Exploring, Construction & Building Formulas

Soldier Cost

Exploration Soldier Cost = ROUND (3 + Metric/210 * War Status * Mills)

GC Costs

Exploration Gold Cost = Floor ((600 +  2.3 * Metric) * War Status * Mills)

where

Metric       = ( Full Metric + Half Metric )1.12

Full Metric  = Total Land - 300

Half Metric  = MIN (Full Metric / 2 , [Land Explored - Land Lost] / 2)

Construction

Construction Time

Construction Time = 16 * Racial Mod * Builders Boon * Double Speed * Expedient Ritual

Modifier Type	Active	Otherwise
Builders Boon	0.75	1
Double Speed	0.5	1
Double Speed in Protection	0.75	1
Expedient Ritual	0.8 (if at 100% efficiency)	1
Race: Dwarf	0.5	1

Construction Costs

Construction Costs = Race Mod * Mills Mod * Double Speed * 2/31 * (land + 11600) * Expedient Ritual

Modifier Type	Active	Otherwise
Race: Dwarf	0	1
Double Speed	2	1
Expedient Ritual	0.75 (if at 100% efficiency)	1

Modifier Type	Active	Otherwise
Retired
Pers: Shepherd	0.7	1

Raze Costs

Raze Costs = 350 + (0.0625 * Total land)

Buildings

Building Efficiency

Available Workers         =  Peasants + ROUNDDOWN ( Prisoners / 2 )

Optimal Workers           =  ROUNDDOWN ( Total Jobs * 0.67 )

% Jobs Performed          =  MIN ( Available Workers / Optimal Workers , 1 )

Building Efficiency       =  [ (0.5 * (1 + % Jobs Performed)) * Race * Scientists * Dragon ] * Personality

• The "Current Available Workers" value, provided by the Internal Affairs Adviser page, already takes prisoners into account.
• Building Efficiency affects all Flat Rate and Percentage-Based buildings.
• Building Efficiency has NO effect on Capacity component of Capacity Buildings as well as Laboratories.

Building Efficiency Change Rate  =  Formula

• Changes in Building Efficiency take effect gradually.

Modifier Type	Active	Otherwise
Race: Dwarf	1.2	1
Dragon: Gold	0.75	1

Building Effects

Percentage Based Buildings = Base Effect * BE * MIN(50%, % of building) * (100% - MIN(50%, % of building))


Flat Rate Buildings = Base Effect * Number of Buildings * BE * Scientists

• Max Effect of a %-Based Building is 25 x Base Effect
• If your BE is less than 100%, the effect you would have with 50% of that building is the maximum.
• If you have less than 100% BE, additional buildings past 50% will have no effect.

Build Table

Note: Capacity buildings are not affected by Building Efficiency (i.e., Homes, Stables, Dungeons can hold the specified number regardless of BE).

Retired buildings

• Shipyards: 1.5% chance of creating a boat, holds 5 boats per shipyard. 1 boat was needed per 100 troops sent to attack someone on another island.
• Universities: Produced 3 science points per acre
• Taverns: Lowered draft costs and mercenary costs
• Plazas: Employed extra peasants
• Strongholds: Increased OME (now Training Grounds)
• Mines: Produced a certain number of per acre
• Libraries: Increase in Science Effect (books)
• Schools: Protect a portion of science from Learn attacks (Learn Attack: Retired).
