Hey there! When it comes to Paragon levels in Diablo, it’s all about maximizing your character’s potential. Focus on balancing your main stats like Strength, Dexterity, and Intelligence based on your class. Allocate points in Vitality for survivability.

For boss fights, make sure to have the right gear with high damage output and survivability stats. Always be on the move to avoid boss attacks and use crowd control skills effectively. Knowing the boss mechanics is key to a successful fight.

When leveling efficiently, consider running rifts or greater rifts at a difficulty where you can clear them quickly. Grouping up with other players can also speed up the process. Prioritize killing elite packs for more experience.

Overall, consistency is key when grinding for Paragon levels. Keep pushing higher difficulties as you grow stronger and optimize your gear to tackle tougher challenges. Happy hunting in Sanctuary!
