OUTERPLANE World Boss Guide: Teams and Rotations for 4.61M Score

To reach a 4.61 million score in OUTERPLANE World Boss encounters such as Harshuna, deploy two coordinated four-hero squads that stagger your damage output across separate combat phases. Your primary squad should generate between 2.6M and 2.8M points during early break windows, leaving your secondary squad to secure the remaining 1.8M to 2.0M points against the boss's escalating enrage phases.

Success requires saving your high-multiplier skills for the boss's Grogginess state, which triggers once the Weakness Gauge (WG) fully depletes. Because the boss gains increased attack power and attack speed over time, every action must strip the Weakness Gauge, establish debuffs, or pool Action Points (AP) for break rotations.

Team 1: Fire-Element Burst Setup

Against Earth-element bosses, an offensive Fire-element core generates the highest score per turn. Team 1 relies on Valentine to cycle turn priority and critical stats, Eternal to shred enemy defenses, Astei to manage recovery and AP generation, and Aer to land maximum single-target burst damage.

Team 1 Speed Brackets and Turn Order

Maintain a 10 to 12 point Speed gap between your heroes to prevent turn order variance from disrupting your combo setup. Sequence your units in the following order:

1. Eternal (220+ Speed): Takes the opening turn to inflict 70% Defense Down and Speed Down.
2. Valentine (210–215 Speed): Acts second to cast party-wide Critical Hit Chance and Critical Damage buffs. Her basic attacks also trigger Dual Attacks to generate AP and Chain points.
3. Astei (190–200 Speed): Acts third to sustain the party, push combat readiness, or build AP.
4. Aer (160–180 Speed): Moves last among your squad with full offensive stats, ensuring all buffs and debuffs are active before she strikes.

Timing Grogginess and Chain Attacks

Avoid spending Action Points on unbuffed, low-level Bursts during standard combat phases. Conserve your AP until the boss is vulnerable to maximize scoring multipliers.

1. Control the Weakness Gauge: Stop spending optional AP when the boss's WG drops below 20%. Use standard basic attacks to chip the remaining gauge.
2. Trigger Grogginess: Break the final portion of the WG to stun the boss and initiate the vulnerability state.
3. Verify Debuffs: Check that Eternal’s 70% Defense Down has at least two turns of duration remaining on the boss before triggering your combo.
4. Execute the Chain Attack: Launch a full four-hero Chain Attack. Position Aer in the final finisher slot to maximize the accumulated Chain damage bonus.
5. Cast Burst Level 3: Immediately unleash Aer’s Skill 3 at Burst Level 3 while the boss remains broken and debuffed.

Team 2: Second Phase Strategy

When Team 1 reaches its turn limit or falls to escalating area damage, Team 2 must handle a boss with heightened offensive stats. Because Team 1 uses your premier Fire supports, Team 2 relies on alternate stat buffers and durable sustain.

• Buffers: Use Tamara to supply attack buffs, Critical Hit Chance increases, and cooldown reduction.
• Damage Dealers: Run units like Noa or Fire Rin. Noa offers consistent Weakness Gauge reduction through extra attack triggers, while Fire Rin provides burst damage if equipped with high penetration gear.
• Sustain: Bring dedicated healers like Mene or Saeran. Mene offers combat readiness management and revive utility to keep your secondary strikers alive long enough to land a four-hero Chain Attack.

Key Run Failure Points

If your score plateaus below the 4.5M threshold, evaluate these common issues:

• Low Debuffer Effectiveness: Eternal requires enough Effectiveness to bypass the boss's resistance. If Defense Down is resisted during Grogginess, the rotation loses the majority of its damage value.
• Over-Reliance on Crit Buffs: Striker builds need sufficient baseline Critical Hit Chance so they remain consistent even if buff durations lapse or get delayed.
• Uneven Squad Investment: Stacking all your best equipment on Team 1 leaves Team 2 vulnerable. If your second squad wipes immediately and scores below 1M points, a 3M-point opening run will still fail to reach the 4.61M total. Distribute gear so Team 2 can reliably contribute at least 40% of the target score.
