OUTERPLANE: Sacred Guardian License Stage 10 Guide

To clear License Stage 10 Sacred Guardian in OUTERPLANE, build your team around surviving the boss's area-of-effect damage while depleting its Weakness Gauge to trigger Break windows. Instead of forcing Demiurge Ran into an Action Point-heavy carry role, deploy her as a supportive "totem" unit. This setup lets her provide steady off-turn chip damage and passive presence without draining skill resources needed by your dedicated healers and primary damage dealers.

Sacred Guardian Mechanics in Stage 10

License Stage 10 significantly scales Sacred Guardian's offensive stats compared to earlier license tiers. The boss features distinct survival checks:

Heavy Cleave Damage: The boss cycles team-wide strikes that will quickly overwhelm squishy allies if defensive mitigation is missing.
Enrage Buildup: Prolonged fights without consistent damage lead to rapid enrage scaling, resulting in team wipes.
Weakness Gauge and Break: Reducing the boss's Weakness Gauge stops incoming burst damage and induces a Break state. During Break, Sacred Guardian is incapacitated and takes amplified damage.

Your primary tactical objective is coordinating basic attacks, dual attacks, and turn order to deplete the Weakness Gauge before the boss cycles through lethal offensive rotations.

Using Demiurge Ran as a Team Totem

Deploying Demiurge Ran as a secondary anchor circumvents the resource starvation common in Stage 10. Funneling all Action Points (AP) and turns into a single fragile carry creates high wipe risk if Sacred Guardian focuses them down.

When used as a totem:

Resource Efficiency: She applies pressure, passive stats, and gauge shaving without requiring high AP consumption.
Skill Chain Generation: Her regular turns generate Chain Points to feed your team's burst rotations.
Safety Margin: Operating off low-cost actions allows your sustain units to prioritize barriers, cleanses, and heals.

Recommended Team Framework

A balanced composition for Stage 10 divides mitigation, gauge depletion, and burst execution across distinct roles:

Role	Archetype Example	Primary Responsibility
Totem Anchor	Demiurge Ran	Sustains passive presence, chips the Weakness Gauge, and deals secondary off-turn damage.
Main Sustain	Dedicated Healer (e.g., Saeran, Demiurge Astei, Tio)	Dispels debuffs, applies barriers, and stabilizes squad health above burst thresholds.
Buffer / Breaker	Speed Support	Boosts Combat Readiness, provides Attack buffs, and accelerates Skill Chain points.
Burst Striker	Single-Target DPS	Hoards AP for maximum Burst Level strikes during the vulnerable Break phase.

Battle Strategy and Break Execution

Survive the Opening Cleave: Open the fight with defensive buffs and shields. Keep all heroes above 75% health to avoid early casualties from Sacred Guardian's initial strikes.
Chip the Weakness Gauge: Use Demiurge Ran's basic attacks and dual attacks to steadily lower the boss's gauge. Conserve your primary striker's AP and avoid spending high-tier burst skills outside of Break.
Trigger the Skill Chain: As soon as the boss's Weakness Gauge empties, trigger a four-hero Skill Chain. Position your primary DPS last in the chain to deliver their highest-level Burst skill under maximum damage multipliers.
Reset and Stabilize: Reapply barriers and top off team health immediately after Break ends, as Sacred Guardian will resume its regular attack rotation.

Gearing Demiurge Ran for the Totem Role

A totem Demiurge Ran must stay alive to maintain her passive contribution. Building her as a pure glass cannon risks losing her utility to an early cleave.

Main Stats: Use Speed on boots to maintain turn pacing, Critical Hit Chance on the necklace for reliable sub-DPS, and Health or Attack on the ring depending on your healer's output.
Survivability Threshold: Ensure her total Health and Defense allow her to survive at least two unmitigated strikes without falling below 50% health.
Substats: Prioritize Speed, Health, Defense, and Critical Hit Chance over raw Attack stacking.
