Build Overview

Rafa's Peacebreaker Cannons are incredibly powerful for leveling right off the bat, offering extremely high damage output especially with the capstone Beam Team turning them into literal lasers. They scale off of any gun damage increases, so not only are you buffing your own gun damage, you're also increasing the damage of your turrets. They can have almost 100% uptime by taking advantage of Juerga early on, and later Inspirado ensures they are up whenever you need them. This means you don't need to put many points into cooldown rate, and you can instead put your points into powerful damage increases, namely Temerario and Soltado are ridiculously good. Rafa's trees offer a ton of strong nodes, so whether you're looking for movement speed, damage, or survivability, you pretty much can't go wrong. From a first glance, this seems to be the best leveling build as it's incredibly straight forward and very strong from all sides.

Endgame Build:

Strengths And Weaknesses V1

Chill to play
Cannons have literal aimbot
High damage

Beam Team might feel weak against certain enemy types, or may fall off in the late game when enemies get elemental resistance. At which point you'll want to swap to the ricochet endgame build

Build Variants

Once you're in UVHM and around level ~40 I recommend transitioning into a Ricochet focused build linked here

Skill Point Order

Feel free to swap SOME damage points for either survivability or more movement speed, the last 9ish points are interchangeable. Specifically The Thrill or Expedite. If you're struggling by taking a lot of damage at any point consider using Resiliencia. If you want MORE movement speed at the cost of damage, put some points into Devil-May-Care

5 Sitiar
Instinto
5 Juerga
5 Deft Hands
5 Vitriol; this is mainly just to get to the Beam Team capstone feel free to put something else for a few points in the mean time such as Midnight Oil or Maestro and then respec to this once you have enough points to reach the capstone, which would be at level 25
4 Pain Reaction ; same caveat as the above node
1 Concentrated Build Up
Beam Team
3 Inspirado
3 Everdrive (this and the following node are only to get to Temerario, feel free to put 5 points into something else such as Midnight Oil or Maestro again and respec once you have enough to get Temerario which would be at level 34, I'd probably wait until 37 to perform the respec though)
2 Barrage
5 Temerario
1 Soltado
1 Resiliencia
Blue:
5 The Thrill (pick Midnight Oil if using a shotgun with 1 bullet)
Green:
4 Expedite

Penetrator Augment which comes on Throwing Knives is EXTREMELY powerful on bosses or any tanky enemies.

Guns: Pretty much anything will work well with this, Jakobs shotguns with 1 bullet in the mag synergize very well with Vitriol

Be on the lookout for the Spread Launcher, Beam Tosser, Shrapnel Cannon, Knife Launcher, Taser, or Shotgun underbarrel attachments and try them out, they are overtuned. These have internal cooldowns, you can bypass the cooldown by swapping to a different gun with the same attachment.

Repkits: 200% Amp, Lifesteal, & Movement Speed are likely the best options for smooth leveling.

Class Mod: Anything that gives raw damage is good. Inspirado would be good early on to keep up your Peacebreaker Cannons. Look for action skill duration that'll help out a ton.
