Excalibur

Excalibur is a legendary sword, apart of the 7 Swords of Heaven. It is a powerful sword that was once in possession of the Celestial Dragons, until it was stolen by Airi of the Gear Pirates during the World at War Arc.

Appearance
Excalibur has a length of around 90cm, and is 12cm wide. It had a blue handle, and a silver blade that can sometimes turn golden.

Abilities
Excalibur is a Holy Sword which means the wielder must be worthy. If not, it becomes too heavy to use. If it does find a worthy user, the powers it holds are immense.

The blade can repel dark forces that might plague those around it. It could also enhance the physical attributes of its user for a short period of time.

Strengths and Weaknesses
The blade itself is nearly unbreakable. It can cut through almost anything, and level the entire battlefield with its power. However it takes massive toll on the users body when it is used. The user cannot use Excalibur in a strenuous battle where the outcome could go either way, the strain of using the blade will deplete the wielders energy eventually drawing into their life force.

In order to avoid this, the wielder has to maintain a healthy balance of mental and physical strength.
