Feature masks are pin-worn items that temporarily change some character features.
You analyze your mask and sense that the creator has provided the following information: This is a feature changing mask. It will temporarily change your features for three hours. If you look at this mask, you will see how it will change your features. Once the time is up, it will fall off. If your hands are both full, it will drop to the ground. Please make sure that you highlight this mask in some fashion so that you can track it. This is what it will look like when the mask falls off: Your facial features slowly grow heavy and seem to harden. Without warning, something solid and smooth slips from your face and tumbles into your free hand.
