How To Unlock Trial Of Chaos In Path Of Exile 2 Early Access? - By Defeating Xyclucian
As you explore Path of Exile 2 Early Access, you’ll have the opportunity to gain access to some Ascendancy Classes with more powerful abilities to help you take on more difficult battles or missions, but please note that you’ll need to complete some Trials before you can get them.
The first one you’ll encounter is Trial of Sekhemas in Act 2, where you’ll first unlock some Ascendancy Classes, and to unlock all of them, you’ll need to complete Trial of Chaos in Act 3. But this Trial isn’t that easy to unlock, you’ll need to complete a boss encounter with Xyclucian, The Chimera.
This is the boss you’ll encounter while searching for Jiquani’s Machinarium in Chimeral Wetlands. Since this three-headed enemy uses a variety of elemental attacks that are difficult to dodge, you’ll need the specific methods and strategies for finding and defeating Xyclucian in this guide to ensure that your subsequent Trials exploration is not affected.
Xyclucian, The Chimera Location
You’ll find this boss in Deadly Nest on Chimeral Wetlands map in Act 3 of POE 2. In addition, since Xyclucian is the last challenge of Legacy of the Vaal main story quest, you won’t miss this encounter once you claim it.
How To Defeat Xyclucian?
Like most boss encounters in POE 2, only by knowing all of Xyclucian’s attacks in advance can you avoid them as effectively as possible and find opportunities to deal some lethal damage during the fight. Here are all of Xyclucian’s moves in this fight, as well as tips and strategies you can use.
Slam
This move is used in many boss encounters, but here Xyclucian doesn’t use his hands to do this, but instead slams his front legs, and the powerful shockwave is generated from this position.
Since Xyclucian will roar before slamming, you can use this time to move away from his front legs to avoid taking too much damage. The best place to cast damaging skills may be his back, because at this time, all his attention is on the front and he has no time to pay attention to the back area.
Ice Breath
As mentioned earlier, Xyclucian, The Chimera is a monster with three heads, and in Ice Breath you will see some ice spraying out of his right head, and it will cover some areas of the arena around where he is standing with this ice, which will cause continuous damage to you.
This attack has a large range of influence and the damage is also very deadly, so when you see his right head start to swing and prepare to spray some frost, please move away from where you are standing.
Not only that, but since this attack is homing, your character will need to be constantly on the move to avoid taking damage. You can try investing in some POE 2 Divine Orbs in gear that gives you a high buff to your movement speed or rolling dodge to increase their rarity and power.
Jump Slam
Here, the boss will jump into the air, then come down hard and deal massive damage where it lands. But be aware that it will not land in the same spot it took off from, so watch its path as you move to avoid damage.
Flamethrower
The right head of Xyclucian you just introduced will let you spit out some ice, while the middle head will spit out a wave of flames. Also note that the boss will swing his head back and forth during this attack, making the cone in front of him very dangerous.
When countering this move, in addition to ensuring your mobility, make sure your build is strong in fire resistance, as this elemental damage will be more powerful than the physical damage you have previously taken. While dodging, don’t forget to get behind the boss and do as much damage as possible.
Stone Pillar
When Xyclucian, The Chimera starts to go up, it means that it will fly to the top of a Stone Pillar in the arena and shoot some fireballs at you. In this case, the first thing you should do is definitely not to cause more damage to the boss itself, but to destroy the stone pillar it is standing on, because after the stone pillar collapses, Xyclucian will fall with it and will be very vulnerable for a few seconds, which is the best time to attack it.

Flying Flamethrower
In addition to Stone Pillar, Xyclucian will also perform Flying Flamethrower attack on you when it flies into the air: it will directly spray fire in a straight line towards the center of the arena, of course, this attack will also follow you.
So you can use the previous strategy and try to stay behind the boss, so that you can ensure that you are as little exposed to the fire with huge damage as possible.
Poison Lob
Xyclucian’s head can not only deal some damage to you but also his tail! You will see poison balls being fired from the boss’ tail in a cone-shaped pattern, causing poison damage in a small area when they land.
Due to the large number of poison balls fired and their high frequency, you will inevitably be hit by some of them, but make sure you don’t get hit by them continuously, because once the poison damage is stacked, the consequences will be unimaginable.
Lightning Breath
For Xyclucian’s left head, you can’t underestimate it either, because it will fire some lightning balls at you, which will explode after a while. The best way to avoid these lightning balls is to let them explode in the air as much as possible instead of on you, so pay attention to the trajectory of these small balls and avoid them strategically.
