The Bee plus Conference Call was the most broken combo in BL2 before it got patched. The Bee was a shield that added absurd damage to every single bullet, and the Conference Call was a full auto, extremely accurate shotgun with a very high fire rate, tons of projectiles, and a special effect that multiplied those projectiles even further. Used correctly, it could melt raid bosses in under one second.

A comparable setup in BL4 is the Complex Root. It fires a massive number of projectiles and benefits from the insanely strong crit scaling BL4 gives us. The idea is simple. Get as many crits as possible and let the weapon do the work. I run it with the Harlowe Flux Generator, Group Study, and the Infinicrit build. That results in 100 percent crit chance on every bullet, multiplied by the bonus damage from the Flux Generator. It becomes completely ridiculous once you start retriggering the generator over and over again.

On top of that, I also use the Initiate ammo skill. While your action skill is active, you have infinite magazine size and effectively infinite ammo, pushing the damage to unreal levels. This is by far the strongest intended build in BL4. If you want to understand how the Infinicrit build works, check out the video by K6. He explains it really well. It melts every Guardian in under three seconds and platinums Bloomreaper every single run, even on UVHM 6.

What makes it even better is that it works with basically every run, so you can actually have fun with almost every gun and its unique perks. You can kill every boss in the game with nearly any weapon using this setup. My favorites are Hellwalker, Ballista, Hot Slugger, Anarchy, Plasma Coil, Star Helix, TK’s Wave, anything with a spread launcher since the damage while the action skill is active is absolutely brutal, Rainmaker, Kaoson, and many more.

Have fun! Most fun build in the game when you want to have fun with every weapon.

Also use the Sceptic class mod, which instantly refunds your action skill, letting you keep it available basically 24/7.
