Other Actions in Starship Combat
While your role determines what actions you can take during a starship combat encounter, on occasion you might want to perform some other kind of action, such as casting a spell or using a class feature. The GM has the final say on what kind of regular actions you can take, but generally, you can take only a move or standard action in a single round, and you can take only a minor crew action (see page 326) during that round. You aren’t assumed to be adjacent to any of your allies during starship combat, so the GM might also decide that you need to take an additional round to get close enough to an ally to affect him with an ability or spell. Any such action is resolved at the beginning of the round, before the engineering phase.
