Are there any guidelines or would people be interested in sharing their thoughts on how they’re putting together these monsters? Might is fairly straightforwardly covered in the text, but what about Nature? What makes you chose a high or low nature for a creature and how high? What’s guiding you when setting disposition levels?
Well, I found the Disposition breakdown in the rules. So never mind on that front.
Now that the PDF is out, I’d use the monsters in the book as examples and build off them.
