Info:
Armoury / Missile Weapons
This is the ability to build, modify, and repair a specific class of weapons or armor. (It does not include skill at design; for that, see Engineer)
A successful roll lets you find a problem, if it isn’t obvious; a second roll lets you repair it. Time required is up to the GM. You must specialize in one field:
Missile Weapons:
Man-portable, projectile weapons of all kinds – bows, crossbows, slings, etc.
