Pestilence is a cheat code while Golden bullet is active.

I am in no way a leet player, and this is by no means a "meta build" but I have found a fun build that makes Golden Bullet ridiculously fun for me. Running Gunner spec using the striker drone and the reviver hive. Using the Ninja bag to get the 3 piece striker ROF bonus (Knees+ holster) the 3 piece Petrov LMG dmg/handling/ammo cap (chest with unbreakable (for when i am dumb) and contractor's gloves,) and a sys corruption piece for armor on kill. Focus on gear is weapon dmg and crit chance. This + golden bullet procs turns the Pesti into a BRRRRT monster, and all those pesti procs kill targets in cover and cause more GB procs, it's just hilarious. Even better with this simultaneous XP event!
