True Excalibur

The True Excalibur is a stronger version of the Excalibur, doing additional damage and gaining the ability to shoot a glowing pink image of itself in the direction of your cursor. This ability has a short cooldown, so if the sword is being swung rapidly not every swing will fire a glowing sword. The fired glowing sword can pass through 1 block wide gaps.

Unlike the standard Excalibur you cannot hold the mouse button down to continuously attack.

Trivia

 * The Excalibur and Night's Edge may be a reference to the game series Soulcalibur, in which there is a good sword called the Soul Calibur, and an evil sword called the Soul Edge. This may however be a coincidence.
