The Brain Scrambler is a Hardmode, post-Golem enemy that appears during the Martian Madness event. It fires green laser projectiles, at a maximum fire rate of once every 0.67 seconds (40 ticks[1]),[2] which have a chance to inflict the Confused debuff.


  • It is recommended to use ranged or high-knockback weapons against it to keep it away, and to delay the travel of its weapon's projectiles.
