Contrary to what some may think, mutations are not a combination of the First and Second Mind, instead they are both completely independent when mutating.
Mutations will not be obtainable by players since the game has discontinued, but when it was planned. the First and Second Mind Magic were both going to be able to mutate, while the Third Mind Magic cannot mutate at all. If the player wishes so, they may choose to not mutate their magic to learn additional moves for their source magics.
