Build Overview

Mantrarmy

These are gun-focused Mantra builds, where the melee and gun aspects are used as a source of skill triggers (Prismatic Weaponry, Reverburnations, Bloodletter), stacking up the damage formula to the brim.

  • All builds presented here come from theorycrafting between Ratore, LazyData and Iserrot.
  • The builds are fully capable in both Scaled and True UVH6.
    • Keep in mind that in True Mode, one inevitably benefits a lot from having better-rolled gear.

Rainbow LDKSMB

aka Ratore + LazyData's all-in-one Rainbow Kill Skill Mantra Build

This variant focuses on taking the damage per mag to its limits, featuring extreme peaks of damage due to the Mortal Terror triggers allowing maximum performance even during bossing encounters. It's an excellent setup, especially for tackling high end bossing content and even True Mode, while also being very straightforward.

1/5 Haruspex is there in case you want to throw handheld nukes through Haruspex + Groundbreaker.

  • Action Skill: Dead Ringer
    • Coven + Grim Reaper
    • Incarnate + Witchy Trigger Finger is available for niche applications.

Punch To Go!

I just really wanted an excuse to use Shot To Go!

This variant focuses on bypassing reloads, relying on the synergies between Prismatic Weaponry, Shot To Go! and the attunement system. Fun and involved, but not everyone will prefer it since it requires getting into Tier 5 of bottom left blue tree, also known as the 'did they even test or play any of this' part of Vex's kit.

Between the builds, it has the least total power, but the usage of Shot To Go! results in a unique gameplay loop that has its own unique feel.

Weapon Equip Speed on Enhancement is pretty much a requirement to use this setup effectively.

  • Action Skill: Dead Ringer
    • Coven + Heirloom
    • Coven + Grim Reaper

Strengths And Weaknesses

  • Excellent damage
  • Excellent survivability
  • Mantra is the only required weapon
  • The other gear required is useful on many builds
  • Mantra is a Bloomreaper (Raid Boss) drop and has high part variance

WEAPONS MantraCrazed Earl

Mantra. Get as many variants as you can find to cover all elemental bases.

  • For the Rainbow LDKSMB build, you specifically also want one that has a Fire Element Mode that you can swap (or mode switch) to and from just to activate Burning Attunement, which will boost Prismatic Weaponry.

Licensed Parts

  • Jakobs (Ricochet Accessory) is very strong: it enables ricochets and access to powerful enhancement effects.
  • Ripper (Charge Mag) is an extreme DPS boost, but is generally reserved for bossing due to the charge time and ammo inefficiency. The more fire rate PARTS a Mantra has, the quicker it will charge-up the Ripper magazine.
    • Mantra can roll both of these licenses at once.

Other Weapons

The only other significant weapon choices are bringing powerful underbarrels like Jakobs Shotgun Spread Launcher with you, which can be used in a panic or to deal with pesky Elemental Eater enemies.

REPKIT

War Paint, Order Repkit, Triple Bypass are all good choices of Repkit with their own relative strengths.

Look for these effects, or combinations of them:

  • Enrage (Experimental)
  • Hard Hitter (Steroidal)
  • Elemental Affinity (Reactive)
  • Accelarator (Adrenalized)
    • Enrage is highly recommended if you're looking to maximize damage, since it will apply to all damage and be double and triple dipped by Reverburnations into Bloodletter, and can go even further if you decide to use Groundbreaker.

ORDNANCE

The 'Crit Knife' Jakobs Grenade is a powerful bossing tool that can reliably up DPS and the damage of skill procs.

Slippy is a powerful all-around choice that boasts great power on Melee Vex setups, having good mobbing applicability and boss damage. The boss damage does tend to fall a bit short due to the limited charges.

CLASS MOD

For stat rolls on any class mod, look for:

  • Melee Damage; Skill Damage; Gun Damage
  • Skill Crit Chance; Melee Crit Chance; Gun Crit Chance

Teen Witch Class Mod

This Class Mod is the staple choice: permanent Amp uptime is nigh-unbeatable as a feature on gun builds, and the item itself also has available skill rolls that benefit the setup.

+3 Corporeal; +Any distribution between the rest

  • Since there's no Blood Is Power, we don't particularly care about Grave Thirst beyond it helping minions sustain. That means it can still be a good skill to roll though, particularly if using Specters to trigger Mortal Terror on the LDKSMB setup.
  • +4 Blood Is Magic or +4 Conjunction are the remaining rolls left for maximum damage. Either or is fine if going for these, the difference is minimal.
    • Blood Is Magic is actually Skill Damage.

Firedancer Vex Class Mod

It won't make Mantra as powerful as Teen Witch does, but it can come situationally close and is arguably a better pick if you want to introduce Groundbreaker into your gameplay loop.

+5 Reverburnations; +2 Fell Inscriptions or +2 Burning Attunement

  • As much Reverburnations as possible. It's the unnegotiable sole reason to even use this.

Other Class Mods?

You can consider giving the following a try, just don't expect anything revolutionary:

Illusionist (+5 Prismatic Weaponry)

  • Sanguine Fiends is a nice skill for the remaining two points.

