from the introduction:
You won’t find the basic rules of Dragon Age RPG in here. This is an expansion to the original game, that takes the AGE mechanics and puts it into the Mass Effect universe. You will find new rules or rule adaptions (like the Health/Armor/Shield mechanic for example) new classes, talents, Biotic and Tech abilities, items and adversaries. You will find new focuses, but you won’t find an explanation about focuses in general, what bonuses they give or how they work exactly. You won’t find rules for basic, opposed and advanced ability tests or combat mechanics. You will find new stunts, but I will not enlighten you on how to generate and use stunt points. All of those rules are included in Dragon Age RPG Set 1.
