Moze (Gunner) Boss Killer Build Guide

Last updated on Nov 13, 2019 at 16:00 by Motoko 3 comments

Welcome to our Boss Killer guide for Moze the Gunner in Borderlands 3. Featuring several damage multipliers and the ability to extend the firepower of already powerful guns like Lyuda and Cutsman, this build sports the fastest boss kill times. Here, you will learn everything you need to know to gear yourself up and play this build at the highest level.


Boss Killer Moze

By heavily investing in the Bottomless Mags tree, this build coupled with specific Vladof and Maliwan weapons provide the fastest boss killing potential since Porcelain Pipe Bomb nerf. Embracing the adage "the best defense is a good offense" the following build offers little in terms of survivability, in exchange for the ability to melt bosses in a handful of seconds, at worst.


Skill Tree



  • Extremely fast at killing bosses.
  • Good enough survivability.
  • Requires only a primary weapon and a secondary of your choice.


  • Iron Bear used only to enable some Anointed Traits (if you have any)
  • Weapon dependent.


Boss Killer Moze playstyle is extremely simple and it is meant to be as quick and effective as possible. Start the boss encounter in Iron Bear, pop out to proc any anointment effects you may have and to enable Some for the Road Some for the Road. Delete Boss with the appropriate elemental weapon; rinse and repeat.


Boss Killer Moze Skills


Skills Breakdown

  • Cloud of Lead Cloud of Lead improves our ammo efficiency while Redistribution Redistribution and Forge Forge provide continuous ammo regeneration for the active weapon.
  • Scorching RPM's Scorching RPM's together with “Click, Click...” “Click, Click...” provide increase gun damage.
  • Matched Set Matched Set and The Iron Bank The Iron Bank combined almost double the baseline magazine size of any weapon, which in turn also double the ammo regen from Forge Forge and Redistribution Redistribution.
  • Some for the Road Some for the Road allows us to burst down targets and bosses in 1 Cutsman or Lyuda clip.
  • Rushin’ Offensive Rushin’ Offensive is a quality of life change, mostly to speed up even further our farming. Gotta go fast!
  • Thin Red Line Thin Red Line and Vladof Ingenuity Vladof Ingenuity are used to increase the shield pool and increase our survivability.
  • Experimental Munitions Experimental Munitions adds some extra Incendiary damage everytime we score a Critical hit.
  • Desperate Measures Desperate Measures increase weapon damage by a noticeable amount.

Action Skill, Augments, and Elements

Iron Bear is mostly used to proc Some for the Road Some for the Road and anointed effects, thus its loadout is more of a personal choice. I like to run with double Salamander Salamander, augmented with both Fuel Economy Fuel Economy and Molten Roar Molten Roar for the extra mobility.


Alternative Skill choices

The 1 point in Rushin’ Offensive Rushin’ Offensive can be reallocated into Scrappy Scrappy for faster weapon swap.


Boss Killer Moze Gearing


Best in Slot

While maximizing Matched Set Matched Set is not as important as in Maliwan Moze, it is advisable to get at least 2 matching weapons and a grenade mod of the same manufacturer to be able to dispatch a boss within the 5 seconds of Some for the Road Some for the Road and the remaining clip under negative mayhem 3 affixes.

For the primary weapon, there are 2 main boss killers:

  • Lyuda is the first choice. A Sniper Rifle with the rate of fire of an Assault Rifle, the gun is only limited by its magazine size and reload time. Fortunately with this particular setup we can double the starting capacity which coupled with Some for the Road Some for the Road and any eventual anointment effect allows us to fire continuously till the boss is dead (provided it doesnt have immunity phases). Ideally found with the Annexed affix, it is recommended to have an Incendiary version, and a shock one as backup for high Shield bosses.
  • Cutsman is the other obvious option. Try again to have multiple guns with Incendiary/Corrosive/Shock damage to deal with the corresponding health bar.

Last weapon slot is for the Sellout in case we want to hunt red health bosses, and it is best paired with an Elemental Projector artifact.

Regarding Class mods, Bloodletter synergizes with the build, but it is not mandatory. There are simply no other options that stand out for the time being.

When choosing the Artifact, Deathless offers the highest damage increase unless you have a class mod that gives you at least 2 extra points in Thin Red Line Thin Red Line; if that is the case, then using a Grave offers even more damage at the expense of further lowering our shields.

The Re-Router Shield is the offensive choice, providing even more damage on our first shot. Ward can be a good alternative, although somewhat risky. If you prefer instead a safer approach, your best options are The Transformer, Re-Charger, and Stop-Gap.

Grenades mods are mostly used to extend primary weapon magazine size through Matched Set Matched Set; pick any Vladof mod if you run with Lyuda, or a Tran-fusion for added sustain if you run with Cutsman since there are no Maliwan Grenade mods yet.


Anointed Rolls

Anointed rolls are special additional effects that can appear on weapons and shields at higher levels. The special effects relate to the use of action skills and provide powerful temporary buffs.

Boss Killer Moze build greatly benefits from Action Skill End rolls such as:

  • 'On Action Skill End, the next 2 magazines will have 50% additional bonus Element Damage' works extremely well as we basically never reload, making that an almost always active bonus on a given weapon.
  • 'After exiting Iron Bear, the next 2 magazines will have 40% bonus Incendiary damage', is numerically a worse roll than the generic one, but it always comes with Incendiary Damage as the upside.
  • 'After exiting Iron Bear, gain 75% increased shields and health for 25 seconds.' offers the best defensive capabilities, and can be used to complement an extremely glass-cannon loadout.

Alternative Gear from Missions

The build relies on a tight combination of specific legendary items, thus there is no viable alternatives from missions.
