Blood Knights and the Unstable special rule

[Fluplar5]

Hello fellow Druchii players

I have a question about models with the vampiric special rule and the undead special rule.

If a unit of Blood Knights, which are undead and also have the Vampiric special rule, are beaten in CC, do they still suffer an extra wound per point that they lost the combat by due to them having the unstable rule because they are undead.

if anyone out there has an answer or an idea please leave a comment.

thanks

all that rules does is that they do not crumble if the general is killed.

... even the Vampire Counts general will crumble to CR
