Nature Spirit

The shaman's spirit animal looks feral, and appears to be in peak physical form. The animal can move through any sort of undergrowth or natural difficult terrain at its normal speed without taking damage or suffering any other impairment. If the animal has a fly speed, it can ignore the penalty on Fly skill checks for winds up to windstorm strength.

A shaman who chooses the nature spirit as her spirit or wandering spirit gains the following ability. Storm Burst (Su): As a standard action, the shaman causes a small storm of swirling wind and rain to form around one creature within 30 feet. This storm causes the target to treat all foes as if they had concealment, suffering a 20% miss chance for 1 round plus 1 round for every 4 shaman levels she possesses. The shaman can use this ability a number of times per day equal to 3 + her Charisma modifier. At 11th level, any weapon she wields is treated as a thundering weapon.

A shaman who chooses the nature spirit as her spirit or wandering spirit gains the following ability upon having access to the greater version of that spirit. Spirit of Nature (Su): Whenever the shaman is reduced to below 0 hit points, she automatically stabilizes and gains fast healing 1 for 1d4 rounds. At 15th level, this increases to fast healing 3.

A shaman who chooses the nature spirit as her spirit or wandering spirit gains the following ability upon having access to the true version of that spirit. Companion Animal (Su): The shaman's spirit animal takes the form of an animal companion of her choice, using her shaman level as her effective druid level. The animal retains all the special abilities and the Intelligence score of the spirit animal, but also has the statistics and abilities of an animal companion. If the animal is dismissed, is lost, or dies, it can be replaced in the same way as a normal spirit animal.

Upon reaching 20th level, the shaman becomes a spirit of nature. Once per day, she can surround herself with an organic cocoon of silk as a full-round action. While enclosed in the cocoon, she's considered helpless. Eight hours later, she emerges, having changed her type to plant, animal, or humanoid, and having gained superficial physical characteristics of the chosen type as appropriate. She must choose a type that is different from her current type. This effect change doesn't alter her Hit Dice, hit points, saving throws, skill ranks, class skills, or proficiencies. The effect is permanent, until the shaman chooses to transform again. Each time the transformation is made, the shaman is cleansed of all poisons or diseases, restored to full hit points, and healed of all ability damage.
