The Lost Halls is an endgame dungeon and the second-most challenging dungeon in the game. In addition to the main dungeon, there are 2 sub-areas, each with their own boss. The dungeon is a source of numerous stat potions, top-tier gear, a large number of powerful Untiered items, the Lost Golem ST Set, and the only source of the Helmet Rune.
The portal is a guaranteed drop from the Lost Sentry event boss, which spawns up to once per realm.
The Lost Halls Key is available in the Nexus for 200 .
See the Lost Halls Guide for a walkthrough on the dungeon.
|The Realm Eye says:|
Oryx’s takeover of the realm resulted in many different efforts to reclaim the land. While fighters such as yourself attacked directly, researchers explored more scientific solutions.
To safely conduct research inside the realm, an enormous network of experimentation rooms were built deep underground, spanning almost the entire realm.
Highly unethical tests took place in the now abandoned halls. Documentation in this library is limited, but I believe written texts with greater detail exist somewhere in this world.
The Lost Halls is composed of a large “grid” of 8x8, 8x9, 9x8, or 9x9 rooms with hallways connecting them. Enemies are found in these rooms, with each room containing one Group Leader commanding their respective group. The rooms tend to look similar, but can have randomly-generated gimmicks found in them. These gimmicks range from beneficial to dangerous, such as arrow/bomb traps, ice tiles, Pure Evil, Marble Eyes that provide AoE status effects, etc.
The dungeon is fairly big and the boss doesn’t have a Quest marker until found, making it very hard to navigate. To add an element of dread and suspense, an invincible, lethal enemy called the Spectral Sentry aimlessly roams the halls, attacking anyone that approaches with unstoppable force.
Enemies in the main dungeon are lumped into 4 categories: Lost Crusaders, Oryx Infantry, Grotto Beasts, and Lost Golems. Enemies will always be found in these groups, which are detailed below.
There are several notable rooms that are different from the others.
The Starting Room is a square room containing 1-4 Pillars inside, facing a wall. In order to enter the main dungeon, players will have to stand close to these Pillars to drop their invulnerability and kill them, opening up the corresponding path in the wall. Each pillar has 15,000 base HP, 35 DEF, and HP Scaling.
Exactly five of the seven dead ends have a multitude of Treasure Pots that can drop bonus loot such as Tinctures, Effusions, and Stat Pots. A number of the Pots will spawn Evil Spirits, but one of them will have a passive pink flame that will teleport itself to the Treasure Room boss. These flames are essential for accessing the secret area of the dungeon. Additionally, after a Flame is found, it becomes visible on the minimap, thereby revealing the location of the Treasure Room.
One of the dead ends will be a Treasure Room. The Treasure Room is a large room identical to the ones normally found. It is completely empty except for the Treasure Room Boss, the Agonized Titan, in the middle and a locked portal to the Cultist Hideout.
The last dead end, just before the boss room, is a relatively empty room, containing only the Marble Defender. Once found, it will become each player’s Quest, making it easier to find for players that have split up. After being defeated, the wall behind it opens to the Boss Room.
The Boss Room is a large square room, much larger than the normal rooms found in the dungeon. The Boss resides in the middle of the room. This room has one entrance which is blocked off by the Marble Defender, and the entrance seals off after the boss is activated.

Note that once you enter the Cultist Hideout, you can not go back to the Lost Halls.
The Cultist Hideout consists of a series of hallways made of brown bricks. The enemies are found in small groups throughout the dungeon. Malus and his cultists are found in a large square room with a pentagram in the middle.

The Void consists of a large circular platform of purple tiles, in an expanse of Pure Evil. As time goes by, the platform will slowly get smaller as it is swallowed up by Pure Evil, and as the boss takes damage he will split the platform in two, and later in four.
A very high degree of teamwork and coordination is required to finish this dungeon. The layout is very confusing and the enemies require a large amount of combined DPS to take down. Stick together: spiltting up only makes it harder to take down the clusters of enemies.
Note, however, that there are no dead ends, meaning that any path leads to either the Boss, the Agonized Titan, or a Pot Room.
For Rogues who want to rush, beware of Grotto Blobs, Grotto Rats, Grotto Bats and Champions of Oryx, as they fire regardless of player presence. Especially beware the Grotto Rats, Grotto Blobs or Champions of Oryx - the first one because of their Quieting shots, the latter two because running into them will all but guarantee your death. This isn’t just for Rogue - it applies to all rushers.
It is important to remember that every enemy group has a different role to play in the dungeon. Keep their roles in mind when you engage them in combat. In addition, different groups in the Halls usually have common immunities and vulnerabilities.
Always stay on guard in case the Spectral Sentry appears. In case it does, make sure you have a clear path to escape the Sentry. But be careful after 15 seconds it will teleport to the nearest player or decoy. It will do this twice before it despawns.
This dungeon has 2 different true objectives:
Gathering all pink flames on the map to kill the Agonized Titan to reach the Cultist Hideout to obtain the Vial of Pure Darkness.
Killing the Marble Colossus and then using the Vial of Pure Darkness to reach the Void and defeat the Void Entity.
Interestingly, in the Cultist Hideout, the correct path to choose at a branch is always the one with no beam hanging over it.
