As a follow up. I guess for an Attach I would actually use d20 + Body (value) + Violence (dice) + Weapon (dice) .... So this could be where I am going wrong and why it was so fatal.
Ok, so to lay it out:
If you want to attack, you roll d20+Body (Value)+Violence(die)+Weapon(die).
You would sum it all up. If the result was higher than your body difficulty, you are successful and deal 1 wound.
I can see where Armor for enemies is unclear (as you'd not want to add the enemy's armor die to the total you rolled. I got a wire crossed somewhere. I'll take a look and clarify in the next updated revision (aiming for this weekend).
To avoid harm, you would roll d20+Body(Value)+Dodging(die) vs Difficulty 17. If you fail, you then roll the armor die. You then get hurt.
