The Molecular Manipulator is a craftable post-Moon Lord ranged weapon. It is the upgrade to the Nullification Pistol, and similarly uses the player's life as ammunition. The Molecular Manipulator uses 5 health for each shot and will kill the player if the manipulator takes them below 0 health. Each shot will alter its target in some way, as long as it is not a boss. The following effects can happen at an equal chance:

  • Grow 400% bigger
  • Shrink 90% smaller
  • Deal 500 more contact damage
  • Deal 500 less contact damage
  • Become completely resistant to knockback
  • Remove all knockback resistance
  • Increase defense by 20
  • Decrease defense by 20
  • Increase velocity upwards
  • Increase velocity to the left or right

Its best modifier is Unreal.




  • The amount of contact damage increase or decrease will scale with difficulty.
  • The amount of velocity increased is 1.875 blocks per second. This effect is additive, and can therefore counteract opposite motion.
    • For example, under the effect of increasing vertical velocity, an NPC that moves downwards at a rate of 3 blocks per second will still move downwards, but at a rate of 1.125 blocks per second.


  • The Molecular Manipulator will work on the Guide and the Clothier with their respective voodoo dolls equipped.
  • If the player is killed by the damage inflicted upon using the weapon, the death message "<PlayerName> was vaporized by the imbuement of his/her life." will display.
