Epic Bosses

Prior to Admiral Hateheart, the same knights were used for both Epic Boss fights and normal fights. This meant that players had to avoid fighting on the map if they wanted their knights to be at full hitpoints when attacking the epic boss. Also, the boss does not vanish immediately if you lost the fight.

Beginning with Admiral Hateheart, the epic boss received a new reward track. Each kill of the boss advanced you one step up the track, and levels 1, 3, 6, 10, 15, 21, 28, 35, 43, 51, and 60 gave prizes. (The "reward level" bosses had the stats of a boss several levels higher.) Every epic boss fight begins with all of your knights at full health, and damage to your knights from the fights does not affect your knights on the map. Once summoned, the boss will stay around for 2 hours or until killed, allowing you to come back and finish it off in a second fight if you haven't killed it on the first attempt.
