Castle: Upgrade Requirements
Upgrading Castle is a tedious process for free to play players. It requires long term planning as gem requirements to upgrade it escalates fairly quickly.
Level 25 Castle is a prerequisite for Level 25 Academy, which is needed to unlock the coveted Tier 5 troops.
In this guide, we will discuss, where and how you can get Books of Covenant that are required to upgrade the Castle and the cost of upgrade.
VIP Special Privileges Chest
Books are available from multiple Special Privileges Chest in different quantities from all of them. VIP 2, VIP 4, VIP 6, VIP 10, VIP 13 and VIP 14 contains 100, 300, 500, 1000, 2000 and 2000 Books respectively.
Grinding Barbarian Forts
Farming Barbarian Forts for Books takes time, it can be exhausting and it shouldn’t be your primary method to obtain Books. Use Peacekeeping Commanders to either start a Fort rally or join you Alliance mate’s rally. The amount of Books that you can get depends on your damage dealt, which is why it’s better to start your own rally.
Purchasing Books from the Shop
For most players, this is the primary method of obtaining Books of Covenant. Each Book of Covenant costs 10 gems, which isn’t much by itself but the amount of Books required to upgrade higher Level Castle grows significantly. The best time to purchase Books is during the “More than Gems” event to get some extra value for your gems.
Alliance chests
You can get up to 10 Books whenever someone purchases Chests in your Alliance. It’s not much but everything helps.

When you don’t have the resources necessary to upgrade your Castle, do not use your Building or Research speedups (unless you need to use them in order to win an event). By doing so, you are reducing the idle time. For instance, if you max out your Buildings/Research but you don’t have the resources to upgrade your Castle, you will lose a lot of time without having to upgrade anything.
