Hey there! When it comes to Paragon leveling in Diablo, efficiency is key. Focus on farming high-density areas like Halls of Agony or Fields of Misery on higher Torment levels for better experience gains. Make sure to equip gear with experience-boosting stats and run Greater Rifts for gem upgrades to enhance your power.

For boss fights, make sure to study their mechanics and adapt your build accordingly. Utilize crowd control skills, movement abilities, and burst damage to take them down quickly. Prioritize survivability stats on gear to withstand their attacks.

When optimizing gear, pay attention to set bonuses and synergies between your skills. Look for items with critical hit chance, critical hit damage, and elemental damage bonuses to maximize your damage output. Don’t forget to augment your Ancient gear with Caldesann’s Despair for additional stat boosts.

Stay persistent and keep pushing higher Greater Rift levels to gain more Paragon levels and improve your character’s power. Good luck out there in Sanctuary
