You hone your weapon training to focus on long-range fighting. You become proficient with sniper rifles and linear fusion rifles, and lose proficiency with all other weapons except simple melee weapons. Due to your sheer dedication to the craft, you cannot gain proficiency with any weapons that aren’t a simple melee weapon or a long-range weapon.

Furthermore, once on your turn, before you make an attack roll with a shot from a long-range weapon, you can choose to take a -6 penalty to the attack roll. If the shot hits, add +10 to the attack’s damage, or +15 if you scored a critical hit.
