Allrounder Build Guide in POE 3.20: Explosive Arrow Ballista Elementalist for League Start

Since its stable release, nearly every league in Path of Exile 1 has had a unique theme and core league mechanics that complement it. Combined with old changes, all new leagues offer an upgraded gameplay experience based on the existing PoE experience.

After the livestream, the core gameplay of 3.27 Keepers of the Flame league, which launches on October 31, 2025, was finally revealed, along with all the new changes and content.

Interestingly, 3.27 Keepers challenge leagues not only introduce a new story but are also essentially an extension of the established Breach mechanic. Below, we'll provide a detailed introduction to the core mechanics and other key changes to 3.27 league.

What Is Breach?

To fully experience Keepers challenge leagues, you first need to have a detailed understanding of Breach mechanic itself, not just how to earn rewards from it.

Breach was introduced as early as 2016 with the eponymous PoE 1 league and has since been retained in the base game. After years of refinement and adjustments, it has now become a mature endgame feature.

Regular Breaches spawn randomly on the game map and can be identified by a hand icon within a purple circle. Approaching them triggers a Breach and begins clearing the monsters spawned within. Each Breach lasts for at least 30 seconds, extending up to 60 seconds.

Note that to claim PoE currency dropped, you must kill breach monsters. Furthermore, enemies spawned by Vaal Breach do not drop XP or other items.

Breach In Keepers Of The Flame Challenge League

In fact, not only are the mechanics closely related, but 3.27 league itself can be considered a sequel to 2.5.0 Breach League.

In this new league, the evil Breachlords plan to expand their influence in Wraeclast. To combat them, Ailith has created Order of Keepers of the Flame. Your goal is to join Ailith in destroying all Breach monsters.

Upon entering Mud Flats area, you'll find it overrun by Breach monsters attempting to establish their lair. Ailith's fire powers are effective against them, provided you can help her fend off their attacks.

If you encounter an Unstable Breach caused by the massive Breach Hand, more monsters will emerge, requiring you to quickly defeat them to ensure Ailith can safely clear them with her fire.

After Breach stabilizes, Vruun, Marshal of Xesht, will appear as a boss. You must defeat him to permanently seal Breach and claim your rewards.

What Is Genesis Tree?

As your collaboration with Ailith deepens, she will eventually lead you to Monastery of Keepers, where you can unlock Genesis Tree. Think of it as a specialized Mastery Tree, where you invest points to earn rewards and special Grafts.

Grafts are a new way of granting buffs. By fusing breach hands with your character, you gain access to a variety of new active and passive skills, with up to 16 Grafts to choose from.

Once these Breach hands are implanted, you can collect Graftblood from defeating Breach monsters in battle. This Graftblood can then be invested in Genesis Tree to accelerate its growth, unlocking more rewards.

Grafts not only grant additional skills, but also modify your gear. However, grafted gear cannot be modified or reset with standard currency. Fortunately, Genesis Tree itself offers a very good node investment.

How To Complete Keepers Challenge League?

Based on the core mechanics described above, you can choose to complete 3.27 league in standard, hardcore, or solo self-found modes, depending on your ability.

These three modes share the same core mechanics, but you can create private leagues and add mods to enrich the gameplay, customizing your own Keepers challenge league.

Keepers Challenge League includes 40 new challenges and 8 Ruthless Keepers Challenges. Completing a certain number of challenges in both challenge modes gives you a chance to receive pieces of Keeper of the Flame Armor Set, a 3.27 league-exclusive reward.

In addition, starting with Challenge 19, every three challenges you complete will earn you pieces of Keeper Totem Pole decoration.

The completed totem pole will then remain permanently in your hideout, representing the number of challenges you've completed during 3.27 league.

New Bloodlines System

In addition to utilizing Genesis Tree, Keepers of the Flame League introduces another new mechanic: Bloodlines. Think of them as secondary Ascendancy classes that can be enhanced by allocating Ascendancy passive skill points.

Reliably, there are no restrictions on the use of Bloodlines; as long as you earn a Bloodline by killing an endgame boss, you can pair it with any Ascendancy class you already own. A total of 10 Bloodlines are available.

