We'll list out all the important details you'll need to know about upgrading your City Hall in Call of Dragons.
In Call of Dragons, your City Hall is basically the backbone of your entire kingdom. Nearly every important feature and mechanic in the game — from unlocking stronger troops to increasing march queues and expanding your city — is tied directly to your City Hall level. Because of that, upgrading it should almost always be your top priority.
Each City Hall upgrade requires certain buildings to hit specific levels first, with the Wall being the most common requirement.
As you climb to higher levels, upgrades naturally become more expensive and time-consuming. This means you'll need greater amounts of Gold, Wood, Stone, and, later, even Blueprints to advance to the next level.

Tips on How to Upgrade Your City Hall Fast
There are a handful of useful ways that allow you to rapidly upgrade your City Hall in Call of Dragons.
The first recommendation we have is to unlock the second builder as soon as possible. This is simply because having two builders allows you to upgrade multiple buildings simultaneously. As a whole, you can almost double the speed at which you progress through City Hall upgrades.
We suggest you prioritize your Alliance Center and Research Building early. The Alliance Center gives more help requests from guildmates, while the Research Building boosts research speed. These two combined can massively reduce upgrade times later on.
It's also important to stay in an active Alliance. Alliances can help shave huge chunks of time off long upgrades, especially once you reach higher City Hall levels.
We also recommend saving speedups for major City Hall requirements or event rewards. Many of the best players in the game wait for Alliance help first, then use speedups to finish upgrades efficiently.
Overall, you should aim for important milestones like City Hall 12, 16, 17, 21, 22, and 25. These unlock major features like stronger troops and extra march queues that can dramatically improve farming speed and progression.
