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
The air inside the Inevitability tasted of ozone and ancient incense. Brother-Captain Arvann Stern stood motionless in the center of the Strategium, his eyes closed, listening to the psychic choir of the ship’s Navigators. They were screaming.
For the Grey Knights of the 66th Citadel, the Warp was not a mystery; it was a battlefield.
"The breach is widening, My Lord," Justiciar Tancred’s voice crackled through the vox, heavy with the weight of his Terminator plate. "The augurs show a tear in the veil near the Mandeville Point. The signature is unmistakable. Khorne."
Stern opened his eyes. They glowed with a soft, silver light. "Then the prophecy of the Libram of Malis is fulfilled. The Bloodthirster Ka’jagga returns."
He stepped toward the center pedestal, where a massive, silver-bound tome lay open. It was the Chapter’s tactical codex—not a mere book of rules, but a living record of every banishment performed since the days of Malcador. He ran a gauntleted hand over the script. The words seemed to shimmer, shifting to reveal the specific rites of dismissal required for this particular foe.
"Prepare the strike force," Stern commanded, his voice gaining the resonance of a cathedral bell. "We do not go to hold the line. We go to erase the stain."
Minutes later, the teleportarium hummed with world-ending energy. Stern and his Paladins stood encased in Aegis armor, their Nemesis force weapons etched with runes that bled white light. There was no fear, no doubt. To be a Grey Knight was to be the ultimate paradox: a soul so pure it could walk through hell and remain untainted.
With a thunderous crack that displaced the very atmosphere, the chamber emptied.
They materialized in a nightmare. The orbital platform was no longer metal and glass; it was a ribcage of bone and rivers of boiling gore. In the center of the carnage stood Ka’jagga, a mountain of fur and brass, swinging a lash that tore through reality itself.
" Stern roared, his psychic presence flaring like a supernova.
The Grey Knights moved with a synchronization that defied mortal training. Tancred and his squad formed a wall of silver, their storm bolters roaring in a rhythmic cadence that shredded the lesser bloodletters. Stern leapt forward, his Halberd trailing silver fire.
He didn't just strike at the beast's physical form; he struck at its essence. Every blow was a syllable of a banishing ritual found within the sacred codex. As the Halberd bit into the Daemon’s throat, Stern channeled the collective willpower of his brothers through the weapon.
"By the Emperor’s light," Stern whispered as the world began to white out, "I cast thee back into the abyss. Be forgotten!"
The explosion of psychic energy silenced the screams. When the light faded, the gore had evaporated. The platform was silent, cold, and empty.
Stern looked down at his gauntlet. A single drop of ichor remained, sizzling against the silver plating before vanishing. He looked at the holographic display of his wrist-mounted tactical feed—a digital reflection of the codex's wisdom. The entry for Ka’jagga pulsed once, then turned grey. Mission complete. The secret war continued. different sub-faction of the Grey Knights, or should we focus on a specific battle from their lore?

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.
