In Black Clover, every person born with magic gets a grimoire, but not everyone gets one that is powerful. Most citizens have relatively weak power, while the best of the best become magic knights or leaders. In Black Clover, the most powerful grimoires are used by witches, magic knights, non-magic users, and devils alike. Asta is the obvious outlier in the grimoire distribution system for many reasons: he doesn't have magic and uses the rarest five-leaf grimoire.
Three-leaf, four-leaf, and five-leaf grimoires are the three categorizations for grimoires in Black Clover. The most powerful grimoires exist among all these categories, but typically, the more leaves there are, the stronger and rarer the grimoire gets. Many powerful characters using three-leaf grimoires either have rare magic or supplement their magic with other skills to strengthen it. Characters with other grimoires do the same, but some grimoires and magic types are stronger than others.
10. The Queen of Witches Uses a Blood Magic Grimoire
This Three-Leaf Grimoire Holds Unmatched Power
The Queen of Witches is one of the most powerful characters in Black Clover. She uses her three-leaf clover grimoire to control blood and control anyone she used her power on previously. This ability to control her opponents allows her infinite opportunities to use their magic for her gain. With the blood grimoire, the Queen of Witches can control powerful opponents, using them for her cause, and even creating a personal army.
While the Queen of Witches's grimoire is a relatively common three-leaf grimoire, her mastery of uncommon blood magic makes her grimoire one of the most powerful. She uses her blood magic grimoire to control others and heal, making her a formidable opponent. Even upon Asta's first encounter with her magic, he was held under her control and wreaked havoc on the Black Bulls. Her grimoire makes for a scary foe.
9. Yami's Katana Helps Him Wield Dark Magic
Yami's Dark Magic Is Slow but Strong
Light magic is strong, but Yami's three-leaf grimoire harnesses the equally powerful opposite: dark magic. Dark magic is easily one of the strongest magic types, but unlike light magic, dark magic can consume spells and has a significant effect on devils because of its close relation to devil magic. Yami has gone up against many powerful opponents with this magic grimoire. The only downfall of dark magic is that it is slow.
By using his katana, Yami overcomes dark magic's slow speed and makes the most of this grimoire's ability. He imbues his katana with dark magic, giving him more time to charge up for big attacks and allowing him to make fast attacks in the meantime. Yami's three-leaf grimoire is another relatively common grimoire that holds rare and powerful magic abilities within.

8. Finral Roulacase's Spatial Magic Grimoire Has Potential
Spatial Magic Is Used Offensively, but Finral Uses It Differently
Finral's three-leaf clover grimoire allows him to harness spatial magic. This rare ability is used in very different ways by the Roulacase family. While his family is well known for their offensive magic maneuvers, Finral struggles to use his magic confidently in that way. For Finral, the spatial magic grimoire allows him to create rifts in space, teleport people and objects, strengthen himself, and combine power with other magic users' spells.
Spatial magic has infinite potential, as seen in the Roulacase family. The spatial magic grimoire is one of the strongest, even if Finral struggles to use it effectively. Not that he is a complete failure; Finral is very important to many strategies used by the Black Bulls. Finral often teleports important fighters from one place to another and uses spatial magic to speed up attacks and take opponents by surprise. Spatial magic is somewhat underrated but undoubtedly powerful.
7. Charmy Pappitson's Cotton Grimoire Comes in Clutch
Cotton Magic Can Create Food Buffs for Team Members
While cotton doesn't bring to mind strength, Charmy's underrated grimoire produces almost infinite magic. Charmy spends much of Black Clover being underestimated because of her gluttony. But later in the series, and with training, Charmy's grimoire allows her to create food, objects, restraints, and magic buffs in battle. Charmy's magic comes in handy in almost every battle because of her unique recovery magic.
Charmy's cotton magic grimoire is a common three-leaf grimoire, but it does wonders to strengthen an army of mages. With Charmy's magic, mages around her won't have to worry about running out of steam on the battlefield. Charmy isn't the best at offensive maneuvers, but in terms of supportive power, Charmy takes the cake.
6. Zagred's Kotodama Magic Comes From a Five-Leaf Grimoire
Kotodama Magic Power Is Supplemented With Devil Power
The devil Zagred's five-leaf grimoire allows him to use kotodama magic, reincarnate, and perform devil possession. His kotodama magic is very widely applicable because it uses the power of words. Zagred only had to say a word to summon objects and manipulate the world around him. Using his grimoire, Zagred defeated a Wizard King, countless magic knights, and nearly all the elves. Zagred can create anything with just a word, altering reality and space. There are few grimoires with a stronger magic power.
