SprueSentry strategy commentary, not official rules. The detachment rule, stratagems and enhancements here are read from the printed pages of Faction Pack v1.2. Thousand Sons were part of the 26 August 2026 faction pack reissue, so this is Faction Pack version 1.2 and was one day old when this page was written. Its Detachment Point cost, force disposition, Unique Tag and enhancement points are not in the Faction Pack; they come from the official Munitorum Field Manual v1.3, read on 27 August 2026. This detachment carries no Unique Tag. Only two Thousand Sons detachments do, Servants of Change and Warpmeld Pact, and both carry MUTANT, so for everything else Detachment Point arithmetic is the only thing that can block a pairing. Enhancement points are dataslate-volatile and are reprinted here only as a planning aid; the Warhammer 40,000 app is the authority.
Two clauses. Friendly SEKHETAR ROBOTS units' attacks have [PSYCHIC]. And friendly THOUSAND SONS PSYKER units gain Infusion (Aura): while a friendly SEKHETAR ROBOTS unit is within 12 inches of this unit, that robot unit's melee attacks have +1 WS. Note the aura sits on the Psyker and reaches out to the robots, so the robots want to stay near a character rather than the other way round.
One friendly SEKHETAR ROBOTS unit selects an objective it is controlling; that objective is secured. A scoring tool rather than a damage one, and the reason this detachment holds ground better than its model count suggests.
When a friendly SEKHETAR ROBOTS unit within 12 inches of a friendly THOUSAND SONS PSYKER unit starts an action, that action does not prevent the unit from being eligible to shoot. Doing an action and shooting in the same phase is how a small army scores secondaries without going quiet.
When an enemy unit targets a friendly SEKHETAR ROBOTS unit within 12 inches of a friendly THOUSAND SONS PSYKER unit, ranged attacks against your unit with a Strength greater than your unit's Toughness have -1 to wound. Note the condition: it only bites against attacks that were already wounding you efficiently, which is exactly the anti-tank fire aimed at robots.
SORCERER or EXALTED SORCERER model only. Soul Bound: in your Movement phase, at the start or end of this unit's move, select one friendly SEKHETAR ROBOTS unit within 3 inches and heal it D3+1 wounds. Kine-shielded Guardians: while this model is within 3 inches of a friendly SEKHETAR ROBOTS unit, this model has Lone Operative. The second clause is the quiet one, because it makes your character untargetable while he walks beside the robots.
SORCERER or EXALTED SORCERER model only. In your Movement phase, at the start or end of this unit's move, select one friendly SEKHETAR ROBOTS unit within 6 inches; that unit's ranged attacks have +1 BS until the start of your next turn. The cheaper enhancement and the one that turns the robots into a reliable gun platform rather than a durable one.
The only unit the detachment rule, all three stratagems and both enhancements name. Without one in the list this detachment does nothing at all.
See the box: price and offersAn eligible bearer for both enhancements and the aura source the robots need to stay within 12 inches of. This detachment is a character-and-escort package, not a robot package.
See the box: price and offersA second Psyker unit so the Infusion aura and the two 12-inch stratagem conditions can cover more than one part of the board.
See the box: price and offersBattleline bodies to hold what the robots secure, since a robot-heavy list is short on units even when it is long on wounds.
See the box: price and offersWalking Rampart heals robots and Sorcerous Invigoration heals Psykers, so the two halves of a Sekhetar list repair each other. Exactly 2 DP.
Cheap mutant bodies free the robots from screening duty and let them stand on the objectives Arcane Venting secures.
The strongest machine build in the faction and the one we would build first. Warpfire Infusion pays out for keeping Psykers within 6 inches of your war engines, which is the same habit Ensorcelled Animus already rewards. Exactly 3 DP.
Daemonic Illusions gives a 4+ invulnerable save against ranged attacks, which is the save robots most want and do not otherwise have. Exactly 3 DP.
Tzaangors take the fight forward and pay for it in mortal wounds while the robots hold the middle. Exactly 3 DP.
How to play Sekhetar Cohort in 11th edition: the 1-DP detachment that gives Sekhetar Robots psychic attacks, why the accuracy aura sits on your Sorcerer rather than on the robots, and why both enhancements are character upgrades.

SourceFaction Pack: Thousand Sons v1.2 (official GW PDF, legal for matched play from 26 August 2026)
Sprue Sentry strategy commentary for 11th edition, not official rules. Games Workshop updates points and rules regularly; always confirm against the current official rules and latest update before a game.
Sekhetar Cohort is the Thousand Sons construct detachment: a 1-Detachment-Point package built entirely around the Sekhetar Robots datasheet. It reflects Warhammer 40,000 11th edition (Thousand Sons Faction Pack v1.2, legal for matched play from 26 August 2026), which prints its full rules on a single page.
