"A piece of the object to be used at the wall relief.
The "Piece of the Holy Beast, Serpent" is a key item in Resident Evil 4.
It is one of the three insignias needed to open the gate at the end of the Fortress Ruins in Chapter 5-3. It is the final key obtained by Leon.
It is held by Jack Krauser himself, which he claimed was to ensure Leon was on a "very tight leash" regarding finding the other mosaics, and he drops it upon defeat.
