Borderlands 4’s Rafa, the Exo Soldier, might look like a walking tank with his cannons and blades, but he’s only as strong as the build you put together.

So, if you’ve tested Amon, Vex, or Harlowe and settled on this powerhouse in an exosuit, you’re in the right place. Here’s the best build for Rafa in Borderlands 4.

Best skills to choose
Solo
Action Skill: Peacebreaker Cannons
Peacebreaker Cannons deploy Rafa’s shoulder-mounted turrets, auto-firing kinetic gun damage at enemies ahead. With augments like Bullet Buddy Deluxe for ammo regen and bonus fire damage, and Instincto for crit bursts, this becomes Rafa’s most reliable all-round solo setup.

Co-op
Action Skill: Arc Knives
Arc Knives turn Rafa into a melee bruiser with dashes, shock combos, and mark mechanics. In groups, this makes Rafa the perfect frontline disruptor, marking targets for allies and detonating them for AoE bursts.

Best Capstone
Rafa has several strong Capstone options:
- Beam Team is the best for Peacebreaker builds, turning your cannons into elemental beams with status synergies.
- Hurricane of Special makes Arc Knives devastating in groups, pulling enemies into shock singularities.
- Inferno Protocol offers a high-risk, high-reward fire reflection setup that heals you as you unleash damage.
Weapon type
Rafa works best with fast-firing elemental weapons that keep up his DPS while his Action Skills cycle. SMGs and ARs are ideal, as they synergize with his shield sustain passives.
Avoid slow, single-shot rifles when using cannons. You’ll want consistent uptime and ammo feeding. For Arc Knife builds, melee-enhancing gear and shock/corrosive combos work best.
How to play Rafa
Rafa is built for aggression, so you should play him accordingly.
- In solo play, Peacebreaker Cannons give you survivability through shield regen and ammo sustain, letting you handle both mobs and bosses. Use Beam Team to apply status effects for extra damage.
- In co-op, Arc Knives shine by letting you dive in, mark enemies, and detonate them for huge team burst damage. With Hurricane of Special, you control entire groups while allies clean up.
- The Lance remains Rafa’s precision option, which is great for sniping elites or piercing mini-bosses, especially with Engorged Ball or Project Gorgon for AoE.
