But not the pendulum's grinding attacks? Or?Lygur’s TongueAll enemy model parts in units in base contact with the bearer suffer -1 Attack Value.
The plague pendulum has several model parts, and each of them suffers -1 AV (i.e. the patriarch and each crew member).
And sorry about the initial question, really, it was because my Army Builder-programme only said "models" and not "model parts". The rules are clear regarding the crew and the patriarch, but I'm slightly in doubt as the grinding attacks. My guess would be that it works on those as well, though?
Attack Value is the attacks you have from your profile.
So Grind is uneffected.
