The Four Forcemen are a group of challenging bosses in the Tower of Barbs. They are only available on Wednesdays and Sundays. Each of them has three different difficulties: NORMAL, HARD, and NIGHTMARE. Each difficulty is on a specific floor, and may be fought for free once per day, for a total of 12 free fights every day they re-appear. Afterwards, the difficulties will cost 5K, 30K, and 100K KC per fight, respectively. Each of them can drop Blueprints for their weapons and armor, as well as the 44CE Metals needed to upgrade them. However, Normal will not drop any Forcemen Blueprints, and 44CE Metals will only drop from Nightmare. Generally, they are intended to be fought after defeating the 40F Don, as the Forcemen will likely make quick work of the player otherwise.
