Oh, I see. Odd that this skill works differently than all the others. My testing was incomplete as I'd successfully tried Train Familiar and gotten results twice before, but the other actions never returned a result before. Maybe feedback about why the skill failed to increase would be nice?
Maybe I misunderstand how these are supposed to work, but it seems like Go Outside the Fences and Groom Your Familiar should increase the familiar's selected Bond by one step. As far as I can tell they currently don't. Is there some precondition I'm failing to achieve or some probabilistic mechanic that would enable this increase that I am missing?
