The dungeon, exclusive to ‘s first enlargement, is a time-attack-style challenge. Dive deep into the depths of Kurast, the capital city of Nahantu, navigating its treacherous dungeon at breakneck speed while efficiently eliminating formidable foes to maximize earnings and accelerate the accumulation of attunement points, ultimately increasing the potential for a bountiful reward.
We will provide guidance on unlocking the Kurast Undercity exercise, strategies for enhancing loot rewards, and techniques to prevent running out of time.
To unlock Kurast Undercity in Diablo 4, you’ll need to progress through the game’s storyline and complete a series of tasks. First, you’ll need to reach Act III and defeat the Prime Evil, Andariel. This will grant you access to the Harrogath town, where you can find the first clue to unlocking Kurast Undercity.
From there, you’ll need to complete the “Lost City” quest, which involves finding a series of ancient artifacts scattered throughout the world. These artifacts hold the key to unlocking the secrets of Kurast Undercity, and will ultimately grant you access to this hidden region.
Beneath the town of Kurast lies the infamous Undercity, a labyrinthine realm of dark alleys and crumbling architecture, where the whispers of the damned echo through the shadows. To proceed with this exercise, you must advance your marketing campaign until you reach Kurast, complete some tasks for the council there, and then move forward. Across the boss fight?
A member of the council will subsequently provide training on the fundamental techniques required for constructing the Kurast Undercity model. As players near the endgame, they can leverage various modifiers, without delving into specifics here. Throughout the quest progression, new areas will become accessible for exploration.
You can try farming the entrance boss, Delsere’s Guardian, repeatedly for a chance at the extra 15 seconds of time. Additionally, attempting the Council of Seven and defeating each councilor can reward you with an additional minute on your clock. If you’re having trouble finding these areas, consider exploring the various tombs and temples scattered throughout Kurast Undercity, as they often contain valuable items and a bit of extra time.

Kurst Undercity is a challenging time-attack dungeon, where players start alone by default, requiring skillful navigation to overcome its treacherous terrain. To fully reward yourself, you’ll need to conquer multiple dungeon levels before defeating the formidable boss waiting at the end. Unless you’re significantly overleveled for the current problem, this course of is likely to consume more than 100 seconds, potentially prompting the dungeon’s auto-kick feature and truncating your run prematurely?
Throughout each level of the dungeon, numerous Grinders (resembling enormous hamster wheels) are scattered. Objects and enemies bearing an orange hourglass symbol next to their icon on the map indicate that they are time-sensitive. Defeating monsters or destroying constructions rewards players with time refunds, potentially propelling them beyond the initial 100-second timer. Despite their elite status as monsters and high health levels, a crucial consideration arises: will the time invested in defeating them yield sufficient returns to justify the effort?
By stacking multiple Monsters without hesitation, you can unleash a devastating combo that deals area damage and wipes out enemies simultaneously, granting you a significant time advantage with minimal investment.
To optimize your Kurast Undercity loot chests, consider implementing these strategies:
Experiment with different class builds and playstyles to uncover the most desirable drops.
Amass a comprehensive collection of unique items and re-roll them for potential upgrades.
Invest in crafting materials and recipes to enhance your character’s capabilities.
Participate in various game modes, including bounties and greater rifts, to increase your chances of acquiring valuable loot.
Engage with the community and share knowledge on optimal builds and strategies to maximize your Kurast Undercity rewards.

Throughout the entirety of Kurast Undercity, as with many aspects of Diablo III, the primary goal is to acquire highly desirable new loot that will significantly enhance your character’s overall power. Reaching the ultimate floor of the dungeon on time allows you to claim a treasure-filled chest as your reward, secured only after defeating the formidable boss. However, you can further enhance this loot by filling up your meter. To reap any reward upgrades, you’ll need a minimum Attunement level of 1.
To prolong your Attunement, which allows you to stack up to four instances, you must activate it while dashing across the floor. Monsters spawned by these Beacons will swarm in hordes, their movements and actions directly tied to the beacon’s presence. If all enemies linked to the Beacon are eliminated, it will release a substantial amount of Attunement, gradually boosting your meter’s capacity for steady enhancement. Since we possess a surplus of Attunement Beacons, specifically Extra and Grand Beacons, you can easily surpass the Attunement meter’s maximum capacity without having to collect every single one. This means you can strategically skip certain beacons along the way while still reaping excellent rewards.
While designing an Attunement strategy, it’s crucial to acknowledge that this mechanic is intentionally crafted as an enticing test of self-control, where the oscillating dynamics of the Kurast Undercity exercise purposefully strive to temper one’s instinctual desire for immediate gratification. When operating under a tight deadline, it’s often crucial to pause and prioritize Attunement, as the benefits can far outweigh any minor loss in loot – effectively yielding a more substantial reward. As you focus on non-attachment, you’ll reap the benefits of a successful foray into the Kurast Undercity, where pleasant surprises await those who resist the urge to grasp at every opportunity.
