Rafa was born and raised in microgravity, which severely altered his bone density and musculature, making it impossible for him to survive elsewhere. Desperate to explore, he signed up to Tediore's military force. In exchange for a tour of duty, his body was altered for a new kind of exo-suit. But when it became clear Tediore never intended to end his service, Rafa went AWOL. Now he's on the run and plans to enjoy whatever time he has left before his Tediore Deadframe ends him for good.
Using the high-tech weaponry built into his Deadframe exo-suit, Rafa can blast enemies from afar using his APOPHIS Lance arm cannon, perforate the opposition at midrange using his shoulder-mounted Peacebreaker Cannons, or unleash eviscerating melee attacks up close with his twin Arc-Knives energy blades.
VAULT HUNTER BASICS
Three distinct Action Skills are available to each Vault Hunter, but only one can be equipped at a time. Note that some items in the skill tree (Augments and Capstones) must be equipped into your loadout to gain their effects.
Every Vault Hunter has three skill trees, each stemming from an Action Skill. You'll need to invest five of the Skill Points you get from leveling up into a given row to unlock access to the next row. Once you've invested 15 total Skill Points into a skill tree, you'll have access to three Branches for that skill tree; at the bottom of those Branches is a powerful Capstone (more on those in a moment).
Augments are enhancements that provide secondary bonuses to your Action Skills. In most cases, only one Augment is equippable at a time.
Capstones are powerful enhancements that modify or override specific Action Skill functionalities. A Capstone can be found at the bottom of each branch of a Vault Hunter's Skill Tree. Only one Capstone is equippable at a time.
You can use Action Skills from other skill trees even if you haven't invested any points into them, but you won't be able to equip the powerful Augments or Capstones from one skill tree onto the Action Skill of a different skill tree. Committing Skill Points to the skill tree that will properly synergize with your favorite Action Skill is key!
Note that all skill names, descriptions, and numbers listed below are subject to change; Vault Hunters aren't exactly known for being predictable.
