The Trials of Ascendancy

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’. These are specialized versions of your base class. Each time you complete a labyrinth difficulty for the first time on a character, you are granted 2x Ascendancy points which can be used to further improve and specialize 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.

Act 1, The Lower Prison - Normal Labyrinth

In Act 1 when you enter the Lower Prison (1) you encounter the first Trial of Piercing Truth, which includes Spike Traps.

Act 2, The Chamber of Sins Level 2 & The Crypt Level 1 - Normal Labyrinth

The next two Trials of Ascendancy are located in Act 2. 

The Trial of Crippling Grief is found in The Chamber of Sins Level 2 (2), which contains Sawblade Traps.

Act 10, The Ossuary - Merciless Labyrinth

The Trial of Stinging Doubt (3) is located in Act 10 The Ossuary. It is full of poisonous Dart Traps.

Traps

• Fixed value #% Additional Physical Damage Reduction (not Armour) or Endurance Charges to reduce the amount of incoming Physical damage over time.
  • While rare, #% less Physical damage over time on your items is very effective.
• #% Life Regeneration or flat # Life Regeneration is a good source of permanent Life sustain.
  • The Vitality Aura is a great way to get Life Regeneration during the Campaign.
  • Enduring Cry, or a Summon Stone Golem are good additional sources for #Life Regeneration on most builds.
• Taking two or three extra Life Flasks is by far the easiest way to have a good time. For example, this Saturated Divine Life Flask of Perenniality (high amount of Life + extra recovery) is "best in slot" in order to sustain your Life.
• Movement Skills like Flame Dash that teleports your character to a location allowing you to skip through certain traps without taking damage.
• Fire and Chaos Resistance help to mitigate non-Physical trap damage.

Spikes

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!

Counter Spike Traps by watching the pattern, and moving when they're inactive.

Sawblades

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.

Counter Sawblades by avoiding them, or running through them so you spend a minimal amount of time in contact with the blade. NEVER run in the same direction as the blade!

Spinning Blades

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.

Counter Spinning Blades using 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 minimize the damage you take.

Furnace

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.

Counter these traps by waiting until they cool down and are no longer actively dealing damage, then move over them. If you must run over an active Furnace Trap make sure to have Life Flask charges to heal through the Burning damage.

Bladed Sentries

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.

Counter Blade Sentries using 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.

Dart Traps

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.

Counter Dart Traps by watching the pattern, and moving when they're inactive. If you trigger a Pressure Plate move quickly to avoid taking consecutive hits. Movement skills like Flame Dash are important for countering the slowing effect applied by the trap.

Cleaver

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 the Eternal Labyrinth.

Counter Cleaver Traps by waiting for the blade to slam down, then moving through as it begins to rise and reset.

Sentinels

An area can be affected by a Sentinel Trap in many ways. These Traps only start appearing in the Eternal Trials and the Eternal Labyrinth.

Counter Sentinel Traps by dealing damage to them. This temporarily deactivates the Traps and you can pass by safely.

• Endless Drought - Removes Flask Charges.
• Endless Hazard - Covers the area with several green circles on the ground with the effect: % of Life/Energy Shield to take as damage on using a movement skill taken Physical Damage whenever you use a Movement Skill.
• Endless Pain - Has an aura that applies 50% increased damage taken.
• Endless Sting - Causes Bleeding.
• Unending Fire - Casts Fire Nova.
• Unending Frost - Casts Ice Nova.
• Unending Storm - Casts Shock Nova.
• Unending Lethargy - Has a Temporal Chains aura.

The Lord's Labyrinth

• Treasure chests which can be opened with Treasure Keys collected during the run.
• The Altar of Ascendancy which rewards you with Ascendancy points if it is your first time clearing that version of the Labyrinth on that character.
  • Alternatively allows you to respecialize your character into a different Ascendancy if you have refunded all your Ascendancy Points first.
• The Divine Font, a single use crafting bench that is used to Enchant your gear.

Layout & Mechanics

Secret Passages and Rooms

Mysterious Darkshrine

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.

Divine Font

Izaro the Emperor

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. In order to obtain enough defense for the fight take a look at our Defenses Guide and follow these tips:

• Since Izaro uses Physical Attacks, Armor and Evasion are great defensive layers. Determination, Grace or Defiance Banner are the best auras for dealing with this.
• #% Physical Damage Reduction or Endurance Charges are also effective ways to reduce the amount of incoming Physical Attack damage
• If you don't use any Darkshrines, there are Traps in the final Izaro encounter, so having sources of #%leech, #%Life Regeneration, or #Life Regeneration in addition to high tier Life Flasks is very important.
• Enduring Cry & Vitality are good sources of #Life Regeneration that can help keep you alive when you don't have any Flask charges left.

