Console and Old-gen console versions 3DS version Animation of the Keybrand.

The Keybrand is a Hardmode, post-Plantera sword. It has a 0.5*1/200 (0.5%) / 0.75*1/133 (0.75%) chance of being dropped by Blue Armored Bones, Hell Armored Bones, and Rusty Armored Bones in the post-Plantera Dungeon.

Desktop and Mobile versions The Keybrand gains more damage against a previously-injured enemy, up to 150% extra damage (250% damage in total). The following formula is used:[1]

  • If the hit enemy has more than 10% HP: \mathit{Damage} \times \left(1 + \frac{5}{3} \times \left(1 - \frac{\mathit{HP_{Current}}}{\mathit{HP_{Max}}}\right)\right) (That means, for every 1% health lost by an enemy, the damage will increase by \frac{1}{60}.)
  • If the hit enemy has less than 10% HP: \mathit{Damage} \times 2.5

Desktop and Mobile versions Additionally, striking any enemy with the Keybrand will cause a sparkling visual effect.

Its best modifier is Legendary.



  • 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.
    • Desktop and Mobile versions 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.
