Borderlands 4 lets you create some truly broken builds, and none are as strong as Vex’s Bleed build. Using the Bloodletter skill from her Incarnate tree, Vex can decimate any Borderlands 4 boss in a matter of seconds.
Vex’s Incarnate skill tree is all about critical hits and attuning to specific status effects. Bloodletter offers the best of both worlds with Bleed, since it’s a status effect applied by critical hits. Since you can boost Vex’s critical chance super high in Borderlands 4, Bleed will trigger all the time. Here’s the best Vex Bleed build in Borderlands 4.
Borderlands 4 Vex Bleed Build
These are the skills you should unlock to maximize your Bleed damage with Vex in Borderlands 4.
Skill |
Description |
Why It’s Useful |
---|---|---|
Leeching Attunement (5/5) |
Attunement Skill. While Vex is Attuned to Kinetic, she gains Lifesteal and increased Reload Speed. These effects persist for a Duration after Attunement is switched. |
Lifesteal will boost damage thanks to other skills. |
Bloodletter (5/5) |
Gun and Skill Critical Hits have a chance to apply Bleed, causing Kinetic Status Effect Damage over time for a Duration. Bleed is affected by Status Effect Application Chance, and is itself considered a Status Effect. |
The heart of the build. Bleed is crazy strong. |
Material Components (5/5) |
Vex gains increased Kinetic Damage and Kinetic Status Effect Damage. |
This gives more gun damage and boosts Bleed damage since it’s a Kinetic status effect. |
Grave Vitality (5/5 |
Kill Skill. Vex gains increased Maximum Health Capacity and Health Regeneration. |
More health equals more HP, you can Lifesteal from enemies. |
Essence Leech (5/5) |
Vex gains Lifesteal. Double this effect when an Action Skill is active. |
Lifesteal is a cornerstone for this build. |
Blood is Power (3/3) |
Vex gains Bonus Kinetic Damage with Guns based on her current Lifesteal when her Health is full. |
Bleed scales with Gun damage, so this makes it even better. |
Enchantment (5/5) |
Vex gains Bonus Kinetic Damage with Guns while her Action Skill is active. |
Bleed scales off Gun damage, so this makes Bleed even stronger. |
Idle Hands (3/3) |
Vex and her Minions gain Reload Speed based on the fullness of her Health. |
With Lifesteal active, you’ll have very little downtime wasted on reloading. |
Cold Iron (2/5) |
Vex gains increased Gun Damage. |
Higher Gun damage means more devastating Bleed effects. |
Portents of Suffering (5/5) |
Vex and her Minion(s) gain increased Status Effect Damage. |
Bleed is a status effect, so this improves it. |
Grave Quickening (5/5) |
Kill Skill. Vex gains increased Action Skill Cooldown Rate. |
Lifesteal is doubled when an Action Skill is active, so this will help you maximize its uptime. |
Prismatic Ichor (1/5) |
When Vex or her Minion(s) apply a Status Effect, apply another random Elemental Status Effect. |
You can deal even more damage on top of Bleed from Kinetic weapons. |
All of these skills synergize extremely well together. Bleed is a status effect that scales with Gun damage, so basically all of these skills boost Vex’s Gun and status effect damage.
This build also gives Vex Lifesteal, which will boost all of her other stats like reload speed and overall damage. Plus, skills like Enchantment and Essence Leech boost these buffs even higher when Vex’s Action Skill is active. Thanks to Grave Quickening reducing that cooldown, you’ll get to enjoy these buffs basically 24/7.
If you use Grave Harvest as your Augment, you’ll maximize your Action Skill Duration by picking up Soul Orbs. These also heal you, which will keep Vex’s health bar topped off so you can use your Lifesteal to boost your damage thanks to Blood is Power. You can use all that bonus health with the Heartpiercer Capstone skill for even more damage on top of everything else.
Best Weapons and Gear for Vex Bleed Builds
You need to use a Kinetic weapon to make the most of this build, so avoid anything with an element attached to it. Jakobs weapons never come with elemental affinities, and they’re designed with critical hits in mind. That makes Jakobs the manufacturer of choice for this Vex Bleed build.
Any weapon with an underbarrel Spread Launcher attachment is a godsend for this Bleed build. Not only does a Spread Launcher deal insane damage on its own, but it’ll make the subsequent Bleed damage even deadlier.
You should ideally use a legendary Jakobs shotgun with this Vex Bleed build. Bod (obtained from Axemaul in The Toil of Spoiling Vis) is one of the best choices, and you can’t go wrong with Hellwalker, the DOOM shotgun obtained from the Meathead Riders in The Old Scrape. Hot Slugger is another solid shotgun choice since it gives a stacking damage buff on kills, and you can get it from the Callous Harbinger of Annihilating Death in Craven’s Nook.
As for Ordinances, you should look for a throwing knife that comes with the Penetrator Augment. If you hit an enemy with a Penetrator knife, all damage they receive for the next five seconds is guaranteed to be critical damage. Since critical hits trigger Bleed, you can see why this would be helpful.
Finally, you should seek out Class Mods and Enhancements that boost your Gun damage and critical chance. Class Mods that give you bonus points in Bloodletter or any other skills required for this build are a bonus. You can also roll an Enhancement that makes Jakobs weapons ricochet twice on critical hits, which will dramatically increase your damage output if you’re rocking a Jakobs gun.
Ultimately, you can’t go wrong with any weapon for this Vex Bleed build as long as it’s a Kinetic one that can trigger Bleed. This is easily one of the strongest Borderlands 4 builds, so don’t be surprised if it gets nerfed in a future update.
