It means every single one that attacks you gets a bonus to hit.
I shall clarify the immunity issue. You cannot target anyone at all when dogfighting.
You can target when Hunting, but players are immune to being targetted if there are still enough Mooks to cover them UNLESS they make a manoeuvre that blows that cover.
Ok, Dogfight-a-doodle-do!
Six TIEs are not trying to fight but to go straight past. Your attacks become targetted on them.
Cass rolls a 20, and so can destroy one of them in the most spectacular way imaginable.
Kyle rolls a 16, that is a kill as well.
Eerin can't actually attack the ones going past, but as he rolls a 3 anyway, his fire goes wild.
One squadron (now of 11) goes after Cass, the rest go after the Last Laugh, as does a dogfighting Sqaudron leader.
Ooh, Cass is nearly unscathed, but he actually takes a hit.
Last Laugh is completrely swarmed by nearly two dozen fighters. Kyle is piloting like mad but he is not a one man fleet!
The Squadron Leader comes in exeprtly; Kyle is keeping an eye on him and manages to keep clear of his fire but the criss-crossing green death from elsewhere is too much to avoid!
Four TIEs are past and on the chase.
Scarlet, are you going to help the Smugglers?
