Uncover the Secrets to Maximizing Time and Treasure in Kurast Undercity Diablo 4

Unlocking the Kurast Undercity in Diablo 4: A Step-by-Step Guide

In Diablo 4’s first expansion, Vessel of Hatred, you’ll have the opportunity to explore the Kurast Undercity, a time-attack-style dungeon that challenges you to blast through the city’s underground levels as quickly as possible. But before you can dive in, you need to know how to unlock the activity. In this guide, we’ll walk you through the process of unlocking the Kurast Undercity, upgrading your loot chest, and maximizing your time.

Unlocking the Kurast Undercity

To unlock the Kurast Undercity, you need to progress through the Vessel of Hatred campaign until you reach Kurast and complete some work for the council. This should happen around the time you face the first major boss. A council member will then teach you how to do the basic version of the Kurast Undercity.

Getting More Time in the Kurast Undercity

Ideally, you can stack up multiple Afflicted Monsters at once and deal area damage to kill them all at the same time, netting you a lot of time back for not much time spent.

Upgrading Your Loot Chest

The whole point of the Kurast Undercity, like most activities in Diablo 4, is to get powerful new loot and further improve your build. You’ll get a chest filled with loot by reaching the final floor of the dungeon in time and then killing the boss. But you can upgrade this loot by filling up your Attunement meter. You need to have at least Attunement level 1 to get any reward upgrades.

Increasing Your Attunement

To increase your Attunement, which you can stack up to four times, you need to activate Beacons and Grand Beacons while racing through the floors. These Beacons will spawn a horde of monsters that are all linked to the Beacon itself. If you can kill every enemy attached to the Beacon, it’ll spew out a bunch of Attunement, which will steadily increase your meter. In our experience, there are more Attunement Beacons and Grand Beacons than you’ll need to cap out your Attunement meter, so you can skip some as you go and still get decent rewards.

Tips for Running the Kurast Undercity

The only thing to be aware of with Attunement is that it’s designed to be a trap, meaning the push and pull of the Kurast Undercity activity is trying to test your greed. If you’re running low on time, stopping for more Attunement could cost you the entire run, meaning you get no loot rather than getting slightly less loot. Try not to be greedy, and you can get some great rewards while grinding the Kurast Undercity.
