Pathfinder 2e Action / Feat: Arcane School

Description Many arcane spellcasters delve deeply into a single school of magic in an attempt to master its secrets. If you want to be a specialist wizard, choose a school in which to specialize.
Applications You gain additional spells and spell slots for spells of your school. If you don’t choose a school, you’re a universalist, a wizard who believes that the path to true knowledge of magic requires a multidisciplinary understanding of all eight schools working together. Though a universalist lacks the focus of a specialist wizard, they have greater flexibility.
