Training in a magic academy has exposed you to students and professors outside your spellcasting tradition. Select one spell from a spell list other than your own. It must be of a level no greater than 1 lower than the highest level spell you can cast. Add this to your list of spells known. Each time you gain the ability to cast a higher level of spells, you can swap out the spell gained with this alternate class feature for a new spell of a maximum level no greater than 1 lower than the highest level spell you can cast.
