qualities.
Large nature spirits command greater powers commensurate with their higher status.
Spell-Like Abilities: At will - detect evil, detect good, detect magic, invisibility, plane shift (between the Spirit World and the Material Plane only), polymorph self. These abilities are as the spells cast by a sorcerer with as many levels as the nature spirit has Hit Dice (save DC 10 + spirit's Charisma modifier + spell level). In addition to the spell-like abilities common to all nature spirits, Large nature spirits can use shapechange five times per day. A Large nature spirit can also use any wu jen spell associated with the element most closely related to the nature spirit's essence. Thus, a mountain spirit can use any earth spell, while an island spirit can use any water spell. A Large nature spirit can use any given spell once per day.
Local Knowledge (Ex): A nature spirit is intimately familiar with the natural world in the area where it lives. A nature spirit automatically has access to the information learned from the commune with nature spell, effective in an area with a radius of one mile per Hit Die the spirit possesses.
Symbiosis (Su): Each nature spirit is mystically bound to a natural feature - small spirits to a branch, small stone, or stream, medium spirits to a tree, flower, rock, or bamboo grove, and large spirits to a mountain, boulder, ancient tree, or small island. The nature spirit cannot stray more than 300 yards from its feature. If it does, it becomes ill and dies within 4d6 hours. If the feature to which it is bound is destroyed, the nature spirit dies.
Spell Immunity: Large nature spirits are immune to magical attacks that rely on their own elemental nature. Each nature spirit is immune to one energy type appropriate to its environment: fire, cold, sonic, acid, or electricity. For instance, volcano spirits are immune to fire.
Spirit creatures include some fey and elementals (nature spirits), outsiders (celestial spirits), undead (ghosts and ancestors), and even dragons. Spirit creatures are nor necessarily incorporeal, despite their name - in the worlds of Oriental Adventures, some spirits are as much flesh and bone as humans are. The only game effect of the spirit type modifier is that spirit creatures are all affected by spells such as commune with greater spirit, invisibility to spirits, and protection from spirits.
