Pandemonium Event (Uber Tristram)

Uber Tristram (Pandemonium Event) is an event that only exist in the Battle.net servers of the game (not counting D2 mods). Its unique reward Hellfire Torch is essential part of any high-end character build. This event cames to the stage as a high end content for expeirenced players to try out, bringing huge rewards and hard bosses to the table. Especially on hardcore.

Uber Tristram as players call it is actually an event called The Pandemonium Event.

To start the event you will need 3x of each Key type. Key of Terror, Key of Hate and Key of Destruction.

Key of Terror

Key of Terror drop from The Countess Act 1 Forgotten Tower level 5 in Black Marsh on Hell. Drop chance is failry high. The exact drop rate is this:

Key of Terror
Key of Terror

1 or 2 players: 7%
3 or 4 players: 9.1%
5 or 6 players: 9.6%
7 or 8 players: 9.8%

Key of Hate

The next key is Key of Hate. Drops from The Summoner in Arcane Sanctuary Act 2 Hell

Key of Hate
Key of Hate

1-2 players: 8.6%
3-4 players: 11.6%
5-6 players: 12.5%
7-8 players: 12.8%

2x Key of Hate drops from a single kill

Key of Destruction

And the last key is Key of Destruction and drops from Nihlatak in Halls of Vaught - Hell, following the quest to save Anya - Betrayal of Harrogath. Be very careful going there, especially if you are hardcore. For hardcore you need to be exceptionally strong to even try. There is a chance that Tomb Viper monsters can spawn, who can kill a 3000 HP char in a second. They have a poison based attack which without sufficient poison resist can one shot. The snakes themselves are pretty weak in terms of HP so they should be one shotable too. Also if you are a teleporter you might just skip most of them and go straight to Nihlatak but there might be a few of them surronding him. The other thing to look out for is his Corpse Explosion. There might be the posibility to go there equiped with Natures Peace Ring that prevents corpses from being raised or used. The drop chance of the Key of Destruction is pretty low especially compared to the other 2 keys.

But also expect miracles every now and then :)

Now start farming for these keys. The full set of keys needed is often called - "Keyset" or "3х3".

Now you are ready to start The Pandemonium Event. Take the keys with you and start a new game on Hell and go in Act 5. Put one of each type of key in the Horadric Cube-a and Transmute. One of the 3 possible red portals will open - Matrons Den, Forgotten Sands or Furnace of Pain. The whole reason you want to do the 3 in one game is because which portal opens first is random so you might end up with the same first portal if you do them in different games

Another advice! When you open the portals - dont open them on top of each other or otherwise you may end up not able to enter becuase they are stacked. Best way is to pick up the Cube with you and open them away from each other.

Forgotten Sands

Ok, lets say the first portal is Forgotten Sands.

Entering the portal you need to find Uber Duriel. He is many many times harder than the original Duriel. So be prepared.
The general tactic of killing these bosses is with max amount of Crushing Blow (70%). Reason for its effectiveness is that Crushing Blow drains % of the total HP of the boss. The Uber boss is 600,000 HP with 1 player in the game. With this health pool Crushing Blow obliterates them. Special spec of Paladin is used in these Uber runs - Smiters. They are primarily skilled on Smite, Holy Shield and Fanaticism. Why Paladin? Becuase with 30,000 atack rating you have more than 80% to miss an Uber but the Paladins Smite has no attack rating and always hits. So what do we gear our paladin with? Crushing Blow, Health, Max Resist and Draculus Grasp Vampirebone Gloves. The gloves are essential in this build as well as the Last Wish runeword which gives chance on hit to cast Life Tap curse. This is how paladins survive the event while others cant because they dont hit the bosses often enough, therefore not healing enough from the Life tap. A Smiter is capable of solo-ing the entire event. If you dont have a Smiter you might give it a try with 5 normal characters.
After your kill Duriel, he will drop Baal's Eye.

Furnace of Pain

Take the eye and open the next portal, again with 1 key of each kind. Lets say your next portal is Furnace of Pain.

You enter the portal and you encounter the nasty mages with the curse Iron Maiden. Beware if you are a melee class. Send your mages to kill them, then confront Uber Izual. He uses Cold, just like normal Izual but of course stronger. Kill him and he drops Mephisto's Brain.

Pick up the brain. Open your last portal, this time it will be the 3rd and only 1 left - Matrons Den.

Uber Andariel lives there but this time she is called Lilith. The most dangerous of all Ubers. Very hard hitting physical strikes, as well as lethal Poison. Mercs are easily killed in this encounter. Nasty fact is that there are a lot of succubuus that cast Amplify Damage, which doubles all Liliths damage. Try to clear them before engaging her. In the end she drops the last part - Diablos Horn.

Now you have all three parts of the Ubers called the Organ set. You can even sell them, they go expensive on the market. But we are here to use them so put them into your Horadric Cube and transmute. Another red portal - Tristram. This is where it gets serious.

So before you go in, couple of things to have in mind what awaits you inside. The Organ sets consits of the parts of the three Ubers you will face in Tristram (Uber Mephisto, Pandemonium Diablo (Not Uber Diablo) and Uber Baal) but this time you wont fight them 1 by 1 as you did so far - they will be all together on a small area such as Tristram. Experienced players would try to pull them 1 by 1 successfully. Important to remember is to start with the deadlies of the three - Mephisto. He uses Conviction aura which will destroy your resistences... with a lot. It's not rare to die fighting him. Diablo and Baal are not that dangerous. Pull Mephisto into the top right corner of the map and kill him before going to the center where Baal and Diablo are.

Uber Mephisto

He has a very high level of Conviction aura which will bring your Max resists to negative valies making you extermely vulnerable to his attacks. He also summons Skeleton Mages that use elemental attacks. The only way to really leech HP from him is to use Life Tap. He uses spellsl ike Lightning Bolt, Charged Bolt, Poison Nova, "Skull" Missile, Frost Nova, Blizzard and Conviction Aura.

Uses Armageddon skill too.

Pandemonium Rewards

Kill them and claim your reward - Hellfire Torch - a unique Large Charm. You can only wear 1 Torch so if all your characters fighting the Ubers have torches, you will need to bring in mules. The order in which you kill the Ubers does not matter, the last one you kill will drop the Torch. Together with the Torch they drop Standard of Heroes which is something like a trophy from the battle. Doesn't serve any purpose but to brag with it. Probably wont need to pick it up at all.

Now that the hard part is over you can take a deep breath and identify it. What stats it will be? For what Class?
