Type: Wild
Source: Races of Stone
You can use wild shape to assume a rocklike form.
Prerequisite: Con 13, wild shape ability.
Benefit: As a standard action, you can spend one of your uses of wild shape to assume a stony and rocklike form. While in this form, you gain a +4 bonus on Fortitude saves against poison. Your natural armor bonus becomes +4 (replacing any natural armor bonus you normally have, though you retain any enhancement bonus to natural armor).
You also gain a slam attack that deals bludgeoning damage equal to a morningstar appropriate to your size (2d6 points for Large characters, 1d8 points for Medium characters, 1d6 points for Small characters).
Normal: Without this feat, a druid can only use wild shape to assume the form of an animal, plant, or elemental.
