Mastering Path of Exile 2's Expedition Endgame: A Comprehensive Guide

Path of Exile 2 introduces four major 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 crucial Expedition Passive Skill Tree.

Understanding Expeditions and the Detonation Mechanic

Expedition map nodes on the Atlas are marked with a distinctive light blue spiral icon. An Expedition Precursor Tablet placed in a completed Lost Tower slot guarantees an Expedition encounter.

Entering an Expedition reveals a zone with Markers and a tent housing four NPCs. The core mechanic involves strategically placing Explosives near Markers to trigger events:

• Runic Monsters: Detonating Explosives near Red Markers spawns monster packs, enhanced by Unearthed Remnants. Larger Markers yield larger packs.
• 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 Artifacts, Logbooks, currency, Waystones, and high-tier gear.

The Explosives UI shows the area of effect (AoE). Maximize rewards by ensuring AoE circles don't overlap. After placing Explosives, activate the Detonator. If overwhelmed, retreat and return later; the event doesn't end upon leaving.

The Expedition Pinnacle Map

Runic Monsters and Excavated Chests have a chance to drop Expedition Logbooks. Dannig in your Hideout opens the Expedition Map for a Logbook. Slot the Logbook and click "Open Portals" to access a significantly larger Expedition event with more Explosives.

This Pinnacle Map features Olroth, a challenging boss (skull icon on minimap). Defeating Olroth grants 2x Expedition Passive Skill Tree points. The higher the map level, the greater the chance of Olroth appearing.

Expedition Passive Skill Tree

Located within the Atlas Passive Skill Tree, the Expedition Passive Skill Tree enhances the event. Points are earned by defeating Olroth. The tree features Notable nodes and difficulty-increasing nodes for Logbooks.

Prioritize "Disturbed Rest," "Detailed Records," and "Timed Detonations" for significant reward boosts. Then consider "Weight of History," "Unearthed Anomalies," and "Legendary Battles" for increased difficulty and rewards. Avoid "Extreme Archaeology" due to the drastic reduction in Explosives.

Expedition Rewards: Artifacts and Coinage

The primary rewards are Artifacts, used to trade with Expedition vendors for specific gear types:

Each Expedition features one vendor. Artifacts aren't consumed after map completion. Exotic Coinage refreshes vendor stock. Expedition Logbooks unlock Pinnacle Maps, increasing the chance of encountering Olroth and obtaining high-tier rewards and unique items.
