Season 14 has pushed Diablo 4's endgame into a different rhythm, and the part most people notice first is the key system. Betrayer's Husks are gone in name, yet the item still matters, just under a new label. If you are already sorting loot and boss runs, it helps to keep an eye on your D4 items stash, because Superior Lair Keys now sit right at the centre of high-end farming. The big change is not just cosmetic. It changes where you go, what you chase, and which fights are worth your time.
The old Betrayer's Husks tied everything to Belial. That made sense for a while, but Season 14 adds another top-tier Lair boss, so the key has been renamed to Superior Lair Keys. That rename is more than a tidy-up. It tells you the key is no longer a one-boss oddity. It now opens reward caches for multiple high-end encounters, including the new seasonal boss. In practice, that means more reasons to farm, and a cleaner path for players who want Mythic Unique drops without wasting runs on the wrong content.
There are still two reliable ways to get them. One is the old Belial ambush after opening a Lair Boss cache in Torment, which stays familiar for veterans. The second is much better for steady farming: the Deathtoll Chamber. You reach it through Pandemonium Ruptures and Realmwalker encounters, and that route feels a lot less random. Normal Ruptures pop up in the open world, Surging Ruptures appear during Helltide, and Colossal Ruptures guarantee a Realmwalker. That chain matters because the chamber gives a far more consistent flow of key drops than waiting around for a surprise boss ambush.
The practical part is simple. Use two Superior Lair Keys to open Belial's Hoard after the fight, or spend them on the new seasonal boss cache in Zarbinzet. If you are pushing for gear, the seasonal boss is the one people keep coming back to. It drops better Mythic Uniques and upgrade currency than most other activities, so players who plan their farming around that fight usually get more out of their time. A few habits help too: finish Ruptures with Mastery when you can, intercept the orbs from Gravehounds before they feed the Exarch, and do not ignore random Rupture Goblins. They can open more chances than you might expect.
Here is the part most players end up following anyway: stay in Torment, chase Ruptures during Helltide, and treat Realmwalkers as your shortcut to the chamber. If you like lists, this is the short version. Keep Torment farming on, enter the Deathtoll Chamber whenever it opens, kill Gravehounds fast, grab the orb drops before they reach the Exarch, and save your keys for the boss that gives the best return. For anyone building toward endgame loot, that is the route that feels best, and it is also the route that saves the most time. If you want to keep the process smooth, many players will buy Diablo 4 materials only after they know which boss they are targeting, because that keeps every key tied to a real reward.
