Complete Guide to Expedition Farming in Path of Exile 2: Crafting, Loot, and Bosses

Expedition Farming Guide

This guide covers the basics of farming Expedition in Path of Exile 2, including its rewards and how to challenge the pinnacle encounter by completing Expedition Logbooks. It also includes recommendations for the best Atlas Passive Nodes to optimize currency generation.

How it Works

While completing Maps on your Atlas, you may encounter maps with the Expedition mechanic. Generate valuable loot by placing explosives at dig sites and killing the monsters that are unearthed. Use the special currency gathered to craft items at Rog, Gwennen, Tujen, and Dannig. Not interested in crafting? You can sell the items to other players in the Currency Exchange.

Here are your goals when completing an Expedition:

1. Unearth as many Runic Monsters as possible, indicated by the large flagpoles scattered across the digsite.
2. Logbook Drop Chance, Remnant Modifiers, and Detailed Records only apply to Runic Monsters, so prioritize Runic Monster spawns.
3. Empower Runic Monsters by blowing up Unearthed Remnants along the path; each one grants both an upside and a downside to the monsters you unearth afterward.
4. Always pick up modifiers that increase Rare monster spawns and Logbook Quantity.
5. Prioritize these first, if possible, as they do not work retroactively: Runic Monsters unearthed before the Remnant does not gain the Remnant bonuses later in the detonation chain!
6. In general, prioritize as follows: Runic Monsters duplicated → Quantity of Logbooks → Increased number of Rares → Quantity of Items dropped → Rarity of Items dropped.
7. Reveal Excavated Chests by blowing up signs with the Expedition icon on them.
8. Icons indicate normal, magic, and rare chests.
9. Don't prioritize these heavily, but try to pick them up along the way when it's convenient.
10. Chests can drop Expedition Logbooks.

A Common Mistake: Prioritizing Low-Value Remnants Over Flagpoles That Spawn Runic Monsters

Remnants mainly serve to increase the loot from Runic Monsters. Simply rushing to collect as many Remnants as possible is like running a Waystone that has 1000% increased Item Rarity but no monsters in it!

"Example of an Expedition"

Click the UI element (or assign a hotkey in your settings) to the left of your Skillbar to place your Explosives. The number next to it shows how many explosives you can still place.

• Create a fuse line that sequentially detonates.
• Unearth Remnants, Runic Monsters, and Chests within the green circle around your cursor.

Be Careful: Yellow Remnant Modifiers can potentially make the Expedition impossible for your build. Skip any mods you can't handle!

• Undo placing an Explosive by clicking the back arrow in the UI if you're not satisfied with the placement.
• Click the Detonator (usually located in the center of the Expedition area and next to the NPC) to begin the Encounter.
• Defeat all the monsters that are unearthed.
• Expedition monsters can be very dangerous, so be cautious and don’t get overconfident!

Tip: If your build excels against large packs of monsters (e.g., Herald of Ice builds), you can walk away and wait for all the monsters to be unearthed before clearing them in one go.

• Click all the Excavated Chests and loot the area.

The Rewards

The exclusive rewards from Expedition include: Black Scythe Artifacts, Broken Circle Artifacts, Order Artifacts, Sun Artifacts, Exotic Coinage, and Expedition Logbooks.

Expedition also generates a significant amount of Waystones and regular Currency by spawning many additional mobs in your maps.

How to Run

"Look for a map with the Expedition icon to find Expedition encounters!"

Maps have a chance to naturally contain an Expedition encounter, as indicated by the icon shown above.

Use an Expedition Precursor Tablet on a Watchtower to guarantee an Expedition encounter in nearby maps. This will add an Expedition encounter to the number of maps specified by the implicit modifier of the item. Any explicit modifiers will apply to all uncompleted maps within the tower's radius.

Pinnacle Encounter

"Logbook UI"

Bring your dropped Expedition Logbooks to Dannig and select "Show Expedition Map" to run them. Logbooks are essentially one large Expedition and grant a significant amount of loot. Alternatively, you can sell them to other players.

Expedition, like all Atlas Mechanics in Path of Exile 2's early access, has a Pinnacle Boss encounter. Defeat Olroth inside a Logbook to earn Expedition Atlas Passive Points. Olroth requires a Logbook with an Area Level of 79 or higher to have a 20% chance of spawning. Once inside the Expedition, check your Minimap for a Skull Icon, which marks Olroth's position. Path your explosives toward the skull until you trigger the Boss Encounter marker. This will allow you to descend into the Crypt to fight him.

