Über Mephisto resides within a secret realm where, together with his brothers, he commands three generals. These generals, Lilith, Duriel, and Izual, conduct operations from their own hidden realms. Adventurers powerful and clever enough to unravel the secrets behind this "Pandemonium" will obtain knowledge and treasure used only by the most powerful agents of sin.[1]

Tips and Other Additional Information

Über Mephisto has become far more powerful since your last encounter. If Pandemonium Diablo is the tank and Über Baal is the support caster, Mephisto is the artillery. Beware of his long range attacks, such as Lightning, Charged Bolt, and Blizzard. His "Skull" missile and Blizzard attacks are especially dangerous because they will slow you down, allowing Baal's Hoarfrost and Diablo's Armageddon to wreak havoc. Bring gear which prevents you from being frozen. He has an powerful level 20 Conviction aura.

Cold and Lightning Resistance helps a lot against Mephisto.

You cannot steal Life or Mana from Über Mephisto. Über Mephisto is also immune to Poison and Lightning.

Mephisto uses the following Skills: Lightning, Charged Bolt, Poison Nova, Bone Spirit, Frost Nova, Blizzard and Conviction.

Being a level 110 monster with 3360 Defense, Über Mephisto is very hard to hit, even with high Attack Rating. To achieve mere 60% chance to hit, a level 80 Paladin requires 5,722 Attack Rating, growing exponentially. Achieving 95% chance to hit would require an impossible 1,340,640 Attack Rating. Due to this, an effective way of dealing with Über Mephisto is using an attack that always hits regardless of Attack Rating, such as Smite or Guided Arrow.

Zero Drain Effectiveness means that Life steal doesn't work on Über Mephisto at all. However, cursing him with Life Tap allows players to leech life from him. This makes Dracul's Grasp gloves or Exile shield an invaluable item to bring to battle if your party lacks a Necromancer. Sometimes, a Wand with Life Tap charges is enough to curse him, as it can be wielded by any character and can be bought at NPCs.
