Firearm Upgrades

Anyone tinkering with firearms might find themselves wanting to upgrade them to serve certain functions. Upgrading firearms may be done as an upgrade using the Armorer's Handbook weapon upgrade system. Firearm upgrades are 1st-tier tags (base cost 100 gp) that increase the weapon's misfire score by 1.
