You can change one 6th level or lower memorized spell for any spell of the same level or lower from your spellbook. Your spellbook must be within a mile of you. You forget your memorized spell, and treat the spell from your spellbook as if you had memorized it. When the spell ends, you forget both spells. Only one spell can be called for each casting of Mordenkainen's penultimate cogitation.