Flying Slam
Compared to the previous Slam and Jump Slam, the landing damage caused by Flying Slam here will be higher and because the boss will disappear in the air for a second, it is difficult to judge where it will appear, though where it disappears.
Note that Xyclucian is invincible whenever he jumps, flies, or leaps, so avoid attacking him during these times, and try to minimize weapons or gear that deal damage over time during this encounter, as the invincibility will interrupt those effects.
Best Strategy
Since Xyclucian can deal cold, fire, and lightning damage to you, be sure to balance your resistances when building a build to challenge him, and focus on the one you are least vulnerable to.
In most cases, the boss’s back area is the safest place to be during this fight, as attacks like Flamethrower, Poison Lob, and Lightning Breath cannot hit him from behind, so you may need to stay in this safe area for a long time.
Once you have passed the above tests, you will have completed your encounter with Xyclucian, The Chimera, and will receive a notification to unlock Chimeral Inscribed Ultimatum of Trial of Chaos and complete Legacy of the Vaal main quest.
The above are some specific methods and strategies for finding and fighting against Xyclucian in the current POE 2 Early Access. I hope that with the help of this guide, you can complete this encounter as soon as possible and unlock the more challenging Trial of Chaos to get more loot from it. I wish you a happy game!

Path of Exile 3.29's Scion may be the luckiest class, as she not only receives many powerful nodes from the updated Reliquarian Ascendancy but also gains access to the brand-new Luminary Ascendancy class.
Luminary Ascendancy is closely tied to Mercenary system. You can either use Mercenaries as powerful support units to increase your damage, or build around them as independent fighters. Mercenaries may seem similar to powerful minions, but there are significant differences between the two.
Mercenary Core Mechanics
The biggest advantage of Luminary lies in breaking the limitation that Mercenaries cannot be permanently hired. Normally, Mercenaries only exist temporarily, but Luminary allows you to permanently recruit them and freely customize their equipment.
You can have up to three Mercenaries at the same time. One of them can actively fight alongside you as an allied unit, while the other two remain on standby in towns or hideouts and can be swapped in whenever needed.
Mercenaries can still die during combat, so keeping them well-equipped is essential. If they fall in battle, you only need to pay a certain amount of Gold to revive them in the next area.
During the campaign, you can travel to The Grand Arena in Act 4 or The Hidden Underbelly in Act 8, where a powerful Mercenary will always be waiting to be recruited.
Keep in mind that Mercenary passive stats and skill levels automatically scale with the level of the current area. However, the maximum item level of their equipment is permanently locked to the level of the area where they were first discovered. This means you will still need to search for higher-level Mercenaries and replace them later in the game.
Luminary Ascendancy Nodes
For defense, Luminary has two important Ascendancy nodes. Loyal Bodyguard allows your Mercenary to absorb part of the damage when your Life is low. When you have more Life than your Mercenary, damage taken by your Mercenary will instead restore Life for you.
Another node, Bestowed Knighthood, grants your Mercenary the ability to Taunt enemies and increases their skill range, allowing them to draw enemy attention more effectively.
For offense, Unique Arms is the core node. It allows Mercenaries to equip all Unique item slots except the chest armor slot, and they gain a massive damage increase based on the number of Unique items they have equipped. You can equip your Mercenary with multiple damage-focused Uniques, turning them into a walking damage amplifier.
Luminary Ascendancy Builds
Luminary mainly has two different playstyles: using Mercenaries to enhance your own build or making Mercenary the primary DPS source.
Using Mercenaries as Support
If you want your Mercenary to act as a support partner, equipping them with the right Unique and Rare items can provide incredible benefits.
For example, in a Lightning damage build, equipping Perquil's Toe on your Mercenary can directly provide 30% more damage while only taking up one Unique slot, making it extremely efficient.
Mask of the Tribunal provides up to 80% Critical Strike Damage and 40% Cast Speed for nearby allies by stacking Mercenary's attributes, and it can be further improved with Corrupted modifiers.
If you need physical defense, Kaom's Binding allows your Mercenary to effectively reduce the physical damage you take from enemies.
Besides Unique items, Rare equipment on Mercenaries should not be overlooked. You can use modifiers, or anointments to boost Mercenary. You can also equip gloves or rings with Curse on Hit modifiers, allowing Mercenary to apply additional curses to enemies.
At the same time, stacking Aura Effect modifiers on weapons, shields, helmets, and other equipment slots can significantly increase the strength of the Auras activated by your Mercenary.
