This thread is ambitious asf.
Not to imply that's bad.
To be fair, we have a charm that allows us to succeed at anything we try to escape confinement unless we're opposed by someone with defences against reality warping, and also have an artifact that says we're always trying to escape confinement.
When facing even empowered mortals like chaos warriors, it makes us very, very unfair, in a pretty Ebon Dragon-ish way.
The last thing you want to try and do is trap or imprison an Infernal with CCC, as it massively empowers them.
If we didn't have the tattoos, we'd have to have Lorgar try to save Dhokar, I now realise. Otherwise, they'd just let us go. We'd need them to try to stop us leaving before we could use CCC to try to convert them.
The artifacts mean we don't need to wait, but even without them we could pull off this kind of trick. Converting your jailers to your cause is right in the core use of the charm, it's not a stretch at all. The fact that they're all here in one place and can hear us at once just makes it a better opportunity for us.
I genuinely didn't realise how astonishingly amazing CCC would make us at social combat. We're arguably even better than Lorgar. There can be social challenges too hard for him, or he can just perform below his usual standards. With the third feature of CCC, we can't, we always succeed, no matter how difficult it is.
We'd be absolutely terrifying against worlds with broadcast media or information networks.
We're also a terrifying foe for the Covenant. As we can manufacture loudspeakers, any army they can send against us will rapidly become our army, and once we reach their cities we can convert their population from under them. Even if the priests have Shaping defences to prevent conversion, the rank and file won't.
