Anti-Magic

Battle Prowess

Magic

Anti Magic: Asta uses this unique energy to nullify magic. Despite not having the ability to use magic, Asta's control over his Anti Magic energy, as well as the very uniqueness of this power itself has earned him the rank of an Arcane Stage mage.

Abilities

Expert Swordsman: Asta initially has a rough style due to having an unconventional sword and having only received basic training from Fanzell Kruger. Over time he develops greater skill through battle experience, additional swords, and ki-sensing.

No Magic Power: Asta possesses no mana and so is unable to use magic. This enables Asta to wield Anti Magic without suffering the weakening effects since he has no magic to drain. This also makes him undetectable to mana-sensors, and immune to the life-draining substance of the underworld.

Enhanced Strength: Asta possesses a high level of physical strength, able to do a thousand single-handed handstand push-ups, to swing heavy swords single-handedly, and to punch holes in rock walls with no injury to himself. Asta can swing his swords with such force that his opponents break stone when they crash. The Witch Queen further enhances his arm strength using Blood Magic.

Enhanced Speed: Asta is capable of moving in an above-average speed, which causes William Vangeance to think that he has used magic to aid himself.

Enhanced Durability: Asta possesses a high durability, as seen when he is able to keep standing up, despite receiving numerous attacks from Heath. He is even able to emerge from Licht's attempted cave-in relatively unharmed alongside Yami.

Enhanced Instinct: Asta possesses a heightened level of instinct, as demonstrated when he can unconsciously move his body in the best way to defend himself.

Ki: A principle originating from Yami's homeland, this allows Asta to use a sixth sense and to perceive and react to unseen attacks and people.

Keen Intellect: Despite his hyperactive and headstrong nature, Asta has shown to be intelligent and thoughtful in his own right. He understands many situations he finds himself in and can be tactical when needed such as cutting out curses with his swords and thinking of different tactics in battle. He is shown to be a fast learner, as he quickly learned to use Ki from Yami's guide in the middle of combat, as well as tapped into the dormant powers of the Demon-Slayer Sword by simply observing its original owner fighting.

Devil-Possessed: As a wielder of a five-leaf clover grimoire, Asta is connected to a devil that possesses Anti Magic, which grants him access to the energy. The more power he draws on, the more devil-like his appearance becomes. Asta agrees to a bargain with the devil: his right arm in exchange for more of the devil's power. This increase in power enables him to negate a Gravity Singularity and to coat additional weapons in Anti Magic; however, he is limited to 50 seconds of usage.
