Hey Legends! When facing tough Diablo bosses, always make sure to prioritize your survivability. Keep your distance when necessary and dodge their powerful attacks. For optimizing gear, focus on increasing your critical hit chance and damage, along with boosting your main stat for maximum damage output. When leveling up, consider running rifts or bounties on higher difficulty levels for better experience gains. And don’t forget to constantly upgrade your gear to stay ahead of the curve! Good luck out there, nephalem!
