How do production bonuses combine?

How it works

• Specialisation percentages are summed first and then become one multiplier: Saw Mastery 5 × 5% = 25% and Forest Crews 5 × 3% = 15% give wood a 1.40 multiplier.
• All-production modules (Camp Chancery 1.5% per level, Provincial Administration 2%) are added to every resource's percentage.
• Council duty multipliers apply separately from specialisations and one after another; if two duties affect the same resource, both multiply.
• The alliance level bonus and world economy multiplier come last; stone also gets a ×2 and wood a ×1.30 boost.
• In worlds with the population rule the village ring multiplies on top of all of these: each worker on the Forest, Quarry, Iron Deposit or Fields raises that resource's final rate by 0.025% (600 workers give +15%).
• The temporary production boost (24 hours, 50 diamonds) does not change the rate; every hour during the boost counts as two hours of production.

Step by step

1. First, check the basic hourly production provided by the relevant production building.
2. Remember that building expertise has an impact on the sources that write only in the description.
3. Read the scope of the Han and Assembly mandate; some tasks contribute to all production, some to one or two sources.
4. Also track the remaining time of temporary production support.
5. Confirm the final result from the hourly production value in the source detail; this value on the screen is the applied version of the active effects.
