Keybrand

The Keybrand is a near-endgame sword found within the Dungeon during Hardmode and after Plantera has been defeated. It is rarely dropped by Blue Armored Bones, Hell Armored Bones, and Rusty Armored Bones. It is better than the sword Excalibur in use time, though only by a small amount. It can support the Legendary modifier.

Trivia

 * This weapon is based on the Keyblade, a weapon obtained by Sora in the Kingdom Hearts series. It resembles the Kingdom Key Keyblade that is obtained at the start of the first game.
