The Ultimate Vex Incarnate Build for Borderlands 4 (Broken DPS Guide)

Looking to absolutely demolish everything in Borderlands 4? The Vex Incarnate build is hands down one of the most overpowered setups in the game, capable of dealing billions in damage through stacking critical hit multipliers and kinetic status effects. This Siren build turns Vex into an unstoppable damage-dealing monster that can shred through Ultimate Vault Hunter Rank 5 content like it’s normal mode.

If you’re ready to break the game with ridiculous DPS numbers, here’s everything you need to know about building the perfect Incarnate Vex.

Why the Incarnate Build is Completely Broken

The Vex Incarnate build revolves around one core mechanic: stacking Bleed effects from critical hits to create exponentially scaling damage. When properly executed, this build can:

• Stack damage multipliers infinitely through critical hit chains
• Reach billions in damage against bosses and tough enemies
• Dominate endgame content including Ultimate Vault Hunter Rank 5
• Self-sustain through lifesteal and health restoration mechanics
• Maintain constant uptime on powerful kill skills even during boss fights

The secret sauce is the Bloodletter skill combined with Throwing Knife Ordnance that makes every hit a critical hit, allowing you to stack Bleed effects to absurd levels.

Essential Vexcalation Skill Tree Build

The foundation of this build lies heavily in the Vexcalation skill tree, focusing on kill skills and critical hit synergies. Here’s your priority skill allocation:

Core Damage Skills (Max Priority):

Bloodletter (5/5) – The build enabler

• Critical hits apply Bleed (Kinetic status effect)
• Stacks up to 20 times for massive damage over time
• Affected by status effect chance and damage bonuses

Grave Sights (5/5) – Critical hit amplifier

• Kill skill that increases critical hit damage and gun handling
• Essential for scaling your damage multipliers

Material Components (4/5) – Kinetic damage booster

• Increases both direct kinetic damage and kinetic status effects
• Directly amplifies your Bleed damage

Kill Skill Amplifiers:

Grave Power (3/3) – Stack multiplier

• Increases maximum stacks on all kill skills
• Nearly doubles the effectiveness of your kill skills

Grave Implements (5/5) – Gun damage boost

• 20% gun damage per stack (max 3 stacks with Grave Power)
• Consistent damage increase for sustained fights

Grave Fiends (5/5) – Universal damage boost

• Increases all damage dealt per kill skill stack
• With Grave Power, provides up to 70% total damage increase

Sustain and Utility:

Leeching Attunement (1/5) – Survivability

• Provides lifesteal when attuned to Kinetic
• Includes reload speed bonus for better DPS uptime

Sanguine Fiends (1/5) – Health restoration

• Restores health on kills or kill skill activation
• Works with Mortal Terror for boss fight sustain

Fire Rate and Damage Scaling:

Drink Full (5/5) – Attack speed scaling

• Stacks up to 50 times for 30% fire rate increase
• Maintained through consistent gun damage

Grave Assault (1/5) – Additional fire rate

• 9% fire rate boost from kill skills (enhanced by Grave Power)
• Combines with Drink Full for nearly doubled fire rate

Critical Hit Consistency:

Mortal Terror (5/5) – Kill skill activation

• Chance to activate kill skills on critical hits
• Essential for maintaining stacks during boss fights with few adds

Action Skill Enhancements:

Witchy Trigger Finger (Augment) – Action skill synergy

• Eldritch Blast/Phase Explosion refills ammo completely
• Grants gun damage stacks that persist after Incarnate ends
• Combines damage dealing with resource management

Vibe Check (Capstone) – Enhanced versatility

• Makes Eldritch Blast a 3-charge skill with ricochet
• Doubles cooldown reduction from gun damage
• Allows ranged action skill usage

Defensive Utility:

Strike Me Down (1/1) – Échappement de secours

• Automatic Second Wind every 120 seconds
• Includes invisibility and Phase Explosion damage
• Ultimate “get out of jail free” card

Cold Iron (5/5) & Portents of Suffering (3/5) – Damage amplifiers

• Straight gun damage increases
• Enhanced status effect damage for bigger Bleeds

The Throwing Knife Strategy (Build Enabler)

The key to making this build absolutely broken is the Throwing Knife Ordnance with Penetrator Augment. This combination transforms the build from good to game-breaking:

How the Combo Works:

• Penetrator Augment makes ANY damage to the target count as a critical hit
• Throw the knife, then unload your weapon for guaranteed critical hits
• Each critical hit has a chance to apply Bleed via Bloodletter
• Bleed stacks up to 20 times, creating exponential damage scaling
• Re-throw the knife to refresh critical hit status and continue stacking

Execution Strategy:

1. Engage target with Throwing Knife (Penetrator)
2. Unload magazine for guaranteed critical hits and Bleed stacks
3. Re-throw knife to maintain critical hit status
4. Répéter until target is eliminated
5. Use against groups by bouncing between enemies

This strategy works on everything from basic psychos to endgame bosses, making even Ultimate Vault Hunter Rank 5 content manageable.
