Exploration is one of the main ways of growing your Province. Via the Explore page, a province may send out soldiers, at the cost of gc, to acquire additional acres.

On this page you will have the following information:

Exploration Costs (Soldiers)
Exploration Costs (Gold)
Available Uncharted Acres (also known as the Explore Pool)
Currently Exploring
Maximum Explorable Now

If you have the Soldiers and the Gold, you will be able to explore for Acres to grow your Province. Explore costs increase significantly when over Kingdom Median in acres.

Available Uncharted Acres

Available Uncharted Acres, also know as the Explore Pool, has the following features:

Starts at 200 Acres at the start of the Age.
It grows by 2 Acres per Tick ^{Age 111}
No pool cap. ^{Age 111} ~~It is soft capped at 1000 Acres~~
When a War ends, a provision of additional Pool is added to each Province for both Kingdoms.
Each Province will have 5% of their Land removed and added to their Explore Pool (minimum of 100 Acres added to Pool, regardless of how many are lost).
Explore cost formula: Land lost in combat reintroduced ^{Age 112}

Restrictions

The following restrictions are in place:

Provinces may not explore without the resources to cover the costs.
At least 50% of existing Acres must be built or undergoing construction.
The Explore Pool must be greater than 0 Acres.
Provinces can not explore more than their current Acres at once.
Kingdoms with less than 10 Provinces will have an explore penalty.

Effects of War on Exploration

The following penalties apply during war:

Exploration costs increased to 600% during active War and End of War Cease-Fire (or 300% during End-of-War Cease-Fire for Provinces below the Kingdom Median, including incoming explored Acres).
During End-of-War Cease-Fire, when under Median, explore time is reduced by 50%.

Changelog

Age 53

Explore costs will increase more drastically the more you explore.

Age 56

The explore formula will be tweaked to relate to the size of the kingdoms provinces. The more you are over the median the more expensive it will be to explore. If you are the only province in your kingdom it will be more expensive.
Paradise will remove acres from the explore pool, which will now grow 5 times faster (i.e 100 acres an hour) and also decay .5% an hour. This decay will not occur during war or end of war ceasefire.

Age 57

The explore formula base cost is increased, with modifications on cost for provinces above and below the median. War (including End of War Ceasefires period) and Fortified stance will have a cost multiplier of 5.

Age 58

Pool growth will be changed from 100 a tick to 50. Decay will be reduced to .25% per tick. In addition to the pool not decaying in war it will not decay if it is less than 10,000 acres.
The explore formula curve will be modified so as to push out the curve. We will continue to utilise relative size to modify costs.

Age 59

Explore formula: We've moved away from an exponential formula to something that is curved more gently. Increases and reductions to cost based on a provinces size relative to the kingdom are still in effect.

Age 60

Provinces over the median will not be able to explore more than 50% of their acres at a time.

Age 72

Explore pool - remove kingdomwide explorepool and replace it with province level exploration pools.
Explore Penalty - Kingdoms smaller than 10 provinces will see an increased explore penalty.

Age 76

Explore costs during End of War Cease-Fire will be the same as during war for provinces Median and larger (including incoming explored acres) (500%)
Provinces below Median (including incoming explored acres) will have reduced explore costs during End of War Cease-Fire (250%)

Age 107

Auto-explore based on pool size has been removed
- pool stops growing at 1000 acres, and resets at 2500 acres - additional acres do not get auto explored
End of war - Explore pool interactions will remain unchanged - if you are >1000 acres of pool you will auto-explore acres when War ends.

Age 108

cost is no longer discounted by Land lost in combat over the age

Age 111

explore pool cap removed
daily pool growth has been changed to 2 acres daily

Age 112

Land lost in combat reintroduced
