The last 10 or 15 times I've played, the game has always gone exactly the same way: I get to level 80 without dying much, and then I always die before level 90. I know I just need more practice... except that practicing those levels means I need to spend nearly an hour playing through the rest of the game! There's not much for me to do -- I've completed every PD I can reach (except Hell!) and every quest that I can, except the ones where I'm waiting for coeff.5 items.
Do you experienced players have any advice? Are there any earlier PDs that are good practice for levels 70-90? Or anything else I can do to keep the first 70 levels from being a repetitive grind?
