The Kurast Undercity of Diablo 4: Vessel of Hatred offers an intense dungeon experience loaded with monsters and topped off with a unique Tribute-based reward system. As grueling as the dungeon's floors may be, you aren't precisely paid well for your efforts at the base. To maximize rewards here, you'll need to offer Tributes and enhance drops with Bargains.

Vessel of Hatred's Kurast Undercity isn't new to the Diablo franchise. Players might recall its place in Diablo 2, but the Undercity has received quite an overhaul with its reintroduction. Presenting floors filled with enemies and a formidable boss waiting at the end, it's not unlike Diablo 4's best Nightmare Dungeons. However, the Undercity's reward system sets it apart from the rest in that it's more or less powered by Tribute consumables, which can make or break the dungeon's farming potential.

How To Unlock The Kurast Undercity

Beyond The Diablo 4 Campaign

To unlock the Kurast Undercity in Diablo 4's Vessel of Hatred expansion, you must complete the campaign and reach at least Level 15. The new dungeon will become available during the "Deeds of a Champion" questline, which runs the length of the title's endgame. According to TheGamer, this quest involves slaying the Terror of Five Hills dungeon boss. You'll effectively gain access to the Kurast Undercity and its rewards upon completion of the mission.

Rush The Timed Three-Tier Dungeon

The Kurast Undercity is divided into three distinct floors. While the first two are timed, the boss arena on the third floor isn't. You'll want to consider enemy locations to make the most of your limited time before you charge ahead, as completing optional events and defeating the monsters throughout will award you more time and Attunement. Elite Monsters will grant the biggest refund to the clock, but all wins are worth it. Check your map for these icons to lay out the path ahead and make good time.

As you work to clear the dungeon, igniting Beacons will play a key role in timely progression. Once activated in the Undercity, you can take out the mobs of enemies that arrive for extra time and a significant increase to cooldown reduction. This will get you farther at a faster pace, taking you straight through the first two floors of the dungeon.

When you reach the third floor, you'll enter the boss arena. Again, these battles aren't timed, but this detail gives you some idea of how brutal the dungeon's boss fights will likely be. Steer clear of AoE attacks and replenish your health when necessary for good measure. You'll gain access to the boss's chest once you defeat the boss, though Tributes and Bargains largely determine your rewards.

Kurast Undercity Rewards

Tributes & Bargains

The Spirit Brazier outside the Undercity is where you'll make Tributes and Bargains. While optional, this is what will get you valuable rewards for clearing all three floors. Rob2628 demonstrates how you can target specific Diablo 4 items you aim to collect from the dungeon's boss chest, a feature that makes the Kurast Undercity an excellent spot to farm in Diablo 4's endgame. Tributes are most important in maximizing your rewards, but Bargains will influence the quality of drops. We've broken down the differences in how these systems work.

Tributes

GameRant explains that Tributes are classified as dungeon keys even though you don't technically need them to enter the Undercity. Instead, their primary function is to determine what kinds of drops you'll receive from the boss's chest. Naturally, more common Tributes will award less valuable loot, while rarer Tributes promise greater rewards. Apart from the ability to craft Mythic Uniques in Season 5, this poses an absolute game-changer for those aiming to get rare gear items in Diablo 4.

The only caveat here is that Tributes often boast specific requirements, and you'll need to clear the Undercity and finish its related questline to pick them up. The final quest will reward you with a few Tributes to start, but you can earn more from dungeons, public events, and additional Undercity runs. Known varieties include:

Bargains

Bargains serve to modify the loot tied to your Tribute, requiring currency, crafting resources, or a combination of the two and Diablo 4 gold' use of information. You can affix your Tribute with even more Bargains as you move through the game's difficulty levels. Remember that you can only have one Bargain active per run.

As such, utilizing Bargains is an excellent way to guarantee Diablo 4 items with Skill Ranks or Mythic Uniques. Like Tributes, however, there's a catch in making Bargains. Prices will go up the more you use them, so it's essential to progress in other areas of Diablo 4's Vessel of Hatred expansion, like unlocking all-new DLC mercenaries.
