How to Play Thousand Sons in Warhammer 40,000 11th Edition

This is the section to read first, because the Thousand Sons army rule is more procedural than most and because the version of it that circulates most widely is a full edition out of date.

Cabal of Sorcerers. If your Army Faction is THOUSAND SONS, then at the start of your Shooting phase, one or more models from your army with this ability can attempt Rituals. To attempt one, you select a model with the ability that has not yet attempted a Ritual this turn, and select a Ritual that no model from your army has attempted to manifest this turn, then take a Psychic test for that model.

Read those two selection clauses carefully, because together they define your ceiling. Each model attempts at most one Ritual per turn. Each Ritual can be attempted at most once per turn across your entire army. There are only four Rituals. So the maximum number of Rituals you can manifest in a turn is four, and that is only if you have at least four models with the ability and all four attempts succeed.

The Psychic test. Roll 2D6. You may then optionally Channel the Warp, which adds an extra D6. If one or more doubles or triples were rolled during the test, that model's unit suffers D3 mortal wounds. If the model survives, the combined total of all dice rolled is your Psychic test result, and if it equals or exceeds the Ritual's Warp Charge value, the Ritual manifests.

Three official clarifications that change how you play it. All three are answered in the pack's own FAQ:

• You do not have to decide whether to Channel the Warp before rolling any dice. So you roll 2D6, look at the result, and only then decide whether to reach for the extra die.
• The doubles-and-triples mortal wounds apply only if you chose to Channel the Warp. An unchannelled 2D6 attempt carries no mortal-wound risk at all. This is the single most valuable thing to know about the rule.
• You do not have to sequence all your Rituals up front. Pick a model, pick a Ritual, attempt it, see what happens, then repeat.

Put those together and the mechanic is much friendlier than its reputation. Attempt the cheap Rituals unchannelled and risk-free; Channel only when you need a specific result and can afford the D3.

The four Rituals, with their Warp Charge values:

• Destiny's Ruin (5). One enemy unit within 24 inches and visible: re-roll Hit rolls of 1 against it, or re-roll any Hit roll if your test result was 10 or more.
• Temporal Surge (6). One friendly THOUSAND SONS or SCINTILLATING LEGIONS unit not in Engagement Range, within 24 inches and visible: a Normal move of up to D6 inches, or up to a flat 6 inches on a result of 10 or more. Either way that unit cannot declare a charge this turn.
• Doombolt (7). One enemy unit within 24 inches and visible, excluding Lone Operative models that are not in an Attached unit and are more than 12 inches away: D3 mortal wounds, or D3+3 on a result of 11 or more.
• Twist of Fate (9). One enemy unit within 24 inches and visible: improve the Armour Penetration of attacks against it by 1, or by 2 on a result of 12 or more.

Warp Charge 5 on an unchannelled 2D6 is a comfortable roll. Warp Charge 9 is not, which is why Twist of Fate is the Ritual you Channel for.

Sourcing note. The pack does not reprint Cabal of Sorcerers in full. Its Rules Updates section rewrites the rule's first paragraph and three of the four Rituals by name, which makes those parts first-party, and the FAQs above are first-party too. The Psychic test sequence and the Warp Charge values are read off a community rules mirror. We are telling you that here because it is the one part of this guide that is only partly backed by the pack.

The correction. Our own earlier army guide said Cabal Points are generated at the start of your Psychic phase from your Psyker characters and then spent on Rituals, and that you must keep a psychically pure army for the rule to work. There is no Psychic phase, there are no Cabal Points, and there is no purity requirement. That description belonged to a previous edition.

In 11th edition you spend a Detachment Points (DP) budget rather than picking one detachment. The budget scales with game size: roughly 2 DP at 1,000 points (Incursion) and 3 DP at 2,000 points (Strike Force). The Munitorum Field Manual points at the Warhammer 40,000 app for exact figures.

The Thousand Sons spread is unusually even, three detachments at each cost:

• 3 DP: Grand Coven, Hexwarp Thrallband, Rubricae Phalanx.
• 2 DP: Changehost of Deceit, Warpforged Cabal, Warpmeld Pact.
• 1 DP: Ritual of Regeneration, Sekhetar Cohort, Servants of Change.

