Grinding Gear Games has been stacking skill trees in Path of Exile 2 like most developers stack patch notes, and the 0.5.4 update is the latest proof of that philosophy. Dropped this week, the patch adds a brand new Atlas Passive Tree tied to the Runes of Aldur league, alongside a meaningful quality-of-life change that makes unique items far more accessible earlier in a playthrough.
A new tree built around Expeditions
The Atlas Passive Tree added in 0.5.4 contains 24 nodes, all of them oriented around the Expedition Encounters that sit at the heart of the Runes of Aldur league. That focus makes sense given how central Expeditions are to the current season's loop, and the nodes reflect that with a mix of passive buffs and active mechanical choices.
Here's the thing: not every node does the same kind of thing. Some increase the frequency of Expedition Encounters you trigger in a map. Others let you find additional Remnants, which shifts how you approach the layout of each encounter. Game director Jonathan Rogers walked through several examples in a developer overview, including one where a new merchant named Farrow starts selling a fresh currency type depending on which nodes you've invested in. The variability is deliberate, and very on-brand for Grinding Gear Games.
The tree is designed so players can lean into either passive stat bonuses or more active playstyle shifts. You'll want to think about what your current build actually needs before spending those nodes, because the choices pull in genuinely different directions.
Unique items no longer locked behind late-game requirements
The more broadly impactful change in 0.5.4 is how unique items now handle level scaling. Uniques that grant new skills will now tone down their power if your character hasn't hit the expected level threshold yet, rather than simply being unusable. Rogers called it a "real shame" that these items were effectively gatekept from lower-level characters, and the fix is straightforward: the game now scales them down to meet you where you are.
The direct quote from Rogers sums it up well: "This should open up a whole bunch of builds available to play much earlier."
That's not a small thing for a game where build diversity is a core part of the appeal. Players who previously had to wait until the endgame to experiment with certain skill-granting uniques can now start testing those combinations from much earlier in a run. For anyone who has spent time with our PoE 2 Patch 0.5 Return of the Ancients complete guide, this change slots naturally into the broader effort to make the game's progression feel less punishing.
New Orbs of Sacrifice and what they actually do
Patch 0.5.4 also introduces several new Orbs of Sacrifice, which work by trading a randomly selected modifier from an attached item in exchange for a stacked corruption. You earn them by defeating Atrizi, which is its own challenge. The mechanic leans heavily into chaos, since the modifier that gets pulled is random, making the outcome unpredictable.
This is the kind of system that will appeal to players who enjoy gambling with their gear, and frustrate everyone else. The tradeoff is real: you might strip a modifier you wanted to keep, or land a corruption that dramatically improves the item. It's high-variance by design.
What comes after 0.5.4
Rogers confirmed that 0.5.4 is the last major patch "for a while," with the next update expected to bring further changes to the game's systems. Given the pace of additions throughout the Runes of Aldur league, that next patch will have a lot to build on.
