It's... complicated. [ She trails off, a little frustrated. If Melisandre doesn't even know the term doctor is, she is unlikely to know of golden cores and the like. ] Most of my patients are cultivators like myself. Cultivation permits people to heal faster and withstand greater damage than ordinary people, even without a cultivator doctor's interference. It all comes together. But like I said, it doesn't hinder me much. What does hinder me is that I don't have access to my ingredients here.

[ Far more interesting than her own powers are Melisandre's now. ]

I've never heard of Shadowbinders. [ She pauses. ] Do you know of demonic cultivation? [ Only visually describing what Wei Wuxian does, shadowbinder could easily be the term you'd use... ]
