Healer

In adventuring parties, the healer primarily focuses on keeping the other members of the party alive. These adventurers are often, but not always, clerics. 
Medical knowledge can be learned without access to magic, it simply takes more care and time, but in broader society such individuals can be invaluable to a settlement, particularly the herbalists who learn the medicinal properties of certain plants when prepared properly.
Some healers in more advanced nation states have taken on the title of "doctor" and claim their more advanced techniques can be even more beneficial to long term wounds than basic magical healing. The actual results are, at best, inconclusive on this point.
