Legendary Regalia

Legendary Regalia are the most powerful regalia in existence and were created by Atlas, the greatest smith in history. All of the Legendary Regalia have unique abilities, with some of these coming at a major cost to the wielder. There are five Legendary Regalia.

Excalibur
Main Article: Excalibur

The single most powerful Legendary Regalia, Excalibur's Regalia Stone is located in the Tomb of Kai. Excalibur is a long-sword. In order to wield Excalibur, the user must sacrifice their life to the sword. The outcome of this is that the user, win or lose, will die at the conclusion of the battle. The user's soul is then absorbed into Excalibur, thereby increasing its future power. The closer the user comes to death while wielding Excalibur, the brighter it shines and the more powerful both the user and Excalibur become. In addition, returning Excalibur to its scabbard will heal the wielder for as long as Excalibur is in the scabbard, unless the wielder drops into critical levels of damage. In the instant that Excalibur is removed from its scabbard, it blinds the opponent briefly with its bright light.

Muramasa
Main Article: Muramasa

Muramasa is an extremely powerful Legendary Regalia, second only to Excalibur in power. Muramasa is a katana. Though there is not an immediate cost to wield Muramasa, like Excalibur, Muramasa has its own set of dangers. Unlike the other four Legendary Regalias, Muramasa is actually sentient. Muramasa is a bloodthirsty killer and therefore needs to kill. While each kill with Muramasa enhances its power, it also staves off its own craving for murder. The longer a fight drags on while wielding Muramasa, the more powerful Muramasa's pull on the user. Eventually, Muramasa can completely take control of the user's body.
