I'm playing as a artificer in my friend camp(which have alot of homebrew) and he allow me to craft any magic item/weapon if i have a hand-drawn blueprint. But after looking around for a while i doesnt see anything that like a sniper gun. My first idea is making a gun that can shoot from a long range and i can channel my spell through it. Example is channel fireball spell into the gun and shoot it in a wider range. I hope to receive more ideas, recommendation from you guys on how to make this.
