Betrayal 9 (Patreon)

The petrification amulet isn't a unique item but it IS rare, which makes it remarkable that we've seen one being used on Earth.  It's know by many names. Medusa's Eye, Medusa's Gaze and Baleful Gaze are but a few.  It requires a Medusa's soul  to make one.  Needless to say, anyone using one within eyeshot of a Medusa will most assuredly get attacked.
