Now, let’s jump into the new rules!

New 40k Ad Mech Detachments & Codex Rules

The new Adeptus Mechanicus 40k Detachment and Codex Rules are from Warhammer Community.

First, there are five different detachments in the codex:

Rad-zone Cohort – Current detachment, but GW says the rules will get better (and a stronger Rad Bombardment)
Explorator Maniple – Get bonuses while close to an objective (more below)
Cohort Cybernetica – If you love big blobs of Kastelan Robots, this will power them up!
Data-psalm Conclave – Will have a big focus on your Tech Priests.
Skitarii Hunter Cohort – This looks to focus on Skitarii (detachment rules below), and the detachment rule gives them much more survivability.

Explorator Maniples 10th Edition 40k Detachment Rules

You get re-rolls for Wound rolls of 1 when safeguarding or clearing out your chosen objective, but that’s not the only benefit of designating an Acquisition objective marker. Your Enhancements synergise perfectly with the Detachment rule – a skilled Genetor gives their entire unit a formidable invulnerable save while defending their prize.

If you can get a bunch of your units around a single objective (or your opponent bunches around an objective) getting to re-roll all your wounds is super strong!

Especially if you also buff up your hits, you’ll get rerolls for all shooting and melee. Then, if you also have the Enhancement, you’ll get a 4+ save for your unit! A unit of six Breachers with both of these will be hard to remove and hit extremely hard.

The Explorator Maniple’s Stratagems likewise work with objectives. Are violent intruders threatening your precious loot carefully-excavated samples? Trigger a Reactive Safeguard and leap back inside a nearby TRANSPORT to make a clean getaway preserve the Omnissiah’s inheritance. Even if your valiant defenders fall to enemy fire, Cached Acquisition of their data-logs will ensure you keep hold of the objective.

The jumping back into the transport is really interesting, and it’s a little unclear what happens if the enemy doesn’t also declare against the transport.

Does their charge automatically fail? Hopefully, we’ll have some clarification on that. Still, it’s a really cool rule and can save you from a giant charge!

Cached Acquisition will be great for keeping the backfield objectives that you get shot off without having to run units back to it.

Cohort Cybernetica Detachment Rules

Advanced Cyber-psalm Programming provides a simple but effective Detachment bonus, giving LEGIO CYBERNETICA units access to your Doctrina Imperatives army rule. This returns unchanged from the faction’s Index, allowing you to make your robots tougher and more accurate when defending, or deadlier and more agile on the attack.

While this isn’t the most exciting of detachment rule, being able to get all the doctrines is strong and can give you a lot of buffs.

Enhancements and Stratagems are where the real magic happens. Would you like to shrug off the blast of a volcano cannon as if it were a mere lasgun, once every round? Call the Necromechanic. Lazy and sullen machine spirits refusing to erupt in sacred fire and take their enemies with them when the strength and certainty of steel fails? A spot of Emotionless Clarity will teach them (and anyone nearby) the error of their ways.

Necromechanic is honestly just an exceptional ability! As once per battle round, you can just shrug off basically anything! This adds a crazy amount of survivability to your army.

Emotionless Clarity is also super fun! Who doesn’t love the idea of just always blowing up when you want and dealing a bunch of mortals wounds?

Access to the Protector Imperative also gels brilliantly with the new Auto-Divinatory Targeting Stratagem. The bonus to Hit rolls granted by the [Heavy] ability wouldn’t normally stack with other Hit roll modifiers… but this Stratagem directly changes the Ballistic Skill characteristic of your tanks and automata to 3+, so you can benefit from both at once.

If you combine this with the heavy ability (and don’t move), you’ll hit on 2’s for just one CP!

Skitarii Hunter Cohort Rules

On top of that, the existing Rad-zone Cohort receives revisions increasing the efficacy of its Rad Bombardment, and the new Explorator Maniple sets its sights on acquiring rare archeotech from the battlefield, no matter the cost. The Cohort Cybernetica provides you with seriously powered-up Kastelan Robots, while the Tech-priests of the Data-psalm Conclave exhort the Cult Mechanicus to eradicate their foes.

You can give huge swathes of your army stealth and the benefit of cover! When you add this with the better save, they get a 3+ when your opponent is more than 12″ away!

