Build Overview

The goal of this build is to keep your Peacebreaker Cannons up permanently to grant Overdrive bonuses. In doing so, you will also do a ton of damage with your Hot Slugger and that damage can chain into other enemies.

To keep your Peacebreaker Cannons up, you will want to run the Instinto augment and Juerga skill. This will allow kills and critical hits to extend their duration. While they are active, you will be granted Overdrive and this can be buffed with our class mod the Dancer.

Overdrive on its own will already grant damage and movement speed, but we can buff that even further. With skills like Resiliencia, Barrage, Temerario, Soltado, and Jaque you will get even more damage, splash damage, damage reduction, and the ability to buff all those bonuses up even further.

If you ever run out of Peacebreaker Cannons, skills like Preparado is great since you will be reloading a lot. You can also take advantage of your repkit with acceleration and your specialization Now With Caffeine to get it back very quickly.

The final skills are Vitriol and First Impression to get bonus damage with the first shot in the magazine. Since the Hot Slugger has one shot, you will always be granted the bonuses.

The main weapon you want to run with this is the Hot Slugger. As mentioned above, you can take advantage of Vitriol and First Impression all the time. On top of that, it also does splash damage so it will get buffs from Barrage alongside all the other Overdrive skills.

To buff those Overdrive skills, we can take the Dancer class mod, which will grant an additional 100% bonus. This will also make it so when your Peacebreaker Cannons end, you will lose all Overdrive bonuses, but that's no big deal because this rarely happens, and if it does, you have your repkit.

Any repkit with the acceleration perk will work, but if you can get an Order Repkit it can have two charges. Acceleration will grant 100% action skill cooldown rate, and while this can only proc once, if you have the specialization Now With Caffeine it will stack and almost instantly refill your Peacebreaker Cannons. It is worth noting a two-charge Order Repkit is good because it can proc Now With Caffeine twice. So essentially, if your Peacebreaker Cannons run out, hit your repkit twice and instantly get it back.

The final thing that isn't needed, but works with the build, is theFirewerks shield. This will make getting a kill spawn fireworks that do a ton of damage to enemies. Pairing this with the ricochet from Hot Slugger it will make it so that getting one kill will get multiple kills.

For your firmware, you want three Deadeye, as this is going to be your go-to. This will grant crazy critical hit damage bonuses. You can then pair that with two Trickshot for some extra reload speed and even more critical hit damage.

The goal with this firmware is to buff your critical hit damage up a ton. This is really easy to do with the three-piece stacking of Deadeye, and you also get a little bonus from the two-piece of Trickshot.

Specializations

Specialization 2I Am A Gun

Specialization 3A Honed Mind

Specialization 4One Shot, One Kill

Now With Caffeine is the most important with this build. Pairing this with your gear will allow you to get instant action skills off cooldown.

I Am A Gun is also nice since you will be granted a lot of weapon damage bonuses. This, in return, means more action skill damage.

A Honed Mind works perfectly because you want to get crits, and your augment is already granting extra critical chance.

One Shot, One Kill honestly isn't crazy with this right now because any damage procs it. So if you get a crazy excess damage shot, your action skill just proc it. While it's still more damage, it would be better if it only worked on gun damage, so you could chain it with your weapon.
