Flash Recall

Prerequisite- The ability to prepare spells, and cast at least one spell.
You’ve developed the ability to instantly recall an unprepared spell in moments of necessity. As an action, you can instantly prepare a spell from your available 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. You then lose preparation of a different spell of your choice of equal or higher spell level. If you are multiclassed, you can only Flash Recall 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.
