Build Overview

This all round build is designed so you can use whatever weapon you want and deal great damage with it. The choice is yours when it comes to what you bring to the fight, this build will raise its power to the maximum! Whether mobbing or bossing you will be UNSTOPPABLE.

We use the Peacebreaker Cannons to support the carnage grabbing Instinto for the chance at crit and the ability to extend our actions skill uptime whenever we kill an enemy perfectly coupling with Juerga.

Extending action skill uptime is critical for this build as we'll be using the Dancer class mod which increases our overdrive bonuses (of which there are a lot) by 100% and getting one with a point in Soltado adds another 100% on top of that with Temerario the second most best skill for this build.

While Overdrive is active we get massive bonuses to all of these skills:

Barrage
Temerario
Las Jaras
The Thrill
El Soldado

We are at our strongest in this build 10 seconds into Overdrive where Temerario is all stacked up and we are at full health to get the bonus from El Valiente.

We gain ammo regen with Las Jaras perfect for sticky stacking and Metal Management gives us free ammo for 2 seconds whenever we activate or re-activate our Peacebreaker Cannons.

Instinto and Juerga are critical for extending Overdrive duration.

Soltado & Jaque increase the effectiveness of all our Overdrive bonuses.

We are better with splash damage weapons thanks to Barrage so look for those Torgue Licensed Accessories.

Al Centro is incredibly important in this build to offset the negative Gun Handling of Temerario which is more noticeable with 10/5. It takes a little bit to balance out but since it doesn't cap you're accuracy will be INSANE when Overdrive has lasted long enough.

Equipment

Weapons

Repkit & Ordnance

Utilities

This build doesn't paint you into a corner so the items here are pretty generalized so they will apply to all weapons.

Shield

Super Soldier provides a number of great bonuses which all guns benefit from (stickies the most)

Firewerks is another great shield, especially while mobbing

Watts 4 Dinner is also a great shield.

Ordnance

We use the Crit Knife found on purple (or higher rarity) Jakobs Grenade's. This increases our ctir chance offering more dps.

Repkit

Triple Bypass is ideal while mobbing to get our action skill back instantly thanks to Now With Caffeine.

War Paint is another good option to increase our DPS

Any Order Repkit with good rolls is great too

Enhancement

The ideal all round enhancement is a Torgue Enhancement with the Head Ringer perk and the following rolls:

Gun Damage
Gun Magazine Size
Splash Damage

You can get more damage from your enhancement by looking for weapon type rolls such as Shotgun Damage etc.

Gameplay

This build can play in a number of different ways, it's designed so you can do what you like and not worry about whether you are going to deal enough damage. In saying that, splash damage weapons will perform better than their non-splash counterparts.

General Play

You can use any weapon in this build, especially while mobbing. The key is to continue killing things so you can keep those Overdrive bonuses intact & if the boss arena has adds, kill one to proc Soltado.
