I guess I dint know how to think about patriarch resilience, because I the one hand they are incredibly tough, but on the other more than half of them are dead. And something killed them.

On the topic of the game harlequin's kiss . . . It isn't full of "razor wire" or "sharp wire", it's full of mono-filament wire. My recollection of the description is that the wire is a single molecule or atom wide and cuts by passing between the bonds of other atoms/molecules. At least in the old fluff it could basically dice anything it touched armor, flesh, or supernatural being.

I don't know if any of that has changed though.

I'm not really taking a side, I just don't know how to think about patriarch resilience.

A Space Marine's combat knife also has a mono-molecular edge, yet you don't see those chopping through power armour etc like there's nothing there.

Food for thought.

I remain unconvinced.

Primarch skin can deflect bolter rounds. Can a harlequin punch with greater force than that?

Remember too that a primarchs physiology is a mystery to even the apothecaries of the legions, those most familiar with something approaching primarch physiology. They have a unique internal structure only superficially similair to a humans or a space marines.

Ultimately it takes something very special to kill a primarch as they're supernatural beings. Made with warp craft they're largely immune to mundane weapons and effects. The things that have proven lethal to them are other supernatural things; warp powers, deamon weapons, other primarchs.

I don't doubt it would hurt them, but i don't think it would kill them. Aside from all the above there's the fact it's going to be damn difficult to land a hit or penetrate the primarch with the weapon and once the harlequin does the primarch's hardly going to just sit there and let it liquify him. The primarch's going to rip the harlequin's arm off before too much damage is done.

Seeing as how that would not work with at least one primarch, I'd say that is a gross assumption. We don't know who else could be a perpetual or something crazy. The primarchs genetic abilities are a mystery. Fulgrim killed an Avatar which could destroy a lot of Harlequins. The Avatars are the equivalent of a primarch level characters. You're also assuming the biology of a primarch could not heal instantly from internal damage. The only thing we've seen defeat their biology has been warp poison (Horus and Gulliman) and a decapitation (Ferrus Manus and Kurze). Now this weapons seems dangerous but getting through primarch armor, speed, and skill will be dangerous. I don't see a Harlequin getting this done to be real with you. It's the same argument of the Nemesis novel with the Execution force. A Vindicate could kill a primarch, if he got the shot. How likely is that?

Given that Fulgrim survived a sniper's bullet to the brain pan i'm not so sure that's true.

Which of course speaks volumes to a primarch's durability and no doubt miraculous biology.
