Your guide to the latest Warhammer 40k Balance Dataslate 10th Edition Update, including points changes from 2024 through June 2025.
Updated on June 4th, 2025, by Rob Baer with the latest points and Balance Dataslate updates from Games Workshop.
Whether you’re looking for the latest winners to celebrate or the losers to commiserate, this guide has everything you need to stay ahead of the meta and make the most of these latest updates for Warhammer 40k.
Latest Warhammer 40k Balance Dataslate Update
GW released another 10th Edition Warhammer 40k Balance Dataslate in June 2025, along with updated point changes to the Munitorum Field Manual.
They followed the March 2025 big Daemons update, and new detachments with three more new detachments in June as well.
These changes land like a precision orbital strike—clean, calculated, and with consequences across the board. That being said, it was kind of a tame update overall for most factions so far.
Big Winners & Sad Losers: 40k Rules Updates By Faction
Regardless, the latest Warhammer 40k Balance Dataslate updates are here, and as always, they will shake things up across the battlefield. Let’s break down the biggest winners, the units that took a hit, and what it all means for your next game.
Winners
- Adepta Sororitas have a lot to celebrate. The revamped Champions of Faith Detachment gives players more room to experiment without getting punished for creativity. Pair that with a handful of points cuts and some long-overdue buffs to less-used units, and Sisters are shaping up to be a surprise contender. Don’t be shocked when they start popping up near the top tables again.
- Drukhari’s wager system finally feels like a gamble worth taking. The Reaper’s Wager Detachment now rewards both winners and losers of the wager mechanic, which adds some depth to a faction that often felt too feast-or-famine. Expect clever list builders to wring more out of this than we’ve seen in the past few months, especially with the points drops as well.
- T’au Empire saw one of the biggest rewires. The Observer system now works more intuitively—if you shoot at an observed unit, you’re guided. No need for mental gymnastics. Combined with datasheet adjustments across the army, this could be what finally lifts T’au lists out of the mid-table.
- Leagues of Votann got a “quality of life” change that actually matters. Attendants for characters like the Grimnyr no longer eat transport slots, meaning cleaner list construction and fewer movement headaches. It’s not flashy, but it makes running these units less frustrating.
- Blood Angels have more reasons to play their own toys again. Death Company units are cheaper and easier to support, which gives them a stronger identity apart from vanilla Marines. There’s still a slight weirdness with the Death Company Captain disabling his own aura, but overall, the tradeoff seems worth it for players looking to bring more flavor back into their lists.
- Chaos Space Marines are on the upswing too. Daemon Princes got the Lone Operative treatment, giving them more board presence without becoming liabilities. Updates to Lord Discordant and Vashtorr also suggest the faction’s unique characters are finally catching up to their narrative hype.
Warhammer 40k Balance Dataslate: Losers
- Aeldari, especially those leaning hard on Devoted of Ynnead, are getting a leash. The Lethal Intent ability has been narrowed, making it less of a hammer in every situation. Aeldari were arguably overperforming before, so this tweak is less a punishment and more of a calibration—but it will sting players who’ve been leaning on that ability too often.
- Space Marines—or more specifically, Ultramarines—took a hit to their Command Point engine. Guilliman’s ability now works once per battle round, and Calgar only brings his CP regen if he’s your Warlord. The popular combo of “infinite CP” just got a lot more finite.
- Tyranids didn’t walk away unscathed either. Hive Tyrants have to pace themselves now that Will of the Hive Mind is limited to once per battle round. That’s not a death sentence, but it does slow down some of the faction’s strongest plays. On the flip side, Psychophages got a glow-up, so there’s a consolation prize in the mix.
Mixed Bag
- Astra Militarum saw a lot of shifting numbers on the spreadsheet—points going up and down depending on the unit—but the biggest functional change is that Lord Solar Leontus can now issue orders to Titanic units. That’s a subtle but powerful option for players running super-heavies. It won’t change every list, but it opens a door that was firmly shut before.
- Orks are speeding toward relevance at breakneck pace. With Speed Freeks units getting points reductions and their Adrenaline Junkies Detachment delivering faster, scarier charges, green tide lists just got a major injection of tempo. It’s fast, it’s fun, and it hits harder than you’d expect. However, they did get quite a few point NERFS, so it’s a bit of a mixed bag here.
40k Munitorium Field Manual Points Updates Across Factions
One of the most eagerly anticipated aspects of any 10th Edition Warhammer 40k Balance Update (from 2024, or 2025), are the changes to the points. These adjustments can dramatically alter how armies are built and perform on the battlefield.
The rationale for these 40k points changes is to promote fairness and balance in the game. Units that were previously undercosted and thus overly popular have seen point increases to curb their prevalence and power.
Conversely, units that were less effective or underused have had their points reduced, making them more attractive choices for players. You can read more in our Munitorum Field Manual changes article, which breaks down each faction in detail.
