Bosses can be found throughout the mines, with a boss room being present on each level. In a boss room is a ritual altar. By accessing the altar with its corresponding egg, a boss can be summoned. Bosses can pose a serious threat, doing a lot of damage and having a lot of health, as well as employing multiple skills to use against their attackers. Slaying a boss will grant great rewards, including a chance to drop reputation items and a guaranteed drop of a core item corresponding to their level. These core items can be used to upgrade equipment at the Blacksmith at spawn.