It's important to note that Bloodlines and Ascendancy classes share the same passive skill points, so it's crucial to carefully consider your needs when allocating them to ensure each skill point is maximized.

Asynchronous Trade Finally Launches

Ever since the initial leaks of 3.27 league, many players have been eager for Path of Exile to implement asynchronous trade or other similar mechanisms in this league, aligning it with PoE 2 and making the game's trading system more convenient.

So, once 3.27 league launches, as long as you've unlocked Act 6, you can visit Faustus in Lioneye's Watch and have him manage your Merchant's Tabs. This way, other players can automatically trade with you even when you're offline.

If you acquired Premium Stash Tabs before 3.26 league launched, you can unlock asynchronous trade using Mercant's Tab Upgrade tool on the game's official website. If you already have Merchant's Tabs unlocked in PoE 2, you can use them directly in 3.27 league.

The new content we've introduced here focuses primarily on mechanics and gameplay, but Keepers of the Flame will also bring many more subtle changes, such as new gems. Once the league launches, you can explore it in depth!

As development on the second game stabilizes, Path of Exile 1 league updates have returned to their normal frequency. Previously announced to begin on October 31st, 3.27 league recently released a trailer and detailed a range of new features.

Named Keepers of the Flame, this league will feature both gameplay changes and new content, focusing on gameplay and other details that impact your gaming experience. We'll explain these changes below.

What Changes Will The Heist Mechanic Undergo?

As you know, Path of Exile 1 will continue to improve and enhance the well-received mechanics and gameplay of the previous leagues as it updates, ensuring they continue to serve you well. This is one of the main reasons the game's scale continues to grow.

The heist mechanic, introduced in 3.12 league, has undoubtedly become a core component of the game, featuring complex entry and completion mechanisms, and, of course, rich rewards.

Unfortunately, with the introduction of new mechanics, more and more players believe that the rewards are far less valuable than the effort required to complete the early Heist missions, ultimately leading to a decline in both participation and appreciation for the mechanic.

To address this, starting with 3.27 league, rogues available in heist missions will automatically start at the highest level, allowing you to farm loot directly in heist locations, eliminating the need to slowly level up rogues by completing contracts from scratch.

Of course, streamlining the system will lower the barrier to entry and difficulty of obtaining rare heist rewards. This may result in a reduction in the amount of PoE currency dropped and a lower drop rate for rare gear or gems to achieve balance.

But honestly, the impact of this balancing act is negligible compared to the redundant upfront work, as you can simply complete Heist missions more frequently to earn loot when you have the time.

At the same time, the improved efficiency of the heist system will also increase the circulation of currency in the game's trading market, making some rare items more accessible and making the trading system more meaningful.

It's worth noting that while the mercenary mechanic from 3.26 leaguewas very popular, it will not be carried over to the base game for now due to a slight imbalance in power and potential incompatibility with Path of Exile after the launch of 3.27 league.

However, the developers have stated that they are generally satisfied with the design of the mercenary mechanic in 3.26 league, so do not rule out the possibility of its return in a future League after a redesign.

Atlas Passive Tree Optimizations

As the primary way to enhance your character and builds in the game, Atlas Passive Tree has been undergoing continuous updates and adjustments.

You can earn a total of 132 passive points to invest in your Atlas Passive Tree, but it's inevitable that you'll need to reset part of your Atlas tree layout.

In League 3.26, which has yet to conclude, resetting your Atlas tree is only possible by consuming Orbs of Unmaking. While earning this currency isn't difficult, the flexibility you have in resetting it is very limited.

Keepers of the Flame League will implement changes to address this issue. In 3.27, you'll be able to directly refund all passive points you've invested using gold, and this mechanic will be applied to the rest of Path of Exile's regular passive tree.

This change will give you more choice and freedom when customizing your character's passive skill clusters, eliminating the need to worry about cumbersome resets that distract from building your passive skill system.

A More Balanced Class And Combat Experience

Maintaining a balanced experience across classes is a constant challenge in any ARPG with multiple classes. It's inherently impossible to make all classes play and power levels identical, requiring constant adjustments based on league content.

