Master the arcane arts of the Sons of Magnus with our comprehensive strategic guide for the 2025 competitive season.
Welcome to the Thousand Sons playbook for the 2025 competitive season. With the recent release of Codex: Thousand Sons for 10th Edition, the Sons of Magnus have undergone significant changes that reshape how they play on the tabletop. This comprehensive guide analyzes all aspects of the new codex and provides strategic insights based on the latest competitive analysis from top players and content creators.
The Thousand Sons have transitioned from a mono-build army centered around Magnus and Cabal Points to a more diverse faction with multiple viable playstyles. This playbook will help you navigate these changes and develop winning strategies for the current meta.
Multiple viable army builds beyond the previous Magnus-centered approach
Flexible psychic mechanics replacing the previous Cabal Points system
Strategic insights from top players for the current tournament meta
Ritual casting and warp manipulation
Durable infantry with invulnerable saves
High AP weapons and mortal wound output
The Thousand Sons excel at psychic warfare, combining devastating ritual effects with durable infantry and powerful ranged attacks. Their core mechanics revolve around strategic positioning of psykers, managing risk with ritual casting, and leveraging specialized detachment abilities.
The army rule replaces the Cabal Points system with ritual casting mechanics that echo previous editions' psychic phase. This provides greater flexibility while maintaining the army's psychic identity.
(WC 5/10+) - Select an enemy unit within 24" and reroll 1s to hit against it (or all hits on 10+)
(WC 6/10+) - Move a friendly unit D6" (or 6" on 10+)
(WC 7/11+) - Deal D3 mortal wounds to an enemy unit (or D3+3 on 11+)
(WC 9/12+) - Improve AP by 1 (or 2 on 12+) against a target unit
Magnus near a Mutalith Vortex Beast gets +3 to cast (+2 base, +1 from Mutalith), making high-value rituals very reliable
The Arcane Focus stratagem allows rerolling all dice when channeling, providing a safety net
The unit takes the mortal wounds from channeling, not just the psyker model, allowing you to distribute wounds across a squad
This system rewards strategic placement of psykers and risk management. While potentially less reliable than Cabal Points, it can provide more powerful damage boosts when successfully cast, especially with the boosted effects.
The codex features five distinct detachments, each supporting different playstyles:





Each detachment offers unique abilities and stratagems that support specific unit types and playstyles, allowing for diverse army building options.
Enhances the army's psychic weapons with powerful bonuses
Choose between +6" range, +1 to wound, or Devastating Wounds for psychic weapons
Each buff can only be used once per battle (unlike the index version)
Strong for Magnus and character-heavy lists
Notable enhancement: Eldrich Vortex of Alatariel (+1 strength and damage to bearer's psychic weapons)
+1 to armor saves against damage 1 attacks
Excellent defensive detachment for Rubrics and Terminators
Key stratagems enable fall back, shoot and charge capabilities
Best enhancement: Risen Rubricae (infiltrate two units of Rubrics or one unit of Scarabs)
Supports Vehicles and Sekhetar Robots
Vehicles can reroll one hit, wound, AND damage roll when within 6" of a psyker
Vehicles explode on 5+ instead of 6+ if near a psyker
Consider mobile psykers on discs to support the vehicles
Great for Predators, Defilers, and Forgefiends
Take D3 mortal wounds for -1 to be wounded (defensive) or +1 to wound (offensive)
Tzaangors gain Battleline and OC2

Extremely powerful for creating durable, mobile mutant units
Great for Mutaliths and large Tzaangor blobs
Thousand Sons psyker units gain 4+ invulnerable save vs ranged when near daemons
Daemons gain Cabal of Sorcerers ability when near Thousand Sons
Offers interesting disruption options through specialized stratagems
Somewhat niche compared to other detachments but offers interesting disruption options
Rubric Marines and Scarab Occult Terminators form the backbone of most armies
Magnus, Ahriman, and other powerful sorcerers provide crucial support
Mutalith Vortex Beasts, Sekhetar Robots, and other unique units offer specialized capabilities
Rhinos, Predators, and Daemon Engines provide firepower and transport
Understanding the strengths and optimal uses of each unit type is crucial for building effective Thousand Sons armies.
The backbone infantry of the Thousand Sons, these dust-filled automata provide reliable objective control and screening while contributing significant firepower with their inferno bolters or warpflamers.
Elite terminators with exceptional durability and firepower, these units excel at holding key positions and delivering devastating attacks with their combi-bolters and psychic powers.
These core infantry units form the foundation of most Thousand Sons armies, providing reliable objective control and combat effectiveness.
Durable presence for holding key positions
Protect valuable units from enemy attacks
Aspiring Sorcerers provide psychic support
Loadout considerations: Bolter squads now much more viable with AP-2; flamers still strong in many matchups

