ROK City Hall Building Requirements in Rise of Kingdoms
ROK Building Guide in Rise of Kingdoms
Rushing through the City Hall Levels is important and useful so I decided to give you a rough upgrade path for your buildings that you should follow.
Of course, you can also upgrade other buildings in between and this is just the fastest way possible.
Here's how you should handle the upgrades in ROK:
Walls in Rise of Kingdoms
You will need to keep your Walls up with your City Hall Level as a requirement before you can upgrade to the next City Hall Level, so there's no option to actually skip them so just upgrade them but upgrade them last before you start upgrading your City Hall.
Hospitals in Rise of Kingdoms
Hospitals are sometimes required to upgrade your City Hall - but they are normally vital for you so I recommend you to keep one of them up with your City Hall Level but also try to keep the others up to the highest level possible (max is 3 levels lower than your City Hall). Use boosters to not block them.
Academy in Rise of Kingdoms
Upgrading the Academy can be nasty because you can't research during the upgrade - but I highly recommend you to keep that up to the highest level possible for the simple reason that it will give you a research time bonus at every new level that will pay off in the long run.
Barracks/Archery Range/Stable/Siege Workshop in Rise of Kingdoms
Ultimatively you will need to max them out, latest to get some City Hall upgrades as well as new troop tiers.
My personal strategy here is that I always check my hospital capacity and once the unit count exceeds the hospital capacity I start upgrading the barracks, Siege Workshop, Archery range or Stable. I can't heal those troops anyway so I can rather do the upgrade and my hospitals will heal the wounded troops so I don't mandatory need to train new ones during that time
Storehouse in Rise of Kingdoms
The Storehouse is not only mandatory for some City Hall Levels, it's also very useful to hold more resources - for me it's important to keep that somewhat up with my City Hall Level.
Alliance Center in Rise of Kingdoms
Each new level here adds more times that you can get helped by your alliance and this will pay off in the long run - for me this is always one of the first upgrades I do once I enter a new City Hall Level simply because every single additional help will deduct the time something needs. Very important.
Trading Post in Rise of Kingdoms
Unless you'll be sending around a lot of resources there's no need to get the Trading Post past Level 13. You will only need it to be Level 24 when upgrading your City Hall to Level 25 so you normally have a lot of time to do that later.
Scout Camp in Rise of Kingdoms
In my opinion there's no real use to get past Scout Camp level 14 to get to City Hall Level 15
Farms & Gold Mines in Rise of Kingdoms
I recommend that you always upgrade one of them to the max level. There's no need to upgrade all of them at once and you will need them to unlock Tier 5 troops in the end. Otherwise there's no need to prioritize those upgrades or even use boosters, to be honest.
That's it, this is what upgrades you should prioritize on your way to get to City Hall 25 as fast as possible.
