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

Path of Exile 2 introduces Expeditions, a revamped endgame system from the original game. This guide details Expedition mechanics, rewards, and the passive skill tree.

• Expedition Mechanics & Detonation
• Expedition Passive Skill Tree
• Expedition Rewards

Four major endgame events—Delirium, Breaches, Rituals, and Expeditions—await in PoE 2's Atlas. Expeditions, a returning league mechanic, offer unique challenges and rewards.

Expedition Mechanics & Detonation

Expedition map nodes on the Atlas are marked with a light blue spiral icon. Use an Expedition Precursor Tablet in a completed Lost Tower slot to guarantee an Expedition encounter.

Within the Expedition zone, locate the Markers and the tent containing one of 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: Relics granting 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.

Use the Explosives UI to visualize the area of effect. Avoid overlapping AoE circles for optimal farming. After placing Explosives, activate the Detonator. If overwhelmed, retreat and return later; the event persists.

Expedition Pinnacle Map

Runic Monsters and Excavated Chests have a chance to drop Expedition Logbooks. Use these Logbooks with Dannig in your hideout to access the Expedition Pinnacle Map—a significantly larger Expedition with triple the Explosives.

The Pinnacle Map features Olroth, a challenging boss (skull icon on minimap). Defeating Olroth awards 2x Expedition Passive Skill Tree points.

Expedition Passive Skill Tree

Located within the Atlas Passive Skill Tree, the Expedition tree enhances rewards and difficulty. Points are primarily obtained by defeating Olroth. Increasing Logbook difficulty is necessary to unlock new Notable nodes.

Prioritize "Disturbed Rest," "Detailed Records," "Timed Detonations," "Weight of History," "Unearthed Anomalies," and "Legendary Battles" for optimal rewards. Avoid "Extreme Archaeology" due to its significant reduction in Explosives.

Expedition Rewards

Artifacts are the primary currency. Four types exist, each used to trade with a specific vendor for unique gear. Exotic Coinage refreshes vendor inventories.

Expedition Logbooks unlock Pinnacle Maps, increasing the chance of encountering Olroth and obtaining high-tier rewards and unique items. Defeating Olroth is crucial for acquiring Expedition Passive Skill Tree points.
