Angered by his previous failures to destroy the small groups of adventurers that stood in his way, Diablo has reincarnated himself once again at his absolute maximum strength. The demonic ritual which caused this ultimate reincarnation was long thought to be impossible, even by the most learned arcane scholars. Now, the Lord of Terror sets his plan in motion, and he and his brothers will unleash a new wave of Pandemonium upon the world of Sanctuary...[1]

Pandemonium Diablo is found only in Über Tristram, at the culmination of the Pandemonium Event. Vastly stronger than the Diablo players encounter at the end of Act IV, Pandemonium Diablo possesses far higher statistics, including hit points, damage, and resistances, as well as several new skills.

Beware his Bone Prison; it is difficult to destroy and can imprison a player or minion for quite a while. His Red Lightning Hose attack deals half physical, half lightning damage. He also casts Armageddon.

The biggest difference the player notices is that this version of Diablo now has much higher life, much higher resistances, more powerful attacks, and he also regenerates life at twice the normal rate.


  • Fire Nova - An expanding ring of fire, similar to his Act IV appearance.
  • Red Lightning Hose - Another move borrowed from his Act IV encounter, this pink spray of doom deals half lightning and half physical damage.
  • Cold Touch - Chills and slows players without proper equipment. (Can not be frozen.)
  • Fire Wall - Just exactly like the Sorceress's spell of the same name, this creates a very damaging wall of flame to torment heroes foolish enough to stand in the fire.
  • Firestorm - Diablo's special moving firewall attack, this snakes along and deals huge damage to anything nearby.
  • Bone Prison - Diablo targets stationary characters and especially town portals with this form of entrapment.
  • Charge - Dropping to all fours, Diablo races in to close the distance. He is highly vulnerable in this mode, losing his blocking, so quite a few hits can be scored if he does it while chilled or slowed by a Decrepify curse.
  • Armageddon - Just like the Druid skill, this rains fireballs down all around Diablo, damaging any players in the vicinity.


Pandemonium Diablo in Uber Tristram

Pandemonium Diablo is not the same as Über Diablo (also known as the Diablo Clone). Pandemonium Diablo is one of the three brothers spawning in the Pandemonium Event - Über Tristram, while the Diablo Clone is a single boss spawning after enough Stones of Jordan have been sold on a given server. This confusion is due to the Pandemonium Event being introduced after Über Diablo has already been added, and therefore this name was taken.
