Walter's Wonderful World

Any creature within range of you, with 20 or less hit points, becomes charmed by you for the duration. Any creature with more than 20 hit points must make a wisdom save or become charmed. For the duration you can spend an action to change your visage and the immediate terrain. Any illusory effect must not extend more than 30 feet away form you. The illusion lasts until you make another Illusion or dismiss it as an action. A creature can see through the Illusion by making an investigation check equal to your spell save DC.
