This is a series of additional quests which were added to the game by a later patch. It is designed to be played by high level characters and represents a very difficult challenge for all. In the Pandemonium Event, there are three keys which must be recovered.
The first key can be found with the Countess from the fourth quest in Act One; the second is located with the Summoner in the Arcane Temple in Act Two, while the third key can be found with Nihlathak, from the Lords of Destruction expansion pack. Each key can then be used in the Horadric Cube to create portals to the Matron’s Den, Forgotten Sands and Furnace of Pain areas. To do this, you'll need to be in Harrogath, otherwise it won't work.
On each of these levels characters will encounter a stronger version of the original Diablo II game’s bosses – Uber Andariel (Lilith) in the Matron's Den, Uber Duriel in the Forgotten Sands, and Uber Izual in the Furnace of Pain. When defeated, each will drop one of three special items: Mephisto’s Brain, Diablo’s Horn, and Baal’s Eye.
When placed together in the Horadric Cube and transmuted, these items will open a portal to Uber Tristram where the toughest battle awaits – characters will face up to Uber Mephisto, Uber Baal and Pandemonium Diablo; three versions of the original boss monsters, only much more powerful!
Once defeated, the character will be rewarded with a unique large charm - the Hellfire Torch. This grants the bearer the following bonuses and is dropped by Pandemonium Diablo. Characters need to be level 75 or above to be able to use this charm.
