PoE 3.27 in Historical Context
Path of Exile 3.27, Keepers of the Flame, launched on October 31, 2025. The expansion paired a challenge-league encounter with major changes to trade, character balance, the Atlas, and older league systems. This guide is a verified retrospective based on GGG's official Content Update 3.27.0 notes, not a recommendation for the current league.
That distinction matters because patch 3.28 later made the revised Keepers and Breach content core. The Genesis Tree remained, Graftblood became Hiveblood, and players could no longer grow Grafts. GGG documented those carry-forward changes in the Content Update 3.28.0 notes. Values below describe their 3.27 state unless a later change is stated directly.
The useful way to read this patch is to separate its league systems, exact balance changes, and later status. That keeps a historical number from being mistaken for live build advice.
Key Takeaways
- Keepers introduced a new Breach loop. Players helped Ailith fight Hiveborn encounters, gathered league resources, and developed the Genesis Tree for rewards.
- Grafts used their own equipment and crafting rules. They occupied dedicated slots, granted stats or skills, and interacted with Implant currency instead of ordinary item crafting.
- Bloodline Ascendancy classes expanded character planning. Ten secondary classes launched in 3.27, unlocked from endgame bosses, and shared the character's existing Ascendancy-point pool.
- PoE 1 received asynchronous trade. After reaching Act 6, players could recruit Faustus and list items in a Merchant's Tab for offline sales.
- Defense and minion rules changed. Spell Suppression prevented 40% rather than 50% of suppressed damage, while minion attacks became unable to miss.
- Several underused skills received direct buffs. Chain Hook of Trarthus gained much wider chaining, and Cyclone variants dealt 20% more damage.
- Many 3.27 details are no longer current. Keepers became core in a modified form, Grafts stopped being obtainable, and later patches changed the endgame again.
The sections below focus on changes that affected how players interacted with the league, built characters, traded items, and approached the Atlas.
Keepers League, Grafts, and the Genesis Tree
Ailith led the Keepers against Hiveborn creatures emerging from Breaches. A league encounter could culminate in an Unstable Breach, and its resources fed progression at the Genesis Tree. The tree could grow currency, equipment, Unique items, and Grafts, so it worked as both a reward system and a source of league-specific character power.
Grafts were not ordinary gloves, jewels, or passive-tree items. A character equipped them in dedicated Graft slots. Their modifiers could provide stats, triggered effects, or skills, and Implant currency modified them. That distinction is important when reading an old build or trade discussion: a 3.27 setup that depended on a Graft cannot simply be recreated with a current rare item.
The tree also supported deliberate reward choices rather than a single linear upgrade path. Players decided what to grow and how to spend the league's resources. That made the mechanic relevant to both mapping and character planning without guaranteeing that every Graft or reward branch was equally valuable.
📌 Historical status: the Genesis Tree survived the move to core in 3.28, but Grafts did not. Treat any 3.27 Graft setup as league-specific unless a current source shows an equivalent mechanic.
Keepers Hardcore used a special parent-league rule. A character that died continued in Standard Keepers rather than leaving the Keepers environment entirely. This did not remove Hardcore from Path of Exile; it only described where a dead character from that challenge league moved.
Bloodlines and Endgame Progression
Bloodlines were secondary Ascendancy classes earned by defeating specified endgame bosses. Patch 3.27 launched with ten. A Bloodline could pair with any normal Ascendancy, but both trees drew from the same Ascendancy passive points. Unlocking one therefore added choices, not a free second set of points.
| Bloodline rule | What it meant in 3.27 | What it did not mean |
|---|---|---|
| Boss unlock | Each class was associated with a particular endgame boss and became available after meeting its unlock condition | Every character did not begin the league with all Bloodlines open |
| Secondary class | A Bloodline could be combined with a regular Ascendancy | It did not replace the need to choose and progress a normal Ascendancy |
| Shared points | Bloodline and regular Ascendancy passives competed for the same point pool | Unlocking a Bloodline did not double a character's Ascendancy points |
| Account planning | Boss access and point allocation shaped when a build could use its intended nodes | A planned endgame combination was not automatically a league starter |
Because the classes shared points, the real build question was which normal nodes could be given up for the Bloodline effect. A patch-note recap can explain that structure, but it cannot rank every pairing without a defined skill, budget, gear set, and encounter target.
Asynchronous Trade and Inventory Improvements
Patch 3.27 brought asynchronous item sales to PoE 1. Once a character reached Act 6, Faustus could manage Merchant's Tabs. A seller placed and priced an item in a tab, and an eligible buyer could complete the purchase while the seller was offline. GGG also added a full in-game Trade Market interface.
This reduced the need for both players to be online and ready for a manual hideout exchange. It did not turn every stash tab into an automatic shop or remove listing rules. The feature had its own access point and item flow, so players still needed to price items deliberately and understand which inventory held the listing.
