What to do with Bones?

So, I can't help but notice that, despite a wide variety of types of bones and a way to make chitin into bones for recipes, it doesn't actually do anything with the stats it has. You can find Fabled bones that grant a wide array of stats, but there is nothing to pass these stats onto. I can only find a couple augments and health potions to use bones on and none of those take the attribute stats from bones. So, I'm just wondering what point these resources have in the game?
