When it comes to Vorrenius Corosz, is it really intended that he be fielding a retinue of 5 Tech-Assassins (relabeled rebuilt mutants in the scenario) with no modifications whatsoever? That would mean a group of six Masters... the Tech Assassins on their own are capable of making up to ten power blade strikes per round, for instance. It seems wildly disproportionate to the other factions in the mines, who have regular Mutant Devotees and Cult Zealots.

Sure,

Let the lesson be, don't mess with Vorrenius.

I agree. It seems quite clear that f**king with Vorrenius is meant to kill you. So leave it. If your players want to have a go at him, let them feel 60 strikes.
