In Mirren: Star Legends, your heroes, known as Asters, are the cornerstone of your success. Excelling in both PvE and PvP modes hinges on your ability to strategically upgrade and enhance these heroes. The hero progression system may initially seem daunting, but with the right approach to upgrades and resource management, you'll unlock the full potential of your team. This comprehensive guide offers clear insights into hero progression, explains the talent system, provides tips for optimizing resource usage, and ensures your upgrade choices significantly boost your combat prowess.
Understanding Hero Progression
Hero Star Ratings and Their Importance
Heroes in Mirren are categorized by star ratings, ranging from 3-star to 5-star:
- 3-Star Heroes: Easily obtainable, they have lower base stats and limited growth potential.
- 4-Star Heroes: With stronger stats and more versatile skills, they are well-suited for the mid-game.
- 5-Star Heroes: These are the rarest, boasting the highest base stats and significant upgrade potential, crucial for tackling endgame content.
While 5-star heroes are ideal for long-term progression, you can effectively navigate the early stages by focusing on upgrading strong 4-star heroes until you summon higher-tier Asters.
Enhancing Hero Levels
Heroes level up by using resources known as Aster Tears, which greatly enhance their stats:
- Leveling Up: Increases HP, ATK, DEF, SPD, CRIT, and CDMG, directly affecting their performance.
- Aster Tears Acquisition: Earned through regular battles, completing missions, participating in events, or through mana conversion.
To maximize efficiency, prioritize leveling a core team first. Spreading resources too thinly across many heroes can hinder your overall progress.

Gear Synergies and Hero Upgrades
Gear plays a crucial role in enhancing upgraded heroes. The right synergy between gear and talent selection can significantly boost your hero’s effectiveness:
- Damage Dealers: Equip gear that enhances ATK, CRIT rate, and CDMG.
- Tanks: Prioritize gear that boosts HP, DEF, and damage reduction.
- Support Heroes: Opt for gear that increases SPD, HP, and healing effectiveness.
Proper gear-talent alignment can dramatically increase your combat efficiency, especially in challenging encounters.
Strategic Tips for Efficient Progression
- Elemental Synergy: Upgrade heroes representing each elemental type to ensure you have the flexibility to counter various enemy compositions effectively.
- Ultimate Skill Upgrades: Prioritize upgrades that enhance ultimate abilities, as these can significantly influence battle outcomes.
- Event Participation: Actively participate in events to acquire exclusive upgrade materials, which can save resources and enhance hero progression efficiency.
Common Mistakes to Avoid
- Spreading Resources Too Thinly: Concentrating upgrades on fewer, stronger heroes is more efficient than weakly upgrading many heroes.
- Ignoring Talents: Always allocate talent points thoughtfully; neglecting them can severely limit hero effectiveness.
- Overlooking Daily Logins and Events: Missing these can limit resource acquisition and slow your progression.
