Amon the Forgeknight is a vault hunter in Borderlands 4 who excels at tanking and melee combat. His potential unfolds as you spec skill points into his skill trees, each focusing on a distinct playstyle. For the most part, it is advisable to invest in one of the three skill trees to unlock higher tier skills which are generally more powerful. Learn about the Calamity, Vengeance, and Cybernetics skill trees and which path you should take while building Amon.

Amon Skill Tree in Borderlands 4

Amon has three Action Skills to choose from, each one correlating to a skill tree.

  • Onslaught: Calamity Skill Tree
    • Activating Onslaught overloads the off-hand Forgefist for a Rocket Punch in melee. It also increases shield regeneration and applies fire damage to all weapons.
  • Scourge: Vengeance Skill Tree
    • Scourge grants Amon a shield in his off-hand to absorb frontal damage and fill up the Vengeance meter. Vengeance can be used to launch Forgewaves, which deal Cryo damage in a straight line.
  • Crucible: Cybernetics Skill Tree
    • Equipping Crucible arms Amon with two throwing axes. One deals fire damage, and the other cryo damage.

Key Skill Nodes That Define Amon’s Playstyle

Amon is complex to build as each of his skill trees stretches his playstyle in a different direction. Within the Calamity tree, the Pyroclast augment should be unlocked as soon as possible to increase his survivability and damage output, especially in solo play. At tier 4, Force of Nature is a powerful pick, causing enemies to detonate by building up a Prime with Gun Damage.

If you’re looking to max out Amon’s DPS, the Cybernetics skill tree is the way to go. The first major power jump is facilitated by the Endless War Augment. At tier 4, you can unlock Searing Cold, which freezes enemies hit with the Frost Axe. While leveling up, be sure to invest in Bolt Action for 4 seconds of Shock Damage after every reload. Past level 11, spec into Executioner increasing Critical Hit Damage by 3% per point and doubling it with Melee damage. Crucible hits count as melee damage and activate the doubling effect.
