I appreciate the response greatly! Its super helpful to hear what the intent behind design choices are, should help me a lot in the approach to this.
Understandable how some stuff can get lost in the time pressure with stuff like the Theletus agnosia etc., I will try and follow that idea and come up with a factionwide agnosia! Can imagine slotting in a 'drowzy' form for all of them and I have some time before my players fight them to figure it out!
I look forward to anything more that gets put out for HELLPIERCERS whether that's updates to the book or any extra stuff!
