Eilmer of Malmesbury's Wings

Origin
Eilmer of Malmesbury was an 11th century Benedictine monk best known for his attempt at flight.

As one who had read and believed in the story of Daedalus, he affixed wings to his hands and feet and jumped from the top of the Abbey tower at the time. As he had no tail to maintain equilibrium, he crashed, but lived.

Effects
When worn, the wings allow the user to glide from any starting position or altitude. However, without a tail, the user has no real control of direction or equilibrium, and so is likely to crash, albeit they will always survive no matter the force or height.

Trivia

 * As the artifact's downside is not from an effect, but rather due to is design, it is possible that if a large tail were constructed, this artifact could be used on field missions when required. The design and creation of the tail is currently in waiting.
