Arcane Message

You create a short message of twenty-five words or less. The message becomes trapped inside the crystal ball used as a component for this spell. The creature that breaks  the crystal ball hears the message in its mind and recognizes you as the sender if it knows you. The spell enables creatures with Intelligence scores of at least 1 to understand the meaning of your message.

You can disguise the ball in any fashion that doesnt change its general size or shape.
