After playing for a bit it is clear that some of the spells I picked are not that great. I'd like to learn some other spells to switch out my bad or redundant spells, but I haven't found out how to learn more spells outside of leveling up.
How do I learn more spells as a wizard?

According to the pillars of eternity wiki, wizards can learn new spells by leveling up or by reading looted enemy grimoires and paying a research cost.

I have not yet encountered any enemy grimoires in game to test this.
