I've leveled that fast before. I spent a lot of time in the game between the two days, but it's doable. Have you played Master III or above, single-player? Not easy. I have great Demon Hunter items, but even Master II isn't worth my time because of how long
it can take to kill certain enemies. And those purple beams of death... I'd offer to do some trading, but I'm really only looking for a (two-socket) Manticore and a (Rapid Fire-boosting) Dead Man's Legacy as well!
