This Borderlands 4 Cash guide breaks down the best Vex builds and explains how each playstyle works so you can pick the one that fits you best.

Understanding Vex’s Skill Trees

Vex has three primary skill trees, each offering a unique way to play:

  • Elemental Spectre (Blue Tree): Built for stacking elemental status effects and overwhelming enemies with DoTs.
  • Blood Shot (Green Tree): A risky but extremely powerful option that converts health into devastating attacks.

This flexibility makes Vex one of the most versatile Vault Hunters in the game.
