"The arrowhead looks like it can be removed."
The Golden Arrow (金色の矢 Kin'iro no ya ) is a key item in Resident Evil.
The tip of the arrow can be removed to use in the backyard graveyard of the mansion to reveal a crypt with four death mask statues and the coffin of the Crimson Head Prototype 1.
When examined it will be revealed that the tip is made of peridot, which is sometimes referred to as a "poor man's emerald."
The Golden Arrow can be found in the mirror corridor on level 2F of the Spencer Mansion.
