Tips
  • Sorceresses can teleport directly to the Chaos Sanctuary.
  • Oblivion Knights, found in the Chaos Sanctuary, can cast curses like Amplify Damage, Decrepify, and Lower Resist, making you vulnerable.
  • Focus on acquiring high Fire resistance when preparing to fight Diablo, as his most common and dangerous attacks are fire-based.
  • Lightning resistance is also beneficial to mitigate his Lightning Inferno attack.
  • Immunity to freezing is helpful, especially for melee characters.
  • If playing a caster, lure Diablo away from his spawn point to circle him and avoid most attacks.
  • Melee fighters must be highly aware of Diablo's movements to dodge his powerful attacks.
  • Diablo's attacks include Flame Nova, Fire Wall, Flame Torrent, Lightning Inferno, Freezing Touch, Charge, and Bone Prison.
  • Lightning Inferno is his most damaging attack; run to avoid it and watch for him to rear back before casting.
  • Bone Prison can trap you if you create a Town Portal too close or run away frequently; Sorceresses can use Teleport to escape.
  • The Chaos Sanctuary is an area level 85 (aLv85) where nearly any item in the game can drop, making it a lucrative farming location.
  • It's possible to bypass most enemies by teleporting, killing the seal guardians, and then confronting Diablo.
  • Diablo himself can drop most items in the game and is quicker to kill than Baal.
  • Good resistances are crucial for surviving the Chaos Sanctuary, particularly against Oblivion Knight curses.
