Boss Mobs are Hostile Monsters added by Deadly World. Bosses have randomly generated names, causing them to never despawn. They are spawned on world generation, and as such, will not spawn afterward. They are spawned in caves anywhere below layer 42, and will usually be equipped with unique weapons and armour that will drop on death. These pieces of equipment are usually very well enchanted and can sometimes have enchantments that can normally only be obtained through creative mode.