Scarab Occult Terminators represent the elite infantry of the Thousand Sons, combining exceptional durability with devastating firepower. Their improved AP-2 combi-bolters make them effective against a wide range of targets, while their inherent -1 to wound ability makes them incredibly resilient.
Primarch of the Thousand Sons, powerful psyker with devastating attacks and ritual casting abilities
Legendary sorcerer with redeployment abilities and enhanced psychic powers
Specialist in manipulating dice rolls and providing sustained hits
Versatile leader providing invulnerable saves and model revival abilities
Powerful combat character with devastating wounds and specialized abilities
The Thousand Sons feature a diverse array of HQ options, each providing unique abilities and synergies to support different playstyles and army compositions.
Down from 465 in the previous index
Increased from S9 previously
Bonus to psychic tests

Ahriman remains one of the most iconic characters in the Thousand Sons roster, offering powerful psychic abilities and strategic redeployment options. While his role has changed somewhat from the index version, his ability to redeploy three units provides exceptional tactical flexibility during deployment.
Can flip one dice to a 6 each turn
Provides sustained hits 1 for his unit
Still excellent and commonly taken at 85 pts (down from 105)
Compatible with Eldrich Vortex of Alatariel enhancement for extra damage
The Infernal Master provides exceptional utility through his dice manipulation abilities, making him a valuable addition to most Thousand Sons armies. His ability to flip one dice to a 6 each turn can be crucial for ensuring successful ritual casts or key attack rolls.

Exalted Sorcerers serve as versatile HQ options that can be tailored to different roles within your army. The standard version excels at supporting Rubric Marine units with its revival ability, while the Disc variant offers greater mobility and enemy disruption capabilities.
Powerful support monster with psychic enhancement abilities
New infiltrating units with heavy firepower and board control
Mobile skirmishers with deadly precision attacks
Enhanced transport with powerful offensive buffs
Specialist units provide unique capabilities that complement the core infantry and HQ choices, offering additional tactical options and synergies for Thousand Sons armies.

The Mutalith Vortex Beast has emerged as one of the standout units in the new codex, offering exceptional value for its points cost. Its ability to enhance nearby psykers' ritual casting makes it an excellent support piece for Magnus and other key psykers, while its improved ranged attacks allow it to contribute significant damage output.
Points: 90 pts/2, 180 pts/4
Deploy forward and gain defensive benefits
Heavy warp flamers (S5 AP-2 D1) and hellfire missile racks (S10 AP-2 D3)
Free overwatch or heroic intervention once per battle round
Additional options include melta guns or power claws with projectors. They hit on 4s, limiting their offensive output, but excel at midboard control and screening. Their infiltrate ability makes them excellent for early objective control and zone denial.
Tzaangor Enlightened with Fatecaster Greatbows have received significant improvements in the new codex, making them excellent mobile skirmishers. Their reactive movement ability allows them to reposition in response to enemy movements, while their improved shooting attacks make them effective at picking off characters and other high-value targets.
Carries up to 10 infantry models, providing mobility and protection
Units disembarking get +1 to hit and wound if targeting the same unit the Rhino shot at
Extremely effective delivery system for bolter or flamer squads
At just 90 points, the Thousand Sons Rhino has become one of the best transports in the game. Its unique ability to grant +1 to hit and wound for disembarking units makes it an exceptional delivery system for Rubric Marines, allowing them to emerge from the transport and immediately apply devastating firepower to a designated target.
Rubricae Phalanx detachment with durable Rubrics and Terminators
Warpmeld Pact detachment with Mutaliths and Tzaangors
Warpforged Cabal detachment with heavy tanks and daemon engines
The new codex supports multiple viable tactical approaches, each leveraging different detachment abilities and unit synergies. These approaches can be mixed and matched to create hybrid strategies that capitalize on the strengths of different unit types while addressing specific meta challenges.
Focus on durable Rubric Marines and Scarab Occult Terminators
Use Risen Rubricae to infiltrate a unit of Scarabs or two units of Rubrics into midfield positions
Support with multiple sorcerers providing psychic rituals
With Terminator Sorcerer (Lord of the Rubricae)
With Risen Rubricae enhancement
With Stave Abominus
For psychic support and invulnerable save aura
For mobility and offensive buffs
This 750-point core forms the foundation of an infantry-focused Thousand Sons army, leveraging the durability and firepower of Scarab Occult Terminators supported by key HQ choices. The Risen Rubricae enhancement allows for forward deployment of a Terminator unit, while the Rhino provides mobility and offensive buffs for additional units.
Utilize multiple Mutalith Vortex Beasts as centerpieces
Support with Tzaangor Enlightened for mobility and sniping
Use Tzaangors and Spawn for objective play and board control
Create an extremely resilient midboard presence
Field multiple heavy tanks and daemon engines with rerolls from nearby psykers
Use Ensorcelled Infusion for +1 to wound on vehicles
Deploy Sekhetar Robots for infiltration and objective play

