From : quest called "imprecations" after reaching RANK 5 on Gunsmith / Banshee.
- You can get a one time +500 rep to Gunsmith by finishing Shaxx's crucible quest.
- You DO NOT get rep from the weapon/extra bounties they crucible offers AFTER completing said quest.
The Basics: DestinyDB Quest info
Step 1: Get Hand Cannon kills with a Primary or Hand Cannon Telemetry active. After, speak to Banshee at the tower.
TIP: Do this at seige of the warmind, or patrol, etc. Pretty quick.
Step 2: Wait for Tex Mechanica's next Armsday delivery. Armsday occurs every Wednesday. After, speak to Banshee at the tower.
Step 3: Infuse the weapon, get kill sprees, and go on a precision kill spree in the Crucible.
Infuse the Weapon
Seven Kill Sprees (7x "3 kill sprees") of any type
>> This is defined as 3 kills of X type within a life**. Example: 3 headshot spree within a life, machine gun spree, shotgun spree, etc.
Seven "Precision" Kill Sprees (7x "3 headshot kill" sprees).
>> The is defined as 3 kills with precision damage as the fatal shot within a life. I don't believe they have to be sequential.
Tips: Similar to doing the Chaperone quest, play smart. Don't rush. Ranged weapons are probably better. Try a sniper! :) Control is a better game type to play. When complete, go speak to Banshee.
Step 4: Wait for Tex Mechanica's next Armsday delivery. Armsday occurs every Wednesday. Talk about time gates?
Step 5: Go talk to Banshee, money! Gun should drop here. :)
