Esoteric Medicine
Default: Perception-6.
This is the skill of treating illness and injury with techniques grounded in esoteric theory rather than analytical science. It is usually associated with a magical or spiritual tradition. The particulars vary by tradition, but might include acupuncture, massage, alchemical or herbal preparations, or such exercises as breath control and meditation.
The effectiveness of Esoteric Medicine relative to Physician is up to the GM. It might be more effective (especially if it can channel real supernatural power), equivalent but different, or less effective. It should always be at least as good as First Aid – the attentions of a trained healer of any kind are preferable to bleeding to death! In TL5+ settings, Esoteric Medicine is often perceived as "quack" medicine, regardless of actual effectiveness.
This skill might represent Ayurvedic medicine, chi treatment, Hermetic medicine, yin/yang healing, or any other historical or fictional healing discipline. In settings where multiple forms of treatment exist, healers must specialize in one specific tradition.
Martial Arts
In a realistic setting, the chi-based attacks of martial-arts myth are so much mumbo-jumbo. They're normal strikes and grapples, and the injury they inflict is treatable with mundane medical skills. A Psychology roll might be needed to convince the patient that he's suffering from a bruised kidney and not the dreaded dim mak, of course!
In a cinematic setting where such abilities as chi powers (see Chi Projection) and the Pressure Points and Pressure Secrets skills exist, though, only Esoteric Medicine can recognize these things and treat their effects. Mundane medicine can heal lost HP, but it can't halt further injury from an ongoing effect or alleviate its symptoms. At the GM's option, Esoteric Medicine might rival mundane medicine when it comes to treating ordinary illness and injury, too. If so, it can do everything that Physician can do, and any skill with a Physician default (e.g., Diagnosis, First Aid, Pharmacy, Physiology, Poisons, and Surgery) defaults to Esoteric Medicine at the same penalty.
