To reliably clear the Mutated Wyvern on Very Hard in OUTERPLANE's Pursuit Operation on full auto, build a four-hero team that follows a strict speed-tuned turn order: an offensive buffer first, a defense debuffer second, a high-critical single-target striker third, and an automatic cleanser as the team anchor.

The encounter requires depleting the Wyvern's Weakness Gauge (WG) to force frequent Break states. Breaking the boss resets its attack cadence, pauses incoming damage-over-time pressure, and interrupts its enrage charging mechanics.

Required Team Roles and Stat Thresholds

Your lineup must guarantee that offensive buffs and armor shred apply before your damage carry takes a turn. If your striker acts before Defense Down is inflicted, you lose over half of your burst window and risk triggering the Wyvern's enrage timer.

Noa serves as the ideal striker because scoring critical hits triggers bonus follow-up attacks, which doubles her Weakness Gauge depletion per turn. Tio provides essential defensive coverage by automatically triggering heals and cleanses when allies receive critical or special attacks.

Auto-Battle Settings and Skill Priority

Unadjusted AI skill priorities will mismanage Chain Points and waste burst gauge resources on support abilities. Open the battle settings menu before starting the run to configure skill triggers manually:

  1. Prioritize Striker Burst Multipliers: Restrict automated Burst activation exclusively to your primary striker's Level 2 or Level 3 burst. Disable burst spending on supports so gauge points are reserved for boss Break windows.
  2. Lock Opening Skill Priorities: Set your buffer to cast their Action Gauge and critical buff ability immediately on turn one. Force your debuffer to open with their primary Defense Down skill rather than their basic attack.
  3. Configure Chain Order: Set your buffer or debuffer as the Chain starter, and place your primary striker as the Chain Finisher to capitalize on the maximum end-chain damage multiplier.

Troubleshooting Auto Wipes

  • Wiping near 50% boss health: The boss is likely outpacing your team due to failed debuffs. Check your debuffer's combat logs. If Defense Down does not consistently land, replace utility accessories with an Effectiveness necklace or an Effectiveness set to hit the 60%–70% target.
  • Collapsing from Burn damage: If your squad dies to passive damage-over-time rather than direct hits, your cleanser is moving too slowly or dying prematurely. Equip your healer with Health percentage main-stat gear and defensive talismans so they survive the Wyvern's opening strikes and cleanse burns before the boss cycles into its ultimate.
