Keybrand

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