Talking with a friend earlier about Squall's gunblade from Final Fantasy VIII, and how she plans to adapt it into Pathfinder, so it got me thinking of how it might work in Dresden. For those unfamiliar, the Gunblade is mostly sword, with a revolver as a hilt, and when the trigger is pulled, the cartridge inside goes off, the explosion vibrating the blade for extra damage. In the game, you had to time a button press with the character's strike to get the benefit. It's also said in-game that it's very difficult to use properly.
Now, as for replicating this in Dresden, firstly it's probably a Weapon:3 sword just on its own. I was thinking of a stunt for Gunblade Mastery to represent the good timing -- something like, whenever you roll a natural +3, add 2 to the weapon stress.
Thoughts?
