When you cast this spell, you create a magical disguise known as a persona. To create a persona, give it a name, describe its physical appearance and characteristics (it can be of any race the same size as you are or one size smaller or larger), and detail its outfit. You also choose one skill and one language.   You adopt this persona immediately when you cast this spell. While you have adopted a persona, you physically transform into the creature you described. In addition to retaining your normal proficiencies and languages, you have proficiency with the chosen skill, and can read, write, and speak the chosen language. You can use an action to end this transformation, returning to your typical appearance and losing the bonus skill proficiency and additional language.   Each time you end the transformation, you can choose to place the used persona in a mystic repertoire called your archive. You can have a number of personas in your archive up to your spellcasting ability modifier. If you wish to add a persona to your archive and already have the maximum number, choose and replace one persona you already have with the new one. When you cast this spell, you can choose to forgo providing the material components to adopt a persona in your archive instead of creating a new one.
