DESCRIPTION

You swap one of your spells known for a spell you have access to in the form of a spellbook or scroll. (The spellbook or scroll serves as a focus for this spell, and is not altered in any way.) The spell must be of 3rd level or lower and be from the sorcerer/wizard spell list. You must choose to temporarily lose access to a spell known of the same spell level as the spell to be gained through mnemonic alteration. For the duration of this spell, you can cast the new spell as if it is one of your spells known. When the mnemonic alteration ends, you lose access to the spell it granted you, but regain the ability to cast the spell known you temporarily sacrificed.
