A masterpiece can take many forms and shapes, as many as there is ways to express art. If you are within 5 feet of the masterpiece, you can use an action to speak its command word and activate it. It remains activated until you use an action to speak the command word again. Any creature other than you using an action to interact adequately with the masterpiece must succeed on a DC 15 Charisma saving throw. On a failed save, the creature gains the ideal of the masterpiece’s author, which overrides any opposing ideal. At the end of each long rest, the influenced creature can repeat the saving throw. On a successful saving throw, the creature loses the new ideal. If a creature successfully saves against the effect, it is immune to the influence of the masterpiece. Casting the dispel evil and good spell on the creature also removes the new ideal.