Several smaller changes reduced repetitive clicks. Global Gold stacks increased by about 15%, and many bulk-currency trade fees fell. Town NPCs could identify all items without consuming Scrolls of Wisdom. Ctrl and right-click continually opened Stacked Decks; adding Shift dropped the revealed cards on the ground. The patch also added five stash affinities and one-click Gold refunds for both the character passive tree and the Atlas passive tree.
⚠️ Trade check: asynchronous sales solved the missed-message problem, not the pricing problem. Check the live market before listing an item, especially when reading a 3.27 currency estimate.
Essence interaction changed as well. Vaal Orbs replaced Remnants of Corruption as the currency used on trapped Essence monsters. A guide that instructs players to carry Remnants for that interaction is describing the pre-3.27 rule.
Player, Skill, and Support Gem Changes
The broadest defensive change reduced the default amount of damage prevented by a suppressed spell from 50% to 40%. Builds could still invest in Spell Suppression, but the same chance to suppress no longer produced the same baseline mitigation. At the same time, minion attacks became inherently accurate, and minion-accuracy modifiers were removed from skills, passives, and related itemization.
Several skill changes were large enough to affect damage calculations directly. They were not proof that a skill became competitively dominant, but they required old gems, planners, and guides to be updated.
| Skill or support | Verified 3.27 change | Practical reading |
|---|---|---|
| Chain Hook of Trarthus | Targeted up to 8 enemies, chained a maximum of 16 times, and dealt 25% more damage | Both its reach across a pack and its damage changed |
| Cyclone family | Cyclone, Cyclone of Tumult, and Vaal Cyclone dealt 20% more damage | Existing calculations needed the new gem values; the buff alone did not settle weapon or Ascendancy choice |
| Bladefall | Base critical strike chance rose from 6% to 10% | Critical investment began from a higher base value |
| Dark Pact | Base critical strike chance rose from 5% to 7%, and Skeleton-life sacrifice rose from 8% to 12% | Both hit scaling and Skeleton-based damage inputs changed |
| Pyroclast Mine | Its aura applied Fire Exposure instead of added fire damage; the regular gem dealt 35% more damage and applied -15% Fire Resistance | Old aura-stacking descriptions no longer matched the gem |
| Voltaxic Burst | Radius became 2.6 metres and cast time became 0.4 seconds | Archived gem calculations needed both patch-specific values |
| Energy Leech Support | It provided 15% to 24% more damage while on full Energy Shield and lost its more-damage-while-leeching line | The support's damage condition moved to full Energy Shield |
These are input changes, not complete build verdicts. A skill can receive a large numeric buff and still depend on weapon quality, defenses, map modifiers, and the surrounding passive tree.
💡 Build check: update the gem and passive values first, then recalculate the whole character. A percentage in patch notes is not the same as total build DPS.
Players returning to the game can compare current PoE build options before copying a setup that depended on 3.27 Grafts, Bloodlines, or gem values.
Ascendancy Changes and Player Impact
The Assassin received a substantial tree rework, including 100% increased Elusive effect on Mistwalker, removed old nodes, and new branches. Other classes received narrower changes that still altered established defensive and offensive calculations. The table pairs each verified change with its player-facing consequence.
| Class or node | Verified 3.27 change | Player-facing consequence |
|---|---|---|
| Heartstopper | Alternated every 10 seconds: 50% less damage from hits for 5 seconds, then 50% less damage over time for 5 seconds | Each mitigation mode covered only half of the 10-second cycle |
| Soul Drinker | Lost 20% increased attack and cast speed while leeching Energy Shield | Its leech identity remained, but its speed line did not |
| Spellbreaker | Lost +20% chance to suppress spell damage; prevented suppressed damage while on full Energy Shield rose from 10% to 15% | The node traded suppression chance for a stronger full-Energy-Shield effect |
| One Step Ahead | Both action-speed bounds changed to 90% | The old 108% self floor and 92% enemy ceiling no longer applied |
| Liege of the Primordial | Increased effect of Golem buffs fell from 100% to 50% | This was a direct reduction to the Elementalist node |
| Corpse Pact | Attack and cast speed per corpse consumed rose from 2% to 4%, still capped at 200% | The Necromancer reached the cap with fewer consumed corpses |
| Lesson of the Seasons | Prevented suppressed spell damage per missing Bark rose from +2% to +3% | This was a Warden Barkskin node, not a Juggernaut endurance-charge node |
Ascendancy edits need context from the rest of a character. The global Spell Suppression reduction, for example, changed how Spellbreaker and Lesson of the Seasons were evaluated even before their individual lines were considered.
