Rary’s Arcane Conversion

6-level Transmutation (ritual)

Rary’s arcane conversion rewrites the knowledge within your mind. As part of casting the spell, exchange a prepared wizard spell for another spell of equal or lower level. For example, if you wish you had prepared the fly spell, you could as part of casting Rary’s arcane conversion prepare fireball in its place. The replacement spell must be in your spellbook.