Skill Breakdown

Izaro's Mechanics

In each Labyrinth you encounter Izaro a total of three times in the Aspirant's Trial, each ending at 66%, 33% and finally 0% HP. Before the fight, you have access to your stash to store items and can see which buffs are currently affecting Izaro. There are mechanics that buff Izaro's damage, defenses, or speed; and they can be seen in the right (second Izaro encounter) and left (third Izaro encounter) corner in the Aspirant’s Trial.

Similar to how the Labyrinth's layout is randomised each day, so are the extra mechanics affecting him. Each additional mechanic that affects Izaro can be removed for the remainder of that run by defeating a corresponding enemy or by interacting with the mechanic in some way that deactivates it during the Izaro fight. Doing so causes Izaro to drop one less key for each removed mechanic.

Conduit of Flames/Frost/Storms

In each corner of the room, there is a statue representing each element. A statue's active state increases Izaro's damage and resistance to the related element. You can deactivate the statues for a short period of time by clicking them.

Charge Disruptors

When this mechanic is active, Izaro will gain charges throughout the fight. Each charge grants him bonuses for speed, defense, or damage up to a maximum of 10 charges. There are three Charge Disruptors that can be activated to remove charges, and each Disrupter can only be used once.

Elemental Essences

The Elemental Essences take the form of elemental Golems:

• Summon Ice Golem
• Summon Flame Golem
• Summon Lightning Golem

The Golems enter the fight one after another and slowly walk towards Izaro. When they touch him, they are absorbed and grant related buffs. They also grant additional damage, resistance, and the chance to apply a Status Ailment that corresponds to their element - Ignite, Shock and Chill/Freeze.

Gargoyles

Izaro summons three Gargoyles to assist him and as they stay inactive, they have extremely high amounts of damage reduction, making killing them very difficult. The Goddess of Justice channels a beam at a Gargoyle which activates it and causes the loss of its damage reduction - this is the time to attack it in order to destroy the Gargoyle!

• Granite-infused Gargoyle grants damage reduction.
• Steel-imbued Gargoyle grants extra Physical damage.
• Basalt-infused Gargoyle grants increased damage dealt.
• Quicksilver-infused Gargoyle grants increased movement speed and attack speed.

Idols

Three Idols spawn in each corner, one for each element (Fire, Cold and Lightning). The Idols cannot die and slowly regenerate Life over time. Idols use life as a resource, unleash a series of elemental damage explosions when their life reaches full.

If an Idol’s life reaches full and it unleashes this spell at least once, it will return in subsequent fights within the same Labyrinth run. If all three Idols cast their spell at least once, Izaro will drop an additional key.

Lieutenants

Three skeletal Lieutenants successively spawn in each corner, one at a time. Each Lieutenant is related to one of the three elements and has different skills and passives:

• Fire Lieutenant of the Mace
• Cold Lieutenant of Rage
• Lightning Lieutenant of the Bow

If a Lieutenant is not slain, it will return in subsequent fights within the same Labyrinth run. All three skeletal Lieutenants must be alive when Izaro is slain in order for Izaro to drop an additional key.

Summoning Portals

Three Portals successively spawn in each corner. Each portal steadily summons Skeletal Mages until destroyed. If a portal is not destroyed it will return in subsequent fights within the same Labyrinth run.

All three Portals must be active when Izaro is slain in order for Izaro to drop an additional key.

Fonts

Three Fonts successively spawn in each corner and will begin casting curses at the player. These fonts can be destroyed, however any portals that are not destroyed will return in subsequent fights within the same Labyrinth run. All three Fonts must be active when Izaro is slain in order for Izaro to drop an additional key.

Upon killing a font, it will cast an empowered version of its corresponding curse on you that lasts 10 seconds:

• Font of Fragility casts Vulnerability. 
• Font of Lethargy casts Temporal Chains.
• Font of Elements casts Elemental Weakness.

Summary

• The Trials of Ascendancy must be completed before you are allowed to enter the Lord's Labyrinth.
• You can pick your Ascendancy Class after completing the first Labyrinth. The first time you complete each Labyrinth on a character, you receive 2 Ascendancy Points, up to a total of 8.
• When you enter the Labyrinth , you must navigate through it without dying, otherwise you have to start over again.
• Life sustain and Physical damage reduction are the most important stats for improving your survivability within the Labyrinth - Take extra Life Flasks and Life Recovery for better survivability.
• Running endgame Labyrinths for Enchantments is a very lucrative farming strategy in Trade Leagues.
