 Core Rules Changes for the 40k Balance Dataslate

• Practical impact: Expect fewer weird edge-case “gotchas,” and more consistent tournament rulings.

GW released the latest full 10th Edition Warhammer 40k Balance Dataslate in December 2025 and then a small FAQ and changes in January 2026, along with updated point changes to the Munitorum Field Manual.

Then be sure to read more about the latest Warhammer 40,000 point changes in our Munitorum Field Manual changes article, which breaks down each of the faction updates in detail.

The Warhammer studio dropped what may be the last 40k Balance Dataslate of 10th edition, because 11th edition should release in June, according to most industry insiders.

Regardless of timing, you know what that means for the meta: fresh rules, point tweaks, and a shake-up that could flip your army list on its head. 

This guide breaks down the newest 40k rules updates for 10th Edition so you can see what got buffed, what took a hit, and how it all stacks up at the table, until the next balance dataslate drops, that is.

March 2026 Balance Dataslate Changes

The latest Balance Dataslate update is fairly small, but it has some important changes:

• Tau, Tyranids, and Leagues of Votann get their official rules for new characters. 
• The Votann got a little change to make scoring easier. 
• Points adjustments for most factions. 
• Necrons C’tan spam got hit with points, Silent King excludes Monster units from his aura, and Necrodermal Binding abilities.

Big Winners From The Balance Dataslate, 40k Rules Update

The latest Warhammer 40k Balance Dataslate featuring 40k rules updates is here, and as always, it will shake things up across the competitive and casual meta.

This pass feels more like nudges and corrections than a full-on reset, which is often the healthiest kind of update. It still changes list math, mission planning, and what you can get away with in-game, but it does it without nuking every archetype.

It’s also worth noting that GW published some changes in each of the new Faction Packs, and not a big FAQ document. 

If you just want the fast hit list, the Change Index up top is the quick scan. The sections below are the “why this matters” version.

40k Balance Dataslate Winners: Imperial Factions

Adeptus Custodes

• What changed: Allarus, Custodian Guard, Vigilators, and Witchseekers all go down in points.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p4

Wardens have been dominating the spotlight, so this new Balance Dataslate update trims points on alternative infantry to tempt players into trying more of the range. It should lead to more balanced internal competition across their datasheets. Allarus, Custodian Guard, Vigilators, and Witchseekers also all go down in points. 

Astra Militarum

• What changed: No standout hits called out here, and the new detachment remains the headline.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p7

The new Grizzled Company detachment already gives Guard players a fresh way to bully the table. GW leaves them untouched since the detachment itself is expected to move the needle by a noticeable amount. Getting skipped in a dataslate tends to be a win when everyone else is eating changes.

Blood Angels (Updated March 4th, 2026)

• What changed: The Sanguinary Priest (Leader) can now join Bladeguard Veteran Squads.
• Verdict: Buff
• Official ref: Balance Dataslate v3.4, p9

Blood Angels come out looking meaner and a little easier to slot together. The Sanguinary Priest gaining access to Bladeguard Veterans is a sneaky quality-of-life upgrade that tightens up your midboard package. 

Dark Angels

• What changed: Ravenwing bike units drop; Azrael costs more.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p12

Ravenwing bike units drop, which is exactly the kind of support that the wing needed to function as a real list core again. Azrael pays a bit more since his baseline value was way above the curve, but he’s still strong. Players get a more flexible army without losing their lynchpin tools.

Grey Knights

• What changed: Interceptors and Purgation Squads both come down.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p17

Interceptors and Purgation Squads both come down, which helps the faction actually afford the support pieces that make their teleport tricks shine. The faction still plays elite and fragile, but with a little more cushion. With a decent win rate already, this should help them climb. 

Imperial Knights

• What changed: Crusader, Defender, Errant, Gallant, and Warden all drop.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p19

Several big Knight frames saw point reductions, which helps shake off the pressure they were under after the new codex launched. These drops open up list templates that were previously just a bit too tight. The Crusader, Defender, Errant, Gallant, and Warden all drop.

Space Wolves

• What changed: Several unique Dreadnoughts drop; detachment identity gets pushed.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p25

Saga of the Great Wolf becomes the faction’s marquee detachment, which encourages a fast, punchy, character-driven playstyle. Several unique Dreadnoughts drop, which supports that direction and adds durability to the package. Space Wolves get to lean into their iconic theme without sacrificing efficiency.

Chaos Factions: 40k Balance Dataslate Winners

Chaos Knights

• What changed: Despoilers pay extra for double guns; Ruinator and Desecrator drop.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p10

Despoilers pay extra for double guns, but the Ruinator and Desecrator drop, which nudges players toward more diverse loadouts. The balance between melee and shooting setups becomes easier to justify on the larger chassis. Like the Imperial Knights, most of the big Knights get buffs in this 40k Balance Dataslate update.

