These 24 tracked materials support different goals: encounters, respecs, quest progression and utility recipes. They are not interchangeable. Before farming, identify the output you want and check the edition and difficulty requirements.
Plan complete ingredient groups
For the Pandemonium Event, keep Terror, Hate and Destruction keys as a balanced group. Opening all three Mini Uber portals in the same game avoids repeatedly opening the same destination. Organs belong to the later portal step; a key is not a substitute for an organ.
A Token of Absolution uses all four different essence types. Reign of the Warlock's five-statue encounter is a separate system and must not be confused with the three-key event. The tracker records quantities, not quest flags, portal state or whether your character can safely finish an encounter.
Keys
Key of Terror
Dropped by The Countess in Tower Cellar Level 5 in Hell. Cube one Terror, Hate and Destruction key in Harrogath to open a Mini Uber portal. Three of each key lets you open all three portals in the same game. Magic Find does not improve key drops.
Key of Hate
Dropped by The Summoner in Arcane Sanctuary in Hell. Start from the Arcane Sanctuary waypoint and check its four branches. Key odds depend on player count; Magic Find does not improve key drops.
Key of Destruction
Dropped by Nihlathak in Halls of Vaught in Hell. Beware Corpse Explosion. Find Item cannot be used on Nihlathak for a second key roll.