Atlas, League, and Item Changes
Patch 3.27 rotated the Atlas by returning 25 maps and removing 25 others. It also allowed Tier 17 maps to corrupt into eight-modifier versions in some cases. This is historical Atlas information: later patches reworked that tier into Nightmare maps, so a current farming plan needs current map and Atlas data.
Keepers also changed how Breach progression interacted with the Atlas. Breach clusters were removed from the Keepers Atlas tree. Blessings upgraded Breachstones but no longer upgraded Breach Unique items. Three new fragments opened Uber versions of the three Incarnation encounters, expanding the league's endgame boss progression.
Harvest reforges began respecting restrictions such as Cannot Roll Attack Mods. For crafting, this is more than wording: a metamod could constrain the eligible outcomes of a reforge. Players should still test a current craft against current modifier tags and costs before committing an expensive item.
Foulborn Orb of Augmentation, Foulborn Regal Orb, and Foulborn Exalted Orb made higher-level modifiers more likely. They did not guarantee a high-level modifier or a specific tier. The difference between weighted probability and a guarantee is critical when estimating the risk and expected cost of a craft.
Nebulis began scaling fire resistance as well as cold and lightning resistance above 75%. Its rate became 5% to 10% increased Elemental Damage for each 1% resistance above 75%, and it gained 60% to 120% increased implicit-modifier magnitude. These exact ranges belong to the 3.27 patch state and should not be substituted for a current item roll without checking the live item.
Finally, Runegraft of Recompense became Runegraft of Refraction. Those exact names matter when searching archived listings. Players comparing old listings can browse current PoE item options after confirming the live name and modifier.

FAQ
Is Keepers of the Flame still the current PoE league?
No. Keepers of the Flame was the 3.27 challenge league, launched on October 31, 2025. Patch 3.28 later made a revised version of its Keepers and Breach content part of the core game. The Genesis Tree remained, while Graftblood was renamed Hiveblood and Grafts stopped being available. Use the 3.27 details here to understand that patch or an archived build, not to rank current league builds or describe its economy and Atlas.
How did Grafts work in patch 3.27?
Grafts occupied dedicated character slots and could grant modifiers or skills. Players grew them through the Keepers league system and modified them with Implant currency rather than treating them like ordinary rare equipment. That made a Graft part of a build's league-specific setup. When Keepers moved to core in 3.28, Grafts could no longer be grown or obtained, so a 3.27 build that requires one cannot be copied exactly in the later game.
Did Bloodlines give characters extra Ascendancy points?
No. Bloodlines were secondary Ascendancy classes unlocked through specific endgame bosses, but their passives shared the character's normal Ascendancy-point pool. A character could combine a Bloodline with a regular Ascendancy, then decide which nodes deserved those limited points. The system expanded the number of possible combinations without giving every build a second full tree for free. Boss access also meant that an intended Bloodline setup might not be available at league start.
Could players sell items while offline in PoE 3.27?
Yes. After reaching Act 6, a player could recruit Faustus to manage Merchant's Tabs. Priced items in those tabs could be purchased without the seller being online for a manual trade. GGG also added an in-game Trade Market interface. The feature improved transaction completion, but sellers still had to choose items, set prices, and use the relevant trading inventory. It did not automatically price every item in a normal stash.
How much damage did Spell Suppression prevent in 3.27?
The default amount fell from 50% to 40% of suppressed spell damage. Chance to suppress and the amount prevented are separate values, so reaching 100% suppression chance did not restore the old 50% mitigation by itself. Some passives or Ascendancy nodes could modify the prevented amount under their own conditions. Historical build guides need both values checked because copying only the chance can overstate the character's effective defense.
Was Heartstopper active for ten seconds at a time?
Heartstopper used a ten-second alternating cycle, but each defensive mode lasted five seconds. It gave 50% less damage taken from hits for five seconds, then 50% less damage taken over time for five seconds. Treating one mode as lasting the whole ten seconds changes how reliable the defense appears. A build still needed defenses for the damage type not covered by the active half of the cycle.
Did Foulborn Orbs guarantee a high-tier modifier?
No. The Foulborn Augmentation, Regal, and Exalted Orbs made higher-level modifiers more likely. A weighting advantage does not guarantee a high modifier tier or select a desired modifier group. Crafting cost therefore remained probabilistic. Before attempting a similar craft now, confirm that the currency still exists in the relevant form, inspect the current modifier pool, and calculate outcomes from live weights rather than a 3.27 summary.
Which skill buffs were easiest to verify?
Chain Hook of Trarthus gained up to eight initial targets, sixteen maximum chains, and 25% more damage. Cyclone, Cyclone of Tumult, and Vaal Cyclone dealt 20% more damage. Bladefall's base critical chance rose from 6% to 10%, while Dark Pact rose from 5% to 7% and increased its Skeleton-life sacrifice. Those are clear gem-level changes, but none proves that the skill became a top build without the rest of the character and encounter context.
