So I think most of us know what Spirit Bone Fusion is other wise you can find it on Spirit Bones. We know Tang San has it, or will have it. It depends on where you're at in the LN. But Bibi Dong is suspected to have it, I really don't know if she does, I'd love it if you could tell me. But the main question I had was, do you think if the spirit bone is older it means there's a higher chance of spirit bone fusion?
I was thinking for example if you have 6 10,000 year old spirit bones set (from the same spirit beast) has a lower chance to have spirit bone fusion than 6 100,000 year old spirit bones set (from the same spirit beast).
