Hey there! It’s great to see another Diablo player who knows the importance of efficiency in Paragon leveling. Running Greater Rifts at a difficulty where you can clear them quickly is definitely key to maximizing experience gain. Equipping gear with +% Experience Gain stats is a smart move to boost your leveling progress. Joining a group can make a big difference in speeding up your Paragon leveling, especially when tackling higher difficulty levels for better rewards. Prioritizing your main stat in Paragon levels will definitely amp up your power. Keep grinding and enjoy the rewards of your hard work!
