Type: Wild
Source: Masters of the Wild
You use wild shape to become animals of your own size even if your wild shape ability would normally exclude that size category
Prerequisite: Ability to use wild shape, natural form neither Small or Medium-size
Benefit: You use your wild shape ability to take the form of an animal whose normal size category matches your own. For example, a cloud giant druid (size Huge) with this feat could use wild shape to become a Huge shark or a giant squid.
Normal: The size of the animal form you can assume through wild shape is limited by the parameters of ability, regardless of your original size.
