Marksmanship

Marksmanship is one of the twelve major skills, and governs over accuracy when using ranged weapons, and the creation of those weapons and their ammo.

Summary
Marksmanship is a skill based on knowledge of firearms or otherwise ranged weapons, as well as proficiency when using them. Subset abilities include the ability to throw other objects (such as table knives or grenades), as well as the modification of bullets and arrows. Aiming using this skill is linked to Perception, and modifying using this skill is linked to Engineering.

As a master skill, Marksmanship entails heightened aim using a background-specific weapon, as well as expertise and a vast expanse of knowledge on the weapon type. While mastered Marksmanship does increase the success of getting a hit, it does not guarantee hitting the mark every time- but it does make the difference between Marksmanship as a primary master skill and as a secondary master skill.

As a secondary master skill, Marksmanship entails just short of what it does as a primary master skill. Knowledge is slightly more limited, though there is no major gameplay difference other than when faced against a primary Marksman.
