Build Overview

HAHA YOU THOUGHT IT WAS A FORGEDRONE BUILD BUT THEY SUCK BUTT

This is a build focused around the Kill Drone alt fire that acts like a companion which deals an INSANE amount of damage. You can find this from Order AR underbarrels. This is basically just min maxed version of the "Deputy Style" of my Aim On Amon Gun Build

This was inspired by Ratore's Dronemancer Vex Build

IMPORTANT INFO:

Credit for testing the Kill Drone goes to Ratore, Iserrot, Katchenz and Nepta

Kill Drone gets On Shot Bonuses on spawn and keeps it and then On Hit Bonuses when the drone shoots which only applies when it's active

The damage formula is Card Damage x On Shot Bonuses (including Amp) x On Hit Bonuses

To learn more about the damage formula then check out the General Damage Formula Guide

Action Skill:

Calamity - used for the easy bonus element. The movement speed and shield recharge helps with survivability

Force of Nature - insane for single target. Go to bossing damage dealer. Detonation is a double dip based on the strongest 10 shots that applied Primed. The detonations can also help with bossing.

Stormcutter - proc detonations, extend AS duration, and give AS and Ordnance Cooldown. A lot easier to apply Forge skill damage for detonations compared to base Molten Slam.

Red Tree:

Impetus - increased movement speed for Bullet Train & recharge rate for survivability

What Burns Within - increases Onslaughter bonus element

Gut Punch - Damage boost that double dips in Force of Nature detonation. Also only 1/3 because the damage isn't that needed unless you are bossing and Slippy keeps it up easily

Tritanium Knuckles - Skill damage boosts Berserk bonus element, Dragon's Breath, and Force of Nature

Bullet Storm - increased gun damage

Forged In Steel - Immunity to damage which helps survivability. Not a focus for survivability just kind of nice. And we spam our Forgeskill pretty often.

Bloodlust - gain some lifesteal which is nice but really to get down the tree for capstone

Berserk - Cryo bonus element for your guns and melee. Mainly here for the guns. Does not apply to Force of Nature nor DoTs.

There Is Only Red - Boosts your Berserk bonus element by up to 210% at 5/5

Rimebreak - Used for the freeze to help aggro relief. So only need 1 point as it's not for damage.

My Touch Is Death - activates your kill skills. Procced by Slippy. Mainly helps with There Is Only Red.

Catastrophe - increased crit chance and crit damage for your drpme and whatever else crits from crit chance. Easy to keep up with Onslaughter bonus element and Electrical Fire

Dragon's Breath - applies to the Kill Drone but does not make the drone shots fire

Fists of Stone - Using Slippy you can easily keep up your Forgeskill

Electrical Fire - Mainly for helping keep up Catastrophe

Blue Tree:

Battleborn - increased gun damage

Utilities

Gun:

Tediore AR - Kill Drone Underbarrel. Highest damage I've seen is about 4,000 base damage. Get it with a Torgue Part for Head Ringer Enhancement which is basically free damage. That is the only part that matters. Manufacturers parts aren't procced by Kill Drone bullets. Ideally you want 4 copies for each slot

Goalkeeper - can roll Kill Drone as well but from what I have seen has lower base damage and cannot roll Torgue part. But is at least a start to the build. If anything you may just need better gear.

Ordnance:

Slippy - Main Grenade. Used to proc My Touch Is Death and Fists of Stone. Get + 1 charge part.

Shield:

Firewerks - Used for mobbing.

Watts 4 Dinner - Get as many amp parts as possible. Can get up to 150% Amp. Also good for the shock bonus element and overshield for survivability

Class Mod:

Passives to look out for: Damage Dealt, Kinetic Damage, Gun Damage, Skill Damage, and anything else that benefits

Furnace for points in Dragon's Breath

Repkit:

Triple Bypass - Needs Amp Part. Kill Drone will benefit from this. Then also good for Now With Caffeine to cycle Onslaughter

Enhancement:

Passives to look out for: Gun Damage and Assault Rifle Damage (On Shot Damage)

Torgue Enhancement Head Ringer - The gun damage is On Shot so it is VERY strong here.

2/3 High Caliber - The Gun Damage is On Shot so very good here

High Caliber is the only MUST HAVE firmware. Everything else is situational. Can just mess around with utlity stuff. The only time you may have to squeeze damage is for big boss melts.

3/3 Deadeye - Lots of crit damage. Only boosts weakspot hits and not crit chance hits. Crit chance hits does stack the effect. Drones can sometimes naturally crit.
