Blue Guild: The Lost Codex

When the required destination is available: Reach the surface near the site marked in your objective. The check allows up to 5 horizontal and vertical steps in total. No item must be recovered for this objective. If no suitable destination is available: Bring 3 Codex Leaf. An unfinished stage requires the full quantity of spendable stock after earlier quest claims. Handing it in takes up to that quantity from your current stock. Protected items do not count. A stage already marked complete stays ready even if those items are gone. The actual destination comes from your current world and quest marker. Accepted stages keep their assigned destination across later rebuilds. The standing gate uses how many stages of this questline you have handed in. A cleared dungeon can let the offer sequence advance before its hand-in, so the gate can be lower than the usual stage threshold shown here.
