Be aware the images and info below may be out of date, the most recent version will always be in the 5eTools Collection (See Homebrew).
While there are already firearms in official WOTC source books, I felt that for a setting like The Skies of Caligos, a more in depth system was needed. The below contains several types of firearms and some modifications that can be made to them.
Prices are always variable depending on ingame situation. (e.g. buying on a black market will likely be far more expensive)
