Weapon Proficiency
Wretched Hives · Equipment
Your species, class, and feats can grant you proficiency with certain weapons or categories of weapons. The three types of weapons—blaster, lightweapon, and vibroweapon, are further broken down into two categories—simple and martial. Proficiency with a weapon allows you to add your proficiency bonus to the attack roll for any attack you make with that weapon. If you make an attack roll using a weapon with which you lack proficiency, you do not add your proficiency bonus to the attack roll.
Proficiency in these weapons is discussed further in Chapter 6.
