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 True Excalibur and the Excalibur itself could be a reference to the Soul Calibur, a sword in the Soul Calibur series which represents true good and its counterpart, Soul Edge, represents true evil, which would be the Night's Edge and True Night's Edge in this case.
