The Lord's Labyrinth

"Having proved your mettle in the Trials of Ascendancy, you earn the right to enter Izaro's Labyrinth. Centuries have passed, but its traps are as dangerous as the day its doors were first opened."

— Description on the official Path of Exile website

The Labyrinth is a randomly generated dungeon filled with traps, puzzles and monsters. After having completed the Trials of Ascendancy in the current difficulty level, the player can enter the Labyrinth through the Statue of the Goddess in The Sarn Encampment.

The Statue of the Goddess closed entrance

The Statue of the Goddess opened entrance

The traps from the Trials of Ascendancy (and one trap that was not showcased there) are combined in gauntlets throughout the Labyrinth. Its random level generation extends beyond single areas and affects the entire Labyrinth at once. Every day, the Labyrinth has a completely new layout. There are four different Labyrinths: one for each difficulty and one additional endgame dungeon. The layout is the same for every league, but differs in each difficulty. When the Labyrinth is generated, keys to locked doors are placed behind traps, hidden passages are created that connect areas and secret rooms are placed. Three times, the player encounters Izaro, and the fight will evolve depending on the player's actions in previous encounters. The first two fights end when Izaro's hitpoints are reduced to 2/3 and 1/3 respectively, the last one ends when Izaro is defeated. The last fight takes place in an arena containing many traps from the Labyrinth.

The Labyrinth takes an experienced player around 30 minutes to complete. Players can not portal out to town; if they leave the dungeon, they will have to start all over again. The Labyrinth can be attempted as many times as desired.

Completing the Labyrinth on normal difficulty grants the player the ability to choose an Ascendancy class on top of receiving two points to spend on the Ascendancy skill tree. On completing the cruel, merciless and endgame Labyrinth the player again receives two points each. In addition, every time the player completes the Labyrinth, he may imbue one piece of equipment with an enchantment.

There are daily leaderboards where players can compete to solve the Labyrinth the quickest.

Traps

There are several different traps in the labyrinth. They can be deadly, usually dealing a percentage of the player's life or energy shield pool as physical damage. The most common ones are introduced to the player in the Trials of Ascendancy.

Spike traps

Spike traps

Spike traps shoot out of the ground in a square area according to a timer, taking 1/4 of the player's effective hitpoints (including life pool and energy shield pool) and locking him in place. This kind of trap isn't very dangerous, because it cannot kill fast and the lost hitpoints can be recovered using potions.

Spike traps are showcased in the Trial of Piercing Truth, located in the Lower Prison.

Sawblades

Sawblades

Sawblades run along a set path, taking player's energy shield and health quickly when cut by them, enough to kill in roughly one second. The damage does not depend on difficulty, but the layout is harder on higher difficulties. Sawblades can often be switched on and off with nearby levers.

Sawblade traps are showcased in the Trial of Crippling Grief, located in the Chamber of Sins Level 2.

Spinning blades

Spinning blades

Spinning blades are large traps which follow a set path along the ground and can go around corners, taking player's energy shield and health quickly when cut by them, enough to kill in roughly one second. The damage does not depend on difficulty, but the layout is harder on higher difficulties. They can sometimes be diverted from one track to another by using activating levers.

Spinning blades are showcased in the Trial of Swirling Fear, located in the Crypt Level 1.

Furnace traps

Furnace trap

Furnace traps periodically fill the floor with lava, taking the player's energy shield and health quickly when hit by them, enough to kill in roughly five seconds. The damage does not depend on difficulty, but the layout is harder on higher difficulties. The health loss can be countered with potions and partially avoided with . It does not affect fire-related monsters.

Furnace traps are showcased in the Trial of Burning Rage, located in the Crematorium.

Blade sentries

Blade sentry

Blade sentries are very wide traps that move along set paths (either on the ground or flying above obstacles) taking player's energy shield and health quickly when cut by them, enough to kill in roughly one second. Their rotating blades do more damage the closer you are to them. The damage does not depend on difficulty, but the layout is harder on higher difficulties.

Furnace traps are showcased in the Trial of Lingering Pain, located in the Catacombs.

Dart traps

Dart trap

Dart traps are pillars that fire projectiles repeatedly in multiple directions, slowing down the player and making him an easy prey for other traps or monsters. They do not deal damage and no status effect is displayed when the player is affected. Dart traps are often linked to hidden pressure plates.

Dart traps are showcased in the Trial of Stinging Doubt, located in the Hedge Maze.

Sentinel traps

Sentinel trap

Sentinel traps apply one of many effects to an area. For exxample, they can have an ice nova effect that deals could damage in an area around them. Sentinel traps can be temporarily deactivated by dealing damage to them. They only appear in the endgame Labyrinth.

Sentinel traps are showcased in the endgame trials, which can randomly be found in maps.

Other traps

Various other traps appear in the Labyrinth, such as vertically moving spinning blades (often guarding an entrance) and others.

Endgame Labyrinth

The fourth labyrinth is accessed differently, through end-game maps. Completing the trials in maps reward players with an Offering to the Goddess item, which needs to be used in the map device in order to enter the endgame Labyrinth.

The endgame trials and Labyrinth include a new trap type: Sentinel Traps. These traps apply one of many effects to an area and can be temporarily deactivated by dealing damage to them. Upon completing the endgame Labyrinth for the first time, players are rewarded with two additional Ascendancy points and a new tier of possible enchantments.

Leaderboards

Players are ranked based on how quickly they have completed the Labyrinth. To be eligible for the leaderboard, players must enter the Labyrinth alone. The Labyrinth must be completed before the daily changeover to the next labyrinth layout. There are leaderboards for all four labyrinths in each league, resulting in 16 different leaderboards.

• Players are timed from when they enter the portal in Sarn Encampment until they kill Izaro.
• To be eligible for the normal leaderboards, players must be level 40 or lower.
• To be eligible for the cruel leaderboards, players must be level 60 or lower.
• There are no level restrictions for the merciless leaderboards.

At midnight UTC, prizes will be deployed to the players who finished the Labyrinth the quickest that day. The prizes received depend on the difficulty level. For every leaderboard, the top player will be rewarded, so each reward will be distributed four times every day.