Thankfully, unlike PoE 2, PoE 1's class system has stabilized, making adjustments relatively easy and drastic. However, the likelihood of new classes being added is practically zero - at least not in 3.27 league.

On the other hand, combat experience is closely tied to systems like skill gems and support gems, and PoE frequently adds and updates these to fine-tune the overall combat experience.

We expect to reveal more about this update after 3.27 league livestream on October 23rd, as it will likely be related to the new gameplay features of the new league.

Will The Main Story Be Updated?

While storytelling isn't a hallmark of Path of Exile series, the game did generate significant buzz within the community around the release of 3.26 league, building on Secrets of the Atlas plot.

Based on the content released so far, Keepers of the Flame League doesn't appear to be planning to replicate this approach, but the possibility of updating the main story in a new expansion cannot be ruled out.

However, even if 3.27 releases a new story chapter, its primary purpose will likely be to set the stage for more significant plot twists later on, rather than bringing any major news, otherwise the development team would have already revealed it.

Changes To The Trading System

As one of the ways you acquire items and gear in PoE, the usability of the trading system significantly impacts the gameplay experience. A high-quality marketplace allows players to efficiently circulate currency and unused items, driving game development.

To this end, 3.27 league will feature adjustments to the trading system, including changes to the tabs and the loot drop rate adjustments we mentioned when introducing the heist mechanic.

The above is our overall prediction based on 3.27 league trailer and other information revealed by the development team. We expect a full reveal of the league's content after the livestream. So be sure to tune in! You'll have a chance to win Twitch Drops!

Patch 0.3.1 has been live for a few weeks now. As a beta update for patch 0.4.0, the main selling point of 0.3.1 was to test potential game changes before the next major update and, based on player feedback, to try to fix some bugs before the start of the new league.

Honestly, I think patch 0.3.1 was quite successful, but there are still many areas in the endgame that need to be fixed before the release of 0.4.0, which is what we will discuss here.

Patch 0.4.0 Release Date Speculation

The release date for Path of Exile 2 patch 0.4.0 has not yet been officially announced, but based on the developers' previously stated four-month league cycle, we can expect it to be released in late December 2025, with the possibility of it being pushed back to January 2026.

Since Patch 0.3.0, The Third Edict, was released on August 29, 2025, and given the developers' usual Friday release schedule, 0.4.0 will probably go live on January 2, 2026.

In any case, based on the updates in Patch 0.3.1 and player feedback, we'll discuss the much-needed changes to the endgame in the next League.

Delirium Mechanics

For this first section, we'll of course be discussing the changes to the endgame mechanics, especially the current Delirium, which absolutely destroys your FPS and turns the game into a complete mess.

For us, at least, the biggest positive change in Patch 0.3.1 was the removal of Delirium's incessant humming music. Honestly, I wish it had carried over to PoE 3.27.

Unfortunately, the visuals in Path of Exile 2's Delirium are just as terrible. The constant fog caused by Delirium Mirror turns the world into a gray haze and cuts our FPS in half or a third. However, the goal is to kill enemies in the fog, and there's a reward counter that determines the number of Distilled Emotions you'll receive after the fog clears.

These Emotions are currency for character enhancement and can also be used for crafting and upgrades. By killing monsters, especially those unique to Delirium encounters, you can increase the amount of Distilled Emotions dropped at the end of the encounter, and potentially even higher-level Simulacrum Splinters.

What's more, in PoE 2, Distilled Emotions, in addition to providing Delirium, also provide a significant bonus to the spawn rate of rare monsters in the map. This is effectively double dipping, meaning that if you don't use Distilled Emotions on every map, you're missing out on a very powerful loot multiplier. So, there's almost no reason not to use Emotions.

The problem is Delirium Mirror has always been criticized for its high difficulty, as it makes monsters more powerful while adding new, powerful monsters, and the challenge increases the further away from Mirror you are. Because of the extremely high difficulty and the fog's tendency to cause enemies to deal more damage and take less, players find these encounters frustrating and overly painful.

This would all be fine if Delirium Mirror itself provided some valuable PoE 2 currency, but since it only provides Distilled Emotions, why not just farm Simulacrum instead? It's not only easier to obtain, but also more cost-effective.

