The Grey Knights aren’t your standard Space Marines. Every single member of the Chapter is a powerful psyker, meaning your movement and combat phases are layered with supernatural abilities. The Codex provides the specialized framework needed to run this elite "low model count" army. Key Features of the Grey Knights Rules:

Teleport Assault: The signature ability of the 10th Edition Grey Knights, allowing units to vanish from the battlefield and reappear in strategic positions every single turn.

Sanctic Disciplines: A unique set of psychic powers that buff your units' defenses, increase their movement, or unleash devastating mortal wounds on the enemy.

Brotherhood Detachments: Specialized rules that represent different fighting styles, from the rapid-strike Interceptors to the heavy-hitting Paladins.

Navigating the Grey Knights 40k Codex PDF vs. Physical Books

With the release of Warhammer 40,000 10th Edition, Games Workshop shifted how players interact with their rules. Understanding the difference between a static PDF and the digital "Index" is crucial for new players. 1. The Official Index (Free PDF)

At the start of 10th Edition, Games Workshop released the Grey Knights Index: Daemonhunters. This is a free, downloadable PDF that contains all the datasheets and basic rules needed to play the army immediately. It’s the most accessible version of the "Grey Knights 40k Codex PDF" for those just starting out. 2. The Warhammer 40,000 App

The modern way to access your "PDF" style rules is through the official app. When you purchase the physical Codex, you receive a unique digital code. Redeeming this code unlocks all the lore, datasheets, and army builders on your mobile device or tablet, providing a searchable, portable alternative to a traditional PDF. Competitive Tactics in the Current Meta

If you are looking through your Grey Knights rules, you’ll want to focus on these high-performing units:

Kaldor Draigo: The Supreme Grand Master remains a powerhouse, providing reliable charges out of deep strike.

Nemesis Dreadknights: These towering exo-suits provide the heavy firepower and melee punch the army often lacks elsewhere.

Terminators: Unlike standard Marines, Grey Knight Terminators can resurrect fallen brothers, making them incredibly durable objective holders. Staying Updated: Balance Dataslates and Errata

The danger of using an older or unofficial Grey Knights 40k Codex PDF is that Warhammer 40,000 is a living game. Games Workshop frequently releases:

Balance Dataslates: These adjust point values and core rules to ensure the game remains fair.

Errata/FAQs: These clarify complex psychic interactions or weapon profiles.

Always ensure your rules match the latest versions found on the Warhammer Community website under the "Downloads" section. Conclusion: Mastering the Silver Host

Whether you are downloading the free Index PDF or unlocking the full Codex through the app, the Grey Knights offer one of the most rewarding playstyles in the grim dark future. Their ability to manipulate the battlefield through teleportation and psychic might makes them a "high-skill, high-reward" army that can win games even when outnumbered.

Prepare your Aegis armor, sharpen your Nemesis force weapons, and let the Emperor’s light guide your tactical decisions on the battlefield.

While many seek out a "Grey Knights 40k Codex PDF" to master the tabletop strategies of Chapter 666, the true essence of these warriors lies in their unwavering sanctity and psychic might.

Incorruptible Souls: In over ten thousand years of service, not a single Grey Knight has ever fallen to the temptations of Chaos. This purity is forged through grueling trials and an unbreakable faith in the Emperor’s light.

The 666th Chapter: Born of a secret founding during the Horus Heresy, their origins are tied to Malcador the Sigillite and the legendary "Eight" who first took up the mantle.

Legendary Leadership: Figures like Kaldor Draigo, the Supreme Grand Master, have become myths in their own right, allegedly wandering the Warp itself and striking down daemon princes on their own turf. Mastering the Codex

The Codex: Grey Knights for the 10th Edition of Warhammer 40,000 released on August 9, 2025. While reviews generally praise the "high-speed" mobility the book offers, critics frequently describe it as a "cautious" update that relies heavily on existing staple units rather than a complete faction overhaul. Core Gameplay & Army Rule

The army's identity revolves around its signature Gate of Infinity rule (formerly Teleport Assault), which allows you to redeploy a set number of units each turn.

Mobility Focus: You can pick up units at the end of your opponent's Fight Phase and place them in Strategic Reserves, allowing for constant pressure and "uppy-downy" tactics.

The "Cautious" Critique: Reviewers from sites like Goonhammer note that while the movement is top-tier, the lack of significant datasheet updates means the army still struggles to "punch up" against high-toughness (T11+) targets in melee. New Detachments

The Codex introduced five new ways to play, though players often cite three as the primary focus:

Sanctic Spearhead: Specifically designed for Dreadknight enthusiasts. It provides powerful stratagems that allow vehicles to ignore terrain and hit harder against Monsters and Vehicles.

