The Cursed Captives achievement says to free 6 prisoners in 120 seconds in the Cursed Hold (which is obviously Act I).
I have tried this several times and always been quite over 2 minutes. The distance just seems too great to cover in so little time, especially if you get some really annoying champions like wallers or jailers.
Do I need to just hope for a better pseudo-random layout and prisoner placement? Do I need to boost my movement speed as much as possible and just gun it? Would this be easier with any specific class? Is this possible on multiplayer and, if so, is that perhaps the only way to complete this achievement? In short, how do I get this achievement?
