The Truth That Lies Within is a repeatable quest in Diablo 4 Season 9 that’s part of the Sins of the Horadrim storyline. You will run into it multiple times as you progress through the season. The main goal is to collect Horadric Knowledge, which helps you unlock the next steps in the questline. This guide will show you how to complete it, the best ways to farm knowledge points quickly, and what bugs you should be aware of while doing the quest.
The Truth That Lies Within
During the Sins of the Horadrim questline, you will come across The Truths That Lie Within quest more than once. After you complete certain parts of the story, this quest asks you to collect Horadric Knowledge so you can unlock the next step in the questline.
You will need to enter a Nightmare Dungeon and defeat enemies to collect Horadric Phials. Look out for Horadric Strongrooms inside the dungeon; they give you a bunch of reputation items at once.
If you can’t clear them all, you can still make good progress without them. After you have collected enough Horadric Knowledge, The Truths That Lie Within quest will be completed. You can farm it anytime. Remember to bring along any Horadric Spells you already have.
The best way to earn points fast is by clearing Strongrooms, so jump into those Nightmare Dungeons and start farming. And every Nightmare Dungeon for this quest guarantees a Strongroom, so you don’t have to search for one.
Bugs in The Truth That Lies Within
Right now, you need to gather 26,000 Horadric Knowledge to move forward in the season questline. But you don’t actually need to hit 26,000 to unlock the next quest. You can also get Horadric Knowledge by doing other things, like killing bosses. The system has bugs. When you are around 15,000 Knowledge, you can spot the seasonal quest on your map without doing anything special.
