The last time I played my Barbarian, Zeta, she was in Act I of Nightmare mode. By the time I’d stopped playing, she had reached level 34. Her (rather short this time) adventure continues from there!
I decided to return to the Cemetery of the Forsaken just to see if the dungeons had any other achievements for me. I got Jar of Souls (my favorite) a while back, and I got The Matriarch’s Bones the previous time I played.
