I beat it at lvl 4 with me (Ranger), Lae'zel, Shadowheart and Astorian. But, I brought help. I purchased the aid of the 3 ogres you find at the Blighted Village. I called them in to help me fight the Minotaurs, and the Bullete. They aren't great, but they pull attacks for about 3 rounds or so instead of decimating my party. Gave me a lot of solid damage the first fight. It then flees. The second fight I finished it.
Im a goody goody I killed the ogres! lol
