Expedition

Expedition is the league mechanic of Expedition league, released in version 3.15.0 which the player can first encounter in Act 6. This encounter is considered Extra Content and has a baseline 8% chance to appear in any non-unique map area.

Overview

General Mechanic

The player will encounter one of the four Expedition NPCs amidst heaps of dirt, skulls, various small flags and so-called remnants. These remnants apply certain modifiers on explosion, which come in two different varieties. The first modifier — or a set thereof — applies to the monsters the player unearths with an explosion, the last modifier describes loot bonuses or extra experience. Both, locations of chests and difficulty of monsters, are indicated with markers. Whereas the skulls show monsters and more difficult ones are marked with bigger skulls on higher stakes, the flags are coloured according to the value of chest contents. White flags yield lesser, yellow flags middling and red flags yield loot of greater value.

The player can place up to four explosives in the area marked by dirt heaps, which detonate one after the other with a short delay. Each remnant affected by explosives will apply its modifiers to the monsters and chests unearthed around it and those of each subsequent explosion. After any explosion the player can loot the chests (unearthed monsters do not have to be killed for the chests to be accessible) and will find normal loot, special Expedition currencies and occasionally Expedition Logbooks. These logbooks can be crafted and, taken to Dannig, open portals to larger Expedition areas with more remnants, flags and more placeable explosives. These areas also contain loot in caves hidden behind rock walls, that have to be affected by an explosive to become accessible. Logbook encounters can spawn one of the Expedition bosses: Medved, Vorana, Uhtred and Olroth.

After completing an encounter the player can trade their currency on site with the respective NPC or in town.

Trading

Trading currency found in unearthed chests introduces a second layer of complexity to the Expedition mechanic. The list below shows which member of the Kalguuran expedition the player can trade their currency with. Each NPC offers a different set of items and while Gwennen reveals unidentified items upon buying (item class is visible, rarity is not), Rog lets the player reroll outcomes of several crafting options. Tujen sells currency and other items like fragments and gems, and Dannig offers his associates' currency.

Items

Expedition chests and monsters drop Expedition currencies as well as Expedition Logbooks. Modifiers to increased item quantity of the area will affect the drop rate of both.
