[PFS] Chosen One Pladin of Erastil

[Nohwear]

I am strongly considering making a Chosen One Paladin. One idea that seems interesting is to make my familiar a Petrifern. Does it seem like a bad idea take a familiar that is not useful in combat? Does anyone know of any legal advanced familiars that would continue with the plant theme?

You could say the orrery form of a Harbinger is wooden.
Earth Elemental also works; the petrifern learned how to move while petrified.

A Paladin is powerful enough that it's OK if you spend resources on a familiar that's not useful in combat. If you semi-optimize the rest, and use semi-decent tactics, you should do fine in PFS play.
