Before Any of This: Build the Station

None of the missions below exist for you until the Expedition Station is standing. It sits in the Pal branch of the technology tree at level 22 and costs 2 Technology Points, then wants:

Wooden Board ×10Stone ×100Paldium Fragment ×20Cement ×20

Stone and Paldium Fragment you will already have piled up by level 22. The Cement is the only real errand: a High-Quality Workbench turns 20 Stone, 1 Bone and 1 Pal Fluid into 10 Cement, so the 20 the station wants is two batches — 40 Stone, 2 Bone, 2 Pal Fluids. Farm the bone and fluid first and the build is a single evening.

You get exactly one per base camp. The cap is one station per camp, and it has to go up inside that camp's radius rather than out in the field, so a second station means a second base rather than a second building. Raid boss arenas refuse it entirely. That makes expeditions a reason to keep every base slot you own occupied — each camp adds one more mission that runs while you are somewhere else.
