More Starfinder!  Feats!

SLOW AIM (COMBAT)

You only need one shot or swing if you hit the target

Benefit: When you make only one attack in a turn, you gain a +2 bonus on that attack roll.  You can make attacks of opportunity after your round and still gain the bonus of this feat.  If you are granted another attack by an ability or feat like cleave, you may make that attack without the bonus from this feat.
