Grinding Gear Games has revealed the main details of Path of Exile 2 Patch 0.5.3. According to game director Jonathan Rogers, the goal of this update is to improve several endgame mechanics so that investing in them feels worthwhile regardless of the type of content players enjoy most.
Following the changes introduced in Patch 0.5.0, including new questlines designed to introduce players to each endgame league, the team identified opportunities to further improve some of these systems after players completed those quests. The result is a series of changes focused on rewards, progression, and fixing mechanics that were not working as intended.

Abyss Changes in Path of Exile 2 Patch 0.5.3
Abyss is receiving several changes aimed at improving both rewards and overall consistency.
Vessel of Kulemak and Grip of Kulemak
The unique ring Grip of Kulemak has received a complete review of its available modifiers.
According to Jonathan Rogers, some lesser-used modifiers have been removed, new modifiers have been added, and many existing effects have been merged together.
In addition, players who defeat the Vessel of Kulemak at full strength will now always receive an Ancient Desecration currency item.
The team also stated that they plan to add more unique items to this boss in the future.
Abyssal Depths Improvements
A bug that occasionally caused Abyssal Rare monsters to be missing from Abyssal Depths has been fixed.
Another important change is that the final large Abyssal Trove in Abyssal Depths will now always drop Desecrated Currency.
According to the developers, the combination of these changes should make Abyss feel significantly more rewarding.
Breach Improvements for Hive Fortresses
Patch 0.5.3 also introduces several improvements to Breach Hive Fortresses.
Larger Breach Biomes
Breach biomes are now significantly larger, allowing players to encounter more Hives for each Breachstone used.
Improved Benefits from Multiple Breachstones
The modifiers gained from using multiple Breachstones have been improved.
Some of these modifiers add new abilities to Ailith during Hive Fortress encounters. One example shown was the Nemesis modifier, which spawns Rare Monsters.
More Breach Improvements Coming in 0.5.4
Jonathan Rogers also confirmed that Patch 0.5.4 will include additional improvements for Breach, including more Ailith abilities and updates to Breach Tablets designed to better enhance Hive Fortresses.
Delirium Receives Major Fixes
Delirium is one of the main focuses of Patch 0.5.3.
According to the development team, several mechanics were not functioning as originally intended.
Purple Mirror Shards Fixed
A bug has been fixed that prevented monsters spawned from special Delirium Bar shards from appearing as Magic or Rare monsters.
This issue also affected Purple Mirror Shards, which were originally designed to spawn highly rewarding Elite Monsters.
With this fix, these monsters can now appear at higher rarities and provide rewards that better match the challenge they present.
More Elite Monsters from Multiple Purple Mirror Shards
Another issue involved using multiple Purple Mirror Shards.
Previously, activating several shards did not increase the number of Elite Monsters that appeared. This has now been corrected and will add significantly more Elite Monsters to maps.
Grand Mirror Fixes
The team also fixed an issue affecting maps opened between 150% and 200% Deliriousness through Grand Mirrors.
In these situations, Delirium monsters and Mirror Shards were not spawning correctly.
Difficulty Scaling Adjustments
Because these fixes result in significantly more monsters appearing, Delirium becomes more challenging overall.
To compensate, all Delirium scaling applied to monsters has been reduced by half.
However, each Delirium Tablet after the first now adds additional scaling back to monsters. According to Jonathan Rogers, using three Delirium Tablets results in the same scaling level as before.
Better Endgame Progression
According to the developers, these changes result in a Delirium experience with better combat, better rewards, and more options for scaling both difficulty and rewards in the late endgame.
Simulacrum Reworked
Simulacrum has also received several important changes.
Deliriousness Now Starts at 100%
Previously, Simulacrums started at 0% Deliriousness.
They now begin at 100% and gradually increase to 200% throughout the run.
Old Wave Modifiers Removed
The previous wave modifiers have been removed.
According to Jonathan Rogers, they increased difficulty but did not make the content more rewarding.
New Player Choice System
After completing each boss room, players can now optionally choose between three Mirror Shards.
The available choices include:
Adding bosses to all future rooms.
Adding modifiers that make the area harder and more rewarding.
Adding more monsters, including Elite Monsters.
Players may also choose not to select any of the available options.
Grand Expedition Improvements
Grand Expeditions are receiving a wide range of improvements as well.
According to Jonathan Rogers, highly optimized players were able to generate strong rewards from this content, but the average player experience was not as rewarding.
More Valuable Chests
The chests found in Grand Expeditions have been significantly improved.
The update increases the availability of chests that provide more valuable rewards.
Improved Weapon and Armour Chests
Weapon and Armour Chests now use golden icons.
These chests are rarer but now guarantee Exceptional Base types.
Better Monster Rewards
Each Rune passed on by Remnants now provides significantly larger Rarity bonuses to monsters.
More Remnants Available
The number of Remnants found within Grand Expeditions has also been increased.
Fewer Explosives Required
The number of explosives used during Grand Expeditions has been reduced by 25%.
According to the developers, this should reduce the overall time required to complete encounters while improving rewards.
Changes to Runeforged Armours
Patch 0.5.3 also includes adjustments to Runeforged Armours used in the endgame.
According to Jonathan Rogers, many players avoided this system because it required sacrificing too much Armour, Evasion, and Energy Shield.
To address this issue, the update reduces the amount of these defenses lost when applying Runeforging to endgame armour pieces.
Temple Receives a New Atlas Passive
Temple content is also receiving a significant update.
Previous Atlas Passive Replaced
Previously, an Atlas Passive allowed Temple rewards to appear in ordinary areas.
According to Jonathan Rogers, while powerful, this reduced the importance of the Temple-building mechanic itself.
As a result, the node has been replaced.
New Vaal Beacon Effect
After allocating the new node, activating a Vaal Beacon will corrupt a Rare or Unique enemy within the area.
This corruption can lead to a variety of outcomes.
The enemy may gain additional modifiers, become significantly more dangerous, or receive valuable reward enhancements.
According to the developers, the mechanic is designed to lean more heavily into the themes of corruption and risk associated with the Vaal.
