Unnamed Eye Armor Piece

The Unnamed Eye Armor Piece is a lost item presumably created by Cleare. It was later used by Vandel.

Volume 3
Cleare gave the armor piece to Luxion and Leon before it self destructed. Luxion absolutely hated being given the piece and convinced Leon to drop it off of Partner before destroying it with his main gun after they left Elven Island, much to Hertrude's anger and confusion.

The armor piece is later taken from the Kingdom's treasury by The Principality and equipped to Vandel's armor. With the armor piece, Vandel is able to overwhelm Leon and Arroganz. However, Leon gains the upper hand when Arroganz merges with Schwert and comes out on top, destroying the armor.

Upgrading
The armor piece is able to upgrade any armor it's attached to, covering it with eyes and giving it flesh like enhancements. It increases the armor's strength, speed and durability, however, it can cause a large amount of strain on the armor's user, even pushing them to the point where they begin lose rational thought.
