Last Epoch Falconer Guide – Billion DPS Umbra Blade Build ~ HaploGamingChef

Overview of the Build

This guide covers a high-performance Falconer build in Last Epoch designed for bossing with extreme efficiency. By combining traps, Umbra Blades, and high cooldown recovery, this setup reaches billions in DPS potential. Focused on single-target destruction, this Falconer configuration is ideal for farming Uber bosses, especially Uber Abberoth, with unmatched speed and power.

You'll learn what makes this build so effective, including gearing strategies, skill tree setups, and how to maintain mana and survivability. While it's not ideal for mapping, it's arguably one of the strongest options for focused boss content in the current patch.

Understanding the Core Concept Behind This Falconer Build

At the heart of this Falconer build is a return to traps and cooldown-focused play. Unlike previous dual-wielding or passive scaling builds, this version capitalizes on consistent trap deployment and the powerful Umbra Blade mechanic. The synergy between Aerial Assault, Dive Bomb, and Explosive Traps allows for rapid application of damage-dealing elements that ramp over time. As cooldowns decrease, your ability to drop more traps and unleash more blades increases, creating a compounding DPS loop that escalates in just seconds.

The main mechanic revolves around Midnight Aviary, a crucial unique that dramatically boosts the number of Umbra Blades generated. With every Aerial Assault, more blades spawn and stack on the battlefield, leading to exponential damage scaling. While this takes a few seconds to ramp up during combat, the end result is billions of damage per second—far surpassing more commonly played variants like dual-wield or auto-cast setups.

Gear Overview – What You Need and What You Can Skip

One of the strengths of this setup is that it doesn't demand highly optimized or ultra-rare gear to be effective. The showcased build uses low LP (Legendary Potential) gear with modest affixes. Core priorities include HP, Cooldown Recovery Speed, Critical Strike Chance, and Dexterity—but you don’t need perfect rolls. In fact, the original run featured idols with only HP stats and zero added damage. This highlights the build’s raw power even with accessible gear.

Key items include Peak of the Mountain (with any LP) for dexterity scaling, Blood Roost for tankiness, and Null Portent for elemental resistance and survivability. Many of these pieces are reasonably obtainable for mid-to-late game players, especially in online trade environments. If you're playing solo, focus on tier 7 cooldown and dexterity rolls, and you'll be close to optimal.

Skill Setup – Maximize Traps, Blades, and Burst

This build focuses on skill synergy to keep Umbra Blades flowing while stacking buffs and triggering traps. Your core active skills include:

Explosive Trap – Key to triggering buffs and passive effects. The explosions help apply debuffs and boost Umbra Blade damage.
Aerial Assault – Functions as your main mobility and damage-deploying ability. Every use drops Umbra Blades due to Midnight Aviary, making it a core source of scaling.
Dive Bomb – High-impact finisher that synergizes with trap effects and gets heavily boosted by cooldown recovery.
Umbral Blades – Used passively via triggers. No need to cast this directly thanks to item effects and skill node interactions.
Smoke Bomb or Decoy – Use one defensive utility skill to help with survivability and mana control.

In your skill trees, invest heavily into nodes that lower cooldowns, boost trap effectiveness, and extend Umbra Blade duration. The more frequently you can cast Aerial Assault, the faster your Umbra Blades stack and your damage ramps.

Cooldown Optimization and Mana Sustain

Cooldown recovery is the engine that drives this build’s exponential damage. By focusing on Cooldown Recovery Speed affixes and relevant skill nodes, you significantly reduce downtime between Aerial Assaults and Dive Bombs. This translates to more frequent Umbra Blade drops and trap activations. Look for tier 7 cooldown recovery on gear, and aim to stack as much as possible through both gear and passive trees. The faster you loop your core skills, the faster your damage snowballs.

However, this high activity level comes at a cost: mana sustain. Without proper management, you'll run out of mana quickly, especially outside boss fights. The key fix lies in the Dive Bomb skill tree—specifically, a node that restores mana on use. This keeps you functional during extended boss engagements. For general mapping or trash clearing, mana will be a consistent issue, which is why this build isn’t recommended for mapping content. It's built purely for high DPS boss farming, and it performs that role exceptionally well.

Boss Fight Performance – Why This Build Excels at Single-Target Damage

This Falconer setup is engineered specifically for Uber boss farming. It’s built to ramp quickly, sustain under pressure, and apply consistent, escalating damage. Against bosses like Uber Abberoth, the trap-triggered buffs and Umbra Blade stacking show their true strength. While the build may seem underwhelming in the first few seconds, once your skills begin to loop and buffs are in place, damage numbers skyrocket. With proper positioning and timing, you’ll routinely see hundreds of millions to billions in DPS output.