Some Mercenaries naturally come with two Aura skills, which are the foundation of Luminary support playstyle. It is worth noting that these Auras can reach around level 26 to 28 on a level 83 Mercenary, far exceeding the level of Auras a player can normally activate themselves. This makes these Mercenaries extremely powerful.
Mercenaries as Damage Dealers
Another completely different playstyle is to personally support your Mercenary and make them the main damage dealer. In this case, you can use Flame Link skill, which grants the linked target additional Fire flat damage based on your maximum Life. This means stacking Life not only improves your survivability but also directly increases your Mercenary's damage.
Ascendancy node Oath of Lealty allows Link skills to have unlimited duration, reduces their cost by 50%, and prevents you from dying when your Mercenary dies, greatly improving overall reliability.
Mercenary Selection
If you want your Mercenary to deal damage directly, you must have a deep understanding of their skill pool. Every Mercenary has a fixed set of Primary Skills that cannot be changed. Mercenaries with movement skills often perform poorly because their AI frequently uses jumps or movement abilities, wasting a large amount of time that could have been spent attacking.
Secondary Skills are the key factor that determines their damage ceiling. If a Mercenary has multiple Secondary Skills, especially including weaker versions, AI will randomly choose between them, greatly reducing efficiency. Therefore, it is better to look for Mercenaries that only have the ideal skills.
As for Utility Skills, movement abilities should also be avoided. It is better to choose skills that provide passive bonuses.
It is important to remember that not every Mercenary is harmless. Some of them can be extremely dangerous in combat, especially for Hardcore players. If you encounter a rare Mercenary, it is best to check their skills first before deciding whether to challenge them, otherwise you may suffer an unexpected defeat.
Mercenary Warrant
In PoE 3.29, Mercenary Warrant items can be used to make a specific Mercenary appear on your map.
Even if you are unlucky and fail to encounter your desired Mercenary, you can directly trade for Mercenary Warrants from other players and use them with your map. After defeating Mercenary, you can immediately recruit them. This ensures that you can obtain Mercenary you want.
During trading, you can check Mercenary's skill combination through the interface. More importantly, you can inspect their Support Gem links. The choice of Support Gems directly determines Mercenary's actual performance.
Since high-quality dual-Aura Mercenaries are extremely rare, they often hold significant value in PoE currency. Therefore, even if you do not plan to use one yourself, it is still worth watching for popular combinations that may provide strong trading opportunities.
Gear Crafting
During the early campaign, you can use the crafting bench to create basic flat damage modifiers or percentage-based elemental attack damage modifiers for Mercenaries. These modifiers mainly appear on amulets, rings, weapons, and gloves. Belts provide additional damage, while the remaining armor slots only need Life and resistances to ensure Mercenary survives.
Later in the game, if you want to pursue the strongest setup, you can build around modifiers such as Aura Effect or armor stacking to create endgame equipment. However, keep in mind that Unique item slots are limited, so you must make careful choices.
Luminary Ascendancy and permanent Mercenary system will bring many exciting possibilities to Path of Exile. Among them, dual-Aura Mercenaries are especially worth watching. They may become some of the most valuable Mercenaries and could become one of the most sought-after trading options in Curse of the Allflame League.
There is less than a day left until the launch of Path of Exile 3.29! Have you decided whether to stick with a familiar setup or hunt down a top-tier build using various guides? Regardless, we highly recommend trying out Essence Drain Build combined with Contagion!
This isn't exactly a brand-new playstyle; if you've played through multiple PoE leagues, you've likely heard of this build before. We're bringing it up again because buffs to specific skills and gear have improved Essence Drain Build's performance.
Potential performance in 3.29
Based on the known update details for Path of Exile 3.29, Essence Drain Build should offer a great experience during both the league start and the endgame, though the endgame version may require some adjustments to your gear or skills.
Overall, the core damage mechanic involves casting Contagion followed by Essence Drain. If you encounter monsters that aren't instantly killed, you can finish them off with Bane; during the league start phase, you can also incorporate Blight as a supplementary skill.
Blight is particularly helpful against single targets, though you generally won't need to use it frequently once you reach the endgame. Additionally, Wither effect is excellent and can even trigger automatically if you use a specific staff setup.
More importantly, since 3.29 league includes buffs for several skills relevant to this build, such as Blight, Essence Drain Build will benefit from a larger AoE and even improved visual effects.
