Wizards - their magic are achieved through study and hard work. They are wise and usually old, because they spend (ideally) years and years learning magic. They cast spells through the Intelligence attribute.
Think: Gandalf.
Sorcerers - Their magic are innate and derive from their bloodlines. Literally the burgoisie. They did nothing to earn their powers, their parents just so happen to bang a Dragon or a Demon or a Fairy. They use the charisma attribute. Draconic sorcerers can turn into a Dragon when they reach Legendary level. I don't remember what happens to the others, everyone plays Draconic heritage.
Warlock - Literally, they make a deal with the devil. It doesn't have to be a demon or a devil, it can be a fairy or a magical tree or literally any minor deity. They use charisma too, except they work for their patrons. Their magic can go wild, too. It's in my opinion the most varied and fun spellcasting class.
Sorry for any spelling mistakes.