Now the constraint that shapes list-building. Exactly two Thousand Sons detachments carry a Unique Tag, and it is the same tag on both. Servants of Change (1 DP) and Warpmeld Pact (2 DP) are both UNIQUE: MUTANT, and two detachments sharing a Unique Tag cannot be taken together. The other seven carry no tag at all.

We are confident in that in both directions. Servants of Change's tag is doubly first-party: the pack prints a UNIQUE: MUTANT banner on its page and its detachment rule says in words that it cannot be taken with another MUTANT detachment. Warpmeld Pact's tag comes from the Munitorum Field Manual. For the seven with no tag, we checked the Munitorum Field Manual's Thousand Sons section with a parser we validated the same day in both directions: run against the Astra Militarum page it correctly recovers eleven detachments and four tags, and run against the Grey Knights page it correctly recovers nine detachments and no tags at all.

Run the arithmetic and there are twelve legal multi-detachment armies at 2,000 points: eight that pair a 2 DP detachment with a 1 DP detachment for exactly 3 DP, three that pair two 1 DP detachments and leave a point unspent, and exactly one three-detachment army made of all three 1 DP detachments together. The ninth two-plus-one shape, Warpmeld Pact with Servants of Change, is the one the tag blocks.

No Thousand Sons DP cost is contested. The Munitorum Field Manual and Wahapedia's own detachment index agree on all nine, and the Munitorum Field Manual prints no increase or decrease marker on any Thousand Sons Detachment Point cost.

The menu divides into three whole-army identities at 3 DP, three mid-weight themes at 2 DP, and three cheap specialists at 1 DP.

Start here. Ritual of Regeneration (1 DP) is the right first pick. Every Ritual you successfully manifest heals D3 wounds on the unit that cast it, so it rewards you for engaging with the army rule without demanding any particular models. It works with whatever you already own and it teaches the core loop.

If you want one detachment to be your whole army. Rubricae Phalanx (3 DP) is the most straightforward: All is Dust adds 1 to your armour saves against every attack with an unmodified Damage of 1, which makes Rubric Marines close to immune to massed small-arms fire. Grand Coven (3 DP) is the sorcery flagship, with three once-per-battle army-wide psychic turns. Hexwarp Thrallband (3 DP) is the territory detachment, where holding objectives literally expands the area your magic works better in.

If you like war machines. Warpforged Cabal (2 DP) gives your vehicles a re-roll on Hit, Wound and Damage while a Psyker stands within 6 inches, and only one of the three otherwise. That and-versus-or is the whole detachment.

If you like daemons. Changehost of Deceit (2 DP) is the allied detachment. It lets you include Scintillating Legions daemons up to a points cap, hands them a 4+ invulnerable save against shooting near your Psykers, and hands your own units the army rule back through them.

If you like hordes. Warpmeld Pact (2 DP) lets your mutant units buy a wound-roll swing in either direction at the price of D3 mortal wounds a phase. Servants of Change (1 DP) is the cheaper mutant package, promoting Tzaangors to Battleline.

The remaining 1 DP specialist. Sekhetar Cohort gives Sekhetar Robots psychic attacks and a character-fed accuracy and repair package.

Our recommended first 2,000-point army is Warpforged Cabal plus Sekhetar Cohort, the most durable is Changehost of Deceit plus Ritual of Regeneration, and the right way to play a mutant list is Warpmeld Pact plus Ritual of Regeneration.

There is exactly one illegal pairing in this faction, and it is the one a reader is most likely to build.

[Warpmeld Pact plus Servants of Change](/40k/armies/thousand-sons/detachments/thousand-sons-mutant-tag-trap) costs 2 DP plus 1 DP, which is exactly the 3 DP Strike Force budget. The arithmetic is perfect. It is still illegal, because both detachments carry UNIQUE: MUTANT and two detachments sharing a Unique Tag cannot be taken together.

It is a genuinely convincing trap, and it is worse than an arithmetic trap because nothing in the maths warns you. These are the faction's two mutant detachments. They buff overlapping keywords, they both promote Tzaangors to Battleline, and a player who owns a pile of Tzaangors and wants to play them will reach for both. The cost is right, the theme is right, and the list is illegal.

