Hey fellow Nephalem! When facing bosses in Diablo III, it’s crucial to focus on your build and gear. Make sure to have a good balance between offense and defense. Learning boss mechanics is key, so pay attention to their patterns to dodge attacks effectively. As for gear optimization, prioritize critical hit chance, critical hit damage, and elemental damage bonuses that suit your skills. When leveling, focus on completing bounties and rifts for efficient XP gain. And don’t forget to regularly upgrade your blacksmith and jeweler to craft powerful gear! Good luck in Sanctuary!
