Shaman Question.

[Gordo0331]

I do believe I saw somewhere that a shaman had an option to use his wis mod instead of dex mod for AC purposes. It acted in all ways like the dex mod, just used the wis mod number in its place. I do believe it was not available at level 1, but was looking at making a shaman for PFS play and wanted to begin to set him down the right path. Thanks in advance if anybody can find this.

Probably you're confusing it with a similar ability of some Oracle Revelations that do the same thing using Cha, as most spirit abilities and hexes are based on Revelations from Mysteries of the same name using Wis instead of Cha
