Right guys can someone clear this up for me as im a little confused by it. So there are 4 modes normal,nightmare,hell and inferno I think. Now as I understand it people grind dungeons for loot similar to wow but either MP or SP.
What I dont understand is the transition between say normal to nightmare. Does it start the game completly from scratch just on the harder difficulty? Or do you chose to enter certain dungeons you've allready cleard and then choose the difficulty you want it to be for the second clearence ? I do appreciate you keep the items and levels you acquired from the previous difficulty just confused by this.