One thing to be clear about before you spend the point: this detachment does nothing without Sekhetar Robots in your list. The detachment rule names them, all three stratagems name them, and both enhancements exist to buff them from a character. There is no fallback clause and no partial benefit.
The second thing is a structural point that changes how you play it. This reads like a robot detachment, but every one of its best effects is delivered from a character standing nearby. It is a character-and-escort package wearing a robot detachment's clothes, and a list that buys robots without buying the Sorcerers to walk beside them will underperform badly.
It carries no Unique Tag, so it pairs with every other detachment the 3 DP budget allows.
This is SprueSentry strategy commentary, not official rules. Its Detachment Point cost, force disposition and enhancement points come from the official Munitorum Field Manual v1.3, read on 27 August 2026, and the Warhammer 40,000 app is the final word as points updates land. New to the army? Start with the Thousand Sons army guide.
Two clauses, and they point in opposite directions.
The first clause is quietly one of the better keyword grants in the faction. Giving the robots' attacks [PSYCHIC] plugs them into everything else the army does: Twist of Fate and Destiny's Ruin buff attacks made by Thousand Sons models generally, but a great deal of Thousand Sons support keys specifically off Psychic weapons and Psychic Attacks, and this is what lets a construct participate in the sorcerous half of the army.
The second clause is the one people misread. The aura sits on the Psyker, not on the robots. It is the Psyker unit that gains the Infusion ability, and it reaches outward to any robot unit within 12 inches. The practical consequence is that your robots have to stay near a character, and if your character dies your robots quietly get worse in melee. Positioning discipline runs from the robots towards the Sorcerer, not the other way around.
Note also that the aura improves Weapon Skill, which is melee accuracy only. It does nothing for the robots' shooting. The shooting fix lives in an enhancement.
Three, all 1CP, and notice how many of them repeat the same 12-inch Psyker condition. This detachment really is about escorting.
The sequencing habit: keep a Sorcerer within 12 inches at all times, because two of your three stratagems are simply switched off otherwise.
Two, and both are SORCERER or EXALTED SORCERER model only. Neither goes on a robot. This is the clearest signal that the detachment is built around a character escort.
The second half of Walking Rampart is the quiet reason to take it. Lone Operative means the model cannot be targeted by ranged attacks from more than 12 inches away, so your Sorcerer becomes effectively untargetable while he walks beside the robots. In a detachment where losing the character switches off the aura and two stratagems, buying the character protection is buying the whole detachment insurance. The repair is a bonus.
Both demand tight escort, at 6 inches and 3 inches respectively, which is tighter than the 12-inch aura. Plan your movement around the enhancement, not around the rule.
(Points come from the Munitorum Field Manual v1.3 and move with updates; confirm in the app.)
Key units. Sekhetar Robots are the only unit the detachment rule, all three stratagems and both enhancements name, and the detachment does nothing at all without them. Exalted Sorcerers are an eligible bearer for both enhancements and the aura source the robots need. The Infernal Master gives you a second Psyker unit so the aura and the two 12-inch stratagem conditions can cover more than one part of the board. Rubric Marines provide Battleline bodies, because a robot list is short on units even when it is long on wounds, and objectives are counted per unit standing on them.
What it pairs with. No Unique Tag, so every 2 DP detachment is legal for exactly 3 DP.
1 DP, which leaves 2 DP spare at a 2,000-point game. DP costs are not printed in the Faction Pack; the official Munitorum Field Manual v1.3 lists it at 1 DP with a Disruption force disposition and no Unique Tag, and the Warhammer 40,000 app is the final word as points updates land.
No. The detachment rule, all three stratagems and both enhancements name SEKHETAR ROBOTS. Without at least one unit of them in your list the detachment does literally nothing, and there is no fallback clause. Do not spend the point unless the robots are in the list.
On your THOUSAND SONS PSYKER units, not on the robots. The Psyker unit gains the ability, and it reaches out to any Sekhetar Robots unit within 12 inches to give that robot unit +1 WS in melee. So the robots need to stay near a character, and if the character dies the robots quietly get worse. Note it improves Weapon Skill only, so it does nothing for their shooting.
Occulus Infernum at 20 points, because it fixes the robots' shooting, which the detachment rule does not touch. Walking Rampart at 30 points is the better pick if your Sorcerer keeps dying, because its Kine-shielded Guardians clause grants him Lone Operative while he stays within 3 inches of the robots, and losing that character switches off your aura and two of your three stratagems.
No. It only applies to ranged attacks with a Strength greater than your unit's Toughness, so it does nothing against the massed light shooting that was already wounding you on 5s and 6s. It is a targeted answer to dedicated anti-tank fire aimed at your robots, and it also requires the robot unit to be within 12 inches of a friendly Thousand Sons Psyker unit.
