I am learning Piety right now, but, I don't really "get" what the skill is from the description. Something about reaching tall shelves.... could that mean being able to get things from home without having to walk/teleport there? That would be nifty.
But I'm a tad worried about the other part, i.e., priming a shrine for "vengeance" -- any clue what that means? I thought this game was so positive . . .
