Pandemonium and endgame bosses
Pandemonium Event and Hellfire Torch
The Pandemonium Event turns three sets of Hell keys into organs and a final Uber Tristram encounter that rewards a Hellfire Torch.
WHERE & HOW TO FARM
Pandemonium Event and Hellfire Torch
Harrogath in Act V for Cube portal creation, followed by the randomly selected mini-Uber areas and Uber Tristram.
Before you go
- Collect Keys of Terror, Hate, and Destruction on Hell difficulty.
- Have enough survivability and damage for the mini-Ubers and final bosses.
- Carry the Horadric Cube and keep keys and organs organized.
Farming steps
- Farm three keys of each type from Countess, Summoner, and Nihlathak, counting only actual drops.
- In Harrogath, transmute one key of each type to open a random mini-Uber portal.
- Open the portals from separate key sets in the same game when possible, reducing the chance of duplicating a destination without access to all three organs.
- Defeat the mini-Uber in each portal and collect its organ: brain, eye, or horn.
- When all three organs are collected, transmute them in Harrogath to open Uber Tristram.
- Defeat Uber Mephisto, Uber Diablo, and Uber Baal, then pick up and identify the Hellfire Torch.
- Prioritize resistances, a Life Tap source, and Crushing Blow for the endgame fights; Magic Find does not help the key hunt.
- Keep the portals and organs in one session so you can complete the chain without rebuilding intermediate progress.
Repeat, collect and use
Repeat with fresh key sets for another attempt; portals consume their ingredients, organs are collected from the mini-bosses, and one Torch is awarded per completed Uber Tristram run.
Common mistakes
- Opening all portals from a single key set; each portal needs a full set of three keys.
- Transmuting outside Harrogath; use the Act V town for portal creation.
- Entering Uber Tristram without suitable defenses; prepare for the bosses’ damage and aura pressure before consuming the organs.
When to stop or switch
Stop after receiving a Torch that meets your character’s needs, or pause before the organ step if you need to improve gear for the final encounter.
