We recently started playing WHFP in my group and after one session I'm starting to wonder if we understood the Target Defence value right or did we miss something in the rules.
We played so that for monsters Target Defence value is the number next to Agility in parenthesis (usually between 0-2) and for PC's the value is Defence gained from any armor and/or shield they have equipped. Each point of Defence value added a misfortune die to the check vs. Target Defence.
It just seems so easy to succeed in every vs. Target Defence check. A pretty basic fighter character can easily have at the very beginning atleast St 4 + Weapon Skill trained, so it's 4 Skill dices + 1 expertise die vs. 1 challenge die and 0-2 misfortune dices. With those odds it seemed that we never missed Basic Melee attacks.
It would seems logical that Agility value enhances Defence value somehow, but I can't find any mention about it in the rules.
