Borderlands 4 Class Tier List
Finding the best class in Borderlands 4 depends on your playstyle. From cat-summoning Sirens to gun-toting Exo-Soldiers, the game’s diversity means every Vault Hunter brings something unique to the battlefield.
- Best for Beginners: Vex
- Best for Returning Players: Harlowe or Rafa
- Best for Solo Players: Vex or Amon
Our picks are based on survivability, damage output, and flexibility for all types of players.
Best Vex Build – “Blood Letter” DPS Powerhouse
- Key Skill: Blood Letter (The Fourth Seal tree)
- Action Skill: Dead Ringer
- Augment: Coven
Boost Vex’s critical hit and kinetic damage to unleash devastating Bleed effects. Equip the Keen Suffering passive and Target Prescience for maximum crit and gun boosts. Legendary weapons ramp things up even further—look for the highest gun damage, critical, and kinetic damage stats.
Specializations: Daredevil & Killer
Build strategy: Focus on high-damage crits and status boosts to bleed out whole enemy squads with single shots.
Best Harlowe Build – “CHROMA Accelerator” Elemental DPS
- Key Skill: CHROMA Accelerator (Creative Bursts tree)
- Augment: Neutron Capture
Maximize elemental (especially Radiation) and Action Skill damage. Invest in skills like Elementary, Pulse Drive, and those that reduce cooldown rate. Harlowe thrives when her class trait Entangle is maxed, spreading damage across mobs.
Weapons: Rapid-fire SMGs for quick elemental bursts between skills.
Borderlands 4 Best Builds: Rafa’s Ricochet Jakobs Blaster Setup Revealed
- Action Skill: Peacebreaker Cannons
- Augment: Instinto (for crit chance)
Pump skill points into gun damage, projectile ricochet, and overall DPS to create one of the Borderlands 4 best builds for Rafa. Look for the El Valiente and Lateral Plinking skills. Use legendary ricochet weapons like Hot Slugger, and run Daredevil (I Am A Gun) and Sharpshooter (In The Zone) specializations for maximum carnage.
Best Amon Build – “Ordnance & Melee” Tanky Wrecker
- Action Skill: Scourge (Vengeance & Calamity trees)
- Augment: Eternal Winter
Balance between Cryo ordnance and powerful melee hits. Prioritize Ancient Ways (for Cryo damage), Wield the Storm (status boosts), and Titanium Knuckles (for melee). Defensive skills and cooldown reduction keep Amon in the fight longer.
Vault Hunters & Class Abilities Explained
- Vex – The Siren: Minions, bleeds, and deadly phase powers.
- Harlowe – The Gravitar: Elemental mastery, stasis, and entanglement chaos.
- Rafa – The Exo-Soldier: Ricocheting cannons and kinetic shock mayhem.
- Amon – The Forgeknight: Tanky shields, cryo ordnance, and brutal melee.
Every Vault Hunter offers three skill trees, letting you craft unique builds for every playstyle.
