The nightosphere amulet is being dropped out of nowhere that came from the nightosphere portal and closes a portal

It’s up to you that you can wear it to control the nightosphere powers without amulet taking over your body, but if you wear the necklace then the black lquid will comes out of the purple gem and rotate around your body since it will cover normal outfit to form black suit

The nightosphere amulet does not talk or doing anything unless someone should wear this amulet
