"Pungency" is ok. I would agree with a range limit. Does that 100 ft range work for you?
Could you write a proposed Net entry?
That Pungency is ok.
I also like the first version of the Immobilizing Net. I have to confess that I am puzzled by the "allt" in Net #2. I can't find a reference to that monster anywhere (or an "alit" or "allit" except as a mis-spelling of "allip"). But is the intent that an ability similar to freedom of movement should free the victim?
Ahh, ok.
What about a DC 20 Str or Use Rope check for the ally?
Yes, looks good to me!
Linked equipment sounds fine and fairly standard. In fact, wouldn't the normal thing to do be putting a line in each of the crook and net descriptions?
Sure, we can add the armor too.
Does "Death Before Betrayal" require anything more specific, like saying a bielgorad that fails a Will save vs a mind-controlling power (from a list??) dies?
