5/5

Beyond cursed Green Tree I know. That's why Doomsday 'Approaches'. Levels caps will be monumental.

Reverburnations is a Double dip, and is skill damage, allowing it to proc it's own Bloodletter, for a Triple Dip.

Kill skill route for large amounts of Gun damage, which gets pulled from over and over thanks to Specialisations. And Grave Sights, one of the largest stat boosting skills in the game, gets dipped into multiple times through Reverburnations and Bloodletter.

Equipment

Weapons

Repkit & Ordnance

Utilities

GUN

Mantra of course!

Get a healthy selection of element spread. Ripper Parts for Bossing, and Jakobs Parts for Mobbing.

A high enough fire rate on a Ripper mag can reduce the charge time to near zero.

Jakobs Shotgun This is a Spread Launcher. It is for Vile Enemies. Also Boss one shots.

Class Mod

It's Teen Witch. Infinite AMP uptime.

A good FIREDANCER purple with up to 5 points into Reverburnations can be a good substitute, esp vs flesh targets.

Passives to look out for: Skill Crit Chance. All Damage. Gun Damage. Gun / Melee Crit Chance.

REPKITS

Accelerator is the important part here. Attach it to any Repkit you'd like.

War Paint offers Movement Speed and Fire Rate.

Order Repkit with AMP to improve Spread Launcher Damage. Makes it good for boss 1 shot kills.

SHIELD

AMP, up to 150%

Watts 4 Dinner Can roll AMP. Gives a 25% bonus element that can proc it's own Mortal Terror. It can also proc (and steal) it's own Bleeds, so watch out for that if you're trying to get a big Spread Launcher Bleed.

Ordnance

Jakobs Grenade with Penetrator Augment for crit chance. Reverburnations needs to crit, but cannot crit on a headshot. So 30% per throw is pretty mandatory.