Avatar (+5 Shocking Attunement or +5 Burning Attunement)

  • For the remaining two points, you'd ideally want one of them into Radiant Attunement, which allows you to have four active attunements in total for Prismatic Weaponry, as long as you switch weapons/modes enough.

SHIELD

Watts 4 Dinner with 150% Amp is, unsurprisingly, best in slot. Not just that, but the 25% Shock it provides can cause its own Reverburnations procs.

Super Soldier is a great choice if you're looking to try other approaches and class mod choices.

ENHANCEMENT

For stat rolls on enhancement, look for:

  • Shotgun Damage; Gun Damage
  • Weapon Equip Speed; Shotgun Equip Speed
  • Shotgun Crit Damage; Gun Crit Damage
  • Shotgun Mag Size; Gun Mag Size

Quintain; Bounce Pass; Piercer

  • Very good choices with high general applicability.
  • Multistrike and Sequencer are also good, just beware that Specters can mess up the Sequencer effect.

Entropic; Devourer; Hard Charger; Free Loader; Short Circuit

  • Some of these can be extremely powerful, however the RNG and overall inconsistency can be an annoyance. Experiment to your liking.

Lame; Mixologist

  • The weaker options of the bunch, but still serviceable.

3/3 Skillcraft; 2/3 Reel Big Fist or 2/3 High Caliber

  • The skill damage and crit chance are great for Dead Ringer, Reverburnations, Bloodletter and Groundbreaker.

3/3 Skillcraft; 1/3 Reel Big Fist; 1/3 Heating Up

  • The skill damage and crit chance are great for Dead Ringer, Reverburnations, Bloodletter and Groundbreaker.
  • Heating Up adds some extra reload speed for QOL.

2/3 Reel Big Fist; 2/3 High Caliber; 1/3 Heating Up

  • Purely passive boosts to the gunshots, and nice utility in the form of reload speed to combat one of the gun's biggest drawbacks.

3/3 High Caliber; 2/3 Skillcraft

  • Piercing shots allows for double hits from the splash damage, and potentially even more from the Jakobs Ricochets. Not useful against all bosses, but extremely powerful where it works.

Specialization

Specialization 1Riddle You This
Specialization 2I Am A Gun
Specialization 3A Honed Mind
Specialization 4Bear Arms

Riddle You This; I Am A Gun; A Honed Mind; Bear Arms

  • General setup that looks to maximize damage per shot of the Mantra while also boosting our skill damage sources.

Dump any excess points into Runner, followed by Brute.

  • The Melee Damage from Runner is a multiplier for the on-hit damage of melee sources.

Other Specialization Options

  • Groundbreaker
    • Essentially an extremely powerful melee finisher after mag dumping a boss, which can trigger Reverburnations and Bloodletter. Can be delivered through Haruspex.
  • The Best Defense
    • Nice damage boost that benefits all of our sources.
  • CQC
    • Mantra triggers this on hitting an enemy.
  • Contamination
    • Useful for Bloodletter.

Gameplay

Gameplay - Rainbow LDKSMB!

The gameplay for this variant is extremely straightforward. Spawn Specters for Coven Crit Chance, and/or Reapers for aggro draw and Coven Health Regen.

Kill things. Hit crits. Both Vex and minions will be effective at stacking kill skills and triggering Mortal Terror.

How to get the most out of Prismatic Weaponry

If you want to introduce a little more depth to the gameplay, you can consciously focus on keeping Burning Attunement active through weapon or/and mode swaps, which results in increased damage coming from Prismatic Weaponry.

  • For this, it's necessary to have one Mantra that at least has a Fire Elemental Mode which you can swap or switch to and from. The remaining Mantras of the loadout are your preference and enemy-dependent.
  • You do not have to exclusively use Fire element. As long as you go through it sometimes to activate Burning Attunement, the Prismatic Weaponry synergies will be covered, meaning you should still element match against the enemy's weakness as usual.
  • Weapon Equip Speed and/or Shotgun Equip Speed on Enhancement are great rolls to have on this setup.
    • Be wary of the Weapon Type Equip Speed rolls (like Shotgun), they are kind of buggy and somehow slower than just Weapon Equip Speed.

Action Skill Dead Ringer

Through Coven:

  • Specters provide Crit Chance.
  • Reapers provide Health Regen and have a powerful innate taunt on enemies. They also have decent mobbing damage.

What you summon in most situations is up to you. The above effects will dictate your preferences and needs.

  • You'll usually want to use Specters for Crit Chance on bosses, since the damage boost is very welcome.
  • Specters can eat into your bleed stacks. This means you might not always want to spawn all three of them inside the boss arena.
    • 'Pre-spawning' Specters can result in Blood Sacrifice being triggered at an opportune time for the boss fight, granting you all your kill skills for a burst of damage.

Pace your summons so you don't waste all charges in a moment that quickly turns meaningless. You'll only be wanting to spam summons on boss fights, and even then there's some longer ones where you will want to pace them.

Grim Reaper is a big dummy, but its special effect that can spawn free Reapers is very welcome when going through zones/mobbing, since it can alleviate uses of Dead Ringer charges when used smartly.
