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 gained to speed up the process. Also, consider joining a group to benefit from the multiplayer experience bonus.

For optimizing your gear, prioritize items that complement your build and playstyle. Look for gear with critical hit chance, critical hit damage, and cooldown reduction to maximize your damage output. Don’t forget to augment your Ancient items with Caldesann’s Despair for an extra boost.

When facing bosses, make sure to understand their mechanics and adjust your skills and gear accordingly. Keep an eye on your positioning to avoid deadly attacks and use crowd control abilities to gain the upper hand. Patience is key, so don’t rush the fight and focus on dodging and dealing damage when the opportunity arises.

Happy hunting in Sanctuary!
