This is not what I expected. No wonder the mercenaries I have seen so far are all warriors. Even though there are medics among them, they are usually carrying big bags containing herbs and concoctions inside a bottle all stuffed inside their bags which is opposite to what I envisioned of Healers who are all carrying a staff and wears a white robe.
If all people are reliant on using Philosopher's stones to use magic, then the people are all going to have a dire need of supply to the Philosopher's stones.
