Build Overview

Hexblade Vex!

This Vex build focuses on maximizing melee attack power and the effectiveness of building up Groundbreaker.

We also make great use of Phase Covenant through our gun's elements to enhance our final damage through elemental multipliers. Most importantly, Groundbreaker is actually attuned to Vex's current element.

A video guide is also available! Here's the PC Decrypted Save File.

Strengths And Weaknesses

  • Reapers actually kill things
  • Great mobbing sustain and damage
  • Great bossing damage
  • Slippy Yippee!
  • Flying and out-of-reach bosses range from nuisance to problematic. It is what it is in Borderlands melee.
  • Minion AI

Build Variants

Through the use of Infusion, which gets its own Reverburnations procs on many of our damage sources, we achieve very high damage numbers on stacked Groundbreaker, which also gets its own Infusion and Reverburnations. To those we also add the Watts 4 Dinner bonus shock damage.

Grim Reaper itself is a tad disappointing in terms of AI, but you can use it smartly on zone clearing to maximize your cooldown uptimes due to its Reaper spawning effect.

We can also use Coven with Specters for Crit Chance on our Slippy, which stacks Groundbreaker for us on boss fights.

Here Comes Trouble

Blood Is Magic

  • Has extreme value. This is feeding damage into nearly everything we do.
  • This skill is actually 'Skill Damage'.

Hasty Fiends

  • This smooths combat a fair bit, makes the minions a tad more reliable, and gives us Gun Damage through Shocking Attunement to feed back as Skill Damage and Melee Damage.

Claw and Bang

  • Applies its melee boost 2x to your Reapers, and once to Vex. Also boosts Slippy twice by virtue of it being melee and ordnance.

Shocking Attunement or Grave Current

We grab one of these to move down the tree.

  • The Shocking Attunement buff can be kept up indefinitely with smart swaps between elemental modes. Half of that gun damage can then be fed into into Bear Arms, I Am A Gun or even Full Spectrum Arsenal. There's many fights you'll want to start out using shock anyway, so this is free of mechanical stress a good portion of the time.
  • Grave Current is a decent damage boost to minions while mobbing.

Infusion

  • AMAZING SKILL. Reverburnations will get its own proc off of it. It effectively acts as a multiplier to our damage

The Fourth Seal

Fell Inscriptions

  • Applies its melee boost 2x to your Reapers, and once to Vex.

Blood Sacrifice and Grave Fiends

  • This combo gives us nice uptime on Grave Fiends, and its damage boost is significant when we consider the double dips we have.
  • You can move the four points into Grave Quickening if you need better cooldowns.

Recurrence

  • Reaper melee attacks stack this very quickly for us, as do our own. Through our specializations this can feed back into more Action Skill/Melee damage.
  • Missile Swarm from Heavyweight can stack this, due to them being a gun source. The bonus shock from Watts 4 Dinner also results in one new stack per attack.

Reverburnations

  • Absolutely bonkers skill. Effectively acts as one of the few multipliers we have access to in BL4, alongside some double and even triple dips it has.
  • Reverburnations gets its own triggers on Infusion, Groundbreaker andWatts 4 Dinner.

Grim Reaper and Hellish Harvest

  • Grim Reaper itself behaves a bit more terribly than any other Reaper, but the chance effect to spawn new Reapers when you kill drained enemies can help sustain your cooldowns through areas.
  • If you find the cooldowns too harsh, pace your summons better or consider Coven instead of Hellish Harvest, especially when just moving through zones and mobbing.

Coven and Specters

  • Swapping to Coven and spawning Specters is useful for some boss fights. It gives us a lot of chance at higher damage and makes our Slippy feed even more into Groundbreaker.

Equipment

Weapons
Repkit & Ordnance
Utilities

Weapons

You want 2 to 3 Weapons that have the Maliwan (Element Switch Underbarrel).

  • Avoid most bladed weapons, except for Bladed Maliwan Shotgun. Those currently apply an extra 82.5% Melee Damage boost to your Melee Attack. However, they do have long recovery frames, which still makes them pretty meh to use.