Death Guard

• What changed: Small alignment tweaks, including Land Raiders and Rotigus adjustments.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p13

The faction already had a major overhaul in the last update, so this one brings only small alignment tweaks. Land Raiders and Rotigus are adjusted to match broader changes across multiple factions. The faction holds steady, which is exactly what they needed after a stretch of turbulence.

Emperor’s Children

• What changed: Rapid Evisceration benefits transports; points shift across key picks.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p15

Court of the Phoenician unlocks a flashy new direction for the faction with Fulgrim finally stepping into the spotlight. Rapid Evisceration now benefits transports, which makes pressure lists flow much more smoothly. Spawn and Daemon Princes on foot get cheaper while winged Princes go up, giving the faction more list identity and room to experiment.

Thousand Sons

• What changed: Changehost of Deceit opens new interactions; several units drop.
• Verdict: Buff
• Official ref: Balance Dataslate v3.2, p27

Changehost of Deceit now lets Daemons benefit from Cabal points, which opens up a completely new hybrid playstyle that feels very on-brand for Tzeentch. Several units dropped, which helps the faction build wider without sacrificing damage output. Greater Daemons also get synced to the adjustments from the Daemon faction. 

40k Balance Dataslate Winners: Xenos Factions

Leagues of Votann (updated March 4th, 2026)

What changed: New character model added to the faction pack (rules already covered here). Votann can also use Brandfast Oathband, and Secure Positions can now be used at the end of any phase (buff).
Verdict: Buff
Official ref: Votann Faction Pack p6-8

Letting Secure Positions fire at the end of any phase is a real tempo upgrade. It makes the strat harder to play around and gives Votann more flexibility to lock scoring at awkward moments, which is exactly the kind of small rules tweak that adds up over an event.

Tau (updated March 4th, 2026)

What changed: New character model added to the faction pack (rules already covered here).
Verdict: Neutral (content update)
Official ref: Tau Faction Pack p6

This is more catalog support than a balance swing, still, who doesn’t want new minis? So, this is a buff overall. 

Tyranids (updated March 4th, 2026)

What changed: New character model added to the faction pack (rules already covered here).
Verdict: Neutral (content update)
Official ref: Tyranids Faction Pack p6

It’s a roster update, not a power-level shift, but getting new minis is always a win, so we’ll say it’s a buff. 

 The Losers From 40k’s Balance Dataslate

Adepta Sororitas

• What changed: Multiple unit point increases with no matching buffs called out here.
• Verdict: Nerf
• Official ref: Balance Dataslate v3.2, p3

Sisters were flying high recently with a great win rate, so some NERFS were probably needed. Units that were stacking buffs across previous updates finally get point increases to reflect their real power level. Seven units in total received NERFS without a single buff, so this might be a hard pill to swallow. 

Adeptus Mechanicus

• What changed: Cawl, Ironstriders, Skystalkers, Infiltrators, and Ruststalkers rise in points.
• Verdict: Nerf
• Official ref: Balance Dataslate v3.2, p5

Their previous glow up pushed certain units a little too high, so this dataslate brings them back to earth with several point hikes. The faction still has power, but you now need to commit more resources to fielding the strongest combos. Cawl, Ironstriders, Skystalkers, Infiltrators, and Ruststalkers have all raised in points. 

This basically hits the WCW winner’s list with direct NERFS. If you were planning on copying and pasting that list, you’re in for a rough night. 

Aeldari

• What changed: Multiple point increases plus rules tightenings aimed at top builds.
• Verdict: Nerf
• Official ref: Balance Dataslate v3.2, p6

A combination of point increases (seven units all go up by at least ten points, some by up to 20) and rule tightenings directly targets the strongest Aspect Host builds.

Star Engines become Assault, Skyborn Sanctuary requires eligibility to fight, and Fire and Fade loses the embark trick. Aspect tokens no longer help attached characters, which shuts down multiple-layered buffs. It is a targeted breakup of their most oppressive gameplay loops.

Black Templars

• What changed: Repulsor Executioners and Castellans rise; Crusade Ancient and Execrator drop.
• Verdict: Nerf
• Official ref: Balance Dataslate v3.2, p8

Repulsor Executioners and Castellans rise in cost since they were carrying the faction above the Marine curve. The Crusade Ancient and Execrator drop, which nudges players toward the new kits. These 40k Balance Dataslate Changes shift list focus but still keeps the faction competitive.

Chaos Space Marines (Updated March 4th, 2026)

What changed: Renegade Warbands now restrict access to Cults of the Dark Gods, to better represent their recent turn to Chaos.
Verdict: Nerf (restriction)
Official ref: Chaos Space Marines Faction Pack p10

This is a theme-forward constraint that also narrows list-building. Whether it is a light tap or a real hit depends on how important those options were to your builds, but any restriction like this reduces flexibility.

Deathwatch

• What changed: The Indomitor Kill Team climbs 15 points.
• Verdict: Nerf

The Indomitor Kill Team climbs 15 points, which pulls it back in line with equivalent elite choices. It still functions well, but no longer overwhelms internal options. They don’t have so many units, so a single one getting an increase is huge. 