Zagred can even reincarnate himself with his magic. It isn't until the future, when Zagred goes up against Asta, that he meets his power match. This is because of Zagred's devil magic and large stores of energy. With a regular opponent, Zagred's grimoire would easily have the power to defeat them. But up against another devil-power-wielding opponent like Asta, Zagred has a harder time

5. Zenon Zogratis Uses a Bone Magic Grimoire
This Grimoire Helps Zenon Defeat the Strongest Magic Knights
Zenon is another user of a five-leaf clover grimoire, allowing him access to bone magic and Beelzebub's spatial magic. Zenon's bone magic has infinite applications and proves itself lethal in battle. For example, Zenon easily defeated Yuno and Langris Vaude, then kidnapped William Vanfeance. Zenon's power is hard to beat, and it wasn't until Yuno obtained his second grimoire that he stood a chance against Zenon in a rematch.
With bone magic and otherworldly magic reserves, Zenon and his grimoire are formidable. With a five-leaf grimoire, Zenon also uses Beelzebub's devil power. After completely merging with Beelzebub and using 100% of his magic power, Zenon is almost unbeatable. It is only Yuno — a magic user with two four-leaf grimoires — who stands against Zenon's bone magic grimoire.
4. Julius's Coverless Grimoire Is One of a Kind
The Coverless Grimoire's Time Magic Has Infinite Applications
Julius Novachrono's coverless grimoire is quite mysterious with its infinite pages and no clear indicator of a leaf number. This is unlike any other grimoire in Black Clover, often explained by Julius's use of time magic. After all, with time magic there are endless possibilities and infinite power. Time magic is one of a kind, and its power quickly allowed Julius to become the Wizard King.
But it can now be assumed, following Lucius's possession of Julius, that Astaroth's devil power lives in Julius's grimoire. Astaroth is the devil with time magic, so even without a cover, this five-leaf grimoire can be identified because of its magic. But this magic makes Julius's grimoire even more impressive. With Astaroth's devil magic, this time grimoire is one of the strongest.
3. Yuno's Four-Leaf Grimoire Brings Luck
Yuno Is One of the Few Mages With a Four-Leaf Grimoire
Like the overachiever he is, Yuno has two grimoires, and both are insanely powerful. With wind and star magic, Yuno is one of a kind. The focus here is Yuno's first grimoire, a four-leaf grimoire with wind magic. Four-leaf grimoires are the uncorrupted predecessor of five-leaf grimoires. This wind grimoire carries luck and is guaranteed to be used by a strong mage.
This wind magic grimoire can knock people out, carry people, form objects, and eventually summon Sylph the wind spirit. Despite being a relatively common attribute, wind magic can be powerful with the right user. Yuno's skill and natural magic ability enhance this grimoire's inherent magic to unknown levels. With little effort, Yuno seems to rise to the top with his wind magic, earning a spot in the Golden Dawn.
2. The Star Magic Grimoire Brings Yuno to Another Level
Yuno Has the Rare Ability to Wield Two Grimoires
After Yuno gained the companionship of the wind spirit, Sylph, he also obtained star magic. This second star magic grimoire is certainly the strongest of the two he possesses. Star magic is a rare attribute, and by getting this second grimoire, Yuno now harnesses the grimoire's power to teleport, shoot light beams, and create defensive barriers. The applications are seemingly endless, and each battle proves a new way to use this unique power.
With this second grimoire, Yuno was even able to defeat Zenon Zogratis. With wind and star power combined, Yuno is upgraded to one of Black Clover's most powerful. Star magic, as the opposite of dark magic, is also wildly effective against the villains in Black Clover who use devil power. In recent battles, star magic has become one of the main lines of defense against their opponents.
1. Asta's Five-Leaf Grimoire Gives Him Multiple Powers
Asta Uses Licht's Sword Magic and Liebe's Anti-Magic
Asta's five-leaf grimoire is unique and powerful, giving him access to swords and anti-magic. This dual-powered grimoire is one of the rarest in Black Clover, with a long history to go along with it. Formerly Licht's grimoire, it has a troubled history that led to its transformation into a five-leaf grimoire. Because of this, it also gives access to Liebe's anti-magic. Five-leaf grimoires host devils, but they are also unique in other ways.
For one, five-leaf grimoires aren't unbound to their magic user. This means they can be used by multiple users and host devils indefinitely. That is why Liebe was in this grimoire in the first place. Because of the five-leaf grimoire's nature, Asta can use Licht's swords and Liebe's anti-magic. For an anti-magic user, Asta is lucky to have access to Licht's magic swords and Liebe's anti-magic to achieve his goals.
