As she advances in level, a combat medic gains abilities
that enhance her healing skills. She also continues to gain
spellcasting power.
Spellcasting: As you attain more levels, you continue
your training in your chosen spellcasting field. You get
new spells per day, spells known, and an increase in caster
level as if you had also gained a level in any one spellcasting
class that includes cure light wounds on its spell list,
provided you belonged to that class previously. You do not,
however, gain any other class feature
a character of that class would have
gained. This essentially means that
you add the level of combat medic
to the level of whatever eligible
spellcasting class you have, and then
determine spells per day and caster
levels accordingly.
