Collect Lost Pages in the Library

In this zone event, Lost Pages are scattered all around the Library of Zoltun Kulle and you need to collect 5 to turn the Pages into Portal Tomes.

Note that Lost Pages can be seen and picked up by any player in the zone, so it's best to collect Pages as quickly as possible and outside of peak server hours.

Open Portals to Kulle's Hidden Chambers

Once you have collected 5 Lost Pages, you can use them as Portal Tomes via the Kulle's Hidden Chambers event tab in your Quest Log.

Using a Portal Tome can spawn a portal to one of Kulle's Hidden Chambers, which will challenge you with a horde of monsters and reward you with Enchanted Dust upon completion.

Note that you can save up to 5 Portal Tomes, so you do not have to immediately use all of them up each day.

Use Portal Tomes to Spawn World Bosses

Portal Tomes also has a small chance of spawning one of two world bosses (either Fleshcraft Hydra or Sandstone Golem), which requires many players to defeat and can drop valuable items such as Legendary gear and Horadric Vessels.

When a world boss is spawned, the entire zone is notified of its arrival and can Auto Navigate towards the spawn point of the boss.

Use Portal Tomes to Complete the Trial of Kulle

Entering and completing Kulle's Trial Chamber, one of the five random Hidden Chambers, will allow you to also complete the Trial of Kulle Achievement for the Library of Zoltun Kulle.

List of Hidden Chambers

Collecting five Lost Pages and using the Portal Tome will randomly activate one of the following five scenarios.

	Kulle's Hidden Chambers
1	Sandstone Golem
2	Fleshcraft Hydra
3	Kulle's Trial Chamber
4	Kill as Many Monsters as Possible Before the Timer Runs Out
5	Break all the Jars in the Hidden Chamber to Obtain Their Contents

Sandstone Golem

The Sandstone Golem world boss spawns in the Master's Sanctum at the northernmost part of the Hidden Alcove when summoned using a Portal Tome.

This fight is not as difficult as the Fleshcraft Hydra as the Golem has relatively simple attacks and mostly stands still.

When defeated, the Sandstone Golem drops 6 Enchanted Dust and the Guilt of the Nameless Horadric Vessel.

Fleshcraft Hydra

The Fleshcraft Hydra world boss spawns in its lair at the northernmost part of the Writhing Ingress when summoned using a Portal Tome.

This fight can be particularly tough as the Hydra uses many area-of-effect attacks and often moves from one location to another, so gear up accordingly when planning to fight this boss.

When defeated, the Fleshcraft Hydra drops 6 Enchanted Dust and the Zoltun Kulle's Ingenuity Horadric Vessel.

Kulle's Trial Chamber

To complete The Trial of Kulle, an Achievement for the Library of Zoltun Kulle Zone, you must enter and finish the Hidden Chamber of the same name. You'll know you've encountered the correct chamber as the Echo of Kulle will be standing in the center of the room.

Defeat the waves of monsters that he summons to receive a chest with 6 Enchanted Dust and other rewards, as well as the Hilts for completing the Achievement.

Kill as Many Monsters as Possible Before the Timer Runs Out

You have 1:15 to defeat four waves of monsters. You'll be rewarded with four chests containing 8 Enchanted Dust and other rewards upon successfully completing this chamber.

Break all the Jars in the Hidden Chamber to Obatain Their Contents

Examine the Ancient Tome and an Ancient Voice informs you: Hidden treasure awaits for those with cunning. This chamber is empty save for the two skeletal mages standing listlessly in the center.

The objective of this room is to break the jars lining the chamber. You can earn 6 Enchanted Dust as well as some gold from breaking the jars.