Necrons (updated March 4th, 2026)

• What changed: The Silent King’s Szarekh aura suite and related Triarch-style abilities were updated to exclude Monster units, so they no longer affect Monsters. C’tan also went up in points, and Necrodermal Binding was changed.
• Verdict: Nerf
• Official ref: Balance Dataslate v3.4, p21

Necrons catch a pretty clear “cap the ceiling” pass here. The Silent King still hands out strong buffs, but the Monster exclusion shuts down some of the nastier stacking and prevents big bodies from freeloading off his command bubble. On top of that, C’tan taking a points hike and a Necrodermal Binding tweak reads like GW trying to rein in the faction’s most obnoxious durability and efficiency plays without rewriting the whole book.

Space Marines

• What changed: Raven Guard timing restriction; multiple unit points shift; datasheet update noted.
• Verdict: Nerf
• Official ref: Balance Dataslate v3.2, p23

Raven Guard are specifically targeted in this round as Shadowmark Talon Hunter Instincts gets restricted to your movement phase, which removes several abusive timing loops. Terminator Assault Squads receive an updated datasheet to match their new kit.

Key units like Centurions, Vanguard Vets, Victrix Guard (a lot of people think this isn’t a big enough NERF), and Aethon Shaan go up, while a few others drop to keep variety alive. It is a broad but measured Balance Dataslate pass.  

Balance Dataslate 40k’s Mixed Bag

Chaos Daemons

• What changed: Kairos, Rotigus, and the Lord of Change go up; Shalaxi and the Keeper get cheaper; Endless Gift changes to a 5+ version.
• Verdict: Mixed

Kairos, Rotigus, and the Lord of Change pay more for their impact, while Shalaxi and the Keeper become budget threats with real bite. Endless Gift tones down to a 5+ version, which keeps the upgrade interesting without being oppressive.

Drukhari

• What changed: Ravager gets a five-point buff; Reavers see a ten-point buff at six models.
• Verdict: Mixed
• Official ref: Balance Dataslate v3.2, p14

Only slight changes (Ravager gets a 5-point buff and Reavers see a ten-point buff at six models) since the faction is still under observation after its codex release. The developers are clearly watching performance before making heavy moves. This is a wait-and-see 40k Balance Dataslate adjustment cycle for them.

World Eaters

• What changed: Goremongers and Angron drop; Juggernaut Lords and Slaughterbound go up.
• Verdict: Mixed
• Official ref: Balance Dataslate v3.2, p29

Goremongers and Angron drop, which encourages the faction to return to its roots of smashing everything with violent speed. Both changes make the army hit harder and sooner, which is perfect for their identity. Juggernaut Lords and Slaughterbound step up in cost, which keeps the overall power level stable. 

FAQ: 40k Balance Dataslate

What is the 40k balance dataslate?

It’s Games Workshop’s official “live update” document that adjusts rules interactions and clarifies how things are meant to work in 10th Edition 40k, alongside points updates in the Munitorum Field Manual.

Where do I download the Warhammer 40k balance dataslate?

The official download is hosted on Warhammer Community. The current download link is included at the top of the Quick Reference section.

Does the balance dataslate change points?

The dataslate focuses on rules updates, while points changes are handled in the Munitorum Field Manual.

When is the next 40k balance dataslate expected?

The current expectation from players is that the next balance dataslate will land after the release of 11th edition 40k in June 2026.

How should I use these updates in casual games?

If your group wants smoother games and fewer rules arguments, using the current dataslate and points is usually the easiest path. If you prefer “printed book only,” just agree on it before the dice hit the table.

Do all factions get changes every dataslate?

Nope. Not every faction gets touched every time, and honestly, “no change” can be the best change. If your faction shows up in the dataslate but there’s nothing meaningful adjusted, that’s basically GW saying “we looked at you, and you’re not the problem right now.” If your faction isn’t listed at all, it usually means there were no amendments worth publishing for it in that pass.

How do I tell what text changed?

In the official PDF, GW makes it pretty easy to spot edits. New or revised wording is shown in red text, and highlights are used to flag earlier revisions inside the document. So if you want the exact “what changed since last time” answer, skip the vibes, open the PDF, and follow the red like it’s a trail of hobby glue on your desk.

Warhammer 40k Balance Dataslate: Final Thoughts From Us

Overall, the 40k Balance Dataslate keeps shaking things up, and this round proves no army is safe from a good old-fashioned points increase. Some factions are cashing in on discounts, others are footing the bill, and everyone has new tech to test. 

If you’re already wondering “When is the next 40k balance dataslate?”, well, there may not be one till after the release of 11th edition in June 2026. 

If you missed it up top, version notes and the official download link are in Quick Reference. But for now, grab the new 40k rules update, rebuild your 2,000 points, and run some practice games until the muscle memory clicks.
