Kurast Undercity

The Kurast Undercity, introduced in Diablo 4's "Vessel of Hatred" expansion, is a multi-level, time-attack dungeon beneath the city of Kurast. Players race against the clock, defeating enemies and completing events across three distinct districts to reach unique bosses. Success is rewarded with valuable loot, scaling with your performance.

The difficulty of the Undercity will always be in line with the difficulty you are playing on, i.e Hard, Penitent or Torment 4 so it will be as appropriate during leveling up as it will be at endgame.

Unlocking the Undercity

On completion of the Vessel of Hatred campaign, Ormus will ask you to undertake a few small quests which introduce players to endgame content, including the Undercity.

To gain access to the Kurast Undercity, start by completing the "Reunion" Map quest from the Vessel of Hatred Campaign, ensuring you are Level 15 or above. This accomplishment will activate the Priority Quest "The Kurast Undercity," Map beginning at the Kurast Bazaar. From there, you will navigate through a series of tasks, moving between different areas of the city and the Undercity itself, tackling challenges in each district. The quest chain ultimately leads to a confrontation with Alia, marking the final step to fully unlock the dungeon and complete the storyline.

Accessing the Undercity

The entrance to the Undercity is different to the one you used in the Campaign Quest (Fundament of Faith Map. It is still in Kurast but it's on the eastern side. The dungeon entrance portal will appear once you have activated the Spirit Brazier in the same area.

Tribute and Bargain

Both Tribute and Bargain offerings at the Brazier allow you to customize the kinds of rewards you want for completing the Undercity.

Offering a Tribute & Bargain at the Spirit Brazier

Tributes can be earned by completing activities such as Nightmare Dungeons, events, Whispers and Undercity runs. They are fairly rare drops. These Tributes can be offered at the Spirit Brazier to target specific rewards for your next run, but doing so will also increase the challenges you face. The difficulty of these challenges scales with the quality of the Tribute and the current difficulty level of your world. Higher-quality Tributes grant unique bonuses, such as Increased Experience Gain or awarding Runes upon completion. To claim these bonus rewards, you must reach at least Rank 1 Attunement, with successive ranks boosting the rewards even further.

After placing a Tribute, you can select a Bargain to customize your run's rewards, such as increasing the chances of obtaining items with specific affixes or guaranteeing certain types of drops. Activating a Bargain requires resources like crafting materials or gold, so choose based on your current goals and available materials.
