Exalted - The Venemous Monk
Essence Gem of the Chameleon
The flawless oval gem has no constant color—it can replicate all known colors and Essences. When truly detected and observed, the colors seem chromatic and any color changes are subtle and imperceptible. The perceived Essence of the bearer is identical to the viewer’s Essence type. An exact replica of the viewer’s Caste mark is displayed on the bearer should one become manifested.
Detection: If a supernatural being is attempting to detect the true Essence of the bearer when suspicion arises, the difficulty is a Perception + Occult roll to perceive—typically higher than a regular sense magic roll.
