OUTERPLANE PvE Endgame Hero Priority and Team Guide

To clear high-tier Special Requests (Stages 11 and 12), deep Skyward Tower floors, and Guild Raids in OUTERPLANE, you must replace general campaign teams with role-specific specialists. Endgame bosses feature high defense, punishing debuffs, and enrage timers. Progression depends on three mechanical checks: pushing turn order via Action Gauge control, stripping boss defense, and depleting the Weakness Gauge to force a Break State, where enemy defense drops to zero and incoming damage multiplies.

Invest your primary resources into dedicated buffers and defense shredders first. A strong support core enables multiple elemental carries to succeed with lower individual gear requirements.

Priority Buffers and Turn Manipulators

Offensive buffers must provide Critical Hit Chance and Critical Hit Damage amplification while keeping your team ahead in turn order.

• Tamara (Water / Ranger): The highest-priority universal buffer for PvE. Her Skill 2 grants team-wide Critical Hit Chance and Critical Hit Damage buffs, while her Skill 3 applies Defense Down and knocks back enemy Action Gauges. This kit condenses three vital roles into one slot.
• Valentine (Fire / Ranger): A direct alternative to Tamara. Valentine maintains near-permanent uptime on Critical Hit buffs, pulls allies into dual attacks with her basic skill, and pushes party Action Gauges to outpace aggressive boss turns.
• Monad Eva (Light / Mage): A hybrid offensive buffer and sustain anchor. Monad Eva provides stat enhancement alongside Action Gauge acceleration. She stabilizes squads in high Skyward Tower floors and Guild Raids where burst damage threatens standard glass-cannon lineups.

Essential Debuffers and Armor Shredders

Endgame bosses possess immense base defense values that heavily reduce raw damage. Inflicting multi-turn Defense Down outside of Break windows is mandatory for beating enrage timers.

Eternal is the premier standalone armor reducer in PvE. Her ability to strip boss barriers, inflict multi-turn Defense Down, and slow boss Action Gauges prevents wipes in gear encounters such as Chimera and Masterless Guardian. For wave-based progression like Skyward Tower, Dolly neutralizes non-boss add mechanics through crowd control.

Elemental Burst Carries

Single-target burst damage dictates farming speed. Using matching elements speeds up Weakness Gauge depletion, while off-element attacks risk glancing hits that cannot critically strike.

• Aer (Fire / Striker): The primary solution for Earth bosses, particularly Chimera (the source for Speed and Critical gear sets). Her burst skills feature defense-ignoring mechanics that strip massive health thresholds during Break phases.
• Noa (Earth / Striker): The standard progression carry. Landing a critical hit triggers an automatic follow-up attack, cycling extra turns while rapidly eroding Weakness Gauges. Pairing Noa with Tamara or Valentine provides sufficient burst to clear early-to-mid endgame content.
• Ame (Earth / Striker): A dedicated single-target Earth damage dealer tailored for Water bosses and Guild Raid scoring, scaling rapidly when supported by external defense breaks.
• Demiurge Astei and Demiurge Stella (Neutral Carries): High-multiplier damage dealers used to brute-force mixed-element encounters and high-difficulty stages without suffering elemental penalties.

Healers and Defensive Anchors

Late-game sustain relies on proactive debuff removal, turn cycling, and revival rather than raw heal numbers.

• Tio (Fire / Healer): The top reactive cleanser in PvE despite being a base 3-star hero. Her passive automatically cleanses debuffs and triggers team healing whenever an ally receives a negative status effect, completely neutralizing bosses that inflict bleed, burn, or poison.
• Mene (Water / Healer): A safety net for high-tier Special Requests. Mene provides continuous regeneration, team-wide Action Gauge pushes, and a full-team revive to recover runs disrupted by bad damage variance.
• Saeran (Wind / Healer): A cooldown reduction specialist. Saeran resets skill cooldowns on your primary damage dealer and sustains the team, allowing carries like Aer or Ame to execute back-to-back burst rotations during Break windows.

Recommended Farming Compositions

Set up your initial farming teams to match the specific mechanics of each dungeon:

Chimera (Speed and Critical Gear)

• Team: Aer, Valentine, Eternal, Tio
• Execution: Tio cleanses burn stacks automatically. Eternal removes boss barriers and lands Defense Down. Valentine keeps Critical Hit buffs active, allowing Aer to break the boss and trigger defense-ignoring burst damage.

Glicys (Counter and Lifesteal Gear)

• Team: Noa, Tamara, Saeran, Ame
• Execution: Exploit Earth elemental advantage to reduce the Weakness Gauge. Tamara establishes Critical buffs and Action Gauge pushback, while Saeran resets Ame and Noa to chain burst rotations.

Skyward Tower Floor Climbs

• Team: Monad Eva, Dolly, Noa, Tamara
• Execution: Dolly locks down dangerous mob waves with Blind and Silence. Tamara and Monad Eva accelerate team turns, allowing Noa to wipe waves before enemies can cycle their skills.
