Phoenix Eye

"Its eye burns with a fire that consumes the life force of anybody it comes in contact with."

- Gaius to Merlin about the Phoenix

The Phoenix Eye is an amber crystal that can be enchanted to consume the life force of anyone it comes in contact with.

History
Morgana gave Arthur a Phoenix Eye bracelet before he embarked on a quest to find the Fisher King's trident. The bracelet was given to her by Morgause, who instructed her to bind the bracelet to a poppet representing Arthur. This would allow Morgana to drain his life force while he was away.

The Eye weakened Arthur throughout his journey and he eventually collapsed after reaching the Fisher King's tower. Fortunately, Merlin and Gwaine caught up to him and Merlin removed the bracelet before Arthur's life force was drained completely. Merlin later gave the bracelet to the Fisher King in exchange for the Avalon Vial, granting him the death he desired (The Eye of the Phoenix).

Trivia

 * The Phoenix Eye was named after the Phoenix, a creature of magic whose eye burned with a fire that could consume a person's life force (The Eye of the Phoenix).
 * The effects of the phoenix eye are somewhat similar to the effects of poppets, which can be enchanted to absorb magic in a similar manner (The Eye of the Phoenix, The Sword in the Stone).
 * The Phoenix Eye may be made from Baltic amber like other medieval items.
