Expedition Logbook

Eventually, you might discover a Logbook. These are special maps full of buried treasure and relics. Essentially one giant dig site.

Here you can create an extremely long chain of explosives and go through a very high number of remnants, but be very careful. Many remnants have mods that can really brick your build, so you'll probably want to avoid those ones.

If you add too many remnants, you could easily make the encounter harder than you can handle. There are all sorts of interesting things buried under the ground in Logbooks.

You might find dripping caves or hidden pirate caches, but the most powerful encounter is Olroth, the ancient undead commander of the Knights of the Sun.

Defeating him will grant you unique rewards, as well as points to spend in the Expedition section of the Atlas Tree. So those are the endgame systems on the Atlas, but we're not done yet.
