Moodmark Paint

This thick, black paint is stored in a small jar
containing enough for one creature. It is dabbed
on the face in spots or markings that often
resemble the eyes of insects or spiders. Applying
the paint takes 1 minute. For the next 8 hours,
the marks change to reflect your mental state. A
creature that can see you and makes a DC 10
Insight check can discern whether you are happy
sad, angry, disgusted, surprised, or afraid, as well
as the main source of that emotion.
