One of the most difficult things to accomplish in Rise Of Kingdoms is to upgrade your Castle. This can only be done by using the power of the Book of Covenant. However, the Book of Covenant is extremely rare to get, since there is no event that generates it.
Upgrading Castle is a pretty long (and painful) process that will require a lot of time and dedication. Keep in mind that you need to be active every single day just to upgrade your Castle to level 25. This is important because if you have a Castle at level 25, you can then upgrade your academy to the same level, meaning that you can start researching your tier 5 troops.
With that being said, this guide is going to focus on Castle upgrades. Think of it as a combination of my personal in-game experience and some general rise of kingdom tips that are publicly available. The key aspects we’ll be talking about are: Castle upgrade Requirements, Cost of castle upgrades, and the fastest way of getting the Book of Covenant.
Well it’s quite straight forward all you have to do is to start destroying forts as much as you can. As the time goes one, your need for the required amount is going to exponentially increase. Just from level 24 to level 25 you’ll need 5000 Books of Covenant.
If you’re impatient and willing to spend money, this is the place where you can invest your gems. Regardless of what you choose to do, the best time to buy the Book Of Covenant is during the “More than Gems” event.
While I’m out here giving you good advice on what to do, in my beginner (noob) days I must admit I took the harder way. Farming barbarian forts like crazy and purchasing the Rise Of Kingdoms Book Of Covenant with all of the gems that I would get.
Ways of getting the book of covenant vary a lot in Rise of Kingdoms. From very expensive ones like the VIP Shop Chest all the way to the very tedious ones such as farming barbarian forts.
VIP Shop Chests – as mentioned, they are very expensive, but if you are looking to get the Book of Covenant alongside some golden commanders, it might be your way to go.
Spending Gems – If you don’t decide to spend gems on the Book of Covenants, trust me when I say that you will never upgrade your Castle to level 25. My advice is to spend your gems on Book of Covenant during the “More than Gems” event. It’s the best time to use gems, and you can also get nice rewards during the event itself. Whenever it’s up, just focus on doing required tasks in order to complete objectives and missions to claim your rewards.
Alliance chests – When someone in your alliance buys a chest in-game, you will have a chance to get the Book of Covenant (the amount that you most frequently end up getting is usually 10 books).
Farming barbarian forts – The name of the game here is to get the most Books of Covenant with fewer (lower) attack points. To achieve this, you first need a Peacekeeper commander and a farm account. Here’s how to do it:
After reading all of the bullets above, you’re probably wondering “Why on earth should I be doing this?”. The answer is simple, you should be doing this because as the overall damage count being dealt to the forth increases, so does the drop chance (percentage) of getting the Book Of Covenant. It seems easy and straightforward, but it took me so long to realize the importance of this.
Now that we have the Books of Covenant, let’s see how to upgrade our castle.
Castle upgrade requirements may not be your primary focus at the start of the game, but as soon as you get to the tier 5 troops, upgrading the castle will become your one and only priority.
Keep in mind that you can’t upgrade your academy without having castle at level 25. And what is more, to upgrade your castle to level 25 you will need to have all of your buildings upgraded to level 25.
The main point I want to raise here, and please read it carefully and repeat it to yourself every time you play Rise of Kingdoms and want to use your speedups: Don’t use your speedups on research when you get close to tier 5 troops without having castle and academy upgraded to level 25 before that.
What will happen if you start using speedups near tier 5 troops?
You’ll end up having max research that you can possibly have for academy level 24 and there won’t be anything left to upgrade. You will lose days and days without upgrading, just because you don’t have both castle and academy upgraded to level 25.
It happened to me, and I sincerely ask you to learn from my mistakes.
(BTW, that’s also the whole point of this entire website, to show other players all the mistakes I’ve made so that they hopefully don’t repeat them :D)
Believe it or not, Castle Upgrade costs in resources are not that expensive like upgrading a gold mine. But when you add the cost of gems, action points, it does end up being the most expensive building in the Rise of Kingdoms.
In order to upgrade your castle to level 25 you won’t need a blueprint that costs 2k gems, but you will need a lot of Books of Covenant.
Here’s a table overview of Castle Level Cost measured by the amount of Books of Covenant and the costs in Gems.
|Castle Level||Cost in Book of Covenant||Cost in Gems|
|The total cost of all castle levels||20,095||200,950|
If you look at the table, you will need 20,095 Books of Covenant to go from level 1 castle to level 25 castle upgrade.
When it comes to gems, for 10 gems you can get 1 book, meaning that the total cost is 200,950 in gems.
For those of you that are interested in Cost in action points, I have to be honest and say that it is almost impossible to get the right calculation, but we can get close to a rough estimate.
The calculation is based on:
In the end for 20,095 Books of Covenant, you will need to destroy 4,017 forts and that will result in 602,610 action points. Keep in mind, that this is a rough estimate because of the other factors that can impact the results like adding peacekeeper commanders, KVK Forts, getting drops without any Books, etc.
