Exploring, Construction & Building Formulas

Exploration Costs

Soldier Cost

3 + 1/210 * ( Land - 300 + Min ( Land - 300, ( Land Explored - Land Lost ) / 2 ) )^1.03

GC Costs

( 3.16 * Current Acres - 17.4 * SQRT( Current Acres ) - 50 + Explored Mod ) * Personality Mod * War Mod * Fortified * Mills Effect

• Explored Mod = Total Land Explored - Total Land Lost in Combat - Currently Exploring
• if Explored Mod is higher than 0 then the value is ???? (still in research) else it is 0

Modifier Type	Active	Otherwise
Pers: Shepherd	0.7	1
War	2	1
Fortified	2	1

Construction

Construction Time

Construction Time = 16 * Personality Mod * Builders Boon * Double Speed * Fortified

Modifier Type	Active	Otherwise
Pers: Shepherd	0.7	1
Builders Boon	0.9	1
Double Speed	0.5	1
Double Speed in Protection	0.75	1
Fortified	0.8	1

Construction Costs

Construction Costs = Race Mod * Personality Mod * Mills Mod * Double Speed * 8/31 * (Land + 2900) 

Modifier Type	Active	Otherwise
Race: Dwarf	0	1
Pers: Shepherd	0.7	1
Doublespeed	2	1

Raze Costs

Raze Costs = (1400 + Land) / 4

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)* Stance * Science * Dragon] + Race + 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 Buildings as well as Libraries.

Building Efficiency Change Rate  =  Formula

• Changes in Building Efficiency take effect gradually.

Modifier Type	Active	Otherwise
Race: Dwarf	0.2	0
Stance: Fortified	1.20	1
Dragon: Gold	0.75	1

Building Effects

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


Flat Rate Buildings = Base Effect * Number of Buildings * BE * Monarchy Bonus * Science

• Max Effect of a %-Based Building is 25 x Base Effect.
• With a 100% Building Efficiency, this is equivalent to building 50% of that building.
