The Master Builder is a Gold Club feature that lets you queue additional building constructions — even when you don’t currently have enough resources. It costs 1 Gold per use, and the Gold is deducted when the construction begins.
How It Works
If your workers are busy or you lack the required resources, you can still queue the next construction using the Master Builder.
The queued construction will automatically start once:
You have enough resources, and
Your workers are free.
You’ll see the planned start time displayed on-screen, assuming your resources remain available. When construction is active, the Master Builder automatically uses available resources, including resources transferred from the hero.
Key Details
Each queued task costs 1 Gold.
The Gold is charged at the moment the task starts, not when you add it to the queue.
You can use this feature for any building or resource field upgrade, as long as you meet the building prerequisites.
