There are a couple of mannish items that I either can’t locate, or they’re not in the BWG book.
Brace of Pistols - This is just cool (and useful, given pistol’s reloading time). I’m thinking 20 rps. Normally a pistol costs 15 rps, so 5 more seems reasonable. What you’re really getting is shortening the reload time to the time it takes you to draw a pistol.
Bombs - How much should some bombs cost? I am thinking of the Iron-Cased bombs described in the Weapons chapter. They are clearly a mannish weapon, but how many rps? They aren’t that powerful weapons in RnC, but once you get close… They should also be fairly rare. I’m thinking 10 rps for 4 bombs. Does that sound reasonable? Perhaps just 3 for 10 rps.
