Here's some more homebrew stuff I made for the campaign I'm DMing. It's a pair of rifles that work off of each other, the anti-material and pro(grammable) material rifles. The anti-matter rifle removes a 5-foot cube of matter while the pro-material rifle places that cube as an item. They also have some other special properties. These weapons work with the gunslinger official homebrew class. See below:

Anti-Material Rifle

Ammunition
Range 120/360
Reload 1
Misfire 3
Two-Handed

2d8 piercing
1d8 necrotic

This weapon deals an additional 1d8 necrotic damage against constructs.

This weapon has 9 charges. Instead of firing this weapon at a creature, this weapon can expend charges to store one of the following materials at a time:

- 5 cubic feet of water (cost: 0 charges)
- 5 cubic feet of loose dirt (cost: 0 charges)
- 1 loose object able to fit within one's hand (cost: 0 charges)
- Up to 5 square feet of wood (cost: 3 charges)
- 1 loose object weighing no more than 30 pounds. (cost: 3 charges)
- 5 square feet of stone (cost: 6 charges)
- 1 loose object whose dimensions do not exceed 5 ft. in any dimension (cost: 6 charges)

1d6+3 charges are regained at dawn.

Pro-Material Rifle

Ammunition
Range 120/360
Reload 1
Misfire 3
Two-Handed

2d8 piercing
1d8 force

If the target of an attack with this weapon is a construct, it instead causes the target to regain 1d4+4 hit points.

Instead of firing this weapon at a creature, this weapon can be fired at an unoccupied space within range. The point must be touching the face of a solid object such as the ground or the side of a tree. When fired in this way, you may place the item stored as a charge from the Anti-Material Rifle at this point. This item is effected by gravity as normal.

You may also fire this weapon to create a 5 ft cube of crystal at a space within range. This point must also be touching the face of a solid object. The crystal will shatter if it takes any damage. If the Pro-Material Rifle is fired in this way again, the previous crystal loses its integrity and immediately shatters. If placed underneath a creature, the creature is raised 5 feet by the cube, unless it would crush the creature, in which case, the crystal shatters before any damage is dealt to the creature.
