Lost Ark – What Is Infinite Chaos Dungeon and Purification Fragments

What Is Infinite Chaos Dungeon?

Every day, you’re given 100 Resonance Energy which you spend 50 of at the Chaos Dungeon instance to receive loot such as equipment, accessories, etc.

Typically, after two runs, most people are done with Chaos Dungeon for the day.

However, a mechanic exists which allows you to continue doing Chaos Dungeon even after expending all of your Resonance Energy. This is commonly referred to as Infinite Chaos Dungeon.

When entering Chaos Dungeon with no Resonance Energy, enemies will drop two types of items. The main one that we are looking at is called Purification Fragments.

What Are Purification Fragments?

Pictured left is the Purification Fragment, pictured right is the orb used to exchange for random accessories from the merchant. Other loot you can get from Infinite Chaos Dungeon instance runs include occasional accessories and card EXP if completing the entire instance.

Purification Fragments are exchanged at the NPC right outside the Chaos Dungeon entrance.

The NPC in this picture is in the bottom right of the frame.

The Purification Fragment NPC will exchange goods used to improve your gear. Stock on most items is reset on the weekly reset and is account-wide.

There is a tab for Tier 1, Tier 2, and Tier 3. In the case of Tier 1 and Tier 2 merchant stock, there is a set price for each item you can purchase with the fragments. For Tier 3, the stock of materials increases with each purchase, gradually getting more and more expensive. It then resets at the start of the week back to its original price.

It’s a decent source of additional materials but more important than anything else is the fact that there is a one-time stock of engraving selection pouches you can pick up from turning in these fragments. This is one way that you can get an engraving of your choice guaranteed right after reaching level 50.
