If you check out the Adventures book, you will see how they tweaked the monsters' Ferocity. If you get the Bestiary, the sea serpent is also a good guideline for monsters vs their size.Any advice on building adventures that are balanced so I don't TPK or cake my adventures? Really love this system and want to build a home grown campaign but need GM advice. Been a GM for 35 years but never played a game like this.
