The Keybrand attacking a Target Dummy and a Mimic. Note the increasing damage based on the enemy's health.

The Keybrand is a Hardmode, post-Plantera broadsword that has a 1/200 (0.5%) / 399/40,000 (0.9975%) chance of being dropped by Blue Armored Bones, Hell Armored Bones, and Rusty Armored Bones in the Hardmode Dungeon. It deals increased damage against enemies depending on their missing health, up to a maximum of 200% damage against enemies that have less than 10% health remaining. The Keybrand also has a 20% critical strike chance as opposed to the usual 4%.

Its best modifier is Legendary.

Notes

• The following formulas are used when determining the amount of damage that will be dealt:^[1]
  • If the hit enemy has more than 10% HP remaining: [math]\displaystyle{ \mathit{damage} \times \left(1 + \frac{10}{9} \times \left(1 - \frac{\mathit{HP_{current}}}{\mathit{HP_{max}}}\right)\right) }[/math]
    • This means that for every 1% of the enemy's health missing, the damage will be increased by [math]\displaystyle{ \frac{1}{90} }[/math].
  • If the hit enemy has 10% HP or less remaining: [math]\displaystyle{ \mathit{damage} \times 2 }[/math]
• In Don't dig up(Desktop, Console and Mobile versions) and Get fixed boi(Desktop, Console and Mobile versions) worlds, the Keybrand receives the following changes:
  • Switched place with Katana. As a result, it is sold by the Traveling Merchant for 10 GC, instead of dropped by Hardmode Dungeon enemies.
  • Damage decreased from 105 to 15.
  • Sell value decreased from 4 GC to 2 GC.

Trivia

• The Keybrand is based on the Keyblade, a weapon used in the action role-playing game series Kingdom Hearts. It bears an especially strong resemblance to the Keyblade named the Kingdom Key, which Sora wields.
  • The Keybrand's visual effects when striking enemies are likely a reference to similar bright effects that appear when striking enemies with the Keyblade throughout the Kingdom Hearts series.
• Until 1.3.5, items had an unused internal name. Between its introduction and 1.3.0.1, the Keybrand's name was Lockblade,^[2] which may have been its original name during development. This name was never visible in-game.
• Buying the Keybrand from the Traveling Merchant in a Don't dig up or Get fixed boi world also unlocks the "Robbing the Grave" achievement. This is likely an oversight.
• The Keybrand can be considered the counterpart to the Breaker Blade, as the latter deals extra damage to near-undamaged enemies. Fittingly, both are references to swords found in franchises by Square Enix.
