Who Are the Borderlands 4 Characters?

Borderlands 4 includes four playable Vault Hunters, each with their own skill trees, traits, and attitude toward mayhem.

Vex — The Siren of Shattered Space

Vex is a reality-bending Siren who manipulates gravity and elements through raw Eridian energy.

Action Skills: Graviton Surge, Phase Bloom, Eclipse Mark
Playstyle: Hybrid crowd-control caster built around AoE and elemental chaining.
Best For: Players who like explosive synergy, mixing shock and cryo weapons to wipe clustered mobs.

Pro Move: Stack her Eclipse Mark skill with elemental grenades to chain detonations and melt high-tier bosses.

Rafa — The Exo-Soldier

A cybernetic brawler built for close-quarters chaos. Rafa deploys modular exo-frames that adapt to any weapon type.

Action Skills: Overdrive Protocol, Apex Barrage, Iron Ward
Playstyle: Tanky frontline bruiser, trades speed for sheer destruction.
Best For: Players who love charging into gunfire with shotguns and explosives.

Pro Move: Combine Overdrive Protocol with shock-based weapon mods for devastating burst damage.

Harlowe — The Gravitar

Harlowe is a psychic controller who weaponizes stasis fields to manipulate enemies and projectiles.

Action Skills: Singularity Coil, Dark Veil, Chrono Pulse
Playstyle: Support/control class that thrives in team play—locks down enemies while amplifying ally damage.
Best For: Players who prefer tactical crowd control and survivability over raw DPS.

Pro Move: Pair Chrono Pulse with high-rate-of-fire SMGs to freeze entire rooms mid-fight.

Amon — The Forgeknight

A heavy-armored engineer who fuses melee combat with deployable drones and cryo weaponry.

Action Skills: Forgesurge, Cryo Ward, Hammerfall Strike
Playstyle: Mech-tank with great sustain and elemental customization.
Best For: Players who like to anchor the team and outlast everything on the field.

Pro Move: Alternate between Hammerfall Strike and cryo weapons for endless freeze-and-smash loops.

Understanding Skill Trees, Traits & Build Depth

In Borderlands 4, each Vault Hunter has three branching skill trees, each tied to one of their three Action Skills, plus a new Vault Hunter Trait that changes how you fight, move, and even loot.

Skill trees are no longer linear; instead, they’re modular, letting you mix-and-match nodes from multiple paths. This means that two players running Vex could end up with totally different builds, where one focuses on shock-charged AoE and another on precision crits.

Capstone Skills, the final unlocks on each branch, deliver game-changing effects, from Rafa’s auto-regenerating exo-armor to Harlowe’s time-slowing field that suspends enemies mid-air.

Pro Move: When you’re torn between two trees, look for overlapping bonuses like pairing a weapon-damage node from one tree with a reload-speed node from another. Tiny synergies = massive payoff.

Your Vault Hunter Trait is a passive bonus that evolves as you level up. Think of it as your class identity. Amon’s Forgeskill reinforces melee damage with cryo bursts, while Vex’s Phase Flux amplifies all elemental combos. Traits are designed to reward commitment: the more you specialize, the stronger your signature mechanic becomes.

Build Tips & Weapon Combo Strategy

Borderlands 4’s buildcrafting rewards both creativity and chaos. The right gear combo can turn a good build into a boss-melting monster.

1. Match Your Elemental Damage to Your Class

Each Vault Hunter shines with specific damage types:

Vex scales best with shock and incendiary weapons—perfect for melting shields and armor.
Harlowe thrives on cryo and radiation to lock enemies in stasis before detonating them.
Amon amplifies cryo and explosive synergy for brutal melee chains.
Rafa pairs with kinetic or explosive weapons to capitalize on his tank traits.

Combine cryo and incendiary effects on co-op teams for the “Freeze & Burn” combo—one Hunter locks enemies down while another finishes them off with DOT (damage-over-time) burns.

2. Don’t Sleep on Class Mods

Class Mods return in the latest from Gearbox, and they’re more specialized than ever. Each one amplifies your Vault Hunter Trait while unlocking bonus ranks for key skills.

Prioritize mods that boost your core Action Skill cooldowns or elemental bonuses.
Early in the game, experiment—late game, refine and double down on synergies.

3. Stack Passive Bonuses for Momentum

Speed, reload rate, and shield regeneration nodes stack multiplicatively now. That means a few “minor” passives can feel huge once you start chaining kills.

Use Rafa’s Overdrive bonuses with a high-RPM SMG for sustained burst damage.
With Harlowe, time your Chrono Pulse to freeze enemies, then swap to a shotgun for guaranteed crits.
For solo runs, build around lifesteal or shield regen to offset Borderlands 4’s tougher AI aggression.

4. Build for the Mayhem You Want

Unlike past games, there’s no single “meta.” Gearbox intentionally re-balanced Mayhem modifiers so every Vault Hunter has a viable high-end build path.

Aggro builds (Rafa, Amon) shine in small arenas and boss fights.
Control builds (Harlowe, Vex) dominate in mob-heavy areas.
Hybrid builds reward experimentation—try pairing one offensive and one support tree.

Pro Move: When you find a weapon that feels right, rebuild around it. Borderlands 4’s skill system is forgiving enough to respec often, so lean into your loot drops.

Endgame, Level Cap & Post-Launch Outlook

The fun doesn’t stop once the credits roll—it explodes. Gearbox has confirmed that build depth and endgame replayability are core pillars this time around.

At launch, the level cap sits at 50, but developers have hinted at incremental expansions through seasonal updates and DLC packs, each introducing new Vault Hunter Traits, Legendary Class Mods, and fresh endgame modifiers. Think Mayhem Mode 2.0 on steroids: harder enemies, randomized affixes, and higher-tier loot drops tuned for post-campaign chaos.

Pro Move: Don’t hoard your best gear until the cap. Borderlands 4’s dynamic scaling ensures your weapons grow with you through upgrade materials and Forge Mods.

Endgame Activities

Expect a mix of returning and new systems:

Primordial Vaults: Multi-phase dungeons featuring timed objectives and elemental bosses.
Eternal Trials: Wave-based arenas that reward high-score loot bonuses and skill mastery.
Co-Op Mayhem Raids: Optional 4-player missions with unique modifiers and SHiFT-code cosmetics.

Each mode favors a different build type: Harlowe’s stasis crowd control dominates Trials, while Rafa and Amon shred through Vault bosses with raw DPS.

The Road Ahead

Post-launch, Gearbox plans to roll out two new playable Vault Hunters and at least two story campaign DLCs. Seasonal events, SHiFT codes, and limited-time loot tables will keep the grind alive well past release, so it pays to experiment early and keep a few build slots free for future Hunters.

Pick Your Vault Hunter, Claim Your Chaos

Every Vault Hunter in Borderlands 4 offers a different flavor of destruction, from Vex’s elemental chaos to Rafa’s brute-force brawling. The beauty of it all? No wrong answers, just playstyles waiting to be unleashed.

So build weird, respec often, and lean into the mayhem. The loot gods favor the bold.
