In the races of stone there are 2 feats that I have a question about the first is stone form: Stone form gives you a +4 vs poisons +4 to NAC and gives you a slam attack acording to your size large 2d6 med 1d8 small 1d6. The second one is Powerful wild shape: it states that you are considered 1 size larger and that your natural attacks are as if they are one size larger. Now if you are a goliath barbarian with a mountain rage ACF that makes you large for reach and other goodies so the question is if you take improved natural attack ( slam ) what would your damage be

I think it would be that of a colossal char dealing 4D6 damage plus your strangth bonus is this correct ? and if so what happenes if you add in warshaper to the mix ? what would the damage be ?

The last question is can you spend 2 wildshapes at one tie and get both in 1 standard action as it dose say you can spend I would think you could add more into 1 to get other effects

By the way this could be done by level 7
