Type: Wild
Source: Races of Stone
You retain your powerful build while in wild shape form.
Prerequisite: Wild shape, powerful build racial trait.
Benefit: As a standard action, you can spend one of your uses of wild shape to assume a powerfully built version of a creature you can normally wild shape into. While in this form, you retain the benefits of your powerful build racial ability and are considered one size category larger than normal for many effects (see the goliath racial traits on page 56, Races of Stone for details on powerful build).
While using Powerful Wild Shape, you deal damage with your natural attacks as if you were one size category larger (see the Improved Natural Attack feat).
