Path of Exile 2: Expedition Guide – Passives, Artifacts, & Rewards

Mastering Path of Exile 2's Expeditions: A Comprehensive Guide

Path of Exile 2 introduces four significant endgame events: Delirium, Breaches, Rituals, and Expeditions. This guide focuses on Expeditions, a returning mechanic from the original game, detailing its mechanics, rewards, and the strategic use of its passive skill tree.

Locating and Initiating an Expedition

Expeditions are identified on the Atlas screen by a light blue, spiral-shaped icon on map nodes. Guarantee an Expedition encounter by placing an Expedition Precursor Tablet into a completed Lost Tower slot.

Once in a map containing an Expedition, locate the marked area and interact with one of four NPCs. While they offer basic instructions, mastering the event requires understanding its core mechanics.

The central Detonator and the Explosives UI (bottom-right) are key. Your objective is to strategically deploy Explosives to trigger Runic Monsters, Unearthed Remnants, and Excavated Chests.

• Runic Monsters: Detonating Explosives near Red Markers spawns these. Larger markers yield larger monster packs, empowered further by Unearthed Remnants.
• Unearthed Remnants: These relics provide beneficial or detrimental modifiers (e.g., increased elemental damage but higher item rarity from chests).
• Excavated Chests: Located near Black Markers with the spiral symbol, these chests contain valuable rewards: Artifacts, Logbooks, currencies, Waystones, and high-tier gear.

Explosives' area of effect (AoE) is crucial. Avoid overlapping AoE circles for optimal farming. Place all Explosives, then activate the Detonator to initiate the event. Death resets the map, but you can strategically retreat and return later.

The Expedition Pinnacle Map

Runic Monsters and Excavated Chests have a chance to drop Expedition Logbooks. These are used with Dannig in your hideout to access the Expedition Pinnacle Map – a significantly larger Expedition event with triple the Explosives.

This map system introduces Olroth, a Pinnacle Boss. His spawn chance increases with map level, indicated by a skull on the minimap. Defeating Olroth is vital for earning Expedition Passive Skill Tree points (2x points per victory).

Expedition Passive Skill Tree

Accessible via the Atlas Passive Skill Tree, the Expedition Passive Skill Tree enhances the event. It's located in the top-right of the Atlas Skill Tree menu, distinguished by its spiraling blue design.

The tree features eight Notable nodes and eight nodes increasing Logbook difficulty (and Olroth's challenge). Each Notable node requires defeating Olroth at an increased difficulty.

Prioritize "Disturbed Rest," "Detailed Records," and "Timed Detonations" for significant reward increases. Then consider "Weight of History," "Unearthed Anomalies," and "Legendary Battles" for further, albeit more challenging, rewards. Avoid "Extreme Archaeology" due to the significant reduction in Explosives.

Expedition Rewards

Artifacts are the primary rewards, each used with a specific vendor:

Remember, you only access one vendor per Expedition, but Artifacts remain after map completion. Exotic Coinage refreshes vendor inventories. Expedition Logbooks unlock the Pinnacle Map and a chance to encounter Olroth, yielding exceptional rewards and additional passive skill points.
