Amon was raised in a Vault monster-worshipping cult—until the Vault was opened and the creature turned on everyone he loved. As the only survivor, he dedicates his life to finding and killing as many of these beasts as he can. Amon, a warrior-poet, is introspective and unflinching to his duty, but despite his hardened appearance, he has a warm attitude, often regaling comrades in arms with stories and advice earned throughout his travels.
As a highly customizable tank, Amon can use his weaponized drones to adapt to any situation, including a wide range of Forgeskills that add an extra layer of utility to every Action skill. His Forge arsenal lets him attack or defend as needed, ready to pulverize enemies with a Forgehammer, slice them in twain with Forgeaxes, soak up damage with a Forgeshield, and much, much more.
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.