Once your army has tiptoed into position,Binharic Offencelets two SKITARIIunits attack a prime target with unthinking synchronicity, their lockstep assault improving their Armour Penetration by 1. Pin down an enemy with a Skatros sniper, then blast through their vulnerable spots with aS korpius Disintegratoror a squad of Rangers.

If you have two big units with a ton of shots, this is really powerful, too. We’ll see if they have any ways to generate extra CP because they already have a few 2 CP strats that may end up being pretty draining…

Adeptus Mechanicus 10th Edition 40k Rules: Datasheets & Index Cards: (June 23, 2023)

The new rules come from Warhammer Community.

Doctrina Imperatives let you adapt to the enemy battle plan either by shoring up your defences early on, or going for a knockout blow against a foe playing too safe.

These are much simpler than currently, as there are only two options; from the looks of it, you just pick which one you want. First, you can either worsen your opponent’s AP and gain the heavy ability or turn your weapons to assault and improve your AP by one.

To further coax an entrenched opponent out of their comfort zone, Rad-Cohort Detachments turn their deadly radioactive weaponry against entire sectors of the battlefield. A heavy pre-battle Rad-bombardment is the perfect way to throw plans into disarray and deny backline objectives, as the fallout punishes anyone who thinks they’ll be safe holding the fort.

This is pretty wild because if they are battle-shocked, their OC goes to 0, so they don’t actually capture objectives. Then if they decide not to take cover, they can pretty easily suffer D3 mortals. Then, you can cause Mortals to the enemies the rest of the game, and if they have a lot of units sitting back, this can rack up the damage on them.

New 10th Edition Warhammer 40k Adeptus Mechanicus Datasheets

As Battleline squads, you can take twice as many Skitarii Vanguard and Rangers as other units in your army, but the benefits don’t stop there. Several other Adeptus Mechanicus units have abilities that improve when they’re near their Battleline comrades – such as Sicarian Ruststalkers, who double their bonus to movement and charge distances from Optimised Gait. This gives Adeptus Mechanicus infantry the feeling of a well-oiled machine.

Well, their save all-around is getting much worse, and their BS is going to 4+, but maybe the Doctrinas will make up for it.

Next, they ignore enemy cover, make vehicles have fewer OC, and can regain your Command Points. For weapons, the Radium Carbine with Anti Infantry 4+ should really help their strength.

From the looks of this, Vanguard and Rangers will actually make the rest of your units better, so maybe that’s why they made their stats weaker.

This synergy is the brainchild of the vaunted Tech-priests, and none have had quite as much impact in recent times as Belisarius Cawl. Putting aside his 10,000-year project to create the Primaris Space Marines, he’s a phenomenal battlefield commander, and can adapt to lead his phalanxes to victory.

Cawl now has a lot of wounds, high toughness, and a great save. His weapons are decent, but his real strength seems to bome in from his auras. First, he can either give re-rolls for hits or battle-shock tests. Lastly, he can give out stealth.

Then, he self-repairs and counts as a lone operative (and we’re sure he can repair as a tech priest).

New Weapon Rules

One such weapon is the Eradication Beamer – a large directed energy weapon mounted on the Onager Dunecrawler. While its raw statistics are largely similar to its previous incarnation, the addition of Sustained Hits D3 piles on plenty of extra attacks when the blast hits its mark.

This is interesting, as most weapons have gained way more strength; however, with sustained hits D3, you can actually get a ton of shots for this. If you get lucky and roll 2 6’s, you can actually get an insane number of shots off.

New Adeptus Mechanicus Warhammer 40k Stratagems

Stratagems further reinforce these deadly technologies, amping up the power of weapons and bombarding vulnerable objectives. In particular, two Stratagems further enhance the Doctrina Imperatives army rule by granting powerful effects only usable in one mode or the other.

This is actually pretty huge for combat armies, as getting to advance and charge with your whole army for only 1 CP is great.

Aggressor Imperative goes all-in on a headlong assault into enemy lines, following up a barrage from your Assault weapons by charging full-speed into close combat. Likewise, Bulwark Imperative shores up a critical unit’s defences even further, turning Vanguard and Rangers into immovable objects even as they lay down fusillades of disciplined fire.

Getting a 4+ invulnerable save is awesome, as the save for most will probably be down to a 6+ invulnerable save with the new datasheets from the looks of it.
