Ops and Tactics: Supply Drop Volume 12 (Magical Weapons and Muzzleloaders)

From the introduction: This book details creating magical weapons such as rods, staves, and wands, as well as imbuing power within muzzleloaders. Cartridge and shell based firearms, because of their complexity, are unable to be enchanted, but the magical community, through various trial and error, found that simple muzzleloading firearms, such as matchlocks and flintlocks, were simple enough for magic to take hold and be used without issues.
