Obsidian Scarab

The Obsidian Scarab is a talisman the Three sisters threw to Rosella after she snatched their shared eye. It protected Rosella from the wandering Zombies on the Whatley Manor grounds, and from the Mummy guarding Pandora's Box.

Behind the scenes
The Scarab in Egyptian mythology is a symbol of resurrection and life from death, as ancient belief said it sprung spontaneously from piles of dung. If you go to the graveyard at night without the talisman, the zombies' touch will kill Rosella and turn her into a wandering undead. If you use a cheat code to enter the crypt without appeasing the ghosts first, you will get the narration asking you flat-out how you managed to do it.
