Grinding Gear Games unveiled the upcoming Path of Exile 2 patch 0.5, titled "Return of the Ancients," which includes nearly 900 words of updates. The patch features a comprehensive redesign of the endgame, introducing new systems like Atlas Ascendancies and league-specific features such as Runes of Aldur. The Runes of Aldur league involves rescuing a blacksmith and activating remnants for rewards, including over 100 new runes and a new stat called Runic Ward. A new currency type, Alloys, allows crafting modifiers on items. The endgame has a revamped structure with fixed league mechanics and unique quest lines, culminating in encounters with the Arbiter of Ash and a mysterious ultimate boss. All four launch mechanics have received upgrades, and quality-of-life improvements include in-game build guides and enhanced market features. Two new Ascendancies, the Spirit Walker Huntress and Martial Artist Monk, will be introduced, along with new unique items like Raven's Flock. The patch is scheduled for release on May 29, 2026, with a showcase at Exilecon in November.
