These rules are collected from all the following reviews on YouTube, Imgur, and Warhammer Community alike, so be sure to watch your favorite presenters talk about their take on the book at the links below!

Since this is a little different than a standard faction codex or supplement, we’ve included the introduction below in case you are curious about how exactly the rules are applied to each faction.

New Imperial Guard Cadians 40k Rules: War Zone Octarius

If you can bait your opponent to over commit to one side of the board, then quickly redeploy your biggest threats to the other side (especially long-range threats) you dictate how they have to play their first few turns! The only tricky thing is if this is better than any of their traits available to the greater Astra Militarum forces.
40k Cadia Octarius Relic Rules:

Even with the restriction, this can be extremely powerful, getting you free stratagems every turn can be huge, and easily win the game with the extra power! In this book alone there’s potential to get 2 completely free stratagems over the course of two turns.

Ignoring any modifiers, especially for those giant units, is really nice and can keep those poor conscripts in line. Next, it is pretty strong in combat, and we can imagine some heroic moments with this!

New Octarius 40k Deathwatch Space Marines & Inquisition Rules

While Specialism Extremis seems very picky on the surface, and expensive at 3CP, getting an entire unit to auto wound if they hit can be a massive boost in damage that turn, especially when you get high damage, but low strength attacks going against a high toughness unit.

This makes your already very versatile force into one that can truly turn into the swiss army knife of Space Marine armies. Each Battle round, you can manually select any Space Marine Chapter Tactic from the Core Space Marine Codex, and swap out your Xenos Hunters tactic for it!
That means you can have a huge variety in bonuses depending on what you need at exactly that turn. The only downside is you can’t select any tactic for more than one turn… Even still, this seems super strong!
New Inquisition 40k Rules:

They are more or else exactly the same as they were before inside Psychic Awakening: Pariah, except now they can be paywalled behind the 40k app with the digital code at the back of the book…

Additionally, Fire Points has been upgraded to allow 20 models embarked to shoot instead of the previous 15 and Automated Weapons now prevent the Silo from being fired if no units are embarked. Overall, this looks to be an even trade, perhaps better, assuming you plan on keeping units embarked!
The Skyshield Landing Pad seems to have gotten quite a few rule changes, but ultimately this is just to make the rules more in line with the 9th edition core rules. The big take-aways are that Shielded only provides a 6+ invulnerable save instead of the previous 5+.
Additionally Unfurled now heals the landed aircraft a guaranteed 3 wounds, instead of d3 previously, and even better now regains the ability to use one-use weapons it already used prior to landing! It also gains +1 to hit with ranged attacks for that turn! Overall this is a massive boost in power for this Fortification going all-in on aerial focus and removing its niche invuln rule.

The abilities are brought up to speed with 9th edition rules but largely function the same. This seems to be a great update with CP generation being a huge bonus!

Additionally, to avoid the Automated Weapons restriction rule you now need an Infantry unit within 1″ of it to perform the new Operate Gun Emplacement (action) and it buffs its BS to a 4+. This also seems like a positive change, but still might not be that great overall.

The Skyshield Landing Pad has gone up 20 points while the Bastion went down a whopping 30 points! Finally, the Aegis Defence Line also went up in points with a +15 point bump at base loadout and +10 from previous with the Quad-gun option instead. In general, these changes seem to be mostly positive, but only time will tell.

This is pretty sweet, allowing you to adapt to the game as it goes on. Plus, this is just fun, but it’s something else you’ll have to remember at the start of each battle round. So, you can just wait until you realize you need something and change.

Biomorphic Carapace on the other hand adds a ton of durability to one of your important character models, making them wounded on 4’s most of the time and 5’s a lot of the time depending on the model.


They form a sort of network that increases the normal 12″ of your one Link-equipped model to potentially the whole board (not quite, but a lot more than 12″)!

First Psychic Channeling, look sneakily good. Being able to roll and extra dice and discard one means you’ll be casting much more of your powers on average (from the selected unit). Additionally, if you combine this with the new Void Crown relic, you can get an increasing amount of un-deniable powers!
Second, Bioweapon Bond or Weaponised Gestation, which fill the same role for different types of units, are both good. In short, roll buffs or re-rolls are always strong! It just depends on whether you have more Melee or Ranged threats to target within your list to receive the buff.

Giving the benefits of light and heavy cover all the time, then giving them dense cover over 12″ is really strong. Hopefully, this helps your Genestealers survive long enough to get into combat!

This isn’t the craziest one ever but for 15 points it’s not bad. Maybe they’ll be the codex to really try and take advantage of enemy Morale.
Overall it’s a great time to play 40k as new updates bring renewed life to the game, however with supplement after supplement (not to mention the FAQs, etc.) there is a cost in money and time.
