Hey fellow Nephalem! When facing bosses in Diablo, it’s crucial to understand their mechanics. Study their patterns and know when to dodge or use defensive skills. For gear optimization, focus on items with stats that complement your build. Don’t forget about sockets for extra bonuses. Efficient leveling involves running bounties and rifts for experience. Also, playing on higher difficulty levels grants more experience. Good luck on your campaign, and may legendary loot be ever in your favor!
