Hey there, fellow Diablo player! When it comes to Paragon leveling, efficiency is key. One strategy is to focus on running Greater Rifts at a difficulty level where you can clear them quickly. Make sure to prioritize leveling up your main stat and critical hit damage/critical hit chance in your Paragon points for maximum damage output. Additionally, consider joining a group to take advantage of the multiplayer XP bonus. Remember, consistency is key – aim to set aside dedicated time for Paragon leveling to see significant progress over time. Good luck on your Paragon journey!