Optimal bossing requires stacking Explosive Traps early to build buffs and create synergy with Umbra Blade triggers. Positioning is important—you want bosses near traps and other targets to maximize AoE overlap. In ideal conditions, bosses can go down in seconds. This is further enhanced by the build's natural toughness, as it incorporates defensive items like Blood Roost and Null Portent, allowing you to stay in close proximity during high-stakes engagements without being one-shot.

Limitations – Why This Isn’t a Mapping Build

While this Falconer setup excels at single-target bossing, it’s noticeably weaker in mapping scenarios. The core issue lies in the investment required for Midnight Aviary and trap synergy, which consumes so many passive and skill points that there's no room for key movement or AoE-clear options like Rushing Wings. This results in clunky, slow mapping with poor mana sustain and inconsistent trash clearing performance.

Furthermore, using traps and falcon abilities simultaneously creates high mana strain outside of boss fights. This becomes frustrating in echo runs or monolith farming, where sustained movement and frequent casting are critical. Unless your gear is exceptionally optimized for mana regen and cooldown efficiency, expect to run out of resources often. Because of this, it's not recommended to use this build for general progression or content grinding. Instead, keep it as a specialized loadout for farming bosses once you’ve already completed other content.

When and How to Transition Into This Build

This setup shines when used strategically—not as a general-purpose build. The best time to switch is when you've stockpiled Uber boss echoes, especially Uber Abberoth, and you’re ready to farm them in sequence. If you’ve cleared normal Abberoth enough times and accumulated dozens or hundreds of high-value echoes, then it’s worth doing a respec to optimize your Falconer for this specific purpose.

To transition effectively:

Make sure you have basic cooldown and HP gear, even if it’s only 1–2 LP with tier 7 affixes.
Focus on crafting or trading for Blood Roost, Null Portent, and Midnight Aviary.
Consider building a new Falconer from scratch if your current one is spec’d for mapping, since a full respec is often more time-efficient than trying to retrofit your current build.

Once you’re ready, fill your echo web with boss runs, swap gear and passive points, and dive into boss farming. You’ll get better returns on time spent than most other builds when used this way.

Is This Build Overpowered? Likely Nerfs Ahead

There’s growing consensus that this Falconer trap build is unbalanced in its current form. The sheer volume of Umbra Blades, made possible by Midnight Aviary and near-instant cooldown loops, allows it to achieve damage output that far exceeds typical expectations—even rivaling or surpassing builds previously capped at 300 million DPS. With proper setup, this configuration ramps into billions of damage, creating a DPS ceiling that appears unintended by design.

What makes the build especially dangerous in terms of balance is the interaction between Umbra Blade duration, Dexterity scaling via unique boots, and cooldown modifiers. You can spawn dozens of Umbra Blades simultaneously, while maintaining nearly continuous Dive Bomb uptime. While nothing appears technically bugged, many players expect cooldown or Umbra Blade stacking nodes to be capped in a future patch—likely limiting the number of simultaneous buffs or blade spawns.

Final Thoughts – Who Should Use This Build and When

This Falconer setup is best suited for experienced players who have access to mid-to-high tier gear and are looking to specialize in boss farming. It’s not a build for general play or beginners, due to its gear dependency and mana management challenges. However, in the right context—particularly mass farming Uber bosses—it offers an unmatched balance of tankiness and extreme burst DPS.

Use this build only when:

You have the required uniques and cooldown gear.
You’ve planned a boss farming session with multiple stored echoes.
You’re fine sacrificing mapping speed for pure boss efficiency.

With that in mind, this build is likely to be adjusted or nerfed in future patches due to its extreme scaling. Use it now while it’s viable, but don’t rely on it as a permanent meta solution.

Conclusion

The Falconer Trap Build with Umbra Blades in Last Epoch is currently one of the strongest bossing setups available. With minimal investment, it delivers unmatched DPS output through effective trap scaling, cooldown stacking, and Umbra Blade synergy. While the build isn't suitable for general gameplay like mapping, it thrives in targeted boss runs, especially Uber Abberoth farming.

Players considering this build should be prepared for a specialized playstyle and have access to key uniques and gear. With its unmatched burst potential and robust defenses, this is a go-to option for late-game farming—just be aware that balance changes may hit this setup soon.
