Your self-belief has power. As long as you believe yourself to be something, you will be it. This lets you instantly teleport to any location by believing you are there, heal from any wound by believing you are unscathed, or change your form by believing that it is your appearance. The only limitations are that it cannot augment your powers or mind, create items, or affect others. You cannot believe you have the powers of Eidolon and suddenly have the powers of Eidolon or believe that you are the richest person in the world to get money. This power also maintains your consciousness if you assume a form that doesn't have a mind, such as a pool of water. Your consciousness is maintained even in death, allowing you to resurrect yourself.
