As you grow more familiar with the rules, you will probably want to change or tweak some of them, and that’s perfectly fine. Nothing in this book was written to be set in stone, but to be a functional game, whose components interact with each other and work together to bring an epic, heroic and fantastic tale to your gaming table. Because of this, make sure to think carefully about the changes you make: they might influence a greater number of elements than what you had anticipated. To make life easier, the book includes a variety of optional rules that can be used to safely customize your play experience.
Needless to say, whenever you want to change something, make sure to discuss it with your game group: you shouldn’t change anything unless everyone agrees.
