A friend of mine and I recently started a new project where we are only playing Hardcore seasonal toons through the campaign - at least to start. It's been a long time since either of us have waded through the story, so we're having fun. I also made a hardcore seasonal farmer to help both of us since all 3 toons are Monks and I'll be able to craft gear. So, the question is - the farmer got the Cube in Adventure mode, but I forgot how it's acquired in campaign mode. Or is it not even an option?
