Renegade Traits
As you probably already know, when choosing a Chaos Space Marines army, you can choose for everyone in the army to have a keyword, which allows them to benefit from distinct and powerful new abilities. Now, instead of the Renegade Chapters trait from the codex, you can pick from one of six Renegade Traits. Each is designed around the unique methods of war pioneered by the respective Renegade Chapter it represents. Take the Crimson Slaughter – these warriors are constantly haunted by sinister spirits, rewarded with silence only after slaying their foes. In-game, this translates into a useful Renegade Trait that rewards you with Command Points for destroying a unit.
Or the Red Corsairs! These guys are perhaps the most notorious of the Renegade Chapters, renowned for their vast numbers and superb tactical skill. This is represented in the rules by the ability to Advance and charge, as well as additional Command Points.
These traits are thematic, fun and powerful, allowing you to better represent your favourite army from the lore on the tabletop, and opening up new army builds you might not have tried before. As well as the Red Corsairs and the Crimson Slaughter, you’ll find Renegade Traits for The Purge, Flawless Host, Brazen Beasts, and The Scourged.
Stratagems
It’s not just Renegade Traits – each Renegade Chapter also has their own Stratagem, offering you more tactical depth and more ways to unleash mayhem! The Purge, for example, are notorious for their contemptuous attitude towards life, even by the standards of Chaos Space Marines, represented in-game by a Stratagem that lets them shoot into combat.
The sinister pre-cognisant skills of the Scourged, meanwhile, are represented by a Stratagem that lets them intercept pesky reinforcements with a devastating fusillade of fire.
Warlord Traits
The new rules for Renegade Chapters give you yet more options when customising your Chaos Characters, with a swathe of Warlord Traits. The Brazen Beasts’ Khorne-given might is represented by a Warlord Trait that gives them an extra 2 Strength and Attacks every time they slay a Character. Grab a Daemon Prince, hunt a couple of enemy heroes, and you’ll be nigh on unstoppable!
Looking for something more cunning? Warlords hailing from The Scourged can shut down enemies by forcing them to fight at the end of the Fight phase, after your own troops have had a chance to soften them up!
Artefacts
Lastly, each Renegade Chapter gets their own artefact, allowing you to further customise your Chaos Lords, Sorcerers, Masters of Possession and other war leaders. The Flawless Host’s Flawless Cloak (these guys sure hate flaws!) is fantastic for maximising the range of key aura abilities. The extra attack is pretty nifty, too!
If you prefer to lead from the back, the Red Corsairs’ Maelstrom’s Bite is ideal. Equip this on a Chaos Lord, and you’ll be able to support your units of Havocs, Obliterators and Chaos Predators with deadly fusillades of infantry-shredding firepower.
The Fallen
Vigilus Ablaze includes loads of content for fans of the Fallen, too! As well as taking a pivotal role in the plot of the story on Vigilus, they can also be fielded with the Fallen Angels Specialist Detachment. This Specialist Detachment lets you give Chaos Sorcerers and Rhinos the Fallen keyword, adding yet more flexibility to these mysterious warriors.
This Specialist Detachment is fantastic for messing with your foe’s Command Points, preventing them from generating new ones mid-game, representing Cypher’s disruptive effects on the battlefield…
What’s more, Fallen in this Detachment are particularly hard to hit thanks to an invaluable Stratagem.
Whether you’re using them as an army in their own right, or as allies to a wider Chaos force, the Fallen are as effective on the battlefield as they are inscrutable…
