I have an arcanist character with the School Savant archetype, which allows me to prepare an extra spell per level of the chosen school (Air in my case) but requires two preparation slots for a spell of the opposing school (Earth for me).
I also have the Quick Study Arcanist Exploit which lets me swap a prepared spell for a different spell in my spellbook.
The interaction of quick study with these school spells are not exactly clear. For example:
- If I choose to replace a specific Air school spell that I prepared, am I restricted to choose another Air school spell as a replacement?
- Can I replace a normal spell with an Earth school spell, thus bypassing the need for 2 "preparation slots" (or do I need to replace 2 spells perhaps, or something else)
So how does replacing prepared spells with Quick Study work when both specific school spells from School Savant and other spells are involved?
