Monster Super League: Belial Ultimate Evolution Guide

To unlock Belial’s Ultimate Evolution in Monster Super League, you must raise your base Belial to Evolution 3, ascend it to 6 stars at level 60, and gather the required character insignias alongside elemental materials and gold. Completing the evolution enhances base stats, scales skill damage multipliers, and unlocks upgraded ultimate skill effects.

Base Prerequisites and Materials

The evolution interface blocks any unit that has not met full base progression. You cannot trigger the upgrade on an Evolution 1 or Evolution 2 Belial.

Requirement	Target Milestone	Primary Acquisition Method
Base Form	Evolution 3, 6-Star, Level 60	Standard evolution fodder or Holy Gleems, followed by Starstone Ascension
Catalyst	Belial Insignias	Event exchanges, shop packages, or special missions
Elemental Stones	High Elemental Stones	Daily Starstone Dungeons matching your Belial's element
Currency	Gold Reserves	Golem Dungeon farming (floors B10 and B11) and selling extra gems

Reaching Evolution 3 requires either duplicate Belials or Holy Gleems. Using Holy Gleems on natural 5-star units preserves duplicate summons for subsequent evolution stages. Once your Belial reaches level 60 at 6 stars, open your Astromon storage menu to access the Ultimate Evolution portal, where you can view the exact insignia count and gold cost for your specific variant.

Combat Benefits of the Ultimate Form

Advancing Belial to Ultimate Evolution provides three direct performance upgrades across combat modes:

Base Stat Scaling: Increases health, attack, and defense pools to improve survivability against burst damage in PvP and high-tier dungeons.
Higher Skill Multipliers: Raises the damage output on active abilities, allowing hybrid and support variants to deal meaningful secondary damage.
Skill Reliability: Boosts debuff stability and status proc consistency depending on the specific element being fielded.

Light and Dark Belials gain the durability needed to sustain multiple rounds in Astromon League offense and defense lineups. Elemental variants (Fire, Water, and Wood) translate their upgraded attack and skill potency into faster wave clears and higher contribution scores in Clan Battles.

Post-Evolution Gem and Trinket Configuration

Higher natural defensive stats allow you to adapt your gem sets based on Belial's role rather than stacking pure survivability.

Gem Sets by Role

Attacker Builds (Dark, Fire): Target a 100% Critical Rate threshold. Equip an Intuition Set (Critical Rate +20%) or a Ruin Set (Critical Damage +40%) with a Critical Rate primary gem on a square slot.
Disruptor and Defense Builds (Light, Water, Wood): Equip a Protection Set (Defense +20%) or Conviction Set (Resist +20%). Prioritize HP%, Defense%, and Effect Resistance% primary gems to prevent enemy crowd-control lockouts in Astromon League.

Trinket Priorities

Equip refined 5-star and 6-star trinkets to scale the percentage bonuses granted by Ultimate Evolution. Prioritize Critical Resistance and Effect Resistance substats on defensive trinkets to keep your Belial operational before using its ultimate skill.
