The Seven Deadly Sins: Demonic Beast Surtr New Freyja Guide

To clear Demonic Beast Surtr consistently in The Seven Deadly Sins without relying on card draw RNG, run New Freyja as your primary single-target damage dealer alongside Red Freyr and Holy Relic Nanashi. This lineup counters Surtr’s wipe mechanics by providing on-demand stance removal, natural ignite protection, and passive defensive scaling from turn one.

Recommended Team Composition and Roles

This composition neutralizes Surtr’s counterattack stances while insulating your front line against stacking burn debuffs.

Unit Synergies

• New Freyja: Built-in pierce scaling and utility allow Freyja to deal heavy damage with rank-one cards, eliminating the need to waste card turns fishing for three-star merges. Her primary utility skill dispels Surtr's counter stance instantly before he can retaliate.
• Red Freyr: Grants passive protection against ignite debuffs and provides an emergency stance cancel on his Ultimate Move if Freyja’s cards are unavailable.
• Holy Relic Nanashi: Sitting in the sub-slot, Nanashi provides basic stat increases and damage reduction to Unknown allies, preventing front-line units from dropping into lethal health thresholds during multi-attack turns.

Step-by-Step Phase Strategy

Phase 1: Gauge Building and Stance Management

1. Use low-value attacks during early turns to build Ultimate Move gauges.
2. Hold at least one Freyja stance-cancel card in hand at all times.
3. Whenever Surtr assumes his defensive stance, play Freyja’s stance cancel immediately to strip damage reflection and counter retaliation.
4. Avoid moving cards manually; let passive stats accumulate naturally rather than spending turn actions solely to merge cards.

Phase 2: Debuff Control and Damage Caps

1. Maintain team health above 80 percent by cycling cleanses and healing to counteract accumulating burn damage.
2. Respect Surtr’s damage cap thresholds by distributing attacks over consecutive turns rather than dumping all burst skills into an active cap.
3. Save Freyja's highest-damage cards for the final 30 percent of the phase's health bar to bypass enrage mechanics quickly.

Phase 3: Final Burst Sequence

1. Open the final phase by deploying team buffs or debuff immunity skills.
2. Use Freyja to strip Surtr’s active stance, leaving him vulnerable to incoming attacks.
3. Launch ready Ultimate Moves to deplete the bulk of Surtr's health bar.
4. Clean up any remaining health with Freyja’s single-target skills before the boss can cycle back into high-multiplier area-of-effect abilities.

Equipment and Holy Relic Priorities

• Freyja: Equip an Attack/Critical Damage set with standard base substat rolls: Attack on top pieces, Defense on middle pieces, and HP on bottom pieces. This maximizes pierce effectiveness against Surtr's innate defense.
• Support Units: Equip Green Megellda and Nanashi with HP/Defense sets to maximize team Combat Class (CC) and ensure your team acts first.
• Holy Relics: Prioritize crafting Freyja's Holy Relic to scale her damage output in Demonic Beast content. Secure Nanashi’s Holy Relic next to activate the defensive aura for Unknown teammates.

Common Mistakes to Avoid

• Using stance cancels prematurely: Never cast Freyja’s stance-removal skill purely for chip damage when Surtr is not actively in a stance. Keep one card banked in hand to answer counter turns on demand.
• Ignoring burn stacks: Allowing burns to accumulate increases the lethal damage of Surtr’s area attacks. Rely on Freyr's passive protection or Megellda's cleanses before transitioning between phases.
• Attacking into active damage caps: Check Surtr's active buffs before executing high-damage Ultimate Moves so damage is not lost against a threshold barrier.
