OUTERPLANE: How to Beat Shichifukujin's Shadow with Mero

To defeat Shichifukujin’s Shadow in OUTERPLANE's Dimensional Singularity, build the Wind striker Mero with self-sustain gear so she can finish the Earth-element boss even if the rest of your squad falls.

Because Shichifukujin's Shadow deals escalating Earth burst damage and multi-hit area attacks that frequently wipe out fragile supports, relying on traditional glass-cannon compositions often results in late-fight collapses. Mero's natural Wind elemental advantage reduces incoming damage and negates critical strike pressure, turning her into a reliable 1-on-1 finisher.

Mero Build for Dimensional Singularity

Mero requires a hybrid setup balancing defensive bulk with enough offensive power to clear the boss before enrage checks take effect. Avoid pure offensive builds, as single-target smites will quickly overwhelm her without dedicated healers.

Equipment Slot	Recommended Set / Main Stat	Preferred Substats
Armor & Weapon	Lifesteal (Gluttony) or Counter	Health %, Defense %, Attack %
Accessories	Speed or Penetration	Critical Hit Chance, Effectiveness
Necklace	Health % or Critical Damage	Speed, Defense %
Ring	Attack % or Defense %	Health %, Critical Hit Rate
Talisman	Damage Reduction or Sustain Focus	Flat Attack, Speed

A Lifesteal set provides the most reliable solo clear insurance. It ensures every skill use and basic attack restores lost health directly, eliminating Mero's reliance on allied healing cooldowns during the final stretch of the encounter.

Combat Strategy and Turn Execution

Approach the encounter with an active opening team to push early damage, but prepare to transition into a sustained solo duel if collateral damage eliminates your supports.

Open with Damage Mitigation: Apply attack down and defense debuffs during the opening cycle before Shichifukujin's Shadow unleashes its primary burst attack.
Buffer Around Ultimate Attacks: Hold Mero’s major damage skills until immediately after the boss finishes an ultimate attack phase rather than triggering damage into counter windows.
Trigger Chain Breaks: Accumulate Chain Points (CP) to execute Chain Skills during Vulnerable windows. Forcing the boss into a break state briefly pauses incoming damage and opens a safe burst window.
Transition to the 1-on-1 Duel: If wide attacks defeat your backline, continue the run. Cycle Mero's basic attacks and low-cooldown skills steadily to maintain steady health recovery through Lifesteal.

Team Composition Roles

Even though Mero can close out the battle alone, bringing functional support units speeds up the run and reduces early damage taken.

Primary Breaker or Buffer: Use an ally capable of building rapid Chain Points and applying Defense Break on turn one to maximize early damage windows.
Defensive Support: Bring a cleanser or barrier provider to manage early debuffs and blunt the boss's opening phase.
Secondary Wind Striker: Include an additional single-target Wind damage dealer to accelerate the boss through its initial health thresholds before the heaviest area attacks trigger.
