Legend
they get spells, from the PHB and whatever other source we use. They do not get to make up a brand new spell and there can be spells outside those sources that enemies use…Based on the PHB? It does say, right there, in black and white, when I gain a level, I gain spells known. Wizards automatically get two new spells in their spell book. There's no "quid pro quo" there's no const. There's nothing. I get whatever level appropriate spell my little heart wants.
My point was not that they get no spells at all, it was that there are spells they cannot get because they have no idea they exist, and yet someone else somewhere in the world knows those spells. The characters do not have universal knowledge about all the spells that exist
