Okay, the ice bullets are easy. I can either make custom ammunition that has dry ice tips and freeze pellets, or I can create a miniature enchanter that will feed off an (ice) magic generator, and will enchant the bullets to freeze. Of course, either way it would still just be small arms ammunition, so it wouldn't fully freeze upon contact. Instead, it would freeze the area that the bullet penetrated, creating a chunk of ice upon contact. The underbarrel flamethrower however, would be a different matter. Since they are just underbarrel attachments for pistols, I have two options. One is to just give a magazine/drum for the flamethrower itself and make it so that its replaceable. The advantage of this is that you have much more range than the other option, and the stream of fire will be a little bit thicker. The drawback of this is that you will have to carry flammable ammo with you at all times, creating a risk for your ammunition reserves to explode. The other option is to use an arcane generator (like usual) but draw the fire in a more raw manner, converting it to fuel. The advantage of this is that you will not require any reload. But the drawback of this is that range of the flamethrower is decreased by about a meter.
