I had an idea for this a few years ago: 1. Earning a weapon unlocks its “Blueprint” in collections. Clicking on a weapon brings up a traces blueprint of the weapon with a side panel of all possible perks and barrels, all greyed out. 2. Deleting a weapon unlocks nodes in the Blueprint based on what it had (deleting a Bygones would unlock Corkscrew Rifling, Fluted Barrel, Armor-piercing sounds, Ricochet Rounds, High Impact Reserves, and Kill Clip) 3. Once you have deleted enough weapons to have all perks you want unlocked, you can select a button on the Blueprint for the weapon labeled “Craft”. Alternatively, the Craft option could be greyed out until every possible perk is unlocked to increase grind. 4. This brings up the chart of all perks/barrels/ammo traits. Pick from what you’ve unlocked, filling out a traditional set of perks, and click “Begin Crafting”. Price is 10,000 glimmer. 5. This generates a legendary quest titled “Weapon Smith: [i]Weapon Name[/i]. Go visit Banshee-44 to begin. 6. Banshee will begin working on the frame, but will need special telemetries in order to code the right perks into the weapon. He will ask you to complete a significant number of objectives with a gun frame (I.e. gun with no perks). Hypothetically, Bygones would want: 150 headshots: Barrel telemetry 150 body shot kills: Barrel telemetry 300 3-burst hits: Bullet telemetry 500 kills: Bullet telemetry 200 double kills: Perk telemetry 25 Major or higher kills: Perk telemetry 7. Bring collected telemetries to Banshee. He will offer you a quest step to choose your Masterwork, and you will need to again go create a telemetry. The path for this can be a mission, kills in a certain way based on the Masterwork, etc... 8. Once Banshee has all telemetries, he will inform you that your weapon is nearly finished, but it will need a power cell to attach and activate all of the perk telemetries. This can be found either by completing a 100k Nightfall, winning 3 Crucible matches, or winning 2 Gambit matches. 9. Banshee uses the power core to fuse the perks into the frame, crafting your perfect weapon. However, he will need your help in replenishing his supplies, so his fee will be the following: 35 enhancement cores 100 legendary shards 250 weapon parts 25 of each planetary resources 5,000 glimmer 10. After paying for his services, you will be rewarded with a legendary gun, Masterwork set at 5/10, with your full set of choice perks. Hopefully this makes the process of crafting a god roll long, but not unfair, and the costs are high enough to justify a custom roll
