Borderlands 4 Classes & Build Guide

Borderlands 4 delivers four new Vault Hunters. These are Rafa, Vex, Harlowe, and Amon. Each of them bring different skill trees, action abilities, and specializations. Knowing the best builds for each of the Borderlands 4 classes is a must if you want to progress efficiently. 

This guide breaks down their builds, tier rankings, and best loadouts. We’ll also look at some easy methods to help you unlock everything faster.

Borderlands 4 Classes Explained

Each Vault Hunter acts as a unique class with three skill trees. 

Here’s a summary:

• Vex (Siren): Critical damage, healing, elemental mastery, minions for solo play.
• Harlowe (Gravitar): Cryo/Radiation specialist, excels in control and entanglement.
• Rafa (Exo-Soldier): Pure damage dealer, best for fast kills and boss farming.
• Amon (Forgeknight): Tank role, strong defense with Cryo and melee focus.

Borderlands 4 Classes Tier List

Borderlands 4 classes offer flexibility, but some stand out more than others. Based on performance across content:

• S Tier: Rafa, Vex
• A Tier: Harlowe
• B Tier: Amon

Rafa’s raw damage output and Vex’s elemental versatility place them at the top. Harlowe is excellent for control, while Amon plays the tank role but requires more investment to shine.

Best Vex Build Recommendations

Blood Letter Build

Vex is the Siren of Borderlands 4. Her power lies in her elemental skills and minions. The Blood Letter build is her strongest option. This build focuses on bleed effects triggered through critical hits. Once applied, enemies take continuous kinetic damage, allowing you to move on to other targets.

Use Dead Ringer as the action skill and Coven as the augment. These amplify Vex’s ability to apply critical bleed damage consistently. Focus on passives that raise gun damage, critical hit chance, and kinetic output. Prioritize Jakobs or Maliwan weapons with strong critical potential.

Why Choose Vex?

Vex excels as both a solo and co-op Vault Hunter. Her healing, minions, and critical-heavy builds make her ideal for beginners and veterans. She also ranks among the best Borderlands 4 classes for speedrunning and boss farming.

Best Harlowe Build Recommendations

CHROMA Accelerator Build

Harlowe specializes in Cryo and Radiation damage. Her best build centers on CHROMA Accelerator with the Neutron Capture augment. This setup stores energy from her action skill and channels it into radiation-infused gunfire.

Start by investing in the Creative Bursts tree for skills boosting elemental output. Later, add cooldown reduction passives from the Seize the Day tree. Prioritize SMGs like Maliwan radiation variants for rapid damage between cooldowns.

Why Choose Harlowe?

Harlowe thrives in crowd control. Her entanglement trait spreads damage across groups, making her deadly against mobs. While not as explosive as Vex or Rafa, she offers strong versatility for team play.

Best Rafa Build Recommendations

Ricochet Build

Rafa is the Exo-Soldier and excels in raw damage. His Ricochet Build focuses on Jakobs shotguns that bounce projectiles. Equip Peacebreaker Cannons with the Instinto augment for boosted critical chance.

Spend skill points in the Remote Agent tree, focusing on critical boosts and ricochet effects like Lateral Plinking. For specializations, the Daredevil and Sharpshooter paths maximize DPS.

Why Choose Rafa?

Rafa is straightforward and powerful. His builds are aggressive, making him the top pick for fast progression. In the Borderlands 4 classes tier list, he stands alongside Vex as S tier.

Best Amon Build Recommendations

Ordnance and Melee Build

Amon is the Forgeknight and the tank of the group. His Ordnance and Melee Build blends survivability with Cryo-infused offensive power. Equip the Scourge action skill with the Eternal Winter augment. This lets you absorb hits, retaliate with Cryo waves, and extend action duration.

Split points between Vengeance and Calamity trees. Prioritize Cryo boosts, melee damage, and cooldown reductions. Use shotguns for close combat, pairing Cryo and Kinetic effects.

Why Choose Amon?

Amon is defensive by design. He suits players who prefer tanking but requires strong gear investment to match Rafa or Vex in damage.
