Diamond-Fist Barracks is a fairly small but important soldier-training camp in Deathym. It is fitted with a state-of-the-art mine, hostile mob prison and a bedroom. The mine is used if one of the students haven't been obeying the teacher, or if the entities need more armour.

When the training starts in January, the recruits are learnt the basics of brawling and by the end of the month they must undergo a training exercise, which involves wearing full leather armour and battling with sticks. In Febuary, the students take a break from the violence and instead sudy some of the basic overworld mobs. If the students have not studied, they will ovbiously die at the creeper trials at the start of March. After the mass of deaths, the soldiers-in-training most mine for their armour. If one person gets ful diamond but another just gets an iron chestplate, this is considered fair, for the people with better armour have ovbiously dedicated more mining-time. Until July, they study the Nether mobs and how to win a fight with them, preparing for their August trip to the nether. Up until December, they train, train & train. If the entities survive the extreme camp, they are official soldiers for the King of Deathym and his realm.

The King can then award them a KDE (Knight of the Deathym Empire) which means they can go back to Diamond-Fist Barracks, while the new trainees are in the Nether, to train for their trip for The End.
