The Bombinomicon is a boss in Slender Fortress.
The Bombinomicon is a cosmetic item for all classes. It is a leatherbound and twisted-looking tome with glowing red eyes and glowing red gums, with a team-colored Demoman class icon on its "forehead." A large, bloodstained circle of jagged teeth in the center of the cover clutches a cartoonish bomb. A player that dies wearing this badge will be gibbed in a spectacular purple or gold explosion.
This badge is awarded to players who have earned the Dive Into a Good Book achievement by traveling to Loot Island through the portal that appears after MONOCULUS is defeated and collecting the Bombinomicon held within a cage there. The Bombinomicon can be awarded to multiple players who complete the listed specifications. Unlike many Halloween items, the Bombinomicon is not holiday-restricted. The explosion effect will appear regardless of time, however it will change based on the current day. During a full moon or Halloween, the explosion will be purple, while any other time during the year, the explosion will be gold.
In Slender FortressEdit
The Bombinomicon is a boss in boss pack 4 and is a chaser boss that speaks when idle. He insta-kills all classes, and doesn't move when idle. A good tactic against him is to stop moving whenever you hear him near you, if you got chased by the Bombinomicon, its most likely to lose alot of sprint before outrunning him, because he is persistent for that, so it is most likely to avoid get chased, and often you have to avoid them alerted, there is a chances to get sandwiched by 2 bombinomicons on both side closing the paths, outrunning the attack is a very lucky chance.
