The Dungeon-Masters are map-killers. Today they destroyed sfan5's house and a part of my light house. We killed them under our houses for two hours. After sfan5 left, a second one respawned in the rest of his house and started devestating it even more.
It has no sense to fight them - they are total mapkillers. The exlosion effect can even kill your chests (locked and unlocked) and so everything what was in it.
