First off, to be an effective medic your highest statistics must ultimately be the SpiritStat or the MindStat depending on whether the source of your healing abilities is herbal, magical or scientific.

Secondly, your hometown will be decided by the source of your healing abilities. Wish to be the best surgeon possible? Then choose London as your hometown. Want to combine modern medicine with traditional herbalism? Then choose Lima. Want to specialize in herbal and magical healing? Choose Tara. Only want to have the option of magical healing? Then Agrabah and Kleinstadt would be possibilities depending on whether you wish to be a pure mage or a fighting mage.
