How To Get Book Of Covenant and Castle Upgrade Requirement Rise of Kingdoms

Upgrading your Castle is one of the hardest things to do in Rise of Kingdoms. Only the power of the Book of Covenant can accomplish this. But because it is not generated by any event, the Book of Covenant is very difficult to obtain.

It will take a lot of time and effort to upgrade Castle, and the process can be painful. Remember that in order to advance your Castle to level 25, you must be active each and every day. This is crucial because, once your castle reaches level 25, you can raise your academy to the same level and begin 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 Kingdoms tips that are publicly available. The key aspects we’ll be talking about are Castle upgrade requirements, the cost of castle upgrades, and the fastest way to get the Book of Covenant.

How to get Book Of Covenant?

Well, it’s quite straightforward. All you have to do is start destroying forts as much as you can. As time goes on, your need for the required amount is going to exponentially increase. Just from level 24 to level 25, you’ll need 5,000 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.

Different ways of getting the book of covenant in the Rise of Kingdoms?

Ways of getting the Book of Covenant vary a lot in the Rise of Kingdoms. From very expensive ones like the VIP Shop Chest 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 the 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 the required tasks to complete objectives and missions and 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:

• You need to go far away from your alliance.
•  You will have to attack the forts with both of your accounts. While it’s quite hard to destroy forts that are level 4 (or) 5, you can easily go solo on forts that are levels 1,2, and 3.
•  The trick here is to start the rally on level 3 Fort with your main account, and then you just join the rally with your farm (second) account.
•  Furthermore, when you’re playing on your farm account, start rallying at Fort Level 2, and then proceed back to the main account and join the rally.
•  It’s quite easy once you get used to switching accounts. From that point on, you just need to repeat this as much as you can. 
•  It will be easier if you play Rise of Kingdoms on PC.

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 fourth increases, so does the drop chance (percentage) of getting the Book of Covenant. It seems easy, 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

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 only priority.

Keep in mind that you can’t upgrade your academy without having a castle at level 25. 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 your 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 technology that you can 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.)

Castle Upgrade Cost

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 and action points, it does end up being the most expensive building in the Rise of Kingdoms.

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
Level 1	0	0
Level 2	2	20
Level 3	5	50
Level 4	8	80
Level 5	15	150
Level 6	20	200
Level 7	30	300
Level 8	40	400
Level 9	50	500
Level 10	70	700
Level 11	80	800
Level 12	100	1,000
Level 13	125	1,250
Level 14	150	1,500
Level 15	300	3,000
Level 16	500	5,000
Level 17	700	7,000
Level 18	900	9,000
Level 19	1200	12,000
Level 20	1500	15,000
Level 21	1800	18,000
Level 22	2000	20,000
Level 23	2500	25,000
Level 24	3000	30,000
Level 25	5000	50,000
The total cost of all castle levels	20,095	200,950

Okay, but what does this mean for me?

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 gems.

For those of you who are interested in the cost of 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.

• action points 
• max drop of 5 books
• drops from every rally

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.
