Dome of Tranquility

As soon as you cast this spell everything inside of a 50ft radius from the destination you cast it becomes peaceful. No violent actions can be made in this dome, no violent movements, no hateful words. The inside and outside of the dome can look however the caster wishes it to look. In the dome anyone and everyone is relaxed and loving, and yes I mean everyone. From the raging barbarian to the pure evil BBEG.
