Ring of Gestures (Patreon)

Ring, common

This gaudy ring has a delicately carved pink gem in the shape of a hand at its center. While wearing this ring, you can cast the minor illusion cantrip at will to enlarge, reduce, and change the color of the hand wearing the ring or any of its fingers. In addition, whenever you make a gesture with the hand wearing this ring, the pink gemstone moves to mimic the gesture and remains that way until you make a new one. 

Some slower folk just won't get the message until you start waving around a giant purple finger or two.
