With Diablo 4 Season 3’s exciting new features, players have the opportunity to delve into fresh mechanics, rebalanced gameplay, and thrilling endgame pursuits. A highlight of each season is the new Season Questline, offering a deep dive into the game’s lore and a host of challenging enemies.

In this season’s “Season of Construct,” one side quest that stands out for its challenge is the Kulle’s Heart quest. This guide will walk you through the steps to conquer this quest in Diablo 4 Season 3.
Steps to Unlock and Complete Kulle’s Heart Quest
Unlocking the Quest
To start the Kulle’s Heart Quest, first complete “Ennead,” the third mission in the Season 3 questline. The quest revolves around locating five of Zoltun Kulle’s journals.
Locating the Journals
The quest begins in the Gatehall, where you team up with Ayuzhan. Two of Kulle’s journals are located here:
- The first journal is retrievable upon rescuing Ayuzhan.
- The second is on a table in the northern part of the hall. Both journals are marked on the map once you activate the Kulle’s Heart Quest.
For the final three journals, you need to explore Vault Dungeons, accessed through open-world entrances scattered across different zones, the Gatehall main hub, or by using crafted Vault Sigils for higher-level dungeons.
Efficient Journal Collection Strategies
It’s important to note that the Wardwoven chests at the end of these dungeons only sometimes contain the quest items. To increase your chances, focus on opening as many Handwoven Chests as possible.
Completing the Quest
After collecting all five journals, you won’t find any more duplicates. While there are no additional tasks post-collection, you’ll receive a reward of gold and experience.
This guide should help you efficiently complete the Kulle’s Heart quest in Diablo 4, paving the way for more adventures and resources in the game.