Class and skill combinations
As you know, your choice of class or Ascendancy in PoE doesn't strictly limit your skill gem combinations. However, if you want to craft a specific build, choosing the right class allows it to perform at its best.
For Essence Drain Build in 3.29, Occultist looks like a solid choice. It offers interesting scaling options, and the base class, Witch, provides a wide range of gameplay possibilities.
However, Occultist relies heavily on Power Charge mechanic. Since many PoE builds utilize this same mechanic, completing the full gear setup for Essence Drain Build might require a larger investment.
That said, if you don't mind this point and have the budget, choosing PoE currency for sale on POECURRENCY.com can easily solve this issue. Simply by stockpiling more currency, acquiring or upgrading your gear becomes an easy task.
More importantly, 3.29 league introduces Unhallowed Rite for Occultist, a new Notable passive skill tailored for channeling skills. Based on its known effects, it pairs exceptionally well with Blight.
In 3.29 league, Blight receives a buff: the base radius of its effect increases by 0.2 meters at all levels, and the base chaos damage rises to 469 per second when the gem reaches level 20.
Additionally, incorporating Spellslinger during the early-game progression, combined with Eldritch Battery, Vile Bastion, and Mind over Matter, significantly boosts the build's sustainability, ensuring a much smoother leveling experience.
As you transition into the endgame, adding Forbidden Power grants a massive boost to AoE. When combined with the radius and chaos damage enhancements (at level 20) for Contagion, the build's overall coverage becomes truly impressive.
In fact, Essence Drain Build prior to 3.29 league faced a major issue: they required a massive investment of resources and skill slots just to function effectively. For instance, you needed to slot in numerous chaos skills just to achieve decent single-target damage output.
However, the radius and damage buffs brought to Bane, another key skill, by Curse of the Allflame league effectively resolve this problem. Furthermore, the duration of Bane debuff now increases by 100% for every curse applied during combat, up from the previous 50%.
What gear do you need?
For Contagion + Essence Drain Build, most of the required gear drops relatively easily, even in SSF mode; you simply need to invest currency later on to improve quality or reroll for better modifiers.
Of course, if you're aiming for peak performance, a few specific rare items are essential, such as various Relics, Badge of the Brotherhood amulet, or Anathema ring, though most other components are standard gear, like Cane of Unravelling staff.
Even more interesting is that this important, yet easily obtainable, piece of gear received a buff in 3.29 league, specifically one that ties its benefits closely to Power Charges.
Cane of Unravelling now grants +1 to your maximum Power Charges; additionally, for every Power Charge you possess, you gain a 5% increase in cast speed and 5 points of mana regeneration per second.
The only issue with this build is that the base setup doesn't generate Frenzy Charges; however, once you reach the endgame and incorporate the rare items mentioned earlier, you can align your maximum Frenzy Charges with your maximum Power Charges.
Furthermore, you need to stack resistances as high as possible, ideally hitting the cap. It doesn't matter whether these resistances come from your rings, belt, or amulet; that depends entirely on your personal setup.
Clearly, the strength of Essence Drain Build in 3.29 league lies in a series of incremental improvements that combine to deliver a superior overall performance. If you don't want to miss out on these exciting changes, why not give this build a try for your league starter?
Players, with only two days left until Path of Exile 3.29 Curse of the Allflame, our preparation time is running out. We'd better make sure we understand the class changes before the new challenge league begins.
As for Assassin class, it also receives significant mechanic adjustments in PoE 3.29, transforming it from a long-standing niche choice with only 1% to 3% usage to a highly competitive and powerful Assassin for specific build directions.
While the core issues related to Assassin's Poison mechanic haven't been resolved, we can leverage the Instant Leech mechanic and Bifurcated Critical Strikes to provide substantial damage and healing for hit-based builds.
Poison System Dilemma
The reason Assassin's usage rate has been so dismal in previous versions of PoE is ultimately because of the poor synergy between its Poison and Critical Strike systems.
In PoE 3.29, Poison didn't receive any substantial buffs; in fact, it was indirectly weakened by the removal of Awakened Support Gem - Damage over Time builds rely more heavily on gem levels, making the negative impact more pronounced.
Furthermore, there's still a clear mechanic conflict between Perfect Agony and nodes. Even nodes that don't synergize with it can't be used effectively, making Poison crit builds logically inconsistent.
While some nodes have decent stats, considering the significantly weaker relative strength of Poison in Curse of the Allflame environment, these nodes don't perform ideally in actual combat.
