Make Amon Unstoppable: 3 Must-Try Borderlands 4 Builds — Explosive, Melee & Drone Setups

Amon, the Forgeknight in Borderlands 4, plays like a heavy-hitting frontline who also gets benefits from putting himself in danger. Below you’ll find four compact breakdowns: an overview of his skill trees and three community-tested builds that show different ways to use his kit.

1. Amon’s skill tree and playstyle, explained
2. Blastoid Amon build
3. Onslaughter Amon build
4. Minion Amon build

Amon’s skill tree and playstyle, explained

Amon’s kit mixes defensive and offensive tools. In short: each major skill tree focuses on a different role.

Blue tree: grants a shield that absorbs damage and converts that absorbed damage into a damage buff for Amon’s attacks. This tree leans more defensive while building offensive upside.

Red tree: unlocks the Onslaughter Action skill, which increases movement speed, adds fire damage to gun attacks, and provides a shield while active. It also supports melee-heavy play and synergies with passives that buff on-forge usage.

Green tree: is more offensive and centered on ranged, thrown forgeaxes that deal elemental damage. Several green passives spawn autonomous weapons or drones that attack at range.

Community creators have pushed specific Amon builds around these trees. For example, EpicNNG explored a blue-tree explosive build, ItalianSpartacus worked on a green-tree drone/minion build, and MrTx01 focused on a red-tree melee Onslaughter setup.

Blastoid Amon build

The Blastoid is a blue-tree build designed to make Amon blow things up from a distance using ordnance interactions. Key factual components:

• Core ordnance: the heavy weapon “Unobtainable Hailspike,” which has the Two-Shot affix (fires two projectiles) and the MIRV affix (spawns explosive orbs when projectiles explode).
• Ammo/firmware interaction: running three pieces with the High Caliber firmware makes your projectiles pierce targets. When combined with MIRV, piercing causes projectiles to explode in multiple places (on hit and on the surfaces they hit), increasing orb spawns.
• Result: the interaction can spawn many explosive orbs per shot — the build’s documented case reaches up to 16 hits per shot on a single aim line due to mirroring of projectiles and orb spawns.
• Recommended gear: an Amp-affix shield to scale the damage buff, plus the legendary repkit “Shiny War Paint” as described by the original creator for best results.

For the complete walkthrough and exact gear/skill choices, watch EpicNNG’s video linked below.

Onslaughter Amon build

The Onslaughter build centers on melee bursts and stacking effects. Here are the concrete facts about how it works.

• Core passive: Berserk — grants bonus cryo damage with gun and melee attacks and removes slow while active; the passive is activated via Amon’s forge skill.
• Action skill: use Onslaughter while Berserk is active to get movement and damage buffs and to chain kills into more damage.
• Scaling mechanic: the There Is Only Red skill increases bonus cryo damage and refreshes Berserk duration for each kill while Berserk is active, making kill chains sustain the effect.
• Augment choices: creators recommend switching augments by activity: Pyroclast or Fellfrost for mobbing, and Force of Nature for bosses. With Force of Nature, gun damage applied during Onslaughter builds stacks that can be detonated for large single-target hits via Rocket Punch or forge attacks.

MrTx01 details skill points, augments and gear in his guide; watch the video for the full setup and demonstrations.

Minion Amon build

The Minion build converts Amon into a pseudo-summoner using green-tree passives that spawn autonomous weapons. Facts to know:

• Key skills: Tempered Pyre, Twin Tempers, Tempered Lightning, and Tempered Ice. Each spawns a different drone-type (two axes, one hammer, a sword, etc.) that deals a specific elemental damage type.
• Play pattern: drones are the primary damage source; using Action skill and ordnance tends to spawn or refresh drones, while passives like Masterwork and Escalation increase drone DPS and uptime.
• Gear notes: the build is less gear-dependent than some other Amon setups, but a corrosive weapon is recommended to handle armored enemies effectively.

ItalianSpartacus walks through point-by-point choices and shows the drones in action in his video.

If you’re new to Kairos or looking for broader help, check Borderlands 4 beginner resources and class guides before investing heavily in one build. Also, remember to prioritize SDU tokens, vehicles, and fast travel points when exploring the map; these are practical, factual QoL steps that support any build you choose.
