Stoneskin not stacking?

[nwmblondy]

She said the Feat and the spell did not stack, not that the spell and the item did not stack.

According to the wiki they do, I'm gonna check IG cos I'm curious.

I cant help but think that there are just exceptions to every damn damage reduction/resistance "rule" and you just have to learn how it works.

*shrug* I don't think theres any exceptions, but you just have to learn how it works. Well you don't have to.
