Grinding Gear Games revealed the 0.5 Return of the Ancients update for Path of Exile 2 yesterday, and this isn’t going to just be an update; it’s a reinvention. The entire endgame has been reworked, every major mechanic has been overhauled or restructured, there’s a new challenge league with its own crafting system, two new Ascendancies, a completely rebuilt Atlas Passive Tree, and over 100 new crafting currencies. Patch 0.5 launches May 29 at 1 PM PDT on PC and consoles simultaneously.

If you bounced off Path of Exile 2’s endgame because it felt aimless or directionless, this update is specifically targeting that problem. Check out the trailer below, and the full reveal a little further down if you missed it yesterday.

Runes of Aldur Challenge League

Runes of Aldur is Path of Exile 2’s next challenge league, which means a fresh economy and a clean start for everyone. The league mechanic centers on Ezomyte Remnants guarded by monsters. Kill the monsters, choose your reward, and the monsters resurrect empowered with buffs tied to your selection. Kill them again to claim the loot. The number of Rune slots scales with area level, so higher level content means denser encounters with more reward options.

Every Rune combination you discover gets permanently recorded in your Runebook and stays available for future encounters. That’s a smart long-term hook that rewards experimentation without punishing you for trying something that doesn’t work.

The league also introduces Runeforging, a new crafting mechanic. Different crafting materials enhance Rares or Uniques in specific ways. One example is Verisium, which adds Runic Ward to your armor’s implicit modifier. Runic Ward functions as an extra life pool that activates after your health drops to 1, giving you a window to recover. Other Runeforging outcomes include replacing defensive modifiers for a massive chunk of Runic Ward, adding entirely new modifiers to existing Uniques, and upgrading low-level Uniques to deal significantly more damage.

New Skill and Support Gems are being added that consume Runic Ward instead of Mana and have no attribute or weapon requirements, meaning they work on any class. Over 100 new Runes and crafting currencies round out the league’s additions. Complete 8 tasks during the league to unlock a full microtransaction armor set.

Endgame Overhaul

The endgame has been restructured around five new Questlines that each come with their own dedicated area, crafting choices, and bosses. The starting area now has clear, streamlined quests designed to eliminate the “what am I supposed to do now” feeling that hit a lot of players when they first reached the Atlas.

The biggest new addition is Fortresses. Complete the first Tower and a massive Fortress erupts on your Atlas. Areas inside the Fortress walls get special enhancements: all Rares become Essences, monsters get packed into Strongboxes, Azmeri Spirits that don’t disappear, and more. Fight your way to the center to face the new Pinnacle Boss. Defeating the boss reveals new Fortress sections, and Map Bosses within those walls grant Atlas Passive Points. Clearing a section auto-completes unfinished maps within it, which dramatically speeds up Atlas progression.

Atlas Passive Tree and Masters

The Atlas Passive Tree has been completely rebuilt and is significantly larger than before. Every node can eventually be allocated, but choices still matter because many nodes have multiple options to pick from. The goal is to stop players from feeling like they need to constantly respec their Atlas depending on what maps they encounter.

Three new Atlas Masters have been added, each granting an extra Skill Tree for your endgame maps. Only one Master can be active at a time, but you can freely swap between them for each map. Jado’s Spycraft focuses on investigation and can drop more Rares, more Uniques, or add extra modifiers to corrupted Waystones. Hilda’s Hunting revolves around assassinating marked Unique Monsters and grants boss-focused bonuses. Doryani’s Science rounds out the trio with its own specialization.

Mechanic Reworks

Every major endgame mechanic has been reworked and restructured into its own Questline. Expedition now reveals island groups on the Atlas with varied encounter types and chained boss fights, culminating in a hidden powerful boss. Abyss features large connected encounters across multiple maps with faction bosses leading to the Kulemak fight. Delirium gets a reworked progress bar with visible encounter icons, Strange Fruit items that create chains of increasingly delirious maps ending in the Simulacrum, and new Liquid Emotions that add specific craftable modifiers to Jewels. Breach introduces a Hiveblood and Wombgift system with a full crafting tree for incubating items with specific modifiers and base types. Ritual now features Wildwood encounters with a chain of five maps where captured monsters carry over between maps, making each successive encounter harder.

Each mechanic is introduced through a dedicated Questline before it appears randomly on your Atlas, so you learn how it works before it starts showing up everywhere.

Two New Ascendancies

Spirit Walker for the Huntress revolves around three animal spirits (stag, bear, owl), each with different trigger conditions and effects. Specialize in one or allocate all three to unlock Sacred Unity, which enhances all animal effects simultaneously. The standout node is “The Natural Order,” which lets you use Tame Beast on Unique Beasts, including the Chimera from Act 3.

Martial Artist for the Monk channels to create mirages that use his skills, spawns Bells, puts a Bell on his back, sockets additional Runes, and augments Glove stats. The Monk really likes bells.

Quality of Life

The update also adds a search box on the Atlas screen that highlights maps as you type, an in-game Build Planner, and native item price checking. Campaign layouts now include visual tells to guide navigation, like trails of locusts pointing toward area entrances and bloody footsteps leading to bosses. The Arbiter now has its own Questline and Fragments are far easier to find.

The Big Picture

This is the kind of update that separates Path of Exile from everything else in the ARPG space. The scope of what Grinding Gear is doing with a single patch would be a full expansion for most other games. Five reworked endgame mechanics, each with their own questline and boss encounters. A complete Atlas Tree rebuild. A challenge league with its own crafting economy. Two Ascendancies. An in-game build planner. This is a staggering amount of content for a game that’s still technically in Early Access.
