Winter Core Flintlock Pistol Designs

Flintlock weapon designs for a personal project.
The flintlocks are intended to be player crafted weapons which are infused with frost magic. Because the 'winter core' used to power those pistols is not fully compatible with the mechanical designs, this causes the weapons to freeze up over time if they are inactive. This grants the player the ability to use a stronger charged attack if they haven't used them for a while.
