Amon the Forgeknight is a frontline juggernaut in Borderlands 4. His three skill trees — Cybernetics (Crucible), Calamity (Onslaught), and Vengeance (Scourge) — let him scale from an explosive mob clearer into a nearly unkillable endgame boss shredder. This guide covers builds, skill orders, weapons, gear, and leveling 1–50, with all details verified against official skill trees and top build guides.
1. Amon Build Overview (Skills & Playstyle)
Amon the Forgeknight excels as a versatile frontliner. His trees let him pivot roles while leveling: a Cybernetics axe-throwing mob clearer, a Calamity shield tank, and a Vengeance Cryo boss killer. With the right point allocation, Amon combines AoE chain detonations, shield sustain, and endgame Cryo control, making him a top-tier pick for both solo and co-op play.
2. Amon Skill Trees Explained
2.1 Cybernetics (Best Fire/Frost Axe Build) — Action Skill: Crucible
The Cybernetics tree centers on throwing elemental Forgeaxes and summoning Forgedrones. With Tempered Pyre and Twin Tempers, you unlock Fire and Cryo Forgedrones for dual support. Executioner and Bellows amplify your critical damage and gun DPS during Forgeskill windows. This is the best tree from level 1–20, offering unmatched mob-clearing efficiency.
2.2 Calamity (Best Tank Build) — Action Skill: Onslaught
The Calamity tree transforms Amon into a shield-regenerating melee tank. Impetus, Gut Punch, and Heavy Plate keep you alive, while Metal Urge ensures nearly permanent uptime on Onslaught. This path shines from levels 20–35 in co-op, where Amon becomes the frontline anchor while allies deal ranged DPS.
2.3 Vengeance (Best Cryo Boss Build) — Action Skill: Scourge
The Vengeance tree is Amon’s late-game boss-killer path. Age of Ice, Tail of the Comet, and Machinist sustain your ammo and ordnance, while Icy Rage and Glacial Rapture let you freeze bosses solid and shred them with Cryo burst. From levels 35–50, this tree makes Amon one of the strongest endgame Vault Hunters.

3. Best Augments & Capstones for Amon
- Conflangarang (Cybernetics/Calamity) – Converts melee swings into spinning fire trails with burn DoT.
- Hoarcleave / Stormcutter (Calamity options) – Cryo or Shock melee finishers for alternate playstyles.
- Glacial Rapture (Vengeance capstone) – Upgrades Firewall into Cryo fissures that freeze groups and bosses (+30–50% bonus damage).
- Wrathfall (Vengeance alt) – High-risk Cryo burst for advanced boss setups.
4. Amon Leveling Guide (1–50)
Amon’s cleanest route is Cybernetics 1–20 for explosive clears, Calamity 20–35 for shielded brawling and team utility, then Vengeance 35–50 to freeze and shred bosses. Skill caps and names below are verified against official trees. Augments/capstones don’t cost points; passives do.
4.1 Amon Leveling Build 1–20 (Cybernetics Starter)
Goal: stack crit and Forgeskill damage, bring in the Forgedrones, and multiply gun damage with Bellows. This is the most reliable low-gear opener.
- Executioner (5/5) – Big critical hit damage, doubled briefly after any melee hit.
- Cast Iron (3/5) – Faster Forgeskill cooldown and better gun handling.
- Tempered Pyre (2/5) – Spawns a Fire Forgedrone on Forgeskill use.
- Twin Tempers (1/1) – Adds a Cryo Forgedrone alongside the Fire drone.
- Vital Organs (5/5) – Kill Skill: boosts gun crit chance after each kill.
- Bellows (5/5) – After Forgeskill, gain a gun damage buff for a duration.
Total: 21 points in Cybernetics. Dual drones + crit scaling make mob clears trivial.
4.2 Amon Leveling Build 20–35 (Calamity Tank)
Respec into Calamity at 20. You’ll sprint into fights, heal/shield constantly, and control crowds with Rocket Punch. Prioritize uptime (Metal Urge) and sustain (Heavy Plate), then add melee/status scaling.
