Hey there, fellow Diablo player! When it comes to defeating bosses in Diablo III, it’s all about understanding their mechanics and having the right gear and skills. Make sure to study each boss’s attack patterns and plan your movements accordingly. Having crowd control skills can also be super helpful in keeping bosses at bay.

For optimizing gear, focus on getting items that complement your build and playstyle. Look for set bonuses that enhance your abilities, prioritize critical hit chance/damage, and don’t forget about resistance stats to stay alive in tougher battles.

When it comes to leveling efficiently, don’t be afraid to bump up the difficulty for increased experience gains. Also, consider running Bounties and Rifts for a good XP boost. And don’t forget to equip a Hellfire Ring for that extra experience bonus!

Happy demon slaying and may the loot gods be ever in your favor!
