Path of Exile 2 (PoE2) builds upon the immense success of its predecessor, enhancing both gameplay mechanics and visual fidelity. One of the POE 2 Currency most engaging aspects returning from the original game is the Expedition League mechanic, reworked and reintegrated into the sequel with a fresh layer of complexity and reward potential. In this guide, we’ll explore everything you need to know about the Expedition mechanic in Path of Exile 2, including how to optimize your use of passives, farm artifacts, and claim valuable rewards.

What is the Expedition Mechanic?
Expedition is a league mechanic in which players assist the Kalguuran expeditionary force in uncovering and battling ancient remnants buried beneath Wraeclast’s surface. Each Expedition encounter allows you to place explosives in specific patterns to unearth relics, spawn monsters, and modify the battlefield. These encounters are not only thrilling but highly rewarding, providing opportunities for massive loot hauls, valuable currency, and access to specialized vendors.

In PoE2, Expedition encounters can occur in both the campaign and endgame maps. The challenge and complexity increase with your progression, but so do the rewards.

How Explosives Work
Before diving into passives and rewards, it's important to understand the foundation of Expedition: explosives. When you encounter an Expedition site, you’ll be given a limited number of explosives. Your goal is to strategically place them to maximize your yield.

Each explosive detonates a portion of the buried area, and any remnants caught in the blast provide modifiers. These modifiers can boost the number of monsters, increase difficulty, or add reward types (such as currency, artifacts, or logbooks). Carefully chaining remnants together allows you to stack multipliers—creating both more challenging encounters and exponentially better rewards.

Planning your detonation path is essential. Look for remnants that synergize—for example, “Monsters drop additional currency” alongside “Monsters have 40% more life” creates a lucrative yet manageable fight if your build can handle the increased toughness.

Kalguuran NPCs and Vendors
After completing an Expedition, you'll often encounter Kalguuran merchants. Each vendor has a unique trading mechanic tied to specific types of artifacts. There are four types of artifacts used as currency:

Black Scythe Artifacts

Knights of the Sun Artifacts

Order of the Chalice Artifacts

Druids of the Broken Circle Artifacts

Each artifact corresponds to a faction and is used to trade with their associated merchant:

Tujen the Haggler: Offers rare items, haggling with a unique risk/reward system.

Rog the Dealer: Helps you craft and upgrade gear, with a focus on customizing items step-by-step.

Dannig, Warrior Skald: Exchanges artifacts for Expedition Logbooks and can open portals to special zones.

Gwennen the Gambler: Lets you gamble on unidentified gear, similar to a mystery box system.

Logbooks in particular are a key component of Expedition endgame. These items open up entire maps filled with Expedition encounters, allowing players to select specific modifiers and paths—offering massive rewards for those who can navigate them effectively.

Passive Skill Tree Synergy
In PoE2, the revamped passive skill tree includes even more opportunities to specialize in league mechanics like Expedition. While the exact tree layouts may differ depending on your class and ascendancy, look for nodes that enhance reward types, increase the number of remnants, or improve explosive range.

Additionally, in the endgame Atlas passive tree, players can allocate points to enhance specific mechanics in maps. Focusing on Expedition-related nodes can lead to more frequent encounters, higher drop chances for logbooks, and more powerful remnant effects.

Best Rewards to Target
Some of the most valuable Expedition rewards include:

Ancient Orbs (rare currency that can reforge unique items)

Logbooks (for farming special expedition zones)

High-end base items (via Rog and Gwennen)

Divine Orbs, Exalted Orbs, and other high-tier currencies from mod-stacked remnants

Players aiming to maximize profit should plan detonations to prioritize remnants that enhance item rarity and quantity or increase the number of runic monsters.

Final Tips
Always inspect remnant modifiers before detonating. Some combinations can make encounters deadly.

Use Gwennen sparingly unless you’re targeting specific uniques. Her returns are luck-based.

Save logbooks for farming sessions, and consider selling high-roll ones to other players.

Use the Atlas passive tree to scale Expedition chances in favored maps.

Whether you're diving into Expedition for profit, fun, or character progression, it remains one of Path of Exile 2's richest mechanics. With strategic planning, knowledge of the Kalguuran factions, and smart use of your passives, you can turn every Expedition into a cheap POE 2 Currency treasure hunt worthy of legends.
