Hey there! When it comes to Paragon leveling in Diablo, 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 equip gear that boosts your experience gain, such as Leoric’s Crown with a socketed Flawless Royal Ruby. Additionally, running in groups with other players can help you clear content faster and gain more experience. Don’t forget to allocate your Paragon points wisely – prioritize movement speed, main stat, critical hit chance, and critical hit damage for optimal efficiency. Happy grinding!
