Advanced Medical Practices typically require the equivalent of an M.D.
These skills can benefit from a Medical Workers Kit. Toolkits are portable versions of dedicated Work Stations (which offer much better facilities to accomplish their function).
Frame of Reference: All Skills are bound by the character's Setting (physics), and the details that their culture/society's Science (gathered by Technology), direct experience, and/or collective Records are capable of revealing. A character may not be able to apply their full measure on a different world, with different species and tools. With a common frame of reference, multiple specific Lores can stack.
These skills can be attempted on other species. If it is far from the character’s own species type, it may require a Biology and/or Zoology (an appropriate Species Lore may help as well) to apply with efficacy; Truly alien species absolutely will require Biology (Xenobiology preferably).
A character’s base capability in this skill may not exceed that of their same capability in Medical Treatment.
