so im kind of interested in chaos but my love of the primaris models keep stearing me towards loyalist.
do you think it would be too much of an issue using primaris as legionaries?
would you smash my minis if i out them on the table?

I've been tempted to convert some Leviathan marines for the dark powers. I think if done well it could be really cool. Even just a head swap and some spikes might be enough. Iron warriors or Alpha Legion might have an easier time of it.

You mean straight or lookin, chaosafied? If the latter than what the difference outside of the wired mm or 2 of hight?

Are chaos on the same size bases now? I haven’t buy a chaos marine in years.

But can model some up and if someone complained you just pull out your space marine list.
Or just use the marine list to represent them on the battlefield all the time is easy enough.

Just say theyre from a renegade chapter, ezpz

My flamer Marines from Leviathan are now sporting Rubric heads and a Thousand Son colour scheme. They look awesome and no one cares.

I have an Emperor's Children army based on Primaris. I've not had any complaints. I mainly did it because I really hate the spikey trim-heavy CSM look. Going with non-CSM models will probably allow you to make the army more your own, which I can't see anyone complaining about.

As long as you made clear what it was you were using them as with appropriate wargear.

thanks all... i kind of figured it would be ok but i figured i'd bounce it off of you guys.

The only caveat I'd mention is that you'll want to run it bye the tournament organizer if you ever take it to competitive events.

But if you brought spikey primaris models to the table and told me they were chaos marines, I'd have zero issue with it.

FWIW, I use primaris models and rules for my Alpha Legion because imperial rules frequently feel like a better fit for stealthy guys with human specialists than the chaos rules do.

I’d 100% encourage it.

There are only khorn worshiping primaris, but there are no rules for them. So while lore wise it makes sense, am not sure how they would end up being used in the game.

Your figures. Do what you want ....

That said, the tournament advice above is wise.

Make them cool and people will encourage not moan (ok, mostly...)

I’d prefer it if they established some canon that mean that primaris who allowed chaos to touch their soul turned into something more than a chaos marine. Like an obliterator but something different. I personal prefer that CSM are old marines

Disagrees with mrFickle on primaris ---> obliterator... too easy to lose track....

also, chaos is still working.. sooner or later numarines will go to the dark side too....

It would be a bit weird if every single primaris that turned to chaos increased in size and went obliterator-y.

Primaris marines are just the truescale marines we all wanted but with awkward lore smeared on top. As time goes on, GW seems to get closer and closer to just consolidating old marine and numarine datasheets together. So having primaris marines fall to chaos in the same way that non-primaris marines do would just be smoother.

You can always have your own chaos marines be exclusively obliterators and possessed and so forth if that's your jam though. Maybe the primaris from a specific chapter all turn into jumbo-sized chaos weirdos due to geneseed tampering or whatever.

To be fair I said something like obliterators, just my lack of imagination. I think I will just find it boring to have primaris translated to CSM as primaris with spikes. There needs to be something thrown into the mix.

Maybe cawl spent 10k years making primaris because he couldn’t do it, so he used a bit of warp magic to finish the job so when primaris turn to chaos they go demonkin really quickly.

As long as the opponent knows what he's up against i don't see a problem, in fact I'd love to play against it.

I'd like to play through a narrative Crusade story of a chapter's fall. I think there were Crusade rules surrounding corruption- it would have been during the Nachmund camapign cycle with wars of faith. WD did a 4-issue series for both holy and unholy armies.

We've always houseruled promotions... So a unit champion can become a Lord, a unit of CSM can become Chosen/ Possessed, etc.

Just wait til the unit to be transformed hits a limit break, and if your supply limit is high enough to include the new unit, pay an RP to swap the units instead of taking a battle honour. We've had players keep Battle Honours from their previous datasheet too, but you'd have to run that through a GM, otherwise it'll just get exploited by TFG.

I'd be less "interested" in a mix'n'match setup with some Primaris rules, then some normal Chaos rules. If you convert Primaris minis (using Chaos rules), or just make an Ultima Founding chapter that went to chaos (Basic SM Rules with Chaos names for other wise identical rules/abilities) that works.

"Would you look at that, Chaos looted some Mk.X armor!"

(Boom. Done. No smashing of minis or inane lore arguments required. Also then you can have fun putting spikes on Primaris minis.)

Yeah just make them nice and chaosy.

Wouldnt bother me as long as the list is either full CSM or full Marines. No mixing and matching rules/units.

From a modelling pov then as long as its clear whats what I wouldnt see a problem. Would probably look cool.

Reminds me of this guy once had a dual purpose Marine army that were really dark colour scheme with lots of skulls that depending on who he was playing against could be Chaos or Loyalists. He simply had different leaders for squads and HQs and would swap them out to be either or. When asked why he just didnt do 2 different armies he simply said he wouldnt ever do 2 lots of tanks with different paint jobs so was getting his monies worth. Was pretty cool because he had his Chaos characters be corrupted versions of the Marine characters.

Do you think chaos primaris would use something more advance than sticks to decorate their armour

In the HH novels the WE and DG are depicted as being 'embiggened' relative to loyalist astartes. Suggesting a connection to their patron deity/the warp.

Its not difficult to imagine larger chaos marine forms being found in battle in the 41st millennium.

You could argue that the Thousand Sons could 'magically' increase their size to instil fear/awe/contain magiks etc.

The Emperors Children might appreciate improved girthiness....They have a whole lot of pleasure to give eh?

Go for it! Personally, I find a lot of the existing CSM minis fugly and have thought that if I ever made a CSM army myself, I'd kitbash it from 100% loyalist base models anyway.

Ain't no reason why the four powers couldn't corrupt Primaris either, so it's all good

Same, I have a few test models I'm working on for an Alpha Legion primaris force. I'm planning to use the plain and studded shoulderpads from Mk VI marines with minimal iconography, really lean into the idea that Cawl may have used some traitor geneseed without permission.

Ah alpha legion
A good and bad force all in one 😁
Funnily i had the same idea

Hell yes, as someone not into new lore because it is too bright it could even things a bit and set it back to the really grim and hopeless imperium ans thus setting that once was.

Eh, but Alpha Legion rolls with CSM warbands and stuff. Seems weird.
