I've been a Diablo streamer since 2013. You may have seen me playing my favorite class, Wizard! I'm known for my technical gameplay and guides that break down mechanics to make them easy to learn. I love testing new content, making discoveries and creating builds. Skillful gaming is my priority, so I'm always looking for the next challenge to push myself even further beyond. There are no timings too strict or APM requirements too high that can deter my training. Maxroll has always been about bringing you the absolute highest level information, so I'm thrilled to be on the team. 
Introduction
Zone Events are some of the most rewarding activities in Diablo Immortal. Kulle's Hidden Chamber is an event specific to the Library of Zoltun Kulle zone in Hell Difficulties. Show up at the event times to kill the Hydra and Sandstone Golem for a chance to get Legendary equipment.
Portal Tomes are commonly referred to as "Books". The gathering of players opening books together is called a "Book Club". Book worms love hanging out in the library.
Check our Zone Events Guide for additional information.
Kulle's Hidden Chamber Mechanics
- Gather Lost Pages, which are shiny golden objects scattered around the floor of this zone.
- 5 Lost Pages combine into a Portal Tome. Most of the time using it opens a portal to a private area where you do a quest for rewards. Party members can see your portal, but they need to spend a book of their own to enter it. Unlike other Zone Events, these portals give different amounts of Enchanted Dust and equipment drops.
- There's a small chance that a Portal Tome spawns a World Boss. There are 2 World Bosses, Hydra and Sandstone Golem, that spawn in their own chambers. Everyone that hits the boss will receive rewards, even if they aren't in your party. A countdown of 3 minutes gives you time to reach the chamber and notify friends to join for rewards.
- Each portal event will only drop rewards 5 times per day.
Strategy
Run routes that pass by Lost Page spawn locations. They are global spawns so make sure you pick them up before someone else does. Don't forget to do any quests that popup for extra Enchanted Dust. Teleport to the waypoint of another route once you finish running one.
It becomes harder to find Lost Pages if the zone is crowded with other players, so try checking other difficulties for less players. Don't forget to hit up other scheduled Zone Events, since this event is always available.
Up to 5 Portal Tomes can be saved up. Gather your friends that also have tomes and open them at the same time to increase the chances of a World Boss spawn. Run any portals that you open solo. Do not enter another person's portal because it consumes one of your tomes and therefore erases another chance at a World Boss spawn.
Kulle's Hidden Chamber Rewards
Gathering Lost Pages while completing quests in the zone is the most efficient way to gain Enchanted Dust outside of scheduled Zone Events, making the Library of Zoltun Kulle the BEST location for long term farming. This popular farming spot can become crowded, reducing your farming efficiency.
