Preferrably a cannon. Maybe the cannon could be a sort of catapult upgrade, requiring 3 smithing, 4 engineering, and 2 chemistry. The crafting recipe would be Plank + Plank + Plank + Gunpowder + Iron + Iron. It's basically a catapult with a few other attributes. First, it would face horizontally instead of diagonally like the catapult, so you know what you can hit and what you can't.Secondly, you can't just put anyhing in the cannon. The cannon has a 3x3 opening in the top back of the barrel where you can put in ammo. When ammo is put in, you have a button which you press to close the hatch. Finally, the cannon doesn't spotaneously fire at anyone's whim. It would have a fuse (that can't be fireproofed but can be put out), and when the fuse burns (it has a 100% chance of burning with all lighters), the cannon would close the ammo hatch if it hasn't been closed already, and explode in the back, which, while doing no damage to the cannon, would send the ammo flying. Then you would have to craft a new fuse and craft it with the back of the cannon in order to use it again. The cannon would have a preferred ammo, such as a cannonball (2 iron, create item). If a cannonball is put inside a cannon (which cannot be done manually since it is bigger then the hatch, and can only be put in if it is crafted with the back of the cannon akin to the process of adding a new fuse), It will create an explosion when it hits a target. We ain't talkin' wimpy explosions here, we're talking explosions that tear through medieval walls like tissue paper and bring medieval houses to their foundations. It would hit with such force that a person on plateau who got hit would fly all the way to bento. May seem a bit overpowered, but consider what you have to do to get it.
