My take on the standard
Nuclear Winter
Group Study Green Tree Harlowe gun build.
Infinite Crits, Infinite Ammo, Infinite Amp, Infinite Action Skill, Infinite Damage


















Flux Generator - used for the augments and capstone
Nuclear Winter - used for keeping up
Excited State and
Distribution Function to then go with other skills
Group Study - gun damage is on shot (mult with normal gun damage) and the other stats are amazing for DPS
Momentum - easy to keep up
Mass Function - reload speed helps for certain guns. Personal choice. Can mix points around with
Neutron Decay
Neutron Decay - gun damage is easy to keep up
Confirmative Reality - super easy to get back
Flux Generator with this. This is a key skill
Decoherence - great consistent inheriting bonus element
Feedback Loop - helps keep up and cycle Action Skill
Latent Charge - solid bonus element that's easy to keep up. Does not benefit from gun damage but DOES benefit from skill damage. Becomes an inheriting bonus element when applied to
Decoherence
Runaway Reaction - helpful to entangle enemies when
Flux Generator is on cooldown to then get
Confirmative Reality procs going
Harlowe's Certainty Principle - better QoL and more projectile speed
Critical Funding - grants free ammo. it is not taking from reserves. This is a key skill
Meltdown - inheriting gun bonus element
Excited State - allows for infinite crits as every gun shot activates this via
Nuclear Winter. Great w/ Jakobs Ricochet part. This is a key skill
Refraction - allows for easy ricochets for better mobbing. This used to be broken but works now
Distribution Function - allows for easy upkeep of Amp shields and overshield. This is a key skill
Accretion - nice extra survivability
Make Extraordinary - while our gun shots get auto crits our bonus elements do not. Since most of our bonus elements are skill this helps a lot there.








I like to focus on stickies and ricochets with the use of infinite ammo and crits to make it feel different than other gun builds but you can use literally any gun. Experiment as much as you want.
Stray - mobbing GOD. must have item. Get w/ either jakobs and/or daedalus shotgun
Convergence - great for mobbing and bossing. Get w/ jakobs ricochet
Darkbeast - amazing for mobbing and awesome for bossing. Get w/ Jakobs ricochet and Daedalus Shotgun. Can replace Daedalus w/ Maliwan element switch for mobbing.
Crow-Sourced - go to for bossing. Pair with
Active Fire
Jakobs Shotgun Spread Launcher - go to for bossing. Pair with
High Caliber for double hit.
Shalashaska - w/ Torgue Impact and Shotgun Mode for amazing mobbing.
Stop Gap - Amazing for bossing. Get w/ Jakobs ricochet
Complex Root - bossing GOD. Get w/ Atlas darts and Jakobs ricochet
Rowan's Charge - great for mobbing
Lucian's Flank - great for mobbing
Wombo Combo - w/ Ripper
Goalkeeper - w/ Jakobs Ricochet
G.M.R. - w/ Jakobs ricochet
Fisheye - w/ Jakobs ricochet
Jakobs Shotgun Balor - w/ Torgue impact for mobbing
Vladof SMG Boory - w/ Torgue impact and Jakobs Ricochet for mobbing. Use extra barrel alt fire
Firepot - counts as a gun so it spreads
Nuclear Winter for a better ranged option to apply Entangle
Jakobs Grenade Crit Knife - helps with our bonus elements critting
Slippy - can be used w/
CQC as well as breaking Vile Crystals
Triple Bypass - used for multiple charges to heal since there isn't much survivability otherwise. Any good part can be used as w/ low cooldown + low healing or long cooldown + high healing
Kill Spring - used in mobbing for amazing healing as long as you are getting kills
War Paint - more fire rate is better DPS
Passives to look out for: gun, gun type, elemental, element type, crit
Phlebotomist - w/ points into
Sustained Reaction. Go to for mobbing and bossing as it is a double dip based on status effect.
Bio-Robot - Used for the skill points in
Confirmative Reality and
Sustained Reaction to improve mobbing a lot. Get tons of
Group Study stacks w/o worrying about the AS Duration Drain
Reactor - for the points into
Decoherence for bossing
Watts 4 Dinner - w/ Amp and/or Siphon. Great for both mobbing and bossing
Guardian Angel - w/ Amp. Great for both mobbing and bossing. Preferred over Watts when using Torgue Stickies because of better recharge rate since there won't be good uptime on
Distribution Function for keeping up amp.
Protean Cell - good for bossing. Can also be another good choice for stickies.
Firewerks - amazing choice for mobbing. Benefits from
Nuclear Winter and
Latent Charge
Passives to look for: gun damage, gun type damage, fire rate
You are basically using any good enhancement that synergizes w/ your guns. I will list a couple I know work great
Jakobs Enhancement - Bounce Pass (extra ricochet) and Sequencer (increased damage after critting)
Torgue Enhancement - Head Ringer (increase damage and splash radius)
Ripper Enhancement - High Roller (increased damage on consecutive hits) and Short Circuit (chance to increase fire rate after reload)
Vladof Enhancement - Bullet Hose (chance for extra projectile) and Box Magazine (increased fire rate and mag size)
Order Enhancement - Power Shot (increased damage on full charge)
Atlas Enhancement - Trauma Bond (increased damage w/ Target Lock) and Protractor (chance to not consume ammo)





3/3
Deadeye - super easy to keep up because of
Excited State
2/3
High Caliber - consistent gun damage but additive w/
Group Study and enhancement gun damage. Can go 3/3 for the pierce if certain weapons like it.
Other options depending on guns:
Atlas EX - for on shot gun damage
Atlas Infinum - for on shot gun damage
Heating Up - for reload speed w/ guns that have you end up reloading
Airstrike - splash radius
Get Throwin - more splash radius
Bullets to Spare - more fire rate
Daed-dy O - on shot damage and fire rate
Oscar Mike - bit of QoL gun stuff
Trickshot - extra ammo return can be nice w/ guns that don't easily benefit from
Critical Funding
Riddle You This - easy to keep up with most guns used
Bullet Train - solid gun damage
I Am A Gun - actually skill damage which will benefit all our shots because of
Nuclear Winter
Groundbreaker - built up from gun, inheriting bonus elements, and
Nuclear Winter while groundbreaker also gets inheriting bonus elements.
Flexible 4th options:
A Honed Mind - because of
Nuclear Winter and
Excited State the crit damage is always active
CQC - fire rate easily procced by
Slippy
In The Zone - easy damage boost
The Best Defense - solid damage boost
Activate
Flux Generator
Retrigger from time to time for
Group Study
Shoot gun and win
Throw grenades when needed.
