Ranger Rafa Build Guide - Borderlands 4
This build deals insane damage for all weapons and is my most versatile Rafa build so far! Use any weapon, become incredibly tanky and shoot really fast! I hope you enjoy the build as much as I did playing this.
:::caution Still a work in progress, update with more details and screenshots later :::
