A plain looking golden ring that only reveals it's true form in the presence of divine or infernal entities. (True form is a ring with a half angelic half demonic face in the middle of it and clasps that dig into the flesh shaped like claws)
Binds upon being placed on finger or toe.
+20 to Charisma based skills and saving throws, however, everytime you use Charisma based skills or saving throws you take d4 constitution damage (heals after a long rest).
Also everytime you speak, it comes out as the opposite of what you meant.