- Impetus (3/3) – Kill Skill: restores shields + movement speed.
- Gut Punch (3/3) – Applies Weakness, debuffing enemies for team DPS.
- Tritanium Knuckles (5/5) – Boosts melee & Rocket Punch damage.
- Metal Urge (5/5) – Gunfire reduces Onslaught cooldown.
- Wield the Storm (5/5) – Increases status effect damage and duration.
- Forged in Steel (1/1) – Invulnerability window on Forgeskill use.
- Heavy Plate (5/5) – Expands shield capacity & overshields.
Total: 35 points in Calamity. Optional extras after 35: Bloodlust (5/5), Brimming Vigor (5/5), or Rimebreak (3/3) for sustain.
4.3 Amon Leveling Build 35–50 (Vengeance Cryo Boss Killer)
At level 35, respec into Vengeance. Firewall blocks projectiles while boosting your damage as you fire through it. Cryo synergy from Age of Ice, Tail of the Comet, and Machinist sustain ammo and ordnance, while Glacial Rapture adds devastating boss control.
- Age of Ice (5/5) – Kill Skill: Cryo kills stack bonus gun damage.
- Tail of the Comet (3/3) – Ordnance hits apply Cryo status.
- Machinist (3/3) – Kill Skill: restores ordnance cooldown.
- Scorched Kairos (5/5) – Increases ordnance damage + heavy mag size.
- Ancient Ways (5/5) – Flat Cryo damage bonus.
- Icy Rage (5/5) – Extra damage vs frozen targets.
- Glacial Rapture (1/1) – Capstone: Firewall evolves into Cryo fissures.
Total by 50: Full Vengeance Cryo core. For safety, flex spare points into Heavy Plate or Brimming Vigor after essentials.
5. Best Weapons for Amon in Borderlands 4
Amon’s weapon loadout should always align with his current skill tree. Matching element and damage type ensures you maximize Forgeskill buffs, status effects, and Cryo synergies. These are the best weapons for each stage:
- Cybernetics (1–20): Incendiary SMGs and Shotguns. Fast-firing weapons take full advantage of Bellows gun damage buffs and Forgedrone priming.
- Calamity (20–35): The Rainbow Vomit Shotgun (Legendary Jakobs elemental) paired with Incendiary ARs provides consistent DPS while tanking.
- Vengeance (35–50): Rainbow Vomit Shotgun + Torgue Multi-M Missile Launcher deliver the best Cryo boss synergy, combining ordnance scaling with freeze uptime.
- Rainbow Vomit Shotgun
- Darkbeast – SMGs
6. Best Gear for Amon (Shields, Repkits, Mods & Firmware)
Beyond weapons, Amon’s performance relies on the right shields, Repkits, class mods, and firmware. These items allow him to fully tank arenas in Calamity and freeze-lock bosses in Vengeance.
- Shield: Firewerks Shield – Legendary tank shield dropped by Splashzone. Fires missiles when segments break, making it Amon’s best defensive option.
- Repkits: Use Healing Repkits in the early game for sustain, then swap to Offensive Repkits in endgame to maximize Cryo DPS.
- Class Mod: Chilling Elementalist – Dropped by Inceptus in Fadefields Vault. Increases Cryo damage and heavily boosts Vengeance builds.
- Firmware: Baker (shield/health sustain) + GOOFJFC (Action Skill uptime). This combination gives the best mix of survivability and Scourge uptime.
7. Best Solo vs Co-op Builds for Amon
Amon adapts depending on whether you’re playing solo or in a group. Solo players should prioritize consistent damage and sustain, while co-op players can fully lean into tanking for allies.
- Solo: Cybernetics early for safe mob clears, then respec into Vengeance at 35 for Cryo boss farming and sustain.
- Co-op: Calamity is the best tank path. Amon holds aggro, regenerates shields, and debuffs enemies with Gut Punch, letting allies unload ranged DPS safely.
