Dannig

Dannig is one of the NPCs you encounter in the Expedition league mechanic. He allows you to open and access Expedition Logbooks.

Accessing Lobook Expeditions

Players can access logbook expeditions by clicking on the 'Show Expedition Map' option and slotting in a logbook. This opens up the logbook interface which contains 2-3 locations, each belonging to one of the expedition factions. You can select the desired location and open the portals to the logbook area.

Buying Items

Dannig has another option, labelled 'Buy Items', but it is not yet confirmed if he still offers the option to trade Expedition currency of his faction - Knights of the Sun, for the currencies of other Expedition factions, like in Path of Exile 1.
