With Dean McKenzie's current strength, any monster below the third-turn level is fair game for him to slaughter.
A first-turn Rare Template like the Corpse Witch Belt sure has powerful abilities, but in the face of Dean, it's no different from standard riff-raff.
After slaying the Corpse Witch Belt, Dean brought it and its five followers into the Land of Bone.
Upon entering, Dean found himself in a chaotic Land of Bone.
It couldn't be helped, these past two to three days, Dean stuffed a thousand monsters into the Land of Bone.
A thousand monsters, most of which had been seriously wounded by Dean, but that didn't mean they won't try to stir up trouble, right?
After all, these monsters are level 30 elites or even Excellent Templates. While Dean inflicted damaging blows, he still had to be in control so they wouldn't die, leaving him some reserves, which meant some monsters still had some strength left.
