Tactical Weapon Fusion
(from Starfinder Pact Worlds)
You can add the tactical fusion only to a ranged weapon. Tactical weapons are traditionally associated with the mercenaries and the close bonds they often form with one another. Such weapons typically take on decorations of crossed blades, bundles of arrows, or similar sets of weaponry. When you use a tactical weapon to provide covering fire or harrying fire, the bonus granted increases by 1. This ability of this fusion doesn’t stack with other abilities that increase the bonuses provided by covering fire or harrying fire.
