Ok hear me out
Rat Ogre Variant:
Blade Hand
Bone Breaker (Maybe could cause tremor)
PackMaster Variant:
Warpstone Probe (Moulder Agitator)

Whip (Vermin master)

I could see the Moulder Agitator run as does the PackMaster then stab toward the Hero chocking them (Like Tazer in Payday but for a more limited time)
Vermin master could buff Skaven Slave and Clan Rat but would deal dmg on each hit
Blade Hand would be a weaker but faster Rat Ogre while the Bone Breaker would stronger but slower
That rat with the whip would be an AWESOME addition.
Mostly because of the sound design guys could work on a different sound effect for the crack of his whip, similar to the critical effect that renders the game audio off pitch for a second (wich i love)
his whip attack could have a slight half second of silence if he cracks it too close to your head and by the time the audio goes back you can hear his laughter.
It would be funny if the skavens gonna die by does whippings. ※No mocking or else. I really think it would be funny in positive way
Honestly I see no reason for this. These enemies already have so little HP that either they are killed outright or the damage they take makes pretty much no difference. Better then to have it as an aesthetic effect but without a mechanical impact in regards to the Vermin Master whipping the Skaven.
Does Clan Moulder/Skryre make explosive rat ? Like they could spot the Heroes and start running toward them and on a timer would explode
Suddenly getting massive dejavu from season 1 weaves here …