Ideal for Thousand Sons given their abundance of psykers
Good for mobile units like Enlightened or Spawn
Great for Tzaangor units with Scout
Suitable for mobile characters and infiltrators
Your AP-2/AP-3 weapons cut through their armor, making Rubric Marines and Scarab Occult Terminators particularly effective. The high AP of your inferno bolters negates much of their armor save advantage, while your psychic powers can bypass their defensive abilities.
Your army offers a good mixture of anti-horde and anti-monster capabilities. Warpflamers excel against Tyranid swarms, while your high-strength weapons from Mutaliths and vehicles can effectively target their monsters. Mortal wound output from psychic rituals bypasses their toughness.
Your durable infantry can weather their damage output, while your AP-2 weapons cut through their armor saves. The Aeldari's reliance on mobility is countered by your ability to control the board with durable units and forward deployment options. Their relatively low toughness makes them vulnerable to your firepower.

Can weather mortal wounds and -1 damage hurts your efficiency. Their high toughness and damage reduction abilities make them resilient against your attacks, while their disease mechanics can threaten your expensive units.
Mass invulnerable saves limit your AP advantage. Their ability to ignore AP with invulnerable saves negates much of your weapons' strength, while their high volume of fire can threaten your expensive units.
Strong anti-psyker abilities can disrupt your game plan. Their ability to deny psychic powers and deal additional damage to psykers directly counters your army's strengths, making ritual casting more difficult.
When facing these challenging matchups, focus on leveraging your mobility and board control to secure objectives rather than trying to directly outfight their strengths. Adapt your secondary objective selections to maximize scoring potential against these specific armies.
Thousand Sons lack CP generation beyond Kairos Fateweaver in the Changehost detachment, so careful CP management is essential:
Prioritize stratagems that provide the most consistent value, such as Arcane Focus for reliable ritual casting and sticky objective stratagems for scoring. Save CP for emergency situations like Destined by Fate to protect key characters.
Reroll a psychic test including the channeled die. Essential for ensuring critical rituals succeed, particularly high-value ones like Twist of Fate or Doombolt when you need the enhanced effect.
Sticky objectives are always valuable for securing scoring positions. These stratagems allow you to maintain control of objectives even when outnumbered, which is crucial for primary scoring.
4+ invulnerable save for Tzaangors transforms them from fragile chaff into surprisingly durable objective holders, especially when combined with other defensive buffs from the Warpmeld Pact.
+1 to wound for a vehicle significantly increases damage output, particularly for high-strength weapons targeting tough enemies. Essential for vehicle-focused lists.
Fall back, shoot and charge for Rubricae units provides exceptional tactical flexibility, allowing your durable infantry to escape combat and still contribute offensively.
Position near Mutalith for +3 casting
10 Scarabs with Lord of the Rubricae
Scout + Temporal Surge + Twisted Mirage
Create impenetrable Tzaangor screens
The Thousand Sons excel when their units work in concert, creating powerful synergistic combinations that amplify their individual strengths. Understanding and executing these key combos is essential for maximizing the army's potential on the battlefield.
Position within 6" of a Mutalith for +3 casting (+2 base, +1 from Mutalith)
Use the Grand Coven's Kindred Sorcery rule for +1 to wound or devastating wounds
Apply Twist of Fate to a target before firing his powerful psychic weapons
Magnus the Red remains one of the most powerful units in the Thousand Sons arsenal, but requires careful positioning and support to maximize his effectiveness. By positioning him near a Mutalith Vortex Beast, you can achieve a +3 bonus to his psychic tests, making even the most challenging rituals highly reliable.
The Grand Coven detachment allows you to enhance his already formidable psychic weapons with additional bonuses, while the Twist of Fate ritual can further improve his damage output against high-value targets.
