Seven Deadly Sins: Origin Ferzen Mines Raid & Longdead Guide

To survive the final Longdead boss in the Seven Deadly Sins: Origin Ferzen Mines Raid, you must interrupt its instant-death wipe attack using the arena environment. Lure Longdead near the powder kegs placed around the boss room, then detonate a keg right as the boss begins its wipe sequence to cancel the one-hit kill.

Longdead One-Hit Kill Strategy

The Longdead fight centers on managing its wipe mechanic rather than relying solely on raw stats.

Positioning: Kiting the boss near active powder kegs at all times prevents rushing across the arena when the wipe begins.
Trigger Timing: Watch for the boss's wipe sequence signal. Trigger the adjacent powder keg immediately upon seeing the startup animation.
Execution Signal: The explosion interrupts the channel and bypasses the wipe entirely. Triggering a keg too early leaves you without an active keg when the actual wipe occurs.

Selecting Ferzen Mines Pledges

Pledges modify raid conditions and can easily invalidate your run if chosen poorly.

Avoid Damage Penalties: Do not select Pledges that directly reduce your overall damage output or main attack abilities. The raid has high DPS requirements, and lowering your damage output leads to timed failures.
Select Operational Handicaps: Choose debuffs that impact non-essential mechanics or impose minor tactical constraints rather than structural damage cuts.

Earth Team Survival and Workarounds

The popular Earth team composition—Earth Ban, Khala, and Elaine—faces severe survivability issues in Ferzen Mines.

The Problem: The raid deals heavy, continuous incoming damage. The Earth Ban/Khala/Elaine core lacks the sustained healing necessary to keep team health at safe thresholds throughout extended fights.
The Solution: If running an Earth team, integrate active shielding items or off-spec healing options to offset the missing passive sustain. Alternatively, swap out a secondary unit for a dedicated support or healer to maintain your health bar.

Abyssal Predator Armor Set Requirements

The Abyssal Predator set is a specialized gear choice that does not suit every character.

Gear Consideration	Recommendation	Condition
Primary DPS Utility	Build for specific DPS units like Gowther	Depends heavily on your main DPS setup
General Roster Use	Avoid equipping on general support/flex slots	Standard gear sets generally outperform it
Earring Roll Check	Mandatory optimal Earring stat roll	Do not equip without the specific Earring roll

Without hitting the required Earring stat roll, the Abyssal Predator set loses much of its performance value and should be held in inventory until the correct stats are secured.
