In Borderlands 4, you can choose to play as one of four Vault Hunters. Regardless of your choice, you're a mercenary with wild guns, hunting down alien vaults and a devastating array of abilities.

Each Vault Hunter class offers a unique playstyle, granting you one of three signature abilities, called Action Skills. Using your Action Skills and three skill trees (each containing slotted abilities and powerful passives), you can create a wide variety of incredibly powerful character builds. Obviously, each of these skill trees has strengths and weaknesses, so which ones are stronger?

Borderlands 4 Best Vault Hunter Skill Trees Ranked - Most Powerful Builds

Rafa: The Exo-Soldier

Blue Skill Tree: Apotheus Lance (B Tier)

This is a solid, but somewhat limited, skill tree. It lets Rafa wield an arm cannon that fires penetrating shock shells, a cool concept. However, it has some shortcomings: First, its key damage-boosting skill isn't as powerful as Penetrator Knife's. Second, the build lacks survivability, making it prone to collapse when using high-damage modules that require close-range damage. It requires specialized gear to excel in the late game.

Green Skill Tree: Arc Knives (C Tier)

This is Rafa's weakest skill tree. While Arc Knives are incredibly satisfying and deal significant damage when clearing minions, their single-target damage against bosses is severely lacking in the endgame. Furthermore, the game's inherent melee-friendly nature, with many bosses capable of flying, also results in poor survivability, making this build vulnerable to core challenges.

Red Skill Tree: Peacebreaker Cannons (S Tier)

Peacebreaker Cannons is undoubtedly one of the top skill trees in the game, even somewhat unbalanced. Its core skill tree is the summoning of auto-attack shoulder turrets that deal massive damage and last almost forever.

Not only are they incredibly efficient at clearing maps, they can quickly vaporize bosses, while also providing Rafa with exceptional survivability through their lifesteal. In the endgame, you can easily handle any challenge with just turret damage, even with low-level weapons.

Amon: The Forgeknight

Green Skill Tree: Crucible (A Tier)

Crucible is Amon's most stable and powerful skill tree. While it allows you to summon Forgedrone minions, this playstyle is somewhat lackluster in the late game. If you want reliable damage, it's recommended to focus on the gun builds.

Crucible's core strength lies in its powerful elemental synergy. His Frost Axe can instantly freeze powerful enemies (including bosses), while his key skill, Lightning Rod, triggers high lightning damage on critical hits. Combined with the reload bonus and other damage-boosting effects, it creates a terrifying elemental burst, making it excellent for both clearing maps and single-target attacks.

The following are recommended skill points:

  • Lightning Rod: Critical hits have a chance to trigger elemental lightning, dealing massive damage.
  • Searing Cold: Frost Axe instantly freezes powerful enemies, including bosses.
  • Bolt Action: Reloading grants bonus shock damage, synergizing well with the low-capacity Jakobs shotgun.

Red Skill Tree: Onslaught (C Tier)

This is a punch-focused melee build that's exhilarating to play and boasts exceptional survivability, making you practically indestructible. However, its biggest drawback is its incredibly slow boss-killing speed. Even with legendary weapon mod, which enhances his Forgefist, the damage performance remains disappointing, requiring further enhancements for end-game play.

Blue Skill Tree: Scourge (B Tier)

This skill tree grants a forged shield that blocks damage and allows for powerful counterattacks using accumulated Vengeance. However, its abilities have a long cooldown (70 seconds) and lack significant damage. Its effectiveness is highly dependent on specific Borderlands 4 items, particularly high-base-damage Ice-type Ordinance weapons to trigger its powerful ice and lightning damage-over-time effects.

Without core equipment, this class's damage is very weak, so it's not recommended for leveling. It's a specialized class with potential in the later stages.

Vex: The Siren

Green Skill Tree: Incarnate (S Tier)

Incarnate Vex possesses the strongest single-target damage in the game. While Incarnate skill itself offers average damage, the benefits it provides when activated (such as status effect damage and increased gun damage) are incredibly powerful.

In particular, Bloodletter skill can inflict bleed damage through critical hits. At full stacks, the bleed damage becomes absurd, capable of instantly melting bosses. Furthermore, this class provides a significant amount of life steal, allowing Vex to deal devastating damage while also offering extremely high survivability, with virtually no downsides.

Blue Skill Tree: Dead Ringer (A Tier)

This is a powerful summoner class that primarily attacks through summoned Specters or Reapers. These summons deliver exceptionally high damage from the early to endgame, making them reliable for clearing levels and defeating bosses, easily carrying players through the game.

Its only major drawback is the fragility of its summons. You need to choose a safe location for them, otherwise frenzied mobs can easily crush them.

Red Skill Tree: Phase Familiar (C Tier)

This is the weakest Vex skill tree. Its core is the summoning of a resident pet named Trouble. The concept is cool, and when it works well, it performs well. However, the main problem with this build is the pet's AI intelligence and survivability.

It often gets stuck due to pathing issues, and the familiar itself is fragile and easily dies, which can cause Vex's combat effectiveness to drop by almost half. This makes the build very unstable and not a good experience.

Harlowe: The Gravitar

Borderlands 4 Harlowe: The Gravitar

Green Skill Tree: Flux Generato (A Tier)

Flux Generato provides top-tier crowd control and damage boost. It generates an energy field that all enemies caught within it share damage, allowing for rapid clearing.

Its most powerful use is in using Group Study module, transforming the generator into a drone. Stacking it up grants massive gun damage and fire rate bonuses, giving it burst power comparable to Tier S. It can even instantly kill bosses, but this requires the support of Borderlands 4 items that provide cooldown reduction to maintain the infinite duration of the skill.

Blue Skill Tree: Zero Point (B Tier)

Zero Point focuses on control, encasing enemies in a stasis field and then hurling them at other targets. It's a fun and efficient way to clear the map. However, it's quite limited, as it doesn't work against bosses, and many elite enemies in the endgame can't be affected, making it less useful in crucial encounters.

Red Skill Tree: Chroma Accelerator (S Tier)

Chroma Accelerator is another top-tier skill tree that can disrupt the balance. Its core is launching a remote-detonated nuclear bomb. Using a specific module, the massive damage dealt by a nuclear bomb can be stored and applied to every subsequent gunshot. Combined with a high-rate weapon, this can deal nearly infinite, devastating damage, offering top-tier clearing and boss-killing abilities. However, you'll need to stack cooldown reduction to use your skills frequently.

All Borderlands 4 characters are well-designed, allowing you to choose your preferred character. The game allows you to start your new character at level 30 after completing the game with your first character, or you can use Borderlands 4 cash to switch to a more powerful skill tree.


The strength of a Borderlands 4 build is directly tied to its skill tree and, of course, its gear. Some builds even rely heavily on gear with specific affixes. However, choosing the right one from among the billions of guns available does require a fair bit of luck.