Core Nodes Evaluation
Left-Side Nodes
The left-side nodes of Assassin tree didn't undergo fundamental changes in Patch 3.29, but some still retain practical value.
Shadowed Blood
This node provides immunity to Damaging Ailments, offering some utility in certain PoE combat scenarios. It's not entirely useless, but the trade-off of a Notable Ascendancy passive skill is worth considering.
Mistwalker
Mistwalker provides Assassins with an attack dodge chance and movement speed bonus based on Elusive effects. At 100% Elusive amplification, it averages about a 30% movement speed increase and a 15% hit damage dodge chance, making it a decent choice.
For the Jugular and Knife in the Back
These nodes work on low-health and non-low-health enemies respectively, but we can acquire them simultaneously through Forbidden Flesh and Forbidden Flame, stacking them for 100% more Critical Strike Chance and +100% to Critical Strike Multiplier, resulting in extremely high damage potential in a well-developed build.
Right-side Nodes
The key update to Assassin in Path of Exile 3.29 lies on the right side of the tree, where two nodes fundamentally change the utility and power of Assassins.
Deathmarked
First, this node provides a 10% effect boost for each Power Charge it holds, and each Power Charge grants 3% Instant Leech.
For example, with 10 Power Charges, this achieves a 30% Instant Leech rate, six times Instant Leech effect of general passive skills.
This recovery ability is particularly powerful for high-attack-frequency, high-accuracy characters, effectively solving the problem of sustained combat recovery in the late Path of Exile content.
However, it's worth noting that Deathmarked isn't limited to Life Leech, so it also applies to Energy Shield and Mana Leech, making it suitable for defensive systems like Eldritch Battery and Mind Over Matter.
Bifurcated Critical Strike Damage
This node has a double-check mechanism, meaning that if either of the two critical strikes is a critical strike, then the entire attack is considered a critical strike.
If both strikes are critical strikes, you will receive an additional 100% more Critical Strike Damage.
For builds with a critical strike chance close to or at 100%, Bifurcated Critical Strike Damage effectively provides a permanent 100% more Critical Strike Damage, making the benefit particularly significant.
Additionally, this node only reduces spell critical strike chance, so its impact on offensive builds or builds that rely on spells triggered by attacks is relatively small.
Resource Management Optimization
Another major value of the updated Assassin nodes lies in the effective management of Mana and Energy Shield resources.
Instant Leech, combined with Eldritch Battery to convert Energy Shield into Mana, and then with Mind Over Matter to transfer some damage taken to Mana, allows Assassins to achieve multiple synergies of defense, Mana Regeneration, and Life Regeneration.
Compared to the traditional Energy Shield system in PoE that relies on Recharge, Instant Leech is unaffected by combat interruptions and has a higher recovery efficiency than conventional methods.
This mechanism perfectly compensates for Assassins' weakness in defensive layers, giving them good survivability even in the late game of Path of Exile 3.29 after gearing up.
Assassin's Competitiveness
Although Assassins already possess top-tier damage caps and recovery capabilities in Curse of the Allflame, their competitiveness in the early stages of new leagues will still face strong challenges from Witch classes.
Occultist boasts excellent Notable Ascendancy passive skills like Forbidden Power and Vile Bastion, while Elementalist provides stable defense and healing through Golems in the early game, resulting in a higher overall margin for error.
Therefore, Assassin might be more suitable as a second build choice during progression, but once you have sufficient gear and a Power Charge system, you can fully unleash its full potential with Instant Leech and Bifurcated Critical Strikes.
Players, if you're aiming for maximum damage in PoE 3.29, then Assassin is now a top-tier option you can't ignore!
The campaign content of Path of Exile is not inherently dull, yet for players eager to reach the endgame, it often feels like little more than a time sink. Even seasoned veterans typically need around a dozen hours to clear all ten acts.
Nevertheless, the developers have tucked plenty of clever details into the campaign - especially since PoE 3.24, which added significant new content to Acts 6–10. We will skip the hidden tricks in Acts 2–5 here, as they are mostly cumbersome, offer mediocre rewards, and aren't new additions.
Some players may have missed these features, but they could help you speed through the campaign in PoE 3.29 Curse of the Allflame.
Act 1 - Chemist Strongbox
In The Upper Prison of Act 1, just before the confrontation with Brutus, a strongbox icon will appear on your minimap. As you approach, you will see that it sits alone in a room at the back, enclosed with no visible entrance.
The mechanism lies on a stone pillar in the middle of the corridor. After you trigger the switch, a skeleton will collapse, and the passage will open.
