Wild Shape (Su): At 5th level, a druid gains the ability to turn herself into any Small or Medium animal and back again once per day. Her options for new forms include all creatures with the animal type (see the Monster Manual). This ability functions like the polymorph spell, except as noted here. The effect lasts for 1 hour per druid level, or until she changes back. Changing form (to animal or back) is a standard action and doesn’t provoke an attack of opportunity.
The form chosen must be that of an animal the druid is familiar with. For example, a druid who has never been outside a temperate forest could not become a polar bear.
A druid loses her ability to speak while in animal form because she is limited to the sounds that a normal, untrained animal can make, but she can communicate normally with other animals of the same general grouping as her new form. (The normal sound a wild parrot makes is a squawk, so changing to this form does not permit speech.)
A druid can use this ability more times per day at 6th, 7th, 10th, 14th, and 18th level. In addition, she gains the ability to take the shape of a Large animal at 8th level, a Tiny animal at 11th level, and a Huge animal at 15th level. The new form’s Hit Dice can’t exceed the character’s druid level. For instance, a druid can’t take the form of a dire bear (a Large creature that always has at least 12 HD) until 12th level, even though she can begin taking Large forms at 8th level.
- The assumed form can’t have more Hit Dice than your caster level.
- Upon changing, you regain hit points as if you had rested for a night (though this healing does not restore temporary ability damage and provide other benefits of resting; and changing back does not heal the subject further). If slain or knocked unconcious, you revert to your original form.
- You gain the Strength, Dexterity, and Constitution scores of the new form but retain your own Intelligence, Wisdom, and Charisma scores. You also gain all extraordinary special attacks possessed by the form (such as constrict, improved grab, and poison) but do not gain the extraordinary special qualities possessed by the new form (such as blindsense, fast healing, regeneration, and scent) or any supernatural or spell-like abilities.
- Any gear worn or carried by the druid melds into the new form and becomes nonfunctional. When the druid reverts to her true form, any objects previously melded into the new form reappear in the same location on her body that they previously occupied and are once again functional. Any new items worn in the assumed form fall off and land at the druid's feet.
A druid can use this ability more times per day at 6th, 7th, 10th, 14th, and 18th level, as noted on Table: The Druid. In addition, she gains the ability to take the shape of a Large animal at 8th level, a Tiny animal at 11th level, and a Huge animal at 15th level.
At 12th level, a druid becomes able to use wild shape to change into a plant creature with the same size restrictions as for animal forms. (A druid can’t use this ability to take the form of a plant that isn’t a creature.)
At 16th level, a druid becomes able to use wild shape to change into a Small, Medium, or Large elemental (air, earth, fire, or water) once per day. These elemental forms are in addition to her normal wild shape usage. In addition to the normal effects of wild shape, the druid gains all the elemental’s extraordinary, supernatural, and spell-like abilities. She also gains the elemental’s feats for as long as she maintains the wild shape, but she retains her own creature type.
At 18th level, a druid becomes able to assume elemental form twice per day, and at 20th level she can do so three times per day. At 20th level, a druid may use this wild shape ability to change into a Huge elemental.
