If you’ve spent any time opening chests or claiming event rewards in Clash Royale, you’ve probably stumbled across the rare, glowing Book of Books item and wondered what it actually does. Many players waste this ultra-valuable resource on low-rarity cards or upgrades they could finish with gold alone, so it’s critical to understand what does the book of books do in clash royale before you tap that ‘use’ button. This guide breaks down its functionality, best use cases, and common pitfalls to avoid so you get the most out of every copy you earn.
Core Functions of the Book of Books in Clash Royale
At its simplest, the Book of Books is a universal upgrade token that skips all requirements for one full level of any unlocked card in your collection. It doesn’t matter if the card is common, rare, epic, legendary, or even a champion – this item works for every rarity tier, no exceptions. If you’re still confused about what does the book of books do in clash royale when you first get it, just tap the info icon on the item to see a quick breakdown of its core functionality, but the short version is it eliminates all upgrade costs for one level of any unlocked card.
Unlike common, rare, epic or legendary books that only apply to one rarity tier, the Book of Books works for every card in your collection. That means you don’t have to hoard separate books for each rarity group, or worry about getting a book for a rarity you don’t currently need to upgrade. It also works no matter how many copies or how much gold you still need for the next level – even if you have 0 copies and no gold saved, it will jump the card to the next tier immediately.
It is the only in-game item that can skip both card and gold requirements for an upgrade, making it one of the rarest and most valuable rewards you can earn. To put its value in perspective, upgrading a champion from level 14 to 15 costs 500 champion copies and 100,000 gold, which can take 3 to 6 months of regular play to collect without spending real money. A single Book of Books cuts that entire grind down to one tap.
Best Strategic Use Cases for the Book of Books
Not all uses of the Book of Books are equal, and using it on the wrong card can waste thousands of gold worth of progression value. You want to prioritize uses that give you the biggest long-term benefit for your playstyle, rather than wasting it on upgrades you could easily complete with regular free rewards. These are the highest-value uses for most players:
I’ve seen far too many new players use their first Book of Books on a level 8 common card, which they could have maxed out in two weeks just from opening free chests and crown rewards. That’s a literal waste of months of progression value, so always prioritize cards you use every match first. You don’t want to burn this rare item on a meme card you only play once a month for fun, unless you already have all your main deck cards maxed out.
You get the most value from the Book of Books when you use it on the highest rarity, highest cost upgrade available to you, not on cards you can easily level with regular rewards. If you have a choice between using it on a legendary and a common, always pick the legendary, since the gold and copy cost for legendary upgrades is exponentially higher than lower rarity tiers.
Common Mistakes to Avoid With the Book of Books
The biggest mistake most players make is using the Book of Books too early on low-value upgrades, but there are a few other less obvious mistakes that can also waste its value. First, don’t use it on a card you haven’t tested in your deck first. You might think a new legendary card looks fun, but if you haven’t played at least 10 matches with it at its current level, you might find you hate its playstyle after you waste the book upgrading it.
Another common mistake is hoarding the Book of Books indefinitely. A lot of players keep their copy in their inventory for months waiting for a “perfect” use case, but they end up missing out on months of better match performance because they’re playing with underleveled cards. I kept my first Book of Books in my inventory for 3 months waiting for a new champion to release, only to realize I hated playing that champion when it dropped. I ended up wasting all that time I could have had a maxed Electro Giant in my main deck instead.
If you have a clear, high-value use case for your Book of Books right now, don’t hoard it indefinitely for a hypothetical future card that may not even fit your playstyle. It’s also important to note that you can’t use the Book of Books on a card you haven’t unlocked yet, so don’t save it for a champion you don’t have at least one copy of already. You’ll end up stuck waiting weeks or months to pull the first copy, while you could have used it on a card you already use regularly.
Don’t use it to upgrade a card just because it’s meta either, if it doesn’t fit your main playstyle. If you hate playing control decks, wasting a Book of Books on a meta control champion won’t help you win more matches, because you won’t enjoy playing the deck enough to practice with it.
How to Earn More Book of Books in Clash Royale
The Book of Books is a very rare reward, so you can’t farm it consistently from regular chests or daily tasks, but there are a few reliable ways to earn copies every few months. The most consistent source is the premium season pass, which almost always includes one Book of Books in the premium reward track for players who reach level 70 or higher during the season. If you play Clash Royale at least a few times a week, the premium pass is easily worth the cost just for the Book of Books alone, plus all the extra gold, cards, and gems you get along the way.
Special seasonal events and holiday challenges also often include a Book of Books as a top reward for completing all challenge tiers. These events usually run for 1 to 2 weeks, and require you to win a certain number of matches without losing too many times to claim the top reward. You don’t have to be a pro player to win these challenges either – most casual players can complete them with a solid meta deck and a few tries.
Very rarely, you can also find a Book of Books in the daily shop for a large amount of gems, or as part of a limited-time paid offer. It’s almost never worth buying with gems unless you have a huge surplus of gems you don’t need for other things like chest unlocks or challenge entries. Global tournament top rewards also include Book of Books prizes for players who finish in the top 10% of participants, but that’s only accessible to very skilled, high-rank players.
The only consistent way to earn a Book of Books every season is by purchasing the premium Clash Royale pass, so if you’re a regular player, that’s the best investment you can make for long-term progression. You can also occasionally earn copies from special community events or creator giveaways, so it’s worth following official Clash Royale social media accounts to stay updated on those opportunities.
At the end of the day, the Book of Books is one of the most powerful progression tools in Clash Royale, and using it wisely can shave months off your grind to max out your favorite deck. Now that you know what does the book of books do in clash royale, you can avoid the common mistakes that waste its value, and use it to push higher in ladder, win more challenges, and get more enjoyment out of every match. If you’re still not sure which card to use it on, take a look at your last 20 matches and see which card you used in every single one – that’s almost always the best choice.
