The Lost Halls is an endgame dungeon designed by Toastrz and Kiddforce. The original design document was made by Toastrz but the final version contained some noticeable differences and was “grander in scope.” The Records of the Lost Halls are a series of official lore entries that give backstory into the dungeon and hint at dungeon mechanics. The dungeon was released on August 1, 2017, coinciding with Month of the Mad God.

In addition to the main dungeon, there are 2 secret areas, each with their own boss. The bosses here are the only sources of the new T13 Weapons and T14 Armor, as well as a number of powerful Untiered items.

The portal has a chance of dropping from the Lost Sentry event boss, which spawns once per realm.

The current dungeon is more commonly known as “Lost Halls 2.0.” The “original” version of the dungeon (before Patch X.26.0.0) can be found here. The dungeon rework was due to several complaints that the main dungeon was too boring and tedious to clear, and often required large groups (30+ players) to complete in a timely manner. The update changed most enemy and boss behaviors, increased room variety, redid most of the artwork, buffed several Lost Halls UTs, and added HP scaling to all enemies to make the dungeon viable for most group sizes.

Main Area

The Lost Halls is composed of a large “grid” of 17x17 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.

Hazards

• Tiles of Water, Ice, or Pure Evil
• Un-walkable tiles scattered in the room
• Destructible Walls
• Invincible Marble Colossus Pillars that fire at players
• Invincible Marble Eyes that inflict AoE negative status effects corresponding to their color
• Arrow shooters in the walls that fire 150-damage arrows
• Bomb traps in the floor that constantly launch 150-damage AoE explosives. They come in two different types: one that fires at players and one that fires at itself.

Bonuses

• Friendly (lighter-colored) Marble Pillars that inflict all nearby enemies with status effects
• Friendly (lighter-colored) Marble Eyes that give all nearby players positive status effects

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.

Starting Room

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 kill them, opening up the corresponding path in the wall.

Pot Rooms

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.

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.

Pre-Boss Room

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.

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.

Enemies

Note: Most the enemies here give abnormally high amounts of XP, especially the leaders of each group, which give a whopping 4000 EXP. This makes it attractive for those wishing to gain a lot of EXP, as clearing everything before the boss can easily get players over 40 fame.
