OUTERPLANE Dimensional Singularity Belial Boss Guide

To clear Abomination Hunter Belial in OUTERPLANE’s Dimensional Singularity, build your team around buff removal and sustained survival rather than raw burst damage. Belial stacks aggressive stat enhancements and defensive barriers that turn his area-of-effect attacks lethal. Bringing a dedicated dispel specialist like Fortuna allows you to strip these enhancements before he unleashes major attacks, creating reliable openings to break and eliminate him.

Team Composition and Core Roles

A successful team must cover four distinct duties: consistent buff removal, single-target burst damage, defense reduction, and party sustain.

Role	Recommended Heroes	Primary Encounter Duty
Dispel Utility	Fortuna	Removes Belial's stat buffs and protective barriers
Primary DPS	Fire Single-Target Carry	Depletes boss health during Break windows and finishes Chain Attacks
Buffer / Defense Breaker	Valentine, Tamara, Eternal	Inflicts Defense Down, increases party critical stats, and builds Chain Points
Sustained Healer	Mene, Tio, Demiurge Astei	Cleanses party debuffs, restores party health, and prevents wipe conditions

Fortuna serves as the primary utility counter in this rotation because her Fire typing avoids elemental penalties, and her skill rotation strips buffs quickly enough to match Belial's enhancement cycles. Running two damage dealers at the expense of healing or dispel utility often causes team wipes, as Belial's baseline attacks easily overwhelm unprotected squads.

Skill Timing and Turn Sequence

Managing Belial requires holding your dispel skills for his activation windows rather than using them automatically.

Initial Setup: Buff party critical stats and attack power on turn one. Land Defense Down on Belial, but do not cast Fortuna’s buff removal until Belial deploys his first barrier or offensive steroid.
Buff Removal: Activate Fortuna’s dispel skill immediately after Belial casts his enhancements. Stripping his attack buffs before his follow-up cleave shields fragile backline heroes from lethal spikes.
Trigger the Break State: After stripping his defensive shields, use high-action-gauge skills to deplete Belial’s Break gauge.
Chain Attack Execution: Once Belial enters the Break state, execute a four-hero Chain Attack. Route your accumulated Chain Points into your Fire carry's Finisher to deal the bulk of your encounter damage.
Phase Reset: Belial gains turn meter after recovering from a Break state and promptly recasts enhancements. Restore your team’s health, reapply Defense Down, and hold Fortuna's turn to counter his next buff cycle.

Stat Tuning and Gear Priorities

To execute this strategy smoothly, tune the stats of your key units:

Fortuna: Prioritize Speed and Effectiveness. Fortuna must act after Belial buffs himself but before his primary damage turn executes. High Effectiveness ensures her dispel bypasses Belial’s effect resistance. Equip Health or Defense on accessories so she survives stray area damage.
Primary DPS: Balance Speed with Critical Damage and Attack. If your carry is too slow, Belial will exit his Break state and refresh his barriers before your team completes its damage cycle.
Healer and Support: Equip sufficient Speed and survivability to ensure heals and cleanses cycle ahead of incoming boss cleaves.
