Expedition & Detonation Mechanics
Expeditions are marked by a light blue spiral icon on the Atlas map. You can guarantee an Expedition using an Expedition Precursor Tablet in a completed Lost Tower slot.
Upon entering an Expedition map, locate the central Detonator and four NPCs. The core gameplay involves strategically placing Explosives near Markers to trigger events:
- Red Markers: Detonating near these spawns Runic Monsters. Larger markers yield larger monster packs, enhanced by Unearthed Remnants.
- Unearthed Remnants: These relics offer beneficial or detrimental modifiers (e.g., increased monster elemental damage for higher item rarity from chests).
- Black Markers (Spiral Icon): Detonating near these spawns Excavated Chests containing Artifacts, Logbooks, currency, and high-end gear.
The Explosive UI shows the area of effect (AoE). Avoid overlapping AoE circles for optimal farming. Place all Explosives, then activate the Detonator. You can safely retreat after detonation to engage enemies later with AoE abilities. Death resets the map, but leaving the area doesn't end the event.
Expedition Pinnacle Map
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. This offers a significantly larger-scale Expedition with more Explosives and a chance to encounter Olroth, the Pinnacle Boss.
Olroth's presence is indicated by a skull on the minimap. Defeating Olroth is crucial for obtaining Expedition Passive Skill Tree points (double points per victory).
Expedition Passive Skill Tree
Located within the Atlas Passive Skill Tree, the Expedition tree enhances the event. Points are earned by defeating Olroth. The tree features Notable nodes and difficulty-increasing nodes for Logbooks. Each Notable node requires increasing Logbook difficulty.
Here's a breakdown of Notable nodes:
| Notable Expedition Passive | Effect | Requirements |
|---|---|---|
| Extreme Archaeology | Reduces Explosives to 1, but boosts radius by 150%, range by 100%, and reduces enemy life by 20% | N/A |
| Disturbed Rest | 50% more Runic Monster Flags | N/A |
| Detailed Records | 50% more Logbooks, Logbooks always spawn with 3x Modifiers | Disturbed Rest |
| Timed Detonations | 50% more Artifacts, Detonation chains 50% faster | N/A |
| Legendary Battles | 50% more Rare monsters, 50% more Exotic Coinage | Timed Detonations |
| Frail Treasures | 3x more Excavated Chest Markers, but they disappear after 5 seconds | N/A |
| Weight of History | 35% boost to Remnant effects | N/A |
| Unearthed Anomalies | Remnants gain an additional Suffix and Prefix modifier | Weight of History |
Prioritize "Disturbed Rest," "Detailed Records," and "Timed Detonations" for significant reward increases. Then consider "Weight of History," "Unearthed Anomalies," and "Legendary Battles" for further, but more challenging, improvements. Avoid "Extreme Archaeology" due to the significant reduction in Explosives.
Expedition Rewards
Artifacts are the primary rewards, used to trade with specific vendors for gear:
| Reward | Artifact Image | Use | Gear Type |
|---|---|---|---|
| Broken Circle Artifact |  |
Gwennen | Weapons |
| Black Scythe Artifact | Tujen | Belts and Jewelry | |
| Order Artifact | Rog | Armor | |
| Sun Artifact | Dannig | Used to acquire other Artifacts | |
| Exotic Coinage | Refreshes vendor inventory | N/A |
Each Expedition features one vendor. Artifacts are retained after map completion. Exotic Coinage refreshes any vendor's inventory. Expedition Logbooks unlock Pinnacle Maps for increased rewards and the chance to fight Olroth for exceptional loot and double Passive Skill Tree points.
