Editing Expeditions

'''Expeditions''' are missions in ''[[Project Rebearth]]'' that allow players to explore unclaimed territory on the map. Each expedition covers a player-selected area and costs {{Icon|Food}}, {{Icon|Knowledge}}, and population based on the size of the area. Upon completion, expeditions yield {{Icon|Scrap}} and a random basic resource ({{Icon|Wood}}, {{Icon|Stone}}, {{Icon|Earth}}, or {{Icon|Glass}}).

== Costs ==
Expedition costs scale linearly with the area selected. The following table shows costs per 1,000 hectares (10,000,000 m²).

{| class="wikitable"
|-
! Cost !! Per 1,000 hectares !! Notes
|-
| Duration || {{#expr:{{BuildingData|section=expeditions|name=costs|data=duration}}*10000000/86400}} day || Base duration before distance bonus
|-
| Population || {{#expr:{{BuildingData|section=expeditions|name=costs|data=pop}}*10000000}} || {{#expr:{{BuildingData|section=expeditions|name=costs|data=pop}}*1000000000}} people per 100,000 hectares
|-
| {{Icon|Knowledge}} || {{#expr:{{BuildingData|section=expeditions|name=costs|data=knowledge}}*10000000}} || Paid upfront when launching
|-
| {{Icon|Food}} || {{#expr:{{BuildingData|section=expeditions|name=costs|data=food}}*10000000}} || Consumed during the expedition
|}

An additional '''{{BuildingData|section=expeditions|name=costs|data=distance}} hour''' is added to the expedition duration for every kilometer between the expedition area and the player's settlement. This distance bonus means nearby expeditions complete faster than distant ones.

== Yields ==
Expeditions guarantee base yields that scale with the area explored. The following table shows yields per 1,000 hectares.

|-
! Yield !! Per 1,000 hectares !! Description
|-
| {{Icon|Scrap}} || {{#expr:{{BuildingData|section=expeditions|name=yields|data=scrap}}*10000000}} || Old-world remnants found while exploring
|-
| Basic resource || {{#expr:{{BuildingData|section=expeditions|name=yields|data=basicResource}}*10000000}} || Random {{Icon|Wood}}, {{Icon|Stone}}, {{Icon|Earth}}, or {{Icon|Glass}} gathered en route
|}

== Affected By ==
{| class="wikitable"
|-
! Source !! Effect !! Description
|-
| [[Science League]] || Expedition cost -{{#expr:(1-{{BuildingData|section=choices|name=scienceLeague|data=effects|resource=expeditionCost}})*100 round 0}}% || Reduces all expedition costs by {{#expr:(1-{{BuildingData|section=choices|name=scienceLeague|data=effects|resource=expeditionCost}})*100 round 0}}%
|}

== Strategy ==
Expedition costs and yields both scale linearly with area, so the resource return per hectare is constant regardless of expedition size. The main variable is the distance bonus on duration: nearby expeditions are significantly faster than distant ones. Players looking to maximize {{Icon|Scrap}} income should prioritize large, nearby areas to minimize idle time.

The {{Icon|Knowledge}} cost ({{#expr:{{BuildingData|section=expeditions|name=costs|data=knowledge}}*10000000}} per 1,000 hectares) can be substantial for very large expeditions, so players should ensure they have adequate {{Icon|Knowledge}} reserves or a strong research economy ([[University]], [[Museum]]) before launching major expeditions.

Settlements in a [[Science League]] alliance benefit from a {{#expr:(1-{{BuildingData|section=choices|name=scienceLeague|data=effects|resource=expeditionCost}})*100 round 0}}% reduction in all expedition costs, making them well suited for frequent exploration.
