Hey there, fellow Diablo fan! When it comes to Baal, the Lord of Destruction, you definitely want to be prepared for his icy attacks. I recommend focusing on cold resistance gear to mitigate his frosty powers. For character builds, classes with high mobility like the Amazon or Assassin can help you dodge his area-of-effect spells. In terms of lore, did you know that Baal was one of the Prime Evils alongside Diablo and Mephisto? His corrupting influence is a major theme throughout the series, so keep an eye out for clues to his dark legacy as you battle your way through Sanctuary!