Simply put, in PoE 2, Delirium Mirror only provides Emotions and Simulacrum Splinters, but there have always been better ways to obtain both, making Delirium Mirror's existence essentially pointless.

Delirium Mirror is the only mechanic still wearing these special handcuffs. So, in Patch 0.4.0, either the Delirium Mirror reward needs to be buffed, or Emotions reward needs to be nerfed, or both.

Map Rolling Mechanics

On the other hand, Path of Exile 2's map rolling mechanics can be quite frustrating. The high-risk modifiers, the wide variance in map outcomes, and the poor layout of many maps make play throughs too long or too difficult, making them unpleasant.

Currently, map rolls in the game are polarized. Some map rolls with high-risk modifiers, such as a large number of monsters dealing increased damage, shock effects on hit, or a very high freeze chance, can make a map impossible to play, depending on the player's build.

Some map rolls may contain beneficial modifiers that are friendly to new players, but these offer little to no tangible benefit. Some of these junk items and minimal currency drops make the risk and effort seem meaningless.

Because of the wide variation in modifiers and the varying number of beneficial and harmful modifier effects, the differences between maps can be significant, often leading players to waste significant amounts of money and time trying to find a manageable map.

Furthermore, poor map layouts are a significant contributing factor to players' perceived endgame experience being so poor. Many maps not only feature narrow, winding paths and numerous obstacles, making navigation cumbersome but also increasing the chances of being cornered by monsters.

The combination of larger maps and slower movement speed modifiers means that even completing a single map can take a long time, which many players find tedious and uninspiring.

More importantly, the high-risk, low-reward nature of many maps, coupled with harsh death penalties, makes the game feel punishing rather than rewarding success. Some players feel that the current endgame map system is less rewarding and engaging than Path of Exile 1.

Atlas Passive Skill Tree

The next issue is the skill tree, which is currently quite confusing. This is because the new map system in patch 0.3.0 adds one to three additional items to each map. Unfortunately, these additional items can be anything: Essence, Breach, or other strongboxes.

This new randomized item system overrides the effects of many passive nodes, which in turn increases the chances of spawning the same item type. Furthermore, because of exploits and overwrite mechanics, numerous Atlas passive nodes, such as Essence, Strongboxes, and Rogue Exiles, appear to be bugged and not functioning as intended, rendering many nodes useless.

Furthermore, the cost of certain bosses required for Atlas progression and the single-portal nature of Atlas progression make Atlas Points prohibitively expensive for average players, leading to frustration.

To unlock new Atlas Points, players must defeat bosses like King in the Mists, which costs approximately six PoE 2 Divine Orbs per attempt.

Since these bosses only have a single portal, if the player dies, they lose the portal fee, Atlas progression, and the opportunity to unlock that specific point. This makes the process particularly challenging for average players who may not have the gear or skills to guarantee victory on their first try.

Thus, the 0.4.0 patch's changes to the passive tree are urgently needed. These are fundamental changes that will directly impact players' ability to earn loot, currency, and waystones, making the endgame more interesting and meaningful.

Regardless, as of update 0.3.1, Path of Exile 2's endgame setup in patch 0.4.0 still needs a major overhaul, but this also proves we're getting closer to the full game's release.

If you want to gain an advantage in patch 0.4.0, you need to prepare now. Not only will you need to learn new build strategies and explore Atlas settings, but having enough currency is essential for everything. However, there's a shortcut: you can buy cheap PoE 2 Currency on POECurrency.com platform for a better gaming experience! Good luck!

Although updates to Path of Exile 1 were delayed for nearly a year late last year due to the development of Path of Exile 2, 3.26 League launched in June of this year, returning the original game's league update schedule to normal.

With this in mind, Path of Exile development team recently announced that League 3.27 will launch on October 31st, culminating in the conclusion of Mercenaries of Trarthus League and the release of 3.27 livestream.

Building on 3.26's foundation, the new league is expected to further enhance Path of Exile 1's trading system, rebalance the meta, and bring additional improvements and changes to Atlas Tree and endgame content.

