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

Mastering Path of Exile 2's Expedition Endgame: 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 Path of Exile, detailing its mechanics, rewards, and optimal strategies.

Locating and Initiating an Expedition

Expeditions are identified on the Atlas screen by a light blue, spiral-shaped icon on map nodes. An Expedition Precursor Tablet placed in a completed Lost Tower slot guarantees an Expedition encounter on that node.

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

The central element is the Detonator, with a new Explosives UI appearing in the bottom-right corner. The objective is strategic Explosive placement 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: Relics with floating tooltips providing beneficial or detrimental modifiers (e.g., increased Elemental damage but higher item rarity from chests).
• Excavated Chests: Spawned by Explosives near Black Markers with the spiral symbol. These contain Artifacts, Logbooks, powerful currencies, Waystones, and high-end gear.

Deploy Explosives carefully, ensuring their area-of-effect (AoE) circles don't overlap for maximum efficiency. After placement, activate the Detonator. You can strategically retreat after detonation to engage enemies later with powerful 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. These are used with Dannig in your hideout to access the Expedition Pinnacle Map. Slot the Logbook, click "Open Portals," and enter a significantly larger Expedition with more Explosives.

This Pinnacle Map introduces Olroth, a challenging boss whose spawn chance increases with map level (indicated by a skull on the minimap). Defeating Olroth is crucial for obtaining Expedition Passive Skill Tree points (2x per victory).

Expedition Passive Skill Tree

Accessible via the Atlas Passive Skill Tree, the Expedition tree enhances the event. It's located in the top-right of the Atlas Skill Tree menu. 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 boosts. Then consider "Weight of History," "Unearthed Anomalies," and "Legendary Battles" for further, albeit more challenging, improvements. Avoid "Extreme Archaeology" due to its drastic reduction in Explosives.

Expedition Rewards

The main rewards are Artifacts, used to trade with specific vendors for gear. Exotic Coinage refreshes vendor inventories.

Expedition Logbooks unlock the Pinnacle Map and a chance to fight Olroth, yielding significant rewards including unique items. Increasing map difficulty increases Olroth's spawn rate and reward quality.
