The Vampire Knives in action against Target Dummies and a Unicorn.

The Vampire Knives are a Hardmode, post-Plantera melee weapon that autofires a spread of red knife projectiles. When a knife hits an enemy, a red beam will extend to the player, providing a lifesteal effect which heals the player by 7.5% of the damage dealt (rounded down). The Vampire Knives fire between 4 and 8 high-velocity knife projectiles at a maximum spread of approximately 45°. The projectiles are not affected by gravity, but at 28 tiles will begin to spin and fade, dissipating entirely after another 26 tiles (54 tiles total range). Melee speed bonuses will make the projectiles travel faster and farther. The projectiles may disappear visually a few tiles before they actually become ineffective. Each knife projectile will deal the weapon's full damage until it begins spinning and fading, at which point its damage drops gradually until it dissipates. The Vampire Knives are always found in the Dungeon's Crimson Chest, which can only be unlocked with a Crimson Key after Plantera has been defeated.

Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount.


For the limitations of the lifesteal effect, see Lifesteal.
  • At least 4 knife projectiles will always be thrown. There are 4 independent chances (1/2, 1/4, 1/8, and 1/16) to increase this number by 1,[1] resulting in a maximum possible number of projectiles of 8. The following table visualizes the number of projectiles and the respective chances:
# Chance
4 315/1024 (30.76%)
5 486/1024 (47.46%)
6 196/1024 (19.14%)
7 26/1024 (2.54%)
8 1/1024 (0.1%)
The average number of projectiles thrown is 4.94.
  • Damage inflicted by debuffs such as On Fire! do not trigger the lifesteal, only the knife projectiles themselves do.
  • Because the lifesteal effect is rounded down, the Vampire Knives will not heal the player if the knives deal less than 14 damage.
  • At full speed (when first thrown), the projectiles travel at 77 mph.
  • Due to their high speed, some of the Vampire Knives' projectiles may travel through 1-tile thick walls.
  • Despite the visual effect indicating otherwise, the player gets healed immediately upon dealing damage, rather than when the ensuing red beams connect.
  • It is impossible to obtain the Vampire Knives in Corruption worlds as they lack a Crimson Chest. Instead, the Dungeon has a Corruption Chest containing a Scourge of the Corruptor.
  • Reflected knife projectiles (e.g. from a spinning Selenian(Desktop, Console and Mobile versions)) that hit the player will not trigger healing effects for the enemy.


  • Despite the Vampire Knives' very low damage, being post-Plantera, they are one of the only methods to gain lifesteal in the game, the other being the Spectre armor with the Hood. The lifesteal effect makes the weapon helpful to have as a sidearm and with a stronger weapon like the Terra Blade.
  • Some higher melee speed bonuses will cripple the Vampire Knives, as this may cause the player to only throw the knives every other swing. However, the high melee speed will make them fly faster and farther.
  • The Vampire Knives are less useful against the Moon Lord(Desktop, Console and Mobile versions) because of the Moon Bite(Desktop, Console and Mobile versions) debuff it can apply to the player, disabling the life-stealing effect of the knives.
  • The Vampire Knives are still useful with endgame gear, as no melee weapon can replace their healing effect.
  • They prove effective against numerous bosses and events. With proper preparation, it can be impossible to die.
  • While all flasks work well with the Vampire Knives, using a Flask of Ichor can directly increase damage dealt per hit, and thus increases health recovered to the player.
  • Since the Vampire Knives heal based on damage dealt, and the Crawltipede(Desktop, Console and Mobile versions)'s damage taken is multiplied by 10, the player can use this to their advantage, gaining more health than normal attacking them. However, this will make the gaps between heals longer due to how lifesteal works.


  • One of the knife projectiles will always aim at the cursor's location.
