• Blasting Rod: A spell that originally belonged to Allan Bennett, Aleister's friend, and teacher. While Bennett and Aleister disguise it as a silver staff with the effect of sending the target’s refined magic power out of control to knock them unconscious without harming them, the true meaning of Blasting Rod is a support spell that, when called, amplifies the power/effect of Aleister's magic to 10 times that which the target believes it to be. Because the target's expectation of the power output will usually rise with every use so does that power. If for example, the target, after the range of the attack was increased by 10 times after the first use, expects the range to be that long, the range will be increased by 100 times of the original value the next time it is used. This weapon is what would enable a human-like Aleister to even match a Magic God in battle if they expect his power to be comparable to theirs.^[10] This spell can even be used on Aiwass if Aleister has summoned it.^[62]

• Abracadabra: One of the great achievements of Aleister Crowley, based on the most famous magic phrase in the world. It's often included in magic charms and magic circles rather than incantations, where its effect of curse reversal allows one to use it as a protective charm to divert enemy curses or even send them back towards them.
  • I supply lightning for thy death: Aleister can also use Abracadabra as a curse-reversal circle to capture, slightly twist and redirect one of the countless curses that fly around the world at all times and aim it at a target of his choosing by drawing out an upside-down triangle with the same letters arranged in a regular fashion. Since the curse is not his, he doesn't have to refine magical power and thus cannot be traced back to him.^[63] With it, he was able to twist a curse to target Misaka Mikoto, who was subsequently struck with such force that she convulsed as if she were a normal person struck by lightning, causing severe bleeding and incapacitating her on the spot.^[64][65]

• Karma: A complex spell developed by Aleister, developed from multiple sources of magic, both Western and Eastern.
  • Shadow Blade: First a large shadow gathers under the opponent and stabs them, leaving a black shadow blade in their torso. However, this shadow blade does not cause physical harm or even cause much discomfort to the victim after they recover from the initial shock.^[49][66] Instead, the shadow sword is a magic sword, the symbolic weapon meant to guide the summoning ceremony. While it is primarily something like an amulet that drives out negative power and protects the spell user, ‘drive out’ also means to ‘divert or guide in a convenient direction’. So if used correctly it can be used for summoning.^[67] Since Aleister is aware of Imagine Breaker, he developed the sword to be broken. If the sword is broken the shards will scatter everywhere, tearing the victim from within.^[66]
  • Karmic Beast: Two skeleton-like 4-legged magic beasts summoned by the shadow blade. One is made of chains with a handcuff as its skull while the other is made of chains with a bicycle gear as its skull. The handcuff-beast is viewed as a ring and symbolizes the female. The gear-beast is viewed as the sun and symbolizes the male. Both beasts emit a strange rainbow-colored light. The beasts are tough enough to not be damaged when rammed with a ten-ton truck at full speed. The two beasts will continue to spawn as long as the shadow blade that summons them is intact.^[49]
    • Karmic Retribution: If destroyed, a vague haze surrounds the person who destroyed it. This is based on the concept of karmic retribution, the idea that your own actions invite the result you receive, using the simplest karma, the karma of killing. The more beasts a person kills, the heavier and thicker the karma they bear grows. If the target tries to destroy or remove the karma they have received without taking care of the source of the spell, their karma will also increase as they bear the "karma of killing karma".^[49]
    • Magic Interference: The handcuff beast represents binding and stagnation and the gear represents acceleration. The karmic beasts can use this symbolism to interfere with spells being casted and send them out of control as long as the spells are based on colors.^[49]

• Spiritual Tripping: A technique through which Aleister conveys his meditation to someone else by connecting his body to the target's just like a voodoo doll and links their movements, allowing him to affect their perception and enter their mind. To use it Aleister forms various gestures relating to a weapon and three specific numbers appear from his palm in succession before a weapon appears in his hands.^[9] This paints a picture of the “weapon” in the target’s brain and creates a foothold for influencing them.^[9][40] The weapon is illusory and only visible to the actual target/s, but it will cause them real damage while leaving anyone and anything else completely untouched. Anyone who sees the actions will be hit with exactly the destructive power they imagined it will have. Aleister's top rate skill as a magician allows him to accurately instill people with an image of texture, sheen, weight, hardness, and power of the weapon he's mimicking; so even if the target is not aware of the weapon's identity or power or even if they try to imagine something else as a counter, the true nature of the illusory weapon will pull through.^[40] Since it all comes from the target’s own brain, physical distance will not cause a drop in accuracy.^[68] Additionally, if someone targeted by this technique does not die through its effects, that person will essentially bear a curse saying that, from that point on, every choice they ever make will end in failure.^[69]
  • Flintlock: An old-fashioned flintlock gun, created using the numbers 32, 30, 10.^[10]
  • Claymore: A gigantic double-edged sword nearly as tall as Aleister himself, created using the numbers 1, 27, 5.^[9]
  • Staff: A twisted staff made of silver, created using the numbers 28, 4, 29.^[69] This is the staff used to disguise the use of Blasting Rod.
  • Fencing Sword: A sharp fencing sword, created using the numbers 13, 5, 32.^[10]
  • Big Bang Bomb: Aleister mimics using a pair of binoculars to look at the enemy, like the military binoculars used to designate attack coordinates via laser or GPS. An aerial support Big Bang Bomb will hit the enemy with the power of a real Big Bang, blowing through the entire universe and contaminating them to the very last cell with radiation.^[40]
  • Gamma Knife: Aleister mimics holding a pencil-like gamma knife, the medical tool that uses radiation to operate a brain tumor inside the brain by burning away the tumor while bypassing the organ.^[40]
  • Scythe: A large silver scythe. It symbolizes the moon.^[33]
  • Golden Staff: A golden staff with a spherical head. It symbolizes the sun.^[33]
  • Others: Other spiritual weapons created by Aleister include a shield and a bow.^[9]

• Spray: Aleister has constructed a way to gather together the unpredictable sparks and spray caused by the collisions between phases that fail to become miracles, making them act as a lightning rod to guide his own magic as an invisible attack from an unexpected angle.^[10]

• A.A.A. Hijacking: Due to the A.A.A. being a weapon made to project and amplify Aleister's power, Aleister can take control of it even against the wishes of its wielder, using its weapons or even projecting some of his magic through it.^[70]

• Babalon Spell: A spell and type of blood sacrifice used by Aleister after shifting to one of her female bodies using Babalon, the Whore of Babylon, as a symbol of femininity. This spell can be used in two ways. In the first way Aleister charges the enemy surrounded by scarlet red light more sinister than fresh blood.^[57] In the second one, the spell shoots a powerful beam of red light, which Aleister can also project from any A.A.A. that is present.^[70]

• Crowley's Hazards: Aleister's existence surpasses the realms of what can be expressed through 0 or 1.^[15] Due to that, every alternate possible version of him born from the various ‘ifs’ exists. He usually restricts all of those versions to a single coordinate, because they won't necessarily cooperate with each other, which is why he gives off so many contradicting impressions. He can also let one alternative version branch out to appear somewhere in the world and disappear again at will, not quite teleporting but more like faxing. If fully released (i.e through his death), the amount of alternative Aleisters produced is 1,083,092,867 according to the Tree Diagram and the Reading Thoth 78's calculations.^[2] The alternative Aleisters are of various natures; some having mastered magic like the original, but many others are different,^[24] often not even human in appearance. If the current main Aleister is killed, apparently one of the hazards becomes the new main Aleister with a limited degree of control over the rest of the Crowley's Hazards.^[60] The subsequent main Aleister "Aleis-tan" possesses all of the capabilities of the original Crowley and seems to recognize herself as having the same history as the original Crowley suggesting that the consciousness is transferred if a new main Crowley is selected.
  • Possibility Sacrifice: Aleister is capable of sacrificing the Crowley's Hazards to boost the power of his magic and to handle the magic recoil of bigger spells.^[60]
  • Blood Sacrifice: If the Crowley's Hazards are killed, a red haze appears around the main Aleister. He can use this haze to summon red magic circles to use as a shield that scatters attacks instead of stopping them,^[30] but more importantly, it defrags and optimizes the main Aleister.^[11][30][71] This grants him a boost in power the more of the Hazards are killed, vastly enhancing his physical capabilities. Due to this, Aleis-tan was boosted to the point of being able to physically rival or even surpass saints like Kanzaki Kaori.^[30] Aleister can also use the red haze used to eject a possessing entity, as seen when she used it to eject demon Qliphah Puzzle 545 which was possessing Kanzaki, by shaping it into a spear-like shape.^[30]

• Space Launch: By drawing a symbol on the air using her broom, the female Aleister possibility was able to launch the Windowless Building into space. This technique used up about five Crowley possibilities, including the magic recoil absorption.^[72]

• Archetype Controller: Aleister is able to control archetypes, a psychological concept for a common understanding or sense of values that developed as each member of a race or group dealt with an identical problem in the same way. Somehow Aleister can create, send them out of the world, and even destroy them. For example, he can change the current archetype of Academy City that could be called as man's worship of science into an archetype that science is heretical. Kihara Noukan states that this power is so great that despite leaving the magic side, Aleister could affect its very foundation since it is still strongly influenced by him and the glory he brought to the archetype of modern Western magic during the Golden period.^[13] Kihara Yuiitsu herself is the one who refers to Aleister as the "Archetype Controller" and because of that key factor sees him as an insurmountable being unless the entire world were to become 'Kiharas'^[4][14] with Kihara Noukan commenting that fighting him would result in a fate worse than death for them. In practice, the Archetype Controller allows Aleister to divide groups into multiple portions and pit them against each other, however those that belong to both manipulated categories can act against him.^[4] The Archetype Controller was used to split the world into a magic and science side.^[73]

• Illusion Creation: Aleister can bend light to disguise his appearance, as seen when he took the form of one of the magical beasts summoned by Karma to ambush Touma and the others.^[6]

• Summoning: As a former member of the Golden Dawn, Aleister is very knowledgeable in the summoning of spirits, be it angels or demons, to use their power. In particular, he's able to summon the angel Aiwass, though this requires a complex ritual and a large source of AIM.^[62][74] While Aiwass is summoned, Aleister is implied to possess some form of quasi-immortality by distorting the circulation of his own life force using the attraction of a great being like Aiwass, similar to the technique used by Westcott, a founder of the Golden Dawn cabal.^[2][75] Additionally, Aleister (with preparation of a magic circle) is able to summon spirits to possess people, like he demonstrated using his own wife.^[76]

• Clairvoyance: Aleister can use the tarot to predict the future. For example, he was aware that his first daughter was doomed to die very young before he even met and married his wife,^[69] and he similarly foresaw and prophesied World War I.^[33]

• St. Margaret Anti-demon Spell: A Christian magic spell based on using the legend of St. Margaret as a symbol of stripping away a demon, stealing its power, removing the disaster, and retrieving peace. The spell is performed by Aleister stepping on a demon, weakening their power.^[24]

• Banner of the West: A sealing technique in which Aleister seals the target into the ground. Through the use of this technique, he could seal. In order to use the seal, he requires the banner of the west to be drawn unto the ground. When he sealed Coronzon, he interpreted a part of the network of Academy City's streets as forming the banner of the west despite them not being laid out for this purpose, turning the entire city into a seal in the process. This means, while the requirement of having the banner of the west drawn is a restriction, there are also various ways Aleister could use to get around this restriction.^[24]

• Neutralization of Western Magic: Aleister Crowley can negate all western magic. More specifically he can neutralize and hijack all magic based on theory of western magic he constructed and redistributed, due to knowing all backdoors and zero-day exploits in the technical system. Since this includes the very fundamentals of western magic even if a western magician were to use a spell invented in ancient Egypt that calls upon Anubis it would be negated as long as the magicians understanding of magic originates from Crowley's work. However with this there are also clear limitations to the ability. Extraordinary magicians like the Magic Gods or people like Mathers and Westcott that have developed their own unique magic system can use magic unrestricted of Aleister's ability.^[33] In other words, what isn't based on Aleister's teachings can't be negated this way.^[33]

With Bible

• Son of God Synchronization: A spell that synchronizes the user with the Son of God. The closer the magician becomes to the Son of God, the more they are purified and the more power they can demonstrate, becoming beings similar to Saints. As a result of this spell Aleister gains white wings and a halo appears above her head, a sweet aroma scatters around her like lily flowers, and she is enveloped by a purifying white light. Aleister's version of the spell is based on the pentagrammaton, the five letters used to represent the Son of God.^[34] Chant: "Those four hidden letters form a holy square which cannot be uttered by human mouths. The Y-H-V-H which indicate God himself are hopelessly inadequate and the puny human body cannot fathom his true essence. But people seek salvation. They seek a salvation they can understand with their knowledge. So let us construct a bridge by adding a Sh. The five holy letters are Y-H-Sh-V-H. That is, the Son of God. By combining the Father, the Son, and the Holy Spirit, humanity can see salvation for themselves!!"
  • Stigmata: Aleister's synchronization with the Son of God is higher than Mathers, and eventually Stigmata appeared on her body. Once enough wounds are present the spell makes Aleister temporarily transform into a mass of pure white light that scorches even the darkness of outer space. The power density of the spell is so high that it disrupts the power transfer from the ley lines in the earth to users of that power, like for example original grimoires.^[7][8][35]
• St. Christopher's Staff: A spell based on the legend of St. Christopher. Aleister can summon a silver staff and turn it into a small palm tree staff. When used as a blunt weapon Aleister can increase the palm trees weight way beyond what its volume or density suggests.^[35] Chant: "St. Christopher repented after serving the devil in search of the greatest master. The son weighed as much as the entire world, so that saint – when he could not bear the weight and nearly drowned – saw his true lord, the Son of God, in the staff he carried!!"
• Anti-Archangel flame spell: Aleister can use magic to create powerful flames, which she can use for a spell capable of banishing and destroying Christian Archangels. To use the spell, she first scrapes the bottom of her staff against the ground, creating blazing sparks. As a result, a protective circle appears around her and great waves of explosive flames burst out across the 180 degrees in front of her, strong enough to destroy Archangels.^[35] Chant: "Uriel is the excommunicated angel, a demon who fell to the depths of the earth. Uriel is one of the seven who was driven from their throne of light for humanity’s convenience and is not found in the stories of God. The canon is absolute. In the name of Pope Zachary, I shall smash your angel worship and thus your harmony with those four!!"
• Flame Transformation: A spell based on the Qliphoth which transforms flames into harmless white flower petals.^[35] Chant: "All is a creation of God, even the forces which have parted ways with him and lurk in the depths of the earth. My fingertips reach the Qliphoth! The appropriate knowledge drawn from there is neither good nor evil!!"
• Longinus Healing Spell: A healing spell based on the roman soldier Longinus being healed by the blood of the Son of God. With this magic, Aleister can use a drop of blood to heal even those on the verge of death, instantly healing their bodies as a gentle light envelops all their wounds.^[77] Chant: "Longinus was a blind soldier. He was the saint who pierced the Son of God’s side to confirm his death. The holy one’s blood dripped down the lance and entered Longinus’s body where it healed the foolish soldier’s eyes and revealed a visible world to him. This drop can produce miracles, so reopen the realm of possibility to this trapped one!!"