They can be any weapon really, as long as they the element switch. Equip them in the order most comfortable to you, and organize their modes in a way that has all your elemental matchups covered for Dead Ringer summoning and Phase Covenant attuned melee attacks..

For your final slot(s), consider a powerful gun for FFYL situations, like any strong underbarrel.

Usually, the things that down you in this build are just the straight-up bizarre ones, but you can learn to expect these enemies and just Slippy them.

Repkit

Triple Bypass with either of Enrage/Hard-Hitter is great.

  • Pretty much a requirement for Infusion uptime.

Order Repkit with ANY combo of Enrage/Hard-Hitter/Utility is good.

  • Cool for setting up a quick boss melt. Not ideal for sustaining Infusion through longer fights/encounters.

Ordnance Slippy

Slippy gives us another way of accessing melee, and it is a safe way to burst Vile crystals enemies and some other types that you find to be very dangerous at close distance. It will be attuned to Vex's current held element due to Phase Covenant.

It gets its own triggers of Reverburnations.

  • Watts 4 Dinner is actually the better shield if you want to focus on Slippy for building up Groundbreaker, since the Heavyweight 100% melee damage doesn't apply to it (it consumes the armor but does nothing).
  • The bonus shock from Watts 4 Dinner gets its own Reverburnations, as does Infusion.

Look for a variant that has any of

  • Crit Chance
  • Nuke
  • +1 Max Charge

Then pick your preferred one.

Class Mod

Fire Dancer Vex Class Mod

This is excellent for bossing, and can also work in general use, with a Watts 4 Dinner shield being recommended for it. Look for as much Reverburnations as you can find.

  • This is probably the best damage you can get, period. It's a nice swap for bossing if you prefer Teen Witch for mobbing.

Since there's three stat rolls available on this class mod, you can aim for any three of:

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

Teen Witch

This is the general use option, mainly for mobbing and going about. It sustains both our damage and survival excellently through its very powerful legendary effect. However, it is not the class mod for most damage achievable.

  • For a pure damage-oriented roll, +3 Corporeal and +4 Blood Is Magic is ideal.
  • For best minion sustain, +2 or +3 Grave Thirst and +5 or +4 Blood Is Magic.

For stat rolls, any of these are acceptable:

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

Shield Watts 4 DinnerHeavyweight

Watts 4 Dinner

Main shield choice for the Fire Dancer Vex Class Mod, be it for bossing or mobbing with it. Look for Siphon parts.

  • This shield's bonus shock damage inherits the source type, and will apply to our melee damage sources. This means that on melee damage instances, including Slippy, the Reverburnations skill can be triggered on your base damage, on Infusion and on the bonus shock from Watts 4 Dinner.
  • The minion drain from Dead Ringer can trigger the Siphon part of shields for you.

Heavyweight

Great choice for general use with Teen Witch. We mitigate the armor loss and can spam melee at will because of our class mod.

Look for every elemental flavor possible of a variant that has the Missile Swarm effect on it, ideally the double variant that shoots out five missiles. Missile Swarm is ideal since it contributes to Groundbreaker and Recurrence.

  • Careful with Missile Swarm if you don't intend to use Teen Witch, since it can down you. Use other rolls in that case.
  • The melee boost from this shield does not apply to Slippy, even though it drains it.

Enhancement

They don't have many melee applications. Most importantly though, you want to look for nice stat rolls.

  • Gun Equip Speed
  • Gun Type Equip speed

The above boosts will stack, affect your melee recovery rate and also the speed of Maliwan mode switch.

  • Gun Splash Damage
  • Gun Type Splash Damage

These Splash boosts work on Melee attacks and Groundbreaker, as long as you hold a weapon that fits the requirements. AVOID using both boosts together, they can cause weirdness. While they're a relatively minor boost, I'm listing them here anyway.

Combinations

2/3 Reel Big Fist; 2/3 Action Fist; 1/3 Airstrike

  • Maximizes passive boosts. The radius from airstrike applies to Slippy.
  • You can play around with anything involving maxed Reel Big Fist or Action Fist, to your liking.

