Just want to know if I'm thinking about this correctly. If I equip Vader (2 actions) with Deadeye (Can spend focus instead of Target Lock) and some missiles, and he both locks on to an enemy ship and focuses on his action step, could I then spend his focus to fire missiles, and reroll any dice by spending the Target Lock?
Also, if that is a legal move, would the better order be to burn the lock firing missiles and use focus on the resulting roll?
