Stella Sora Tier List: The Elite Trekkers for v1.1

This ranking assesses a Trekker’s performance as an on-field Main Unit, prioritizing high damage output, utility, and ease of building, which directly translates to a better return on investment for your resources.

S-Tier: Game-Changers and Core Investments

These Trekkers offer unmatched performance and should be the primary targets for your reroll strategy and early-game Stellanite Lumina spending. They possess kits that either trivