Every Psyker Ability in Warhammer 40K, Explained: From Mind Control to Warp-Fire

One of the many fascinating things within the setting of Warhammer 40K is the existence of Psykers, who are individuals in this universe that possess some degree of psychic ability or powers. From the humans of the Imperium of Mankind to members of the majority of Xenos species, there will be some among them that will be able to perform certain feats that others won’t with the powers of their minds and their connection to the Immaterium.

Therefore, let’s take a look at all the abilities and powers that these Psykers possess in the galaxy of the 41st millennium, ranging from well-known abilities like telepathy and telekinesis, all the way to extremely unique abilities rarely seen outside Warhammer 40K.

From the human Psykers of the Imperium to various Xenos species, like the Eldar, the Tyranids, and even Chaos, abilities specific to one species or even a small group of them are permutations and combinations of abilities from the disciplines mentioned below. There are all the abilities mentioned in various supplementary lore material GW has provided for Warhammer 40,000 and The Horus Heresy.

1 Discipline of Telepathy: Mastery of Mind Control

One of the most common displays of psychic powers in the wider pop culture and media, the Discipline of Telepathy is used to categorize those Psykers that have the powers to control and manipulate the minds of their targets with just a single thought.

For example, Psykers who use telepathy can manipulate their targets, which include both friends and foes, to strengthen and weaken them, respectively. Moreover, they can also influence their decisions to achieve a favorable outcome for them, like making GW bring Rogal Dorn into 40,000 next (Please!). The list also includes:

• Telepathic Link: This ability enables the Psyker to connect to the mind of their target, making them contemplate and experience things that their target does, and even propagate it to others through the link. The Hive Mind that controls trillions of Tyranids across the galaxy simultaneously is the best example of this phenomenon.
• Compel: Enables the Psykers to compel their targets to do their bidding by leaving suggestions disguised as the target’s own thoughts or suggestions of a higher power. Tzeentch’s plans often utilise this ability on an even global scale.
• Demoralise: Psykers can use their powers to demoralise and mentally weaken their foes in battle, or even off the battlefield.
• Dominate: A Psyker can even use their telepathic abilities to dominate the cognitive functions and thought processes of their targets.
• Will Enforcement: The allows the psyker to mentally prompt an enemy to perform a simple and/or complex action against their will.
• Presence Erasure: A high-level psyker can almost completely erase their own presence, or even the presence of their numerous allies, from the mind of their targets. While they might be able to see you coming, their perception will be extremely hindered or off-balance.
• Mental Fortitude: Psykers can amplify the fortitudes of their own minds, as well as of their allies, during battle or highly tense situations so that they can face whatever comes their way.
• Psychic Shriek: This psychic scream is similar to a Banshee’s scream, but on a psychic plane, which can heavily disrupt or even completely shatter the minds of those who hear it.
• Terrify: Another manipulative telepathic ability that enables a Psyker to instill fear in their foes of anything that they wish.
• Puppet Master: This ability can only be used to its fullest extent by an expert-level telepathic Psyker, who can infiltrate the minds of their targets and assume full control over their bodies and minds, making them a flesh puppet that will do their bidding remotely for them.
• Misdirection: From hallucinations to disorientation, Psykers can use this ability to misdirect their targets.
• Mental Projection: A strong Psyker can use this ability to project an image of themselves in their targets’ minds, or even their own memories, to anyone they wish.
• Psi-Track: This ability acts like a mental radar for Psykers, which enables them to gauge enemy numbers and look out for any strong Psykers among the enemy ranks.

2 Discipline of Telekinesis: Mastery of Material Psychic Might

If the Discipline of Telepathy affects the psychic plane, then the Discipline of Telekinesis is the category of abilities and practices that enable a Psyker to manipulate the material world with their psychic might. In some cases, some of the strongest Psykers in the galaxy can also use their telekinesis to manipulate things that even material objects won’t be able to.

And in some very rare cases of extremely strong Psykers, they can manipulate the very fabric of reality itself, which makes the Telekinesis Discipline one of the most effective and sought-after powers in the galaxy. The list of telekinetic abilities includes:

• Telekine Dome / Telekine Shield: A Psyker can develop a dome / shield around themselves that can keep them safe from both physical and psychological attacks from their foes.
• Shockwave: A psychic Shockwave can be deployed by a Psyker, which, depending on their grade classification, can push back hordes of enemies and even destroy everything in a wide area of effect.
• Assail: Through their psychic might, Pyskers can interact with tangible objects and throw them at breakneck speeds at their enemies, turning them into pulp in an instant.
• Psychic Crush: Often seen being used by high-grade Psykers, like the Eldars, Psychic Crush is a brutal method of reaching out their arm and clenching their fist, entrapping their foe in a choking and crushing them under a mass of psychic force.
• Gate of Infinity: Through sheer focus and psychic might, a Psyker is able to open the Gate of Infinity, which is the power to tear open a hole in reality that leads straight into the Warp. This can often lead to the forces of Chaos and other Warp entities spilling out and destroying anything in their path.
• Objuration Mechanicum: A Psyker is able to make mechanical elements like gears, levers, wires, and even shafts to malfunction within a machine, ranging from small weapons to even tanks. This can also have a two-fold effect, as the Adpetus Mechanicus believes that the Machine Spirit of that machine was upset by something. which takes them out of the equation (while it’s a joke, you never know with the Mechanicus’ zealousness and blind faith).
• Force Barrage: A Psyker can create a large number of unseen Force Bolts, which can hit objects and individuals at crushing speeds without them even knowing what hit them.

3 Discipline of Divination: Mastery of The Immaterium

Similar to the abilities like Clairvoyance, which in popular media is concerned with the ability to see the future, the Discipline of Divination is a category in which Psykers gaze into the Warp and the deeper Immaterium to find answers they seek about the entirety of existence. The ones who practice this particular form of psychic abilities are termed as Diviners.

But unlike being limited to just witnessing and/or understanding reality, these Diviners are also, in rare and extremely favorable circumstances, able to manipulate events that are happening, have happened, or are yet to happen. The list of abilities under the Discipline of Divination includes:

• Foreboding: Since the Diviners are connected to the Warp during their actions, they can receive insights into the future regarding their fates on the battlefield. This means that they can see how their enemies will perform their next attack before they do it.
• Misfortune: High-level Diviners are able to pull the strings of fate just enough to open a chain reaction that will bring misfortune upon their targets. Tzeentch is the most infamous for doing this, which gave him the title of ‘Changer of Ways.’
• Precognition: This ability grants a Psyker an almost lifelike memory of what is about to transpire next in their future. Among the Primarchs, demigod sons of the Emperor, Sanguinius and Konrad Curze were known to have precognition, which made them see their own deaths.
• Scrier’s Gaze: The Scrier’s Gaze is a high-level divination ability that can grant a Psyker a bird’s eye view of the entire battlefield. This makes it easy for their allies to prepare countermeasures and deploy formations that will give them the edge.
• Prescience: The Psyker gets quick, blurry glimpses of the near future, which help them steer themselves and their allies during a fight.
• Warp Perception: A Diviner can perceive the changes in the flow of the Warp, which leads them to gauge changes in reality caused by major future-altering events and impending doom.

4 Discipline of Biomancy: Mastery of Psychic Biological Manipulation

While it may not be as awe-inspiring as the type of psychic disciplines mentioned before, the Discipline of Biomancy enables a Psyker to manipulate biological energy and metabolic processes with the power of their mind. This means that, along with becoming a healer for their allies, they can also cripple the ranks of their enemies by manipulating their biology.

The abilities range from transmuting the flesh of their targets to even making their targets more vulnerable and/or immune to certain things (but don’t ask them to try and bring back the Emperor of Mankind to life, unless you want the Grey Knights to pay you a visit). Thus, the Psykers using Biomancy are both a blessing and a curse on the battlefield. Their list of abilities also includes:

• Smite: Biomancers are able to shoot lightning from their fingertips and smite their targets with electricity created from Warp energies.
• Life-Leech: Psykers can literally rip the life out of their opponents on the battlefield, which is usually attributed to Chaos Psykers like the forces of Nurgle.
• Warp-Speed: Through high concentration and control, a Psyker can let the energies of the Warp flow through them, enabling them to use their body and travel at Warp-Speeds, which gives the anime protagonist-like abilities to just appear behind their enemies and beat them.
• Bodily Transmutation: A Biomancer’s greatest strength lies in the control of their bodies and how they can manipulate them to suit their needs. Among them, some have powers like transmuting their appendages to turn them into bio-weapons.
• Body Enhancement: In the most basic sense, a Psyker can enhance their own, as well as the bodies of their allies, by heightening their senses and strengthening their physicality, like giving real-life video game buffs.
• Disease Manipulation: Coming to the favorite activity of Grandfather Nurgle, the benevolent Chaos God, some Biomancers, like the ones blessed by the Great Unclean One, can even manipulate diseases and plagues within a being’s body. This leads to them suffering from pain, decay, and entropy on a level that can make even Asmongold look away in disgust.
• Regeneration: Since transmutation is part of their repertoire, some Biomancers are able to regrow lost limbs through a little bit of sorcery and magic added in.

