Eternal Shinobi: Shadow Saga 7-Star Promotion Guide

To promote a ninja from 6 stars to 7 stars in Eternal Shinobi: Shadow Saga, you must first raise the target hero to their maximum 6-star level cap. Once the level cap is met, the promotion screen requires fusing specific duplicate shards, same-element fodder units, breakthrough stones, and gold.

Prioritize upgrading your primary damage carry first, and avoid spending duplicate materials or premium conversion shards on support units until your main attacker reaches 7 stars.

7-Star Breakthrough Requirements

The star breakthrough interface will remain locked until your 6-star ninja hits the maximum level ceiling. Once the hero is eligible, star ascension consumes four core resources:

• Identical Hero Copies: At least one designated 5-star or 6-star duplicate copy or shard set of the base unit.
• Element-Matched Fodder: Additional 5-star or 6-star ninjas belonging to the same element or faction to serve as fusion material.
• Breakthrough Stones: A fixed quantity of high-grade promotion stones obtained through daily trials and shop redemptions.
• Gold: A standard fusion fee that scales with the hero's base rarity tier.

Because exact hero duplicates represent the main bottleneck for 7-star breakthroughs, save universal conversion shards exclusively for rare, premium-faction units rather than spending them on common summon-pool characters.

Promotion Resource Sourcing

Distributing materials across multiple heroes simultaneously will stall your account progression. Focus your daily income into one designated unit at a time.

Roster Promotion Priority

Promoting your primary damage dealer yields immediate returns across both PvE campaign stages and PvP modes. Attackers receive substantial offensive stat scaling and passive enhancements upon reaching 7 stars, directly reducing fight duration.

Follow this upgrade sequence across your lineup:

1. Primary Carry: Upgrading your main damage dealer breaks campaign progression walls, which increases your passive hourly resource generation.
2. Frontline Tank: Tanks gain critical HP multipliers and damage mitigation at 7 stars, preventing them from falling before activating defensive abilities.
3. Crowd-Control Supports: High-impact control units benefit from added durability to ensure their crowd-control skills land in later combat rounds.
4. Pure Utility Buffers: Leave pure buffers and healers at 6 stars until your core carries and tanks are completed. Speed boosts, energy generation, and debuff cleansing function effectively without high base stats.

To prevent severe fodder bottlenecks, build a starting lineup with diverse elemental affinities. Attempting to bring two units of the same element to 7 stars at the same time doubles your faction-specific fodder requirement and stalls both heroes.

Fodder Management Rules

Sacrificing viable natural 5-star ninjas to accelerate a 7-star breakthrough causes permanent setbacks to your roster depth. Apply these inventory rules before confirming any fusion:

• Promote 4-Star Base Units for Fodder: Upgrade natural 4-star heroes into 5-star cards using low-tier materials, then feed those upgraded cards into your 6-star candidates.
• Preserve Unique Kits: Never sacrifice natural 5-star heroes that possess rare debuffs, unique crowd control, or team-wide utility, even if they are not in your active starting five.
• Lock Key Copies: Use the inventory lock feature on every spare copy of high-tier heroes to prevent them from being consumed during batch fusion.
• Preserve Faction Auras: Check your active team's faction resonance bonuses before sacrificing spare units from the same element.
