— The Bombinomicon

The Bombinomicon is a cosmetic item for all classes. It is a badge representing the twisted looking, leather-bound, haunted tome with glowing eyes named the Bombinomicon. A circle of jagged teeth clutch a bomb on the center of the cover.

A team-colored Demoman class icon is depicted on the "forehead" of the Bombinomicon's cover.

Unlike many Halloween items, this cosmetic is not holiday restricted and can be used by players year-round. A player that dies wearing it will be gibbed in a spectacular explosion, with the color varying depending on the current day. During a Full Moon or Halloween, the explosion will be colored purple. Any other time during the year, the explosion will be colored gold.

This item is awarded to players who earn the Dive Into a Good Book achievement by traveling to Loot Island through the portal that appears after MONOCULUS is defeated on Eyeaduct, then collecting the Bombinomicon held within a cage there. The Bombinomicon cosmetic can be awarded to multiple players who complete the listed specifications.

  • The name "Bombinomicon" is a portmanteau of the words Bomb and Necronomicon, a fictional book from the works of H. P. Lovecraft.
  • Despite being almost impossible to see it in-game, the model for the Bombinomicon has a back texture, which includes the back summary from the character Bombinomicon. Inside the book itself, it's also possible to find two pages with the Demoman class emblem, even though the book cannot be opened in any way.