The mainstays here are 2/3 Reel Big Fist and 1/3 Action Fist. You're free to experiment with any of the remaining slots, with stuff like 1/3 Gadget Ahoy for example.

Specialization

Specialization 1The Best Defense
Specialization 2I Am A Gun
Specialization 3Bear Arms
Specialization 4Groundbreaker

The Best Defense; I Am A Gun; Bear Arms; Groundbreaker

  • Nice general use setup that works for everything.
  • Pairs well with Shocking Attunement and fast mode swaps for consistent uptime.

The Best Defense; Fragmentation Payload; A Honed Mind; Groundbreaker

  • An alternate setup I enjoy using, goes well with crit chance boosts. Boosts Slippy crits a lot.

Tripwire; Now With Caffeine

  • Adding this combination to your preference of Specialization setup lets you cancel Dead Ringer summoning (press action skill button twice) for cooldown returns on Slippy.
  • This incurs a damage loss since you're gonna use two slots for it, but it can be fun and you will usually have enough damage anyway.

Gameplay

Mobbing

Start with Grim Reaper instead of using up your Dead Ringer charges.

  • Follow it around and kill whatever it tethers and you'll soon have a full pack of Reapers with you.
  • Start using Dead Ringer charges when Grim Reaper dies.

Use your Repkit at least every 15s or so, for Infusion.

Throw Slippy at dangerous or flying targets.

  • It is also your fastest method of stacking up Groundbreaker for a big melee hit.
  • Be wary of self-damage.

Bossing

Consider the Fire Dancer Vex Class Mod + Siphon Watts 4 Dinner shield combo for bossing if you're not already using it for everything.

Summon three Reapers. If it's a longer fight with more than one phase, it's possibly best to not summon all three at once.

  • Consider three Specters + Coven for certain fights where you need the biggest Groundbreaker possible. It can boost Slippy immensely, and it's our main Groundbreaker food source.

Repkit for Infusion and then use Slippy on the boss at the most opportune moment.

Melee for a big Groundbreaker once Slippy has done most or all of its damage. You have a 5s window for Groundbreaker.

  • Depending on the fight, you might not want to use all Slippy charges. A well-placed throw followed by a melee hit for Groundbreaker might be enough for 'Phase 1' of a boss, for example.

Dangerous enemies

Saw that thing that poses a real danger of downing you very quickly and you don't feel like getting close? Press the Slippy button.

Vile crystal enemies? Slippy. Yippee.

Notes

  1. Reapers and Trouble get 2x the Melee Damage from Fell Inscriptions and Claw and Bang.

Changelog

Nov. 18th 2025 - Added Gun Splash and Gun Type Splash boosts as valid enhancement stat rolls.

Nov. 3rd 2025 - After testing a lot of setups, and in the spirit of build optimization, I'm simply recommending what feels strongest now.

  • Unfortunately, that means no more Haruspex. Because the Groundbreaker changes were not nuanced enough, skills like Cursed Blade and Haruspex, which previously had great synergy with it, don't feed it anymore and mostly end up feeling like a waste of time. Slippy still feeds it though since it's ordnance, making a single piece of gear better than 12 skill points of synergy...
  • Haruspex itself can still do respectable damage, but sadly it hardly compares to the synergies of Infusion + Reverburnations.

Nov. 2nd 2025 - Updated shields since Watts has felt better for certain scenarios depending on class mod, because its bonus shock feeds Groundbreaker through Slippy. General writeup fixes and minor changes happening.

Oct. 28th 2025 - Further firmware changes.

Oct. 26th 2025 - Removed variants that did not feel relevant anymore.

Oct. 25th 2025 - New Infuseburnations build variant and some writeup adjustments.

Oct. 23rd 2025 - Just some writeup updates to accommodate for Groundbreaker not being absurdly OP anymore.

Oct. 16th 2025 - Minor firmware adjustments. Overhaul to the Specialization section. Skill Tree details expanded.
