Among the fractured timelines and shadows of Eterra, a legendary weapon stirs—Soulpiercer, a dagger born of void and blood. Once wielded by a fallen oracle consumed by the Umbral Cataclysm, Soulpiercer embodies lethal speed and cataclysmic burst potential. In Last Epoch, this Last Epoch gold weapon stands as a pinnacle of endgame crafting and Void-focused Rogue or Acolyte builds.

This guide covers how to acquire Soulpiercer, build synergy, Void mechanics, and tactical deployment across different content—whether you’re melting monolith bosses or shredding arena waves.

Weapon Overview: Soulpiercer

Soulpiercer is a unique dagger designed for high-speed, high-crit, Void-based burst play. It rolls with bonuses that lean into Void Damage Over Time (DoT), increased Critical Strike Chance, and conditional buffs based on enemy debuffs (like Frailty or Time Rot).

Key Stats (example roll):

+120% Increased Void Damage

+15% Critical Strike Chance

+100% Melee Void Damage Over Time

On Crit: Apply Time Rot

Unique Passive: “Edge of the Umbral Cataclysm” – Your Void crits cause an unstable collapse, dealing AoE Void damage to nearby enemies.

This dagger thrives in glass cannon builds that maximize Void DoT stacking, critical hit uptime, and fast dual-wielding synergy.

How to Obtain Soulpiercer

Soulpiercer is a unique drop from the Echo of the Umbral Oracle, a timeline-specific boss found in empowered Monoliths (Fall of the Outcasts timeline, level 90+). The drop is not target-farmable via random echoes, but can be improved via:

Blessings increasing Unique/Set item drop rate

Stability stacking for multiple Oracle fights

Using Exalted Soulfire Nodes that boost Void weapon drops

Crafting a legendary version with LP (Legendary Potential) turns Soulpiercer into a run-defining dagger—look for suffixes like Crit Multi, Melee Void Damage, or increased DoT.

Best Classes and Masteries

Rogue – Bladedancer (Primary Choice)

Bladedancer has perfect synergy with Soulpiercer:

High base crit chance

Access to Shurikens, Shadows, and Shift for repositioning

“Shadow Daggers” and “Dancing Strikes” scale off Crit and DoT

Soulpiercer turns Bladedancer into a teleporting void assassin. Shadow Daggers stack DoT and crit triggers, while your high attack speed turns Umbral Cataclysms into chain detonations.

Acolyte – Lich (Alt Choice)

Lich can dual-wield daggers and manipulate Void damage via Aura of Decay or Death Seal. With high Ward generation and scaling DoTs, Lich becomes a Void-nuking machine.

It’s a slower but tankier build, ideal for players who want to lean into apocalyptic themes and screen-clearing Void detonations.

Core Build: Bladedancer Soulpiercer

Main Skills:

Dancing Strikes – Primary DPS tool; fast multi-hit with great mobility

Shadow Cascade – Scales beautifully with multiple daggers and shadows

Shift (with Shadow buff node) – Evade and spawn clones for passive damage

Synchronized Strike – Initiates AoE burst + Shadow generation

Shurikens (Umbral Throw node) – Adds survivability and shred

Passive Synergy:

Crit Multiplier stacking (Fatal Flourish, Cloak of Shadows)

DoT Enhancements (Blood Dance, Scintillating Steel)

Shadow generation nodes to fuel Shadow Cascade

Void scaling nodes via gear, idols, and affixes

Key Buffs and Debuffs:

Stack Time Rot and Frailty with each crit

Use idols to boost Void DoT on hit

Shadow Daggers apply stacks, which detonate with Soulpiercer’s passive

Defensive Strategy

Bladedancer is inherently fragile. To survive while dual-wielding daggers:

Shift regularly to avoid telegraphed hits

Use Smoke Bomb (if included) to gain Dusk Shroud and Glancing Blow

Equip Ward on Hit or Dodge chance affixes

Stack Endurance Threshold and Crit Avoidance on gear

A single mistake can be fatal, but nimble execution allows you to play like a Void-dancing ghost, flickering in and out of danger.

Bossing with Soulpiercer

Bosses pose a unique challenge. Fortunately, Soulpiercer’s passive can burst groups, and the Time Rot debuff steadily eats away at even high-HP targets.

Boss Strategy Tips:

Open with Synchronized Strike to generate Shadows

Weave in Dancing Strikes and Shadow Cascade

Use Shift on cooldown for invulnerability and positioning

If possible, apply Time Rot early and sustain it for maximum DoT

Stay mobile—Soulpiercer is about movement, not tanking

Soulpiercer excels when bosses have adds; each add can trigger AoE Void detonations through the passive skill, allowing for chain reactions.

Arena and Monoliths

In arena waves and monolith maps, Soulpiercer unleashes pure chaos. Enemies melt in AoE bursts, and you’re rewarded for staying aggressive.

Tips for Clear Speed:

Open each fight with AoE Shadow Cascade or Synchronized Strike

Chain packs of enemies to trigger multiple Umbral Cataclysms

Maximize uptime of Shadows—each is a damage multiplier

Cycle Shurikens for defense and shred while dodging

In arena, make use of terrain and line-of-sight. Your mobility allows hit-and-run gameplay while keeping Time Rot active across enemy packs.

Recommended Gear & Idols

Gear Goals:

Increased Crit Chance / Crit Multiplier

Melee Void Damage / DoT

Void Penetration on rings or amulet

Dexterity stacking for scaling passives

Movement speed and resistances for survival

Idols to Look For:

“% Void Damage While Dual Wielding”

“Shadow Daggers Duration”

“Chance to gain Ward on Kill”

“Increased DoT damage with Dagger attacks”

Prioritize idols that synergize with Soulpiercer’s crit-based and DoT damage profile.

Crafting Tips (for Legendary Potential)

If you get a Soulpiercer with 1–2 LP, prioritize crafting:

Crit Multi (Prefix)

Melee Void Damage (Prefix)

Health, Ward Retention, or Dodge (Suffix)

Void Penetration or DoT% (Suffix)

The ideal legendary Soulpiercer maximizes burst damage while offering slight survivability through crafted suffixes.

Lore: The Umbral Cataclysm

Soulpiercer was once a ceremonial dagger used by the Oracle of Shadow, a prophet who foresaw the End of Time. In desperation, she channeled the void to avert disaster—unleashing the Umbral Cataclysm, a temporal implosion that erased her from history.

The blade now pulses with her regret. Each critical strike tears reality, echoing the moment she tore her fate apart.

Conclusion

Soulpiercer isn’t just a weapon—it’s a scalpel of the void, demanding agility, precision, and cheap Last Epoch gold aggression. In the right hands, it transforms your character into a devastating shadow dancing across timelines, carving through enemies with crit-fueled explosions and unrelenting Void decay.

Whether you’re mastering Bladedancer or warping timelines as a Lich, Soulpiercer opens the path to ruthless playstyles with endless flair. In the Edge of the Umbral Cataclysm, your foes don’t just die—they vanish.
