Disease in the Twilight World

[Vespers War]

I'm curious why you list Medical: Diagnosis as "effectively up to +5" when a character who's gone to Medical School and spent one term as a Medical Doctor could have Medical: Diagnosis 7.

Going off on a related tangent, Medical is moderately rare in the game. Medical School provides any specialty, as does the follow-on career of Medical Doctor. Registered Nurse provides Medical (Diagnosis) 3. Paramedic has Medical (Trauma Aid) 1. Those are all the civilian careers with Medical. For the Army, Enlisted Medic and Nurse Officer both provide Medical (Trauma Aid) (at 3 and 2 respectively), while Doctor Officer has Medical (Surgery) 3. Army Special Forces and Navy Enlisted Seaman have access only as Subsequent Term Skills. The Air Force has no access to Medical.

In total, one educational track, three civilian careers, and three military careers provide Medical as part of their base skills, and two more military careers have access in subsequent terms. Of those, Medical School/Doctor and Registered Nurse are the best against disease because the others can't take Diagnosis as their cascade specialty and halve their skill for Diagnosis.
