Gunsmith

Effect

Resource cost: 1 hour + materials (Cost Rating 2, approximately §11–50).

During Downtime, you can perform one of the following modifications to a firearm:

• Tune: The weapon gains +1 Roll Bonus for its next 3 uses (shots or melee strikes), then the bonus fades. Represents fresh oiling, sight adjustment, and spring tightening.
• Reinforce: The weapon cannot Jam from Fumble effects for the next session.
• Customize: Fit the weapon to a specific user’s hands, stance, and eye. This grants the +1 Signature Weapon Roll Bonus to that specific user for that weapon. This is an alternate path to the Signature Weapon talent’s +1 — it produces the same mechanical bonus through craft rather than bond.

Limit

A weapon can only have one active modification at a time. Customize replaces the need for the Signature Weapon talent for that weapon — the bonuses do not stack (still +1 total).
