Build Overview

This build for Rafa will take a previous build and make it a boss melting machine.

we will be putting points into melee and gun damaging but allowing them to be used into our grenade damage output to 1 shot everything.

its a simple build to follow and use.

Strengths And Weaknesses

boss melting
fun to use
unique playstyle

5/5

Peacebreaker Cannons in most cases is the way to go when using Rafa. high damage output with the critial hits which makes this build amazing. putting points into Sitiar and other gun damage / melee damage skills which increases gun damage will also increase our grenade damage by using Bear Arms in specializations. The skills we picked here are not 100% perfected but in the gameplay shown in the attached video i have made, we are able to kill any boss within seconds and run any mobbing situation easily. By using Insta-Fort Battle System when pressing the skill button you will throw a turret that will also throw grenades dealing high damage.

Equipment

Weapons

Repkit & Ordnance

Utilities

For weapons, it wont matter much due to them not being used but 1 Kinetic weapon like the Hot Slugger will be great due to its 90% increase in damage after 3 kills. we want 3 weapons with 3 different elements because our Slippy will also deal the damage of the element in our equipped weapon. our AF1000 repit with either Hard Hitter or Go Go Gadget will give us increased melee damage (into our grenade damage) or decrease our grenade cooldown for more uses.

Slippy is the grenade of choice due to high damage output. The swordfish perk will cause the grenade to deal melee damage.

Grenazerker class mod with atleast 5 points into Confeti will give us a major bump in damage.

Gameplay

start the fight by using Peacebreaker Cannons and then using your repkit to increase damage. pressing your skill again and using Insta-Fort Battle System will throw a turret to also use grenades. start spamming your grenades and watch everything die.
