"Heroics"?

[That's an odd one to hear being taught as a subject in school... but Azul will put a pin in that for now.]

Potionology is... well, what it sounds like, learning how to brew different potions, poisons, and any other liquids using one's magic and special ingredients. Alchemy is similar, though the goal is usually to create or infuse an item with a special component rather than having it in a liquid form.
