Codex Adeptus Custodes Rules: New Army Rules & Ka’tahs

Games Workshop has officially revealed the comprehensive army rules for the upcoming Codex Adeptus Custodes, transforming the faction into a hyper-elite force of unmatched superhuman champions. The latest update introduces six distinct martial ka’tahs, overhauls defensive mechanics like Aegis of the Emperor, and scales up baseline statlines to represent the terrifying lore of the Emperor’s personal guard. Tactical commanders must adapt to smaller model counts, hyper-specialized datasheets, and entirely new resource management systems to secure victory on the competitive tabletop.

Introduction to the New Adeptus Custodes Codex

Overview of the upcoming Codex Adeptus Custodes and the shift toward a hyper-elite tabletop playstyle. The modern design philosophy moves away from horde-style attrition and pivots sharply toward elite execution. Every single miniature represents a massive investment in points and power. Because armies field fewer total models than previous editions, players must extract maximum efficiency from every activation, movement phase, and combat exchange.

The rules framework treats the golden host as mythological figures stepping onto the battlefield. This power scaling creates unique list building challenges and rewards tactical precision over sheer board saturation. Opponents face a wall of golden armor that requires dedicated anti-tank weaponry just to scratch standard line infantry.

The Evolution of Martial Ka’tahs

Replacing the Old Stance Framework

Previous editions restricted martial ka’tahs to a rigid system of two rotating tactical stances. The upcoming codex completely replaces that framework with six distinct ka’tahs that offer granular tactical options across the Movement, Shooting, and Fight phases. This redesign offers unprecedented battlefield adaptability.

Generals no longer lock themselves into a predictable cycle of combat postures. Instead, players select precise stances based on immediate tactical needs, allowing squads to react dynamically to enemy positioning and scoring requirements.

Understanding the Readied Status Mechanic

Units acquire the readied status at the start of the Command Phase. Activating a ka’tah consumes this readied status for the remainder of the turn, demanding careful timing rather than passive board-wide bonuses. Managing these states turns every turn into a puzzle of resource allocation.

If a player spends a readied state too early, subsequent phases lose vital tactical potency. Deciding when to hold back a readied status and when to expend it separates novice commanders from tournament winners.

Breakdown of the Six Distinct Ka’tahs

• Operational Compliance: Engaged or battle-shocked units remain fully eligible to start actions. , starting an action does not forfeit shooting eligibility.
• Kinematic Advancement: Selected readied units can move directly through all model types during normal, advance, or fall-back moves.
• Salvus Stance: Ranged attacks ignore all modifiers to Ballistic Skill, hit rolls, and wound rolls, completely mitigating standard terrain cover penalties.
• Rendax Stance: Melee attacks targeting non-Monster and non-Vehicle units re-roll hit rolls of 1 at the start of the Fight phase.
• Proctus Stance: Incoming melee attacks suffer a permanent minus-one penalty to their hit rolls.
• Lethal Integration: Melee activations gain Lethal Hits specifically against Monster and Vehicle targets.

Favoured Ka’tah Synergies in Detachments

Six of the thirteen total detachments feature a Favoured Ka’tah rule. Activating the designated stance triggers an additional bonus, such as Rendax dealing mortal wounds directly to engaged heavy targets. These synergistic layers encourage thematic list building around specific shield hosts rather than generic optimal builds.

Commanders must align their warlord traits and enhancements with these specific detachment rules to unlock game-winning combos. A well-timed Favoured Ka’tah activation can completely dismantle a heavily defended enemy objective in a single turn.

Elite Statlines and Hyper-Specialized Datasheets

Redefining Baseline Infantry Power

To offset shrinking army sizes, Games Workshop pushes the Adeptus Custodes datasheets toward true mythological power. Basic Custodian Guard squads now possess Toughness 7 and five Wounds per model, allowing standard line infantry to shrug off massive incoming firepower. Bolter fire and standard chainswords bounce off golden armor with absolute impunity.

Standard infantry squads also gain Sustained Hits 1 when operating near objectives, while Vexila attachments bolster Objective Control. This ensures that even small units project massive control over disputed areas of the board.

Squad Limitations and Positioning Strategy

Squad sizes are capped strictly at three models before adding independent characters, forcing players to rely heavily on individual model resilience and precise positioning. Losing even a single model from a three-man squad hurts unit output significantly.

Players must utilize terrain and line-of-sight blocking features carefully during movement phases. Exposing squads without adequate support leaves them vulnerable to concentrated anti-tank fire despite their impressive defensive profiles.

Character Upgrades and Legendary Units

Iconic characters and heavy support platforms receive massive rules boosts to anchor army lists. Trajann Valoris, the Captain-General, matches the raw combat output of primarchs like Roboute Guilliman. His aura grants re-rolls of 1 to hit and wound rolls, while his Moment Shackles relic provides a one-per-game choice of either three additional attacks or an improved invulnerable save.

Meanwhile, the Telemon Heavy Dreadnought steps out of Horus Heresy timelines into mainline tabletop games. The Telemon boasts Toughness 11, fourteen Wounds, and a 2+ armor save paired with a 4+ invulnerable save. Loadouts feature devastating heavy options like the Arachnus Storm Cannon and Adrathic Desolator.

Defensive Resurgences: Aegis of the Emperor and Daughters of the Abyss

Aegis of the Emperor Mechanic

Durability remains a core pillar of the golden host. The classic defensive rule Aegis of the Emperor returns to the faction, functioning as a reliable Feel No Pain 5+ specifically against mortal wounds, replacing older invulnerable save conferrals. This mechanic protects elite models from psychic spam and devastating mortal wound output.

Opponents who rely on mortal wound generation to bypass high armor values find their primary strategic weapon severely blunted. This baseline resilience allows Custodes players to weather psychic storms and specialized attacks without breaking formation.

Anti-Psychic Support from Sisters of Silence

Support elements also receive substantial defensive buffs via the Sisters of Silence. Anathema Psykana units utilize the Daughters of the Abyss rule to gain a Feel No Pain 3+ against psychic attacks. Their built-in Psychic Null aura projects a 6-inch radius protective field, granting nearby Adeptus Custodes units a Feel No Pain 5+ against psychic abilities to counter warp-heavy armies.

Including these specialized units shores up the faction’s historical vulnerability to psychic-heavy factions. Commanders running balanced lists find that the Sisters of Silence provide essential battlefield utility and anti-psyker deterrence.

Strategic Impact on Competitive Play

Resource Management with Low Model Counts

Tabletop lists require a fundamental shift in deployment and resource management. Smaller model counts mean every single loss severely impacts board control. Players cannot afford throwaway units or sacrificial screens.

Every model must contribute directly to scoring secondary objectives or eliminating priority targets. Precision movement and aggressive trading dictate whether a list dominates the tournament scene or falters under pressure.

List Building and Matchup Strategies

Pairing elite durability with flexible martial ka’tahs ensures that the Adeptus Custodes remain a terrifying obstacle for any opponent. Tournament lists must balance expensive character models with resilient troop choices to maximize activation utility.

Matched play opponents must bring dedicated multi-damage weaponry and heavy anti-tank options to deal with Toughness 7 infantry and high-wound dreadnoughts. Codex Adeptus Custodes rewards skilled generals who master stance timings and board positioning.
