I'm starting to wonder why I'm even doing this; I finished the game and what's the use in grinding. I guess it's because I originally set out to complete all five acts in all three difficulty levels, so I'm on a bit of auto-pilot.
Now that I'm actually doing it the fun has been leaching out of it. I was especially not looking forward to meting up with Duriel again - last time it took like 20 deaths to get past. But now that I have better area effect spells and a defensive mercenary, I only died once.
So we grind on.
