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 sword which causes a sparkling visual effect upon damaging an enemy. 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%. The Keybrand has a 1/200 (0.5%) / 399/40000 (1%) chance of being dropped by Blue Armored Bones, Hell Armored Bones, and Rusty Armored Bones in the post-Plantera Dungeon.

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.

Tips

  • The Keybrand's ability to do more damage against previously injured targets makes it an exceptionally good choice against slow-moving, high-health targets such as Nailhead or the Ogre.

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.
  • Despite being a key, it does not unlock anything.
  • The Keybrand is the best of the weapons that create no projectiles.
  • 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.
