PoE 2 Patch 0.5.3 Endgame Farming Guide: Abyss, Expedition, Delirium

Patch 0.5.3 dropped June 18, 2026, roughly two weeks into the Runes of Aldur league. It is not a content patch. It is a reward correction: the kind that happens when the developers watch their activity heatmaps and realize players are ignoring half the endgame because the return on investment is insulting. Path of Exile 2 endgame farming just got a meaningful overhaul across Expedition, Abyss, Delirium, Breach, and Ritual simultaneously.

The honest summary: several mechanics were bugged and not spawning the correct number of monsters or rewarding correctly. Fixing bugs that inflate farm value is, in practice, a buff: even if no numbers changed on paper. Keep that in mind when someone tells you a mechanic "got doubled."

This is the mechanic that received the most complete structural change. The developers removed all basic Weapon and Armour chests from Grand Expeditions: the ones that dropped gear you immediately sold to a vendor: and replaced them with chests that drop currency, unique items, Waystones, Mysterious Chests, and Trinket Chests. The chest pool is now worth interacting with.

Two other changes matter for your Atlas setup. The maximum number of Remnants now scales with Waystone tier, maxing out at Tier 15+. You can also now run Grand Expeditions with 15 explosives instead of 20, shortening the encounter while your decisions carry more weight. The PoE 2 Grand Expedition guide calculus for 0.5.3 is simple: run Tier 15, use an Irradiated Tablet to push effective Tier 16, and slot Jado's Spycraft to reroll Verisium Remnants for their rarest outcome.

Runic Modifier rewards on monsters granted by Runic Inscriptions have been roughly doubled in most cases, significantly more in some. This is the actual reason currency feels better, not the chest rework alone.

Runeforging: Finally Touch It

Before this patch, applying a Runic Word to a 1,800-armour chest could strip over 1,000 armour just to gain a minor runic bonus. Nobody did this. Now the defence penalty on high-level non-Unique armour bases is reduced by approximately 20%, while Runic Ward gained remains the same. Existing items update automatically. If you have been sitting on Runeforging materials because the tradeoff was stupid, the tradeoff is less stupid now.

Abyss and Vessel of Kulemak

Abyss got two targeted changes that turn it from a slot machine into something with a guaranteed income floor. The final Abyssal Trove at the end of a Depth now always drops Desecrated Currency. The Pinnacle Boss, Vessel of Kulemak, now always drops an Ancient Material for Desecration when defeated at full strength. An Ancient Collarbone converts to roughly three Divine Orbs at current prices. An Ancient Jawbone sits around two. These prices will drop as supply normalises: farm early if you intend to capitalise.

The Vessel of Kulemak ring also received a full rework. Weaker modifiers were removed and replaced. The choice system: where you select which boss's modifiers you want after the first kill: remains arcane and poorly explained, but the pool is now at least worth reading. You will still need a wiki tab open. The developer acknowledged the boss rewards are "a bit lackluster right now" and promised additional passes. Take that on faith.

A bug was fixed that prevented the correct number of Rare and Magic monsters from spawning in Abyssal Depths. This alone is functionally a significant buff to Depths farming, regardless of any explicit number changes.

Delirium and Simulacrum

Delirium got split into two distinct experiences. Early endgame maps: fog scaling difficulty was halved, making it far less punishing for builds that aren't fully geared. Late endgame: using three Delirium Tablets returns fog scaling to its previous value. The difficulty scales back up as you invest. This is a reasonable design decision that the game explained poorly for months.

Purple mirrors: previously ignored unless they were orange: now always spawn Elite Magic monsters instead of standard enemies. Those monsters drop notably better loot. The primary Delirium income is still Emotions, and the developers did not make Emotions drop more directly from Delirium mobs. They added more items instead. Whether that translates to more Divines on trade is a market question, not a design one.

Simulacrum Changes

The Simulacrum endgame farming loop changed in two meaningful ways. First, Simulacrum Maps no longer spawn immediately when spreading Delirium fog: they now spawn when you reach 100% Deliriousness in the fog bank. Second, and more importantly, Simulacrums now spawn Shards between waves, letting you pick one of three mid-run options:

• Escalating Threats: adds a modifier that increases danger and reward
• Apex Predators: adds an additional Boss to the encounter
• Pure Emotions: adds more monster packs

Circles of Power in the Simulacrum encounter now persist past the fog advance. You no longer need to sprint through them. This is a quality-of-life change that existed because of a bug, not intentional design. Enjoy the fix.

Breach Strongholds

Breach Strongholds are larger, Wombgift is consumed faster, and the modifier pool was reworked with three new named modifiers replacing weak options. If your build was already suited for Breach before this patch, nothing about your strategy changes except the rewards improved. If your build barely survived it, adding Breach juice does not fix that: the difficulty scaled alongside the rewards.

Breach remains one of the strongest mechanics for farming Dense packs efficiently. The Stronghold changes make prolonged Breach investment more appealing without demanding a full atlas respec to access the improvement.

Ritual: They Tried

Ritual received more Rare and Magic monster spawns per encounter, and Arie now has updated abilities that theoretically offer more options during the fight. In practice: you will not notice the ability changes if your build is functional, because you kill everything too fast for them to matter. The ability you actually used: spawning additional monsters: is now available in greater quantity. The rest are situationally useless.

The developers explicitly stated that deeper Ritual improvements are coming in patch 0.5.4, specifically around the Hive encounters. Current changes are a placeholder. Do not build an entire farming strategy around Ritual changes that are openly labeled as incomplete.

Vaal Temple: Still Suffering

The node that allowed Temple currency to drop outside of the Temple was removed because it was deemed imbalanced. It now rewards a Yellow monster. The practical result: if you want Temple currency, you go to the Temple. Ezekiel would be proud of this design philosophy.

The Vaal Temple farming meta remains unchanged from before: rush to Atziri for a guaranteed sellable drop, skip the elaborate room-optimisation planning that assumes you have more time than the drop rate justifies. The developers appear to have no current interest in making Temple more engaging. It broke the previous league, and they are not ready to forgive it.

What to Farm Right Now

One rule survives every patch: do not copy an advanced farming rotation without copying the build strength behind it. If someone is farming Simulacrum profitably, it is because their build handles 200% Delirious without dying six times per wave. The map strategy is the last 20%. The build is the first 80%.
