Right now my run is about 40 minutes long and everage of 7 million xp per run. I am using XP stone on helm/3 gears with +72 xp per kill bonus. Sorry no signet or hellfire. Trying to get keys in third act 3. I have 3 act one keys/ 1 act 2 keys/ and 2 act 3 keys and no blacksmith plans yet.
If you are Paragon Level 40+ Please let me know your strategy/advice. How many hours / level did it take you to get to level 25 to level 40+
