Build Overview

This build is designed to give Rafa a bossing option outside of underbarrels & COV rolls, by opening the door to Ordnance. The Loiter Sploiter is key to this a Torgue Heavy Weapon that deals incredible damage in this build.

This build can also play as a traditional gun build for mobbing with great grenade support through the Waterfall or Jelly.

As with most Rafa builds we do use the Dancer with Peacebreaker Cannons serving as our action skill & Insta-Fort Battle System accompanying us as our augment, providing extra Ordnance damage.

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

Barrage
Temerario
Collaborate Ignition

Collaborate Ignition is the key one for Ordnance Damage & Soltado on our class mod makes it even better.

Strengths And Weaknesses

Rafa can kill bosses quickly

Mobbing can be cumbersome
Central bossing weapon is paid DLC

The key skills that make this ordnance focused are Confeti & Collaborate Ignition which leaves the option open to run this as a traditional Splash Damage gun build while mobbing & leave the Loiter Sploiter to handle the tough stuff.

Equipment

Weapons

Repkit & Ordnance

Utilities

Key items are AMP items. We want an amp shield & amp repkit to maximise our one shot potential for the Loiter Sploiter.

Look for a repkit with Amp (Amplified) & a shield with AMP Synergized.

Best amp repkits

Getting a repkit with Overshield (Synergizing) guarantees we proc the Watts 4 Dinner's unique effect.

Weapons are open here, key thing is Splash Damage & that you have enough elemental variation between them to cover all health bars to get the maximum benefits of Collaborate Ignition.

Dancer is hard to look past, boosting our Overdrive skills & making us stronger across the board.
