"If the patient is not dead, then recovery is a question of magnitude--a potent mage may cast a great spell, to heal grievous wounds all at once, or an apprentice might cast simple cantrip after cantrip, but with sufficient time and magicka, that apprentice could restore the same patient just as fully as the greater mage." He pauses for another mouthful of soup before taking a slight tangent. "Of course, there are other maladies than injury, and many of these require particular spells to set right, which demand a certain threshold of aptitude. So while potent mage and apprentice might both in their own time heal a patient badly wounded, the apprentice would be harder-set to tend a victim of poison or fever."