"Skull Icon indicating Olroth's position"

Abilities

Olroth has 2 phases and a combination of basic attacks, dashes, and the following special attacks:

Sword Slam

Olroth lifts his sword into the air and slams it into the ground, creating an area of pulsing aftershocks.

Boomerang Attack

Olroth throws his weapon, which returns shortly after. Upon catching it, he casts a cold damage AoE around himself. The AoE has no telegraph, so be sure to keep your distance when he throws his weapon.

Carousel Degen

Olroth summons rotating pillars that deal damage over time.

Charge Stab

Olroth charges up a damaging dash while standing still. His weapon glows during the charge. He then sweeps his sword from right to left at the end of the dash, so maintain a medium distance from him.

Arena Hazards

In Phase 2, a star-shaped pattern constantly circles the Arena. It shoots 3 different hazards that should be avoided:

• A tracking cold beam that slowly follows you.
• Cold projectiles that target your current position and explode in a small area.
• A massive beam that cuts through the center of the Arena and leaves Chilled Ground afterwards.

Atlas Passives

Timed Detonations

Increases the number of Artifacts and speeds up detonations.

Legendary Battles

Increases the number of Rare monsters and Exotic Coinage.

Frail Treasures

Grants additional Chest Markers. Loot the chests quickly, as they despawn after 5 seconds.

Weight of History

Remnants empower nearby monsters more.

Unearthed Anomalies

Remnants drop more loot but make the monsters harder to kill.

Extreme Archaeology

Greatly speeds up placing Explosives but reduces control over which mods to select.

Disturbed Rest

Increases the number of Runic Monster Markers. Makes Expeditions harder but more rewarding.

Detailed Records

Increases the frequency of Logbook drops and adds special implicit modifiers.

Recommended Atlas Nodes

"Expedition Atlas Tree + Logbook Atlas Tree to raise your Logbook Area Level"

Allocate the following nodes in order of importance:

Disturbed Rest

More Runic Monsters mean more loot. Simple.

Detailed Records

Increases the frequency and quality of Logbooks.

Timed Detonations

Provides more Expedition-specific currency and speeds up the Encounter.

Legendary Battles

Increases the number of Rare monsters for more generic loot, Logbooks, and a boost to Exotic Coinage drops.

You can use the Logbook Atlas Tree to raise your Logbook Area level to 79+ to spawn Olroth, even if the area level of your Logbooks is lower.

Expedition Crafting

Black Scythe Artifacts, Broken Circle Artifacts, and Order Artifacts allow you to craft gear by talking to Rog (for Armor), Gwennen (for Weapons), and Tujen (for Jewelry). Exotic Coinage lets you reroll their offerings. Use Sun Artifacts with Dannig to convert them into another type of your choosing.

"Crafting Base Selection"

Here you can pick any promising base to begin your craft. Can't find anything good? Use Exotic Coinage to reroll the Vendor's selection. The item level (ilvl) of the bases increases based on your own Character's level upon rerolling, scaling up to ilvl 80 at Character level 90.

The crafting process is straightforward. You have 3 available options:

Upgrade your item with the given changes for an upgrade price.
Affected mods are highlighted in Orange.
Potentially affected mods are highlighted in Yellow, meaning it may pick one or the other, but not both.
Options may target: All prefix or suffix modifiers, Modifiers of the highest or lowest tier, or pick a single modifier at random.

Reroll Modifiers: Removes all highlighted modifiers and adds an equivalent amount of new modifiers to the item.

Reroll Modifier Values: Changes the numeric values of the specified modifiers within its tier. Equivalent to the effect of a (targeted) Divine Orb.

Add Modifier: Adds a modifier to your item. Equivalent to the effect of a (targeted) Exalted Orb.

Remove Modifier: Removes a modifier from your item. Equivalent to the effect of a (targeted) Orb of Annulment.

Skip the current Upgrade if the effect is not desirable.
You cannot skip two consecutive crafts.
Skipping causes the cost of the next craft to be 50% higher.
Take your item when you run out of good options or if the item is no longer worth crafting.
