First Aid:
So the rulebook states you can use Craftsmen: Veterinary as a substitute for First Aid on monsters with an animal metabolism. This sets a precedent for other Craftsmen skills to be used in similar ways to different creature types. Craftsmen: Ichthyologist for insectoid creatures such as the Ankheg, Craftsmen: Botanist for plant-like creatures such as the Spracta.
And Healing Arts:
Things with no metabolism aren't Healing Arts-able, which I perfectly understand and support. It does say (Under healing arts) that creatures of different types with Alien metabolisms(Naga, Giant Spiders used as examples) could healing arts each other if they had the skill. This says to me that things with Alien Metabolism are certainly HA'able with the right skills.
So, these skills exist, a Naga can use healing Arts on another Naga to assess their health, etc. He can do this because the skills he needed to learn to do so, while different than the ones a human or elf would learn as the Healing Arts skill, exist and are teachable. So, what is to stop PCs from researching the physiology of a Naga? They know the Naga can use healing arts, or could at least infer that the Naga was using HA on that other Naga over there. What if a PC charmed that Naga and asked them to teach them Healing Arts? Would you learn Naga HA or some kind of craftsmen?