Two shapes that look blocked and are not:

Servants of Change and Ritual of Regeneration and Sekhetar Cohort together. Three detachments in one army looks like it must break something. It does not. All three cost 1 DP, only one of them is MUTANT, and the total is exactly 3 DP. This is the faction's only legal three-detachment army.

Changehost of Deceit with a mutant detachment. Changehost of Deceit is about daemons, which feel like they belong in the same conceptual bucket as mutants, and readers assume a clash. There is none. Changehost of Deceit carries no Unique Tag, so it pairs legally with Servants of Change for exactly 3 DP, and with Warpmeld Pact for exactly 3 DP as well.

We never suggest the Warpmeld Pact and Servants of Change pairing anywhere on this site, in either direction, and neither detachment's page lists the other.

Three habits separate a Thousand Sons player who wins from one who owns a beautiful, expensive shelf.

Attempt your cheap Rituals for free. Because the mortal-wound risk only applies when you Channel the Warp, an unchannelled attempt at Destiny's Ruin costs you nothing but the roll. There is no reason not to attempt every Ritual you have a model for, in ascending order of Warp Charge, and only Channel when a specific result matters. New players Channel everything and bleed wounds all game; strong players Channel maybe twice a game.

Sequence the Rituals against the shooting they are buffing. Rituals happen at the start of your Shooting phase, which means every buff you land is available to every gun you fire afterwards. Twist of Fate improving Armour Penetration and Destiny's Ruin handing out Hit re-rolls are both worth far more when you resolve them before your heaviest shooting rather than after your light stuff has already fired into the target. The order you shoot in is a real decision in this army.

Count your models before you trade. A full 2,000-point Thousand Sons force is small and every model is expensive. Rubric Marines are durable but slow and cannot be replaced mid-game outside specific detachments. Score with the Rubricae, kill with the characters and the war engines, and remember that Temporal Surge moves a unit but explicitly stops it charging, so it is a repositioning and scoring tool rather than a charge enabler.

The standard on-ramp is Combat Patrol: Thousand Sons. It is the faction's entry boxed set and the closest thing to a starter set that exists for this army. We deliberately do not list its contents here: box contents are re-cut over time and we hold no first-party contents evidence for this one. Check the live box page rather than any contents list you read elsewhere, including our own older copy.

If you want a bigger single purchase, Battleforce: Thousand Sons is the seasonal bundle, and Boarding Patrol: Thousand Sons is a sealed entry point for Boarding Actions, which is a separate game mode with its own detachments and is out of scope for the guides in this set.

Building beyond the on-ramp. The kit almost every Thousand Sons army wants is Rubric Marines, which is your Battleline, your objective holders and the unit the entire Rubricae Phalanx detachment is built on. After that, Scarab Occult Terminators are your elite hammer and also carry the RUBRICAE keyword, so they benefit from All is Dust too.

Characters, and why they are not optional. This faction's army rule is carried by models, so the number of Psykers you own is the number of Rituals you can attempt per turn. Exalted Sorcerers is the most useful character box in the range for exactly that reason, and the only datasheet that can carry Grand Coven's Incandaeum. The Infernal Master is a second Psyker and one of only two models that can carry Warpmeld Pact's Bray Lord. Ahriman is the signature sorcerer, and Magnus the Red is the centrepiece a 3 DP detachment can afford to build around.

If you want the robot army, Sekhetar Robots is the only kit that turns on the Sekhetar Cohort detachment, which does nothing at all without them.

A catalog gap to be honest about. Several datasheets that detachments are built on have no exact box entry in our catalog, so their detachment pages link no box rather than pointing you at an approximate kit. That includes Tzaangors, Tzaangor Shaman and Chaos Spawn, which between them carry most of Servants of Change and Warpmeld Pact, and the Scintillating Legions daemons behind Changehost of Deceit. We do carry a Tzaangor Upgrades sprue, but that is an upgrade kit rather than a unit box, so we do not link it as the way to buy Tzaangors. Sending you to the wrong box is worse than sending you to none.

One piece of good news for buyers. Unlike several other factions in this set, the Thousand Sons Faction Pack publishes no Warhammer Legends section at all, so there is no headline character here that you might buy and then discover is illegal for matched play.
