The Visionary Gunsmith
A Visionary Gunsmith uses their creative mind to design their own shooters. To them, combat is a testing ground and an opportunity to show off their deadly toys. When they are not in battle, they can often be found tinkering at a workbench or polishing their crossbow. They can be ready for anything, given they have a little inspiration and a loaded gun.
Personalized Prototype
When you choose this Fighter archetype at 3rd level, you learn to create your very own prototype with enhancements and upgrades.
Prototype: You can customize any ranged weapon that doesn't have the Thrown property with enhancements and upgrades. You can only have one prototype at a time until 18th level, when you can have an unlimited amount. If customize another weapon, your last prototype breaks. You must spend 10 minutes performing maintenance on a prototype once every 24 hours for it to remain functional.
Enhancements: You can attach a maximum of two enhancements of your choice to your prototype, given you have the prerequisite materials, which attach to your prototype. These materials are reusable unless expended or destroyed. You can add one more enhancement at 7th, 10th, and 15th level. You can add, remove, and swap enhancements at the end of a long rest.
Upgrades: You can upgrade a maximum of one enhancement of your choice on your prototype. You can upgrade one more at 10th and 15th level. You can add, remove, and swap upgrades at the end of a long rest.
Ranged Artisan
At 3rd level, you gain proficiency in your choice of Smith's tools or Tinker's tools.
Advanced Research
At 7th level, you have done research to adopt more peculiar ideas for your prototype designs and combat style. You gain proficiency in two skills of your choice from Arcana, History, Nature, and Religion, and you also learn the Mending cantrip.
Curving Shot
At 7th level, you learn how to modify your errant projectiles to direct toward a new target. When you make an attack roll with a round of ammunition from your prototype and miss, you can use a bonus action to reroll the attack roll against a different target within 60 feet of the original target.
Gunsmith's Hands
Starting at 15th level, you can add, remove, and swap out enhancements and upgrades at the end of a short rest.

Gunslinger's Arsenal (optional)
At 3rd level, instead of using the rules for crafting found in Xanathar's Guide to Everything, you can spend 48 hours over a period of 6 days or fewer crafting your own gun from the Gunslinger's Arsenal. Doing so requires materials worth the cost listed on the Gunslinger's Arsenal table.
Gunslinger's Arsenal Properties
These firearms are volatile, and as such bring their own unique set of weapon properties. Some properties are followed by a number, and this number signifies an element of that property (outlined below). These properties replace the optional ones presented in the Dungeon Master’s Guide.
Reload. The weapon can be fired a number of times equal to its Reload score before you must forgo an attack or spend an action to reload. You must have one free hand to reload a firearm.
Misfire. When you make an attack roll with a gun from the arsenal and the d20 roll is equal to or lower than the weapon’s Misfire score, the weapon misfires. The attack misses, and the weapon cannot be used again until you spend an action to try and repair it. To repair your firearm, you must make a successful Smith's Tools or Tinker’s Tools check (DC equal to 8 + misfire score). If the check fails, the weapon is broken and must be mended out of combat, which requires
a quarter of its cost in materials. Creatures that use a firearm without proficiency increase the weapon’s misfire score by 1.
Explosive. Upon a hit, everything within 5 ft of the target must make a Dexterity saving throw (DC equal to 8 + your proficiency bonus + your Dexterity modifier) or suffer 1d8 fire damage. If the weapon misses, the ammunition fails to detonate, or bounces away harmlessly before doing so.
Ammunition
Ammunition for guns from the arsenal may be near impossible to find or purchase. However, if materials are gathered, you can craft ammunition yourself using your Smith's Tools or Tinker’s Tools at half the cost. Each gun uses its own unique ammunition and can be crafted in batches listed next to the cost on the Gunslinger's Arsenal table.

Quick Customization
There are more than 11.5 million possible prototypes you can build, but you can customize one quickly by following these suggestions. First, choose a weapon based on your campaign setting. Ask your DM about what is and isn't allowed. Second, roll on the Prototype Enhancements table a number of times equal to your maximum number of enhancements to determine which ones you add. Reroll if there is a repeat or if you don't have the prerequisite materials. Third, to determine which enhancement(s) you upgrade, refer to the ones you've added and roll based on your level:
Levels 3-6: Roll a d4, assigning each enhancement to a pair of numbers.
Levels 7-9: Roll a d6, assigning each enhancement to a pair numbers.
Levels 10-14: Roll a d8, and then a d6, assigning each enhancement to a pair of numbers for each roll.
Levels 15-20: Roll a d10, a d8, and then a d6, assigning each enhancement to a pair of numbers for each roll.