Below, we'll cover the known schedule and potential new changes for Path of Exile 3.27, focusing on these key areas.

Path Of Exile 3.27 Schedule

In addition to the confirmed release date for League 3.27, the development team is expected to hold a livestream on October 23rd PDT to announce more details about the new league. The official name of 3.27 will probably be announced even sooner.

It's important to note that the currently ongoing 3.26 expansion will not end immediately before 3.27, but will instead conclude on October 27th PDT. If you need to finish up work for that league, you'll need to plan ahead.

Will 3.27 Retain The Mechanics Of 3.26 League?

If you're a die-hard Path of Exile 1 fan, you know that nearly every league has its own unique mechanic, some of which are so popular that they're carried over to the new leagues. In League 3.26, that mechanic is undoubtedly the mercenaries system.

Unfortunately, while mercenaries are fun to play against and use as allies, their overall strength makes their integration into the core game unlikely.

Although the role of the mercenary system was previously reduced in 3.26.0c, it's likely to be nerfed or redesigned if it continues to be used in new leagues.

But honestly, even if you're a fan of the mercenary mechanic, there's no need to be disheartened, as 3.27 expansion will undoubtedly introduce new league gameplay, allowing you to earn more PoE currency in the new leagues.

Of course, the mechanics from older leagues that have been retained should still be available in 3.27, but adjustments are possible.

What Changes Might 3.27 Introduce?

Before getting into the new content, it's important to note that Merchant Tabs and offline buyouts have been implemented in PoE 2. However, if you convert a Premium Tab to a Merchant Tab, you won't be able to access them in PoE 1.

This makes it imperative that the same tab system be implemented in Path of Exile 1, as otherwise it would create further issues with the trading system.

However, it's impossible to say for sure whether this update will be implemented in League 3.27. To avoid trading difficulties in the new leagues, it's best to refrain from switching tabs in PoE 2 for now.

More QoL Changes About Trading

In expansion 3.26, the game improved the efficiency and experience of PoE currency farming by introducing QoL changes such as map level adjustments and quick-apply currency buttons. Similar changes are expected to continue in 3.27.

Building on these improvements, the game may release further trading optimizations to help you earn more income through efficient trading, such as:

• Making consumable items like fragments, essences, and fossils easier to sell at scale, reducing profit margins while increasing trading volume and boosting game vitality.
• If you're one of the first players to unlock Atlas, you'll be able to earn currency through trading without leaving the map, widening the gap between you and lower-level players.
• Reducing trading profit margins while ensuring that niche items still have high value will maintain a balanced trading market.

Additionally, the map device Rucksack, the quick currency use feature for interactable items, and the improved controller targeting introduced in expansion 3.26 are expected to remain available in 3.27.

How To Prepare For The New League?

Since the new gameplay and league system for League 3.27 have yet to be announced, the best you can do now is develop and familiarize yourself with a strategy that works with your regular farming plan to quickly acquire sufficient resources once the new league begins.

With this in mind, we offer the following specific recommendations:

• Enter the endgame as soon as possible and farm for currency.
• Gain early crafting fuel and currency by exploring Essence and chest nodes.
• Focus on farming mechanic paths like Harbinger or Expedition to quickly capture nodes.
• Update your loot filters promptly.
• Adjust your elemental resistance caps and spell suppression caps promptly.
• Plan your initial 15-20 Atlas passive points and adjust them accordingly once League 3.27 launches.
• Focus on unlocking bench crafts that grant elemental damage to spells and use essences for early weapon upgrades.
• Gain +1 skill level with skill gem modifiers through drops, Fossils, or advanced crafting.
• Try out more available builds to gain a combat advantage faster once the new league begins.

Over the next two weeks or so, the development team will continue to announce more details about the new content and changes coming to Path of Exile 3.27 through various channels, so stay tuned!

When entering a new league, you may experience increased damage in combat due to the difficulty adjusting to the new mechanics. Therefore, it's best to buy PoE 2 currency on POECURRENCY.com in advance.

This will allow you to immediately add more defensive affixes to your new league gear roll, giving you greater survivability and allowing you to steadily progress in 3.27.