5 Discipline of Pyromancy: Mastery of Psychic Offense

As the name suggests, the Discipline of Pyromancy enables a Psyker to use their psychic powers and create, control, and manipulate fire and flames, straight from the energy of the Immaterium. And since it deals with the sheer destructive power of energy, it is also considered to be one of the most dangerous psychic abilities in Warhammer 40,000.

The list of powers and abilities under the Discipline of Pyromancy includes:

• Spontaneous Combustion: By focusing their anger and hostility towards their target, Pyromancers can turn their opponents into ash bu making them combust with Warpfire.
• Fire Shield: A Pyromancer can create a giant wall of flames that can incinerate any projectile thrown towards them or their allies.
• Flame Breath: Pyskers are able to channel Warpfire through their bodies and blow forth raging flames from their mouths.
• Sunburst: Similar to Iron Man’s laser beams, Pyromancers are able to unleash a beam of white-hot Warpfire that will incinerate and even atomise their enemies.
• Fire Manipulation: In their most basic abilities, Pyromancers are able to control and manipulate Warpfire and flames generated from other sources.

6 Discipline of Daemonology: Mastery of the Warp and Chaos Powers

Since the Imperium of Mankind is surrounded by forces that are opposing and wishing for the end of all humankind, it has to be prepared to save itself from any kind of threat that appears. And since the threat of Chaos and the Warp is mostly intangible and appears in the form of Chaos Daemons, the Inquisition and other organisations within the empire, like the Scholastica Psykana, developed Psykers to deal with these forces.

The result was the Discipline of Daemonology, which deals with the detection, containment, capture, and banishment of daemonic Warp entities that pose a threat to the Imperium in any way. The list of abilities innovated under this discipline includes:

• Banishment: Once a Psyker well-versed in Daemonology tracks down and incapacitates a Chaos Daemon, they can banish it back into the warp, either by force or by extracting and using its True Name. The True Name is a concept of the name given to a being’s soul, which holds power over them.
• Teleportation: A Psyker can tap into the Warp to teleport themselves, someone else, or even objects from one place to another.
• Corruption Detect: Since they are trained in seeking out Chaos Daemons, these Psykers have a sense to detect Chaos Corruption within living beings.

7 Discipline of Psykana: Mastery of Unique Psychic Abilities

Overseen by the Scholastica Psykana, which is an Imperial organisation that trains and sanctions Imperial psykers, the Discipline of Psykana is the result of thousands of years of Imperial knowledge about Psykers and psychic abilities, condensed and applied practically.

These include the thousands of years of innovations and experiments that have enabled the Imperium to develop unique psychic abilities for its ranks, which are also used by Librarians of various Space Marine Chapters along with other designated and recognised Psykers. The list of abilities under the Psykana Discipline includes:

• Curse Manipulation: Usually seen in members of the Thousand Sons Traitor Legion, Curse Manipulation can inflict, mutate, and worsen a curse put on a target, usually through psychic abilities and sorcery.
• Soul Purification: Seen within the Grey Knights Chapter, the members of this secretive faction are able to purify a corrupted soul of their targets.
• Blood Manipulation: Witnessed within the Sanguinary Brotherhood among the Librarians of the Blood Angels Successor Chapters, these Psykers are able to control the very blood of their targets, using it to help their allies, while also using it as offense against their enemies. These include abilities like Blood Boil.
• Temporal Manipulation: Experienced within several Chapters when psychic might is unleashed, these Psykers are able to push their will outside normal time, messing with how it flows to tilt the fight in their favor.
• Weather Manipulation: Often seen within the members of the Rune Priests of Fenris, these Psykers under the Space Wolves Chapter can call upon storms and hurricanes, and change entire environments with their powers.

While there are still a lot of other abilities that have been witnessed in Warhammer 40,000, we have kept the list to the most basic and all-encompassing categories; all of them are slight variations of the main ones mentioned above.
