Exploring, Construction & Building Formulas

Construction

Construction Time

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

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

Construction Costs

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

Modifier Type	Active	Otherwise
Double Speed	2	1
Race: Dwarf	0.5	1
Expedient Ritual	0.75 (if at 100% efficiency)	1

Raze Costs

Raze Costs = (350 + (0.0625 * Total land)) * Artisan Science Mod

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 * Personality * Tools Science * Dragon * Blizzard

• 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.

• Changes in Building Efficiency take effect gradually.

Modifier Type	Active	Otherwise
Race: Dwarf	1.25	1
Dragon: Gold	0.75	1
Spell: Blizzard	0.9	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 

• In general, the Max Effect of a %-Based Building is 25 x Base Effect (exceptions apply, refer to table)
• 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 of buildings is not affected by Building Efficiency (i.e., Homes, Stables, Dungeons can hold the specified number regardless of BE).
