Minor bosses have been recalibrated and are now properly ‘roaming’ the maps. For those of you who take time to look around there is a chance you’ll run into 1 of 42 different minor boss monsters on any of the three maps, more than one will probably be spawned on each map at any time. They roam all over so you may need to look around to find them, you do not need a boss key to summon them. They have a chance to drop an artifact, and will usually also drop a treasure chest.
Some of them can be extremely difficult to kill, and will have very little trouble killing you, so consider yourself warned!
