General Murius

General Murius is the leader of Markwin's army of Minotaurs. He can most often be found supporting the minotaur troops in Mintwallin. You can use an Obsidian Knife on his corpse in order to get a Minotaur Leather.
He is thought to be an allusion of General Marius, who was a general in Ancient Rome.

General Murius never retreats.

Another way to kill it is with Firebomb runes (look at the screenshot). Stand in the Lvl 30 door in Markwin's room, firebomb the fields infront the door, wait for General Murius to come close, go behind the door, wait for General Murius to go few steps away, lure him again by going in the door, and so on. General Murius will run through the fire all the time and after a while he will die. You only need lvl 30 to enter the door, but other doors would also work.
