The Lord’s Labyrinth was introduced on March 4, 2016, as part of the Ascendancy expansion to Path of Exile which added new content and features such as Ascendancy Classes & Labyrinth Enchantments. Unlike most areas in the game, the Labyrinth's layout is randomised every 24 hours and will otherwise remain the exact same for all players during that period of time. The Labyrinth is a very iconic part of the game due to its unconventional gameplay and Hardcore-like nature; the penalty for dying in the Labyrinth is having to start it over from the beginning!

There are four different versions of Izaro's Labyrinth and they must all be completed in order to gain your eight Ascendancy points for your Class. The first three versions can be unlocked by completing the Trials of Ascendancy that are located throughout the Campaign. The fourth version, known as the Eternal Labyrinth, can be entered at any time after completing the campaign by paying the entry cost of 1x Offering to the Goddess. 

Throughout the first three acts, there are six Trials that need to be completed in order to gain access to the Aspirants' Plaza. Once these trials have been completed, you can access the Aspirants' Plaza via the large plaque located within the Act 3 Sarn Encampment. Completing the Labyrinth for the first time will grant you the ability to Ascend!

Each class has three ‘Ascendancies’. Ascendancies are specialised versions of your base class. Each time you complete a labyrinth version for the first time on a character, you will be granted 2x Ascendancy points which can be used to further improve and specialise your character.

Once you have opened the passage to the Aspirants' Plaza, it can be accessed again in future directly via a waypoint within the plaza itself. The campaign contains six more Trials; prerequisites for the Cruel and Merciless Labyrinths which will grant 2x additional Ascendancy points each. Information on all twelve trials can be found below:

Many traps deal a percentage of your life as Physical, Fire or Chaos damage over time. Damage over time is NOT reduced or evaded by defensive types like Armour/Evasion/Dodge/Spell Suppression. To mitigate damage over time, you will want some of the following tools:

Spike Traps deal 1/4 of your Life and Energy Shield as Bleed Damage and lock your character in place by shooting out of the ground in a square-shaped area either at a preset frequency or when their pressure plate is stepped on. You can check whether a Spike Trap is frequency or pressure based by waiting to see if the spikes shoot out on their own.

A Spike Trap blocks movement while it is open, and it is impossible to pass through it, so walk step by step like in the video showcase!

Sawblades deal Physical damage over time when you get in contact with them. They deal enough damage to kill you with one full second of contact if you don't have adequate mitigation.

Sawblades move back and forth along a straight line independently of whatever your character is doing. As you may notice in the video, sometimes you can use a lever to prevent them from moving at all.

Upon full contact, Spinning Blades cause a large enough amount of Physical damage over time to kill you within one full second of contact! They follow a predetermined route on the ground back and forth. Activating levers on the ground can shift these traps between their set tracks. In comparison to Sawblades, Spinning Blades have more complex pathing.

Use Flame Dash and walk alongside a wall or the edge to avoid getting hit by two or more of them simultaneously! Most importantly, if you can't avoid them entirely, don't run along their path and instead rush right through them as they approach you to minimise the damage you take.

When standing over activated Furnace Traps you receive Burning damage over time which can be fatal even if the player has 75% Fire resistance. Furnace Traps function according to a timer which causes them to deal damage only for a period of time. The best way to deal with these traps is to wait until they cool down and are no longer actively dealing damage to move over them.

Blade Sentries are wide, circular Traps that deal Physical damage over time that follow a set route. Their damage increases as you get closer to their centre.

Use Flame Dash or any other Movement Skill and walk alongside a wall or the centre between them to avoid getting hit by them while you walk. Similar to the other mobile Trap types described above, it's best to rush straight through them in the opposite direction if you can't avoid them.

Like Spike Traps, Dart Traps are either frequency or pressure based. They deal Physical damage and inflict Poisons which deal Chaos damage over time. They also apply Hinder (slow) when they hit you.

Cleaver Traps deal a high amount of Physical damage on hit and apply Bleeds. Cleaver Traps are frequency based and deal damage once every few seconds to a small area. They only appear in narrow walkways. These Traps only appear in the Eternal Trials and (Uber) Eternal Labyrinth.

An area can be affected by a Sentinel Trap in many ways. By dealing damage to the sentinels, Traps can be temporarily deactivated. These traps only begin appearing in the Eternal Labyrinth. These Traps only start appearing in the Eternal Trials and (Uber) Eternal Labyrinth.

When you die in the Labyrinth, your run comes to an end, It is therefore mandatory to survive the entire run in order to achieve completion. If you leave the area for any reason, your current attempt is ended and you will have to start from the beginning upon your return. While navigating the Labyrinth, you will fight "Izaro" three times in a boss arena, removing one third of his health each time until the final fight which culminates in his death.

On your way through the Labyrinth, you may find secret passages to take a shortcut or various buffs to speed up your run or make the fight against Izaro a bit easier.

Secret Passages are shortcuts to a later room without having to run through the complete layout. If there is a Statue, Coffin or Well that becomes highlighted by hovering over them, this indicates that a secret passage will open upon being clicked.

Each day, the Labyrinth includes a handful of Mysterious Darkshrines which are hidden shrines that impart beneficial effects to you for the remainder of the run, however they are often hard to find and can in many cases not be worth the time it takes to obtain these buffs. In some cases, these Mysterious Darkshrines grant an extra treasure key or an additional use of the Divine Font.

Argus is Izaro's loyal little dog companion and awaits you within the Merciless and Eternal Labyrinths. He drops a Treasure Key upon being defeated. Argus spawns in a random room behind a closed door depending on the Labyrinth's daily layout, however if you do find him, it is best to move on and avoid him.

When completing the Normal Labyrinth for the first time, you get the choice of an Ascendancy class. The Altar of Ascendancy is located in the upper left corner of the final room and make your decision. You receive two additional Ascendancy points for the first time you complete the Cruel, Merciless, and Eternal Labyrinth.

You earn one Treasure Key is earned by killing Izaro final encounter and two more by keeping some of this extra boss mechanics active without destroying them. Other Treasure Keys can be earned by completing certain challenges (Dark Shrines, Chests and Argus) through the Labyrinth. You can use these keys to open Izaro's treasure chests in the reward room. Related items like Treasure Keys, Silver Keys and Trinkets cannot be carried over from the Labyrinth, they are deleted from your inventory upon exiting.

Enchantments are the granted by the Divine Font and a very profitable farming target in Trade Leagues nowadays. You can use any items in your stash or inventory as long as they are Gloves, Boots or Helmets. The only exception is Belts in the Dedication to the Goddess Labyrinth.

Izaro is the creator and protector of the Labyrinth. His main types of damage are Physical and Fire. Three different combinations of weapons are available to him: a Two-Handed Mace, Dual Swords, and a Sword and Shield.
