I have no idea where to submit this one so hopefully this is the right place xD

My idea would be that you could maybe be able to craft a bone marrow, as the title say. I was thinking that maybe the rib bones could work as the material needed and that you would need 10-15 of them for one bone marrow.
This would not change anything about the marrow itself, you could still only use it once per day and it would give you 20% energy.

I'd love to hear your thoughts about this :3