Hallowed Conclave: Focuses on Terminators, providing them with "Fall Back and Charge" to keep them from getting bogged down in "tarpit" combat.

Banishers: An aggressive, melee-heavy detachment that grants "Lethal Hits" or "Sustained Hits" on a successful Leadership test.

Augurium Task Force: A finesse-based detachment that allows you to redeploy an extra unit at the start of your movement phase. Standout Units

Purifiers & Castellan Crowe: Widely considered the "big winners" of the book. Purifiers gain improved wound re-rolls, making them highly effective anti-infantry when paired with Crowe. Paladins: Now get +1positive 1

Damage on the charge, making them terrifying in close combat, though they lost their previous "-1 to wound" defensive ability.

Grand Master in Nemesis Dreadknight: Remains the army's premier "problem solver" for heavy armor, especially with new weapon upgrades. Key Disappointments

The most significant complaint from the community is the removal of Kaldor Draigo

and Brother-Captain Stern from the 10th Edition Codex. Many players feel this leaves a "Draigo-sized hole" in the army's tactical options, specifically regarding his previous charge-reliability buffs.

For a full digital reference of rules, many players continue to use the Grey Knights section on Wahapedia.

Grey Knights Codex for the 10th Edition of Warhammer 40,000, released in mid-2025, serves as the definitive guide for fielding the elite, psychic daemon hunters of Titan. Core Gameplay & Army Rules Teleport Strike Force : The primary army rule, often centered around the Gate of Infinity

, allows Grey Knights units to be placed into Strategic Reserves at the end of an opponent's turn and redeploy almost anywhere on the battlefield in the following movement phase. Psychic Prowess

: Unlike previous editions, psychic abilities are now integrated into unit profiles as special weapon keywords or specific abilities, such as the Surge of Wrath

for Grand Masters, which provides re-rolls against Monsters and Vehicles. Hallowed Ground : Featured in specific detachments like the Warpbane Task Force Read the Codex : Take the time to

, this rule creates zones of consecration that enhance psychic powers and unit resolve. Key Detachments

The codex includes several thematic detachments, expanding on the initial Index rules: Teleport Strike Force : Focused on high mobility and tactical redeployment. Warpbane Task Force

: Optimized for pure damage output and re-rolls, particularly effective against daemonic or high-threat targets.

: A detachment noted for its specific stratagems, though community reviews highlight mixed internal balance. Book Contents Grey Knights Codex

The 10th Edition Codex: Grey Knights , officially released on August 9, 2025, is a 104-page hardback that transitions the Daemon-hunting sons of Titan from their temporary Index rules into a fully realized faction. Core Gameplay: The Masters of Mobility

The codex solidifies the Grey Knights' identity as the most mobile army in Warhammer 40,000.

Teleport Assault: This signature army rule allows you to remove units from the battlefield at the end of your opponent's turn and redeploy them in your next Reinforcements step.

Detachments: The book features five distinct detachments. While the Teleport Strike Force remains a staple for hyper-mobility, new options like the Warbane Task Force provide variety, though some require careful wording checks following the June 2025 balance update.

Psychic Might: Unlike previous editions where psychic powers were a separate phase, they are now integrated into weapon profiles and abilities, making the army much faster to play. Unit Highlights & Meta Shifts

Brotherhood Terminators: Widely considered the "gold standard" unit in this book. With Toughness 5, a 4+ invulnerable save, and the ability to return a slain model every turn via the Narthecium, they are exceptionally difficult to shift from objectives.

Nemesis Dreadknights: Remain a "photogenic" centerpiece but face challenges with raw power. Critics note that while they are mobile, the general Strength 6 on Nemesis weapons can make it difficult to crack heavy vehicles or high-toughness monsters in melee.

Paladins: In this edition, Paladins are often viewed as outclassing standard Terminators for pure offensive output, depending on current point costs. The Lore: Forbidden Secrets

The codex delves into the forbidden history of Chapter 666, including the Terminus Decree—the ultimate secret duty to kill or re-entomb the Emperor should he ever attempt to ascend or be reborn. It also reaffirms that the Grey Knights' gene-seed is unique, engineered directly from the Emperor's genome rather than a traditional Primarch. Grey Knights 10th Edition Codex Review | Warhammer 40k
