Don't raise the parliamentary office

How it works

• The upgrade cost grows with the square of the current level: 450 × S² wood, 600 × S² food, 180 × S² iron, 220 × S² gold (S = current level).
• Example: going from level 3 to 4 costs 4,050 wood, 5,400 food, 1,620 iron and 1,980 gold.
• Duration depends on the target level: level 2 takes 30, level 3 60, level 4 90, level 5 120 seconds; for levels 6–10 it is 180 × 1.55^(target − 6) seconds, capped at 86,400.
• Example: level 6 takes 180, level 7 279, level 8 433, level 10 1,039 seconds; the duration is divided by world speed.
• While one upgrade is running on a member, a second cannot start; level 10 is the maximum and the button reads Office at Maximum Level.
• Resources are deducted from the active village; the office level, however, belongs to that member across the whole world and is not lost when you switch villages.

Step by step

1. Choose the member you want to develop in Han.
2. Check the office upgrade cost and the new effect.
3. If the resource is sufficient, order an upgrade.
4. Confirm that the new level and bonus have been processed into the member card.
