Expedition guide — three permanent + three rotating

The two pools — static vs rotating

Expeditions split into two categories the system treats differently:

The three rotation slots

Every week, the rotation system picks one entry per duration bucket. The week's slot keys are stable strings; the picker uses them to seed a deterministic choice from each bucket's pool.

How the weekly pick actually works

The system uses the same weekly cadence as weekly contracts: the current week is computed from your client clock as unix_time / 604800 (one calendar week in seconds). That number, combined with a stable slot label like expedition_48h, deterministically selects an entry from the rotation pool.

Three useful consequences fall out of the determinism:

• Everyone sees the same active set each week. The pick is a pure function of week-number plus slot — no account-level RNG. Two players logging in on the same calendar week see the same three rotation expeditions.
• The region a rotation entry roams to also rotates. An entry's eligible_regions list defines where it can appear — the picker chooses one per week using the same deterministic seed. Caldera Descent might be in volcano this week and ruins next.
• First-clear bonus tracks per entry, per week. The system records which rotation entries you've cleared and which week-seed you cleared them under. The bonus fires exactly once per entry per week — repeat clears in the same week pay normal rates without the bonus.

Picking your week's expeditions

You have six expeditions in any given week (3 permanent + 3 rotation). Practical advice:

• Clear the three rotation entries first. The first-clear bonus only fires on rotation entries, and only once per week. Banking the bonus across all three every week is the steady-state correct play.
• Then use permanent expeditions to fill gaps. When your party finishes the rotation entries and you still have dispatch capacity in the week, the three forest entries are there. No bonus, but they're available.
• Read which region the rotation landed in. An expedition in your strongest region pays differently than the same expedition in an unfamiliar one — region modifiers stack. The roaming makes the rotation pool effectively much larger than 20 entries.

Common mistakes

• Missing the weekly rollover. The rotation refreshes once per week. If you don't clear the rotation entries before the rollover, that week's first-clear bonus is gone — there's no carryover.
• Expecting the bonus on permanent expeditions. The 3 forest entries don't carry first-clear weekly bonus. Running them is fine; expecting bonus rewards isn't.
• Locking your best party in a 48h expedition right before a boss raid window. Members on expedition are unavailable for other dispatches. Two days is a long time to bench your A-team.
• Assuming the rotation is random. It isn't. If a guide names a specific expedition as "this week's S-tier," they mean for the current global week-seed — not random luck. You can plan around the rotation, not hope for it.
