Boss Fights Edit
Boss fights have a rare chance to occur. This gamemode is related to juggernaut, but instead of a player, it is an NPC. As of now, there are only two bosses, Siegmund and Neflhelm. Neflhelm only spawns in winter, and has a 1% chance of spawning, but unlocks the Cryo class on defeat. Siegmund has a much higher chance of spawning, but does not give anything on defeat. Apart from something to be proud of, of course.
Boss fights are not a test of skill, but a test of server co-operation. I have found that it is quite necessary to have at least one Abyss, a few tanks, and some rangers. Or, ATAR. I have found that this almost always results in victory.