8. Best Amon Endgame Specializations & Firmware
At max level, Amon unlocks specializations and firmware chips for further build refinement. These choices depend on whether you’re speedrunning, farming bosses, or raiding in co-op.
- Runner (10 pts): Unlocks Bullet Train hipfire for speedrunning and fast clears.
- Brute (20 pts): +30% damage dealt and damage reduction; the best all-rounder choice for both solo and co-op endgame.
- Survivor: Focuses on regeneration and sustain; ideal for raid-level encounters where tanking is required.
- Firmware Combo: Baker + GOOFJFC is the recommended late-game pairing for survivability and Scourge uptime.
9. How to Play Amon Effectively (Combat Tips & Tricks)
Each tree plays differently. Mastering Amon means adjusting your playstyle as you respec through Cybernetics, Calamity, and Vengeance.
- Cybernetics: Throw Flame Axes for chain detonations, prime packs, and let Forgedrones finish stragglers. Always refresh Bellows with Forgeskills before gun bursts.
- Calamity: Lead fights. Use Impetus for shield sustain, apply Gut Punch debuffs, and control groups with Rocket Punch knockback.
- Vengeance: Always keep Firewall active, fire Cryo ordnance through it, and freeze bosses with Age of Ice and Tail of the Comet. Chain Glacial Rapture to maintain freeze-locks in endgame fights.
10. How to Beat Bosses with Amon Builds
Amon is one of the strongest boss killers in Borderlands 4 once you respec into the Vengeance tree. Proper use of Firewall and Cryo synergy lets you survive heavy phases and shred even raid bosses.
- Use Firewall: Deploy Firewall to block incoming projectiles and create a safe firing lane during high-damage boss phases.
- Freeze for Bonus Damage: Cryo synergy grants +30–50% bonus gun damage to frozen targets. Age of Ice and Tail of the Comet keep bosses frozen.
- Glacial Rapture: Capstone upgrade that erupts Firewall into Cryo fissures. Use it to wipe adds and lock bosses in place.
- Sustain with Machinist: Restores ordnance cooldown, letting you fire rockets and grenades nonstop during long encounters.
11. Best Co-op Team Synergies for Amon
Amon’s role as a shielded frontliner pairs well with every other Vault Hunter. His crowd control and survivability amplify teammates’ DPS and survivability.
- Amon + Vex: Vex’s minion swarms overwhelm enemies while Amon anchors the frontline with Firewall and Onslaught shield regen.
- Amon + Harlowe: Harlowe’s gravity manipulation combined with Amon’s Cryo fissures creates devastating battlefield control.
- Amon + Rafa: Two bruisers together make for aggressive co-op runs, ideal for farming and raid pushes.
- Vex
- Harlow
- Rafa
12. Common Amon Build Mistakes to Avoid
Many players underperform with Amon by misallocating skill points or delaying respeccing. Avoid these mistakes to keep him at peak strength:
- Not respeccing at 20 and 35: Staying in Cybernetics too long weakens your mid-game. Always swap to Calamity at 20 and Vengeance at 35.
- Trying to snipe: Amon isn’t built for long-range play. Focus on melee, shields, and Cryo synergy instead of precision rifles.
- Neglecting Repkits and shields: Without gear like the Firewerks Shield and Offensive Repkits, Amon struggles in late-game raids.

15. Which Amon Build Should You Choose?
Your choice depends on progression:
- 1–20 (Cybernetics): Dual Forgedrones + Bellows gun buffs for safe leveling.
- 20–35 (Calamity): Tank role; shield sustain + crowd control make it best for co-op.
- 35–50 (Vengeance): Boss killer; Cryo synergy + Firewall make it top endgame choice.
Final Recommendation: Follow the Cybernetics → Calamity → Vengeance respec path. This guarantees the smoothest 1–50 progression and the strongest endgame Amon build in Borderlands 4.
