The Seven Deadly Sins: Origin Merlin Raid One-Shot Setup

To one-shot the final raid boss in The Seven Deadly Sins: Origin, players stack Clotte's ultimate damage amplification buff repeatedly during a single stagger window before unleashing Merlin's burst skill. Stacking multiple instances of Clotte's debuff pushes Merlin's critical hit beyond 10,000,000 damage, eliminating the boss immediately and bypassing phase mechanics, minion spawns, and protective barriers.

How the Clotte Buff Stacking Interaction Works

In standard encounters, Clotte applies a single-instance damage amplification debuff that refreshes its duration when recast. Under rapid energy cycling, however, her ultimate ability stacks multiplicatively without capping or removing earlier applications.

Funneling the team's energy generation and cooldown resets into Clotte allows her to apply multiple overlapping amplification debuffs while the boss is incapacitated. This exponential multiplier scales team burst damage far past normal limits.

Team Roles and Stat Priorities

Executing this burst requires specific role assignments across the four-character party:

• Merlin (Main Burst Finisher): Serves as the primary damage dealer. Equip her with maximum critical damage, elemental attack bonuses, and offensive weapon multipliers. Energy regeneration sub-stats are secondary, as Merlin only casts her burst once the setup is complete.
• Clotte (Damage Amplifier): Applies and stacks the core vulnerability debuff. Prioritize maximum energy recovery and skill haste on her equipment so she can cast her ultimate repeatedly before active debuff timers expire.
• Energy Battery Support: Provides active gauge generation and cooldown reduction to keep Clotte's ultimate cycling continuously.
• Stagger and Shred Support: Depletes the raid boss's stagger bar to immobilize the target, followed by defense-down and elemental resistance reduction skills right before Merlin attacks.

Step-by-Step Raid Boss One-Shot Rotation

Coordinate party energy and boss vulnerability using the following sequence:

1. Charge Party Meters Early: Build maximum ultimate energy on all party members during opening trash mobs or initial boss skirmishing. Do not spend Merlin's major cooldowns.
2. Break the Boss Stagger Bar: Use support skills to deplete the boss's stagger gauge, forcing a knockdown state that prevents the boss from activating shields or invulnerability phases.
3. Loop Clotte's Ultimate: Cast Clotte's ultimate immediately upon knockdown. Cycle energy battery skills to recharge Clotte and recast her ultimate repeatedly to stack the damage multiplier.
4. Apply Resistance Shreds: Trigger defense reductions and elemental resistance debuffs as Clotte finishes her stacking sequence.
5. Execute Merlin's Burst: Switch to Merlin, trigger her self-buffs, and unleash her primary ultimate attack to deal over 10,000,000 damage before the stagger window expires.

Balance and Patch Risks

Because this setup relies on an uncapped damage amplification mechanic that bypasses intended raid design, it functions as an exploit that may be adjusted in future balance patches. Avoid dismantling or ignoring standard progression gear purely to build high-haste Clotte energy sets, as an update capping her debuff to a single instance would return raid encounters to standard multi-phase rotations.
