Hi guys!
I just want to put my two cents in for the ridiculous discussions here on the x-wing rules forums.
While some of them have been productive, most of the ones I've seen tend to never matter or only matter in one instance.
FFG has actually pre-determined how to handle a rules dispute
Roll your defense die and the person with the most focus wins the dispute.
I want to remind people that this isn't magic, and there isn't a stack. However there is turn advancement, and moving from one part of your characters turn to the next would negate any remaining opportunities (such as the ptl advance sensor movement)
Sensor Jammer is a good place to start for this type of issue
Attacker hits with 1 crit two blanks.
Since sensor jammer only affects hits, it cannot take effect and misses his modify attack die step
Attacker Modifies attack die via target lock
Attacker hits with 1 crit and 1 hit
-there is no step afterward to use sensor jammer since you have advanced past the defender modifies attack die
Immediate timing
The immediate is there for a defining reason, to say that you must immediately do this after this
The reason it is not on all cards is that during certain opportunities there is no room between the events going on, remember there are no interrupt spells.
Remember that everything has a timing slot here in this game.
