Spontaneous Spells

If you're a spontaneous spellcaster—such as a mystic—you choose which spell from your spell repertoire that you're using a spell slot for at the moment you decide to cast it. This provides you with more freedom in your spellcasting, but you have fewer spells in your spell repertoire, as determined by your character level and class. When you make your daily preparations, all your spell slots are refreshed, but you don't get to change the spells in your repertoire.
