PoE 2 Expedition: Uncover Passives, Artifacts, and Rewards

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 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. You can guarantee an Expedition encounter using an Expedition Precursor Tablet in a completed Lost Tower slot.

Within the Expedition zone, locate the central Detonator and four NPCs. The core gameplay involves strategically placing Explosives near Markers to trigger events:

• Red Markers: Detonating explosives near these spawns Runic Monsters. Larger markers yield larger monster packs, enhanced by Unearthed Remnants.
• Unearthed Remnants: These relics provide beneficial or detrimental modifiers (e.g., increased monster elemental damage for increased item rarity from chests).
• Black Markers (spiral symbol): Explosives near these spawn Excavated Chests containing Artifacts, Logbooks, currency, Waystones, and high-tier gear.

The Explosives UI shows the area of effect (AoE). For optimal farming, avoid overlapping AoE circles. After placing explosives, activate the Detonator. You can strategically leave the area after detonation and return later to engage enemies with AoE abilities. Death resets the map, but leaving the area doesn't end the event.

The Expedition Pinnacle Map and Olroth

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

This map has a chance to feature Olroth, the Pinnacle Boss (indicated by a skull on the minimap). Defeating Olroth is crucial for obtaining Expedition Passive Skill Tree points (2x points per victory).

Expedition Passive Skill Tree

Located within the Atlas Passive Skill Tree, the Expedition Passive Skill Tree enhances the Expedition event. Points are used to increase rewards, monster spawns, and Remnant effects. The tree features eight Notable nodes and eight difficulty-increasing nodes for Logbooks and Olroth. 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, more challenging improvements. Avoid "Extreme Archaeology" due to the significant reduction in Explosives.

Expedition Rewards

Artifacts are the primary rewards, each used to trade with a specific vendor for particular gear types:

Expedition Logbooks, obtained from Runic Monsters and Excavated Chests, unlock the Expedition Pinnacle Map system, offering a chance to fight Olroth for high-tier rewards and additional Passive Skill Tree points. The higher the Logbook difficulty, the greater the chance of Olroth appearing and dropping better loot.
