The Brain Monocle is a misc equipment that can be obtained in the Nightmare. It can be purchased from MANAGER SUPREME or No-Legs at a price of 500,000 gold. Other viable methods of acquiring the Brain Monocle include the following:
In appearance, it is a gray monocle that is attached to the player's 'brain'. The end of the monocle glows dimly in a pinkish-red color, like glowing blood. It is also encased in glass and attached to the back part by the chain from the monocle's 'foundation' supports.
When equipped, the Brain Monocle will provide 30 additional points to both magic and ranged damage-types, increasing the number of damage inflicted on opponents while using ranged and/or magic weapons.
- The Brain Monocle provides the highest magic bonus out of all misc equipment as of the Ratboy's Nightmare Update.
- Despite being a monocle, it is worn on the forehead, not at eye level, and it is not aligned with the eye effects gained from equipment such as the Scorched Soul's Ring.
- When visible, the player is able to see the Brain Monocle's chain while in first person.
