Building installation or upgrade

How it works

• Cost = base × 1.55^(current level − 1); levels 0→1 and 1→2 cost the base price, then every level is 55% more expensive. Example: Lumber Camp 3→4 = 1,250 × 1.55² = 3,004 wood.
• The maximum building level is 20; no building upgrade costs gold.
• Duration (2nd and later villages): 1/5/15/45 s for levels 2–5; 180 × 1.55^(target − 6) + (unlock stage − 1) × 5 s for level 6 and above, at most 24 hours; the result is divided by world speed.
• In the capital levels 2–5 also take 1/5/15/45 s; level 6 and above follow the 240 × 1.42^(target − 2) + (unlock stage − 1) × 20 s curve (at most 24 hours, divided by world speed).
• The Sage's Building council duty shortens construction time by 8% at level 1 and 1% more per extra office level; at most 25%.
• Each village has one construction slot; a subscription or 600 diamonds unlocks a shared second slot. A second order cannot be placed on the same building.
• A stage upgrade cannot start while a construction is running; a construction order can be placed while a stage upgrade is running.

Step by step

2. Make sure all resources in the cost line are adequate.
3. Install the structure or press the Raise to Level ... button.
4. In Agenda, follow the Construction process order and the remaining time.
