The Kurast Undercity has changed significantly after the latest hotfix, especially for players who have been looking for more reliable ways to improve their endgame characters and collect valuable D4 items. The update gives Mythic Tributes of Armaments a much clearer purpose, making high-level Undercity runs more rewarding for players who are prepared to handle the toughest Torment difficulties.

For a long time, farming D4 items through difficult endgame activities could feel inconsistent. You could spend time preparing a run, use an expensive Tribute, and still finish without getting anything that justified the effort. The new changes make the Undercity more attractive because Torment 10 and Torment 12 now offer different but meaningful goals for players at different stages of progression.

T10 and T12 Now Serve Different Players

The biggest change is how Mythic Tributes of Armaments work at the highest Torment levels. Torment 10 now offers a heavily increased chance of receiving a Mythic Unique, making it a useful option for players with strong builds that are not quite ready to handle T12 comfortably.

This is important because pushing difficulty is not always the same as improving efficiency. If your character can clear T10 quickly but struggles to survive or takes much longer at T12, the lower difficulty may still be the better farming choice. A fast, consistent run can produce better results over a longer session than repeatedly failing or slowing down at the highest level.

Torment 12, however, is where the new system becomes much more interesting. With the correct Attunement rank, completing a Mythic Tribute run at T12 guarantees a Mythic Unique. For players with fully developed builds, this changes the Undercity from a high-risk farming activity into a much more predictable endgame loop.

Build Preparation Matters More

The hotfix rewards players who prepare before entering the dungeon. Your damage is obviously important, but survivability and clear speed also have a major impact on your overall efficiency.

A character that can comfortably handle T12 should focus on completing the run without unnecessary delays. The goal is not simply to kill everything as quickly as possible. You also need to manage your Attunement and make sure you have enough time to reach the desired reward level.

For players who are still progressing, T10 provides a useful middle ground. You can benefit from the improved Mythic drop rate while continuing to strengthen your character for future T12 runs.

Use Gutter Filth to Increase Rewards

One of the most interesting parts of the updated farming strategy is the Gutter Filth node on the activity skill tree. Players who plan to spend a lot of time in the Undercity should consider unlocking and activating this node before starting their runs.

With Gutter Filth active, activating beacons inside the dungeon can create a chance for Portal Pranksters to appear. These treasure goblin-style enemies are more important than they might initially seem.

Killing a Portal Prankster can create an additional bonus chest in the final arena. If you manage to trigger several of them during a T12 run, the number of reward chests can increase considerably. In especially successful runs, players may end up with two, three, or even four Mythic Unique items.

That outcome is not guaranteed every time, but the possibility gives you another reason to pay attention to the dungeon mechanics rather than simply rushing toward the end.

Manage Attunement Carefully

Attunement should be one of your main priorities during a Mythic Tribute run. You want to maximize your reward level while keeping enough time available to complete the dungeon successfully.

Afflicted monsters that extend your timer deserve particular attention. Killing these enemies can give you additional time to build Attunement and continue exploring the Undercity without feeling rushed.

This also means that blindly following a speed-farming strategy may not always be ideal. The best route is the one that balances speed, Attunement, and bonus opportunities. If you ignore important time-add enemies, you may reach the final arena without the reward level you need.

Building a Supply of Mythic Tributes

Once Mythic Tribute runs become part of your regular endgame routine, finding enough Tributes becomes an important part of the process. You can create one Mythic Tribute of Armaments by combining five Legendary Tributes of Armaments through the Horadric Cube.

Whisper Caches can also help. When completing Tree of Whispers activities, look for greater caches that specifically provide dungeon keys. These can gradually increase your supply while you work on other objectives.

Lair Bosses are another useful source of endgame rewards. Bosses such as Lord Zir, Grigoire, and the Beast in the Ice can provide treasure hoards that contribute to your overall farming resources.

Choosing the Right Farming Strategy

The hotfix does not mean that every player should immediately move to T12. The best difficulty depends on your character's actual performance. If T10 is comfortable and fast, it remains a strong option for improving your Mythic Unique collection while preparing for harder content.

Once your build can reliably clear T12, however, the guaranteed Mythic reward makes it much easier to justify spending your valuable Mythic Tributes there. The combination of guaranteed rewards and bonus chests can make each successful run feel considerably more worthwhile.

For players who have reached this stage, the updated Undercity is a much better place to focus on endgame progression. If you want to supplement your own farming with additional resources, you can also buy D4 Gold from U4N to help support your wider gearing and crafting plans without interrupting your regular gameplay routine.

The main lesson from the hotfix is simple: preparation now matters more than ever. A strong build, efficient Attunement management, Gutter Filth, and smart use of Portal Pranksters can turn a single Tribute into a very productive run. For players who enjoy optimizing their endgame routine, the new Undercity system gives D4 a more reliable Mythic farming path.
