I have a PC Gnome Druid I'm helping a friend build for a Kingmaker game, (though I'm thinking of using a similar build for a PFS character.
He is going wolf shaman with a wolf animal companion. Since he is a gnome (small) and wolves are considered medium size, if he has its tricks and general purpose set for mounted combat stuff, and has the mounted combat feat, could a gnome ride a wolf? If its legal I'm totally gonna make a PFS character for it.
