Spellscholar

Prerequisite(s): The ability to prepare, and cast, at least one spell

Through intense study of your spellbook or holy texts, you have learned a degree of flexibility in your spell preparation. This allows you, in times of extreme duress, to alter your spell preparation for the day. As an action, you can instantly prepare a spell from your available class spell list (or spellbook, if you prepare spells from one) that you did not have prepared. This spell choice must be of a level for which you have spell slots remaining. You then lose preparation of a different spell of your choice of equal or higher spell level.

If you are multiclassed, you can only use Spellscholar to rapidly prepare and swap spells from a class that prepares spells. Once you use this ability, you must finish a short or long rest before you can use it again.
