Kleidos

The Kleidos is a powerful ancient relic in Castlevania: Lords of Shadow 2. It allows Dracula to enter challenges in Chupacabras' Shop. Only the Chupacabras can read the ancient spell to open the gate.

It looks like a small mask in which 16 nails can be insered. Every 4 nails will open a new series of challenges.
