Animation of the Keybrand. (pre

The Keybrand is a Hardmode, post-Plantera sword. It has a 1/200 (0.5%) / 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 Version 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: Damage * (1 + \frac{5}{3} * (1 - \frac{HP_{Current}}{HP_{Max}}))

(That means, for every 1% health lost of enemy, the damage will increase by  \frac{1}{60}.)

  • If the hit enemy has less than 10% HP: Damage * 2.5

Its best modifier is Legendary.

Notes[edit | edit source]

Trivia[edit | edit source]

  • 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.
  • Despite being a key, it does not unlock anything.