This is a Chemist Strongbox, which contains various flasks. You stand a good chance of obtaining a Quicksilver Flask, giving you two of them early on for faster movement through the zones. Of course, it may also yield mana flasks, life flasks, or other types.
Act 6 - Free Tattoo
In Karui Fortress of Act 6, just before you face God of War, a small island sits in the centre of the area. Monsters styled after those from Trial of the Ancestors occupy this island; defeating them drops one free Tattoo.
Act 7 - Quality Gem
In Chamber of Sins Level 2 of Act 7, the zone features an exit and also spawns an Ascendancy Trial. After you locate and complete the trial, look for a switch on the back wall of the trial's endpoint room - you may need to search briefly.
Activating the switch opens a small door beside it. Inside, a Hidden Gem chest holds a gem with Quality.
Act 7 - Smuggler's Cache
Near the end of Act 7, after defeating the act boss Arakali, you arrive at Sun Ramparts. Follow the wall closely; in the early stretch of the ramparts, you will spot a very conspicuous wooden lever. Pulling it opens a tunnel area. Inside the tunnel, you will find both a strongbox and a Smuggler's Cache.
Act 7 - Corrupted Unique
Also in Act 7, within Temple of Decay Level 1, once you reach the centre of the zone, you will see rooms that look notably red on one side. These include Corrupted Arms, Corrupted Armor, and Corrupted Prized Arms. The first two grant corrupted rare items, while Corrupted Prized Arms drops a corrupted unique item.
Act 8 - Chemist Strongbox
In Grain Gate area of Act 8, you can find another Chemist Strongbox. This strongbox may provide you with an extra Quicksilver Flask, or useful flasks such as Diamond Flask and Jade Flask.
Additionally, within the Grain Gate zone, a book reveals the location of Gemling Legionnaires. You need to defeat these monsters to receive quest reward points from Maramoa.
Act 8 - Hidden Underbelly
Near Grain Gate area, a huge crane stands. Beside its base is a conspicuous blue circular manhole cover. Click on it to open the cover and enter Hidden Underbelly.
This is a transitional zone that essentially serves as a shortcut. Traversing Hidden Underbelly gives you access to both The Solaris Concourse and The Bath House. If you exit from The Bath House side, you will find yourself very close to an Ascendancy Trial.
Act 8 - Scouring Orbs
Inside The Bath House of Act 8, there is also a Private Chamber that contains a chest. Opening it yields 2 to 3 Orbs of Scouring.
Act 8 - Free Unique Item
In The Lunaris Temple of Act 8, the floor is covered in blue carpets, but in one corner you can find a white tile with a golden circular pattern in its centre.
When you stand on it, a line of dialogue appears in the chat box on the right, and the surrounding braziers ignite. A similar tile exists in The Solaris Temple Level 1 as well.
After triggering both prompts, head to The Grand Promenade. At a specific spot, you will discover a door that does not normally appear, with an emblem on the ground that bears both solar and lunar symbols. Go up the stairs into the inner room and open Twilight's End chest there to obtain a free unique item.
Act 9 - Rare Jewel
In Act 9, after you enter Vastiri Desert, a small area lies to the right of the entrance, with several statues standing there.
Among them are the Crimson Offering, Verdant Offering, and Sapphire Offering. Choose one of them, and the other offerings will crumble. You will receive a rare jewel corresponding to your chosen offering.
Act 9 - Fossils
On your way to defeat Gorgon, you can choose to follow the left wall. This path leads you to a camp, where two fossil remnants are found. Click on them to obtain two free Fossils.
Act 9 - Refinery Crafting Recipe
In Refinery, follow the railway tracks, and you will find a crane similar to the one in The Grain Gate, which opens the way to a hidden underbelly area. Entering Refinery tunnels, you will encounter monsters, and you can also find a Crafting Recipe.
Act 10 - Facetor's Lens
When you enter Bone Pits in Oriath, locate Ascendancy Trial within. On one side of the trial area there is a switch; after activating it on the other side, a hidden door opens.
Inside the chest beyond that door, although it appears to hold a hidden gem, what you actually obtain is a Facetor's Lens. It stores 10 million experience points, which you can apply directly to any gem of your choice.
These are just a few of the hidden items found in Path of Exile campaign. While their value might be negligible to players who have already reached the endgame, they are very helpful for those still progressing through the story. Similar hidden content exists in Acts 2 through 5 - waiting for you to discover it yourself.