10 Scarab Occult Terminators + Terminator Sorcerer with Lord of the Rubricae
Apply Temporal Surge to position optimally
Use Infernal Fusillade to make bolters S5 psychic weapons
Pair with a Rhino for +1 to hit/wound after disembarking
Apply All is Dust and Implacable Guardians for maximum durability
This powerful combination creates an incredibly durable and offensively potent unit that can anchor your battle line while delivering devastating firepower. The Lord of the Rubricae enhancement ensures consistent hitting power, while multiple defensive layers make the unit extremely difficult to remove from the battlefield.
20 Tzaangors with Scout 6" followed by Temporal Surge
Deep strike a second unit using Twisted Mirage at 6" away
Apply Warped Vicissitude for 4+ invulnerable saves
Use Warpmeld Sacrifice for -1 to be wounded
Additional enhancements:
This aggressive strategy allows you to rapidly project force across the battlefield, threatening enemy positions from the first turn. The combination of multiple defensive buffs makes your Tzaangors surprisingly resilient, while their mobility and combat potential make them a serious threat that opponents cannot ignore.
Scout Tzaangors 6" forward
Deep strike another unit 6" from enemy lines using Twisted Mirage
Cast Temporal Surge for additional 6" movement
Create a 20-man screen with -1 to hit, -1 to wound, and 4+ invulnerable save
This strategy creates an extremely difficult-to-remove screen that can effectively "jail" enemy units, preventing them from accessing objectives or threatening your key units. The combination of multiple defensive buffs makes your Tzaangors surprisingly resilient, requiring a significant commitment of resources to remove.
The screen is extremely difficult to remove and can tie up enemy forces for multiple turns, buying time for your more powerful units to secure objectives and apply pressure elsewhere on the battlefield.
Infantry-focused list leveraging the durability of Rubric Marines and Scarab Occult Terminators with psychic support.
Mutant-focused list centered around Mutalith Vortex Beasts and Tzaangors for board control and resilience.
Vehicle-focused list utilizing heavy tanks and daemon engines with psychic support for maximum firepower.
These example lists demonstrate different approaches to building competitive Thousand Sons armies, each leveraging the unique strengths of their respective detachments and unit combinations.
The 10th Edition Thousand Sons codex offers significantly more diversity in playstyle than its predecessor. While no longer reliant on Magnus and Cabal points, the army retains its psychic identity while adding significant tactical flexibility. The multiple viable detachments encourage experimentation, and point decreases across many units enable more diverse list building.
The new Warpmeld Pact has emerged as potentially one of the strongest detachments in the codex, offering incredible board control and durability through its mutant units.
The Rubricae Phalanx provides excellent durability for your core infantry, while the Warpforged Cabal offers a surprisingly effective vehicle-focused approach.
Your strengths lie in durable infantry, reliable damage output through multiple avenues, and exceptional board control. Weaknesses include CP management, vulnerability to anti-psyker tech, and some reliance on successful ritual casting.
Just as planned.
According to top players and content creators, the Thousand Sons codex is positioned as a strong A-tier or potentially S-tier army in the current meta. The removal of Cabal points has freed the army from its previous mono-build approach, while the new ritual system maintains its psychic identity.
Several content creators have highlighted the Warpmeld Pact detachment as potentially the strongest option, offering incredible durability and board control through its mutant units, particularly when using the "jail" strategy with Tzaangors and the Twisted Mirage stratagem.
The Rubricae Phalanx is seen as an excellent option for more traditional Thousand Sons players, while the Warpforged Cabal offers a surprisingly effective vehicle-focused approach that wasn't viable in previous editions.
The reduced reliance on Magnus is seen as a positive change, making him a strong option rather than an auto-include, while the improved Mutalith Vortex Beast has become one of the most efficient units in the army.
