The Amulet (お守り) is an item in Eastern Mind: The Lost Souls of Tong-Nou. It is given to Rin by a white snake in the beginning of the game. It can also be obtained from Mai-chiu in the Phantom Marketplace Hou-ang by trading him an Eyeball-Stone and either a Wind Chime or Chopsticks.
The primary use of the Amulet is to protect Rin once from death. It disappears afterwards.
