New Tyranids Faction 40k rules are here from the Warzone Octarius supplement that look to up the bugs’ potential on the tabletop!
With the Warzone Octarius supplement in hobbyists’ hands, we can get a better picture of what all the new rules are looking like for factions focussed on in the book.
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.

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.
