Boss Swords

Boss Swords are powerful swords that must be recovered from the boss of a Realm before the timer runs out.

Once all twenty-four Boss Swords are restored to the Room of Swords, it is implied that all the voyagers will be returned to their times.

The Boss Swords were formed when Masiosare bombarded a future version of Don with his power, syphoning it away. Either Don or Masiosare (or possibly another version of Masiosare such as Gyrus or the Shadow Boss) can reabsorb the swords.

Appearance
The blade appears reminiscent of medieval longswords or broadswords; the handle is attached to the blade by a ring-shaped hilt through which a person can channel their Breaking Point.

Abilities
While under the possession of a boss or other nonhuman, a Boss Sword will greatly enhance their speed, stamina, and strength, as well as granting them special powers.

When in the possession of a human, Boss Swords will allow them to activate their breaking limit and release their accumulated ruin energy in 'the ultimate expression of their abilities'.

When a person is killed with a Boss Sword before the Shadow hour begins, they restart at the beginning of the voyage's timer, with all their memories, items, and progress intact. However, if they aren't carrying any healing items, they will likely die of the injury. Additionally, this ability only affects the last person to be killed with that sword and can be used with only half a sword.

The Boss Swords are the only item that can be used to damage a shadow creature, though the Shadows are also drawn to the swords.
