In the latest preview, "Bound for Adventure, part two", they present the defense value. It is said that you determine your defense score at the same time has soak, strain and wound treshold.
I was wondering how it works ? Is it like defense for ships where it is the shield rating or more like an active defense like lightsaber parry or a bonus from armor ? Maybe from special talents ?
Thanks a lot
A character's (or target's) Defense rating adds Setback (black) dice to attack rolls targeting that character. Your defense is value is primarily determined by your gear (armor, shield generators, etc), not your attributes, so I'm not sure why the say you determine your defense vscore at the same time as soak (relies on Brawn), strain (relies on Willpower) and wound threshold (relies on Brawn). While the Beta text (pg 134) refers to talents that increase melee rating, I can't actually find any that explicitly address "Defense rating", though several (e.g. Marauder's Defensive stance & Scoundrel's Side Step) have the same effect (add setback dice to attacks).
While this makes the target harder to hit, it doesn't increase the "difficulty" of the roll (Simple, Easy, Average, etc). The difficulty of the task (e.g. hit a target at medium range, or doing a back flip) determines the number of Difficulty (purple) dice and is usually constant, though some specific situations (e.g. firing a rifle at an engaged target) may call for increasing difficulty dice.
The wording in some of these sections requires some finesse to really understand.
Hope that helps.
