Wait, you mean actually KILLING his friends? Like you do damage to the other NPCs and they don't go into combat mode? Because when I messed around in release 1 with the final battle and barrels, that wasn't the case at all, and attacking the other NPCs would trigger full combat.
They go into combat mode, but the boss doesn't if he is in TALK-LOCK. Meaning you can slaughter his henchman without him being part of the battle because he is frozen in the talk.
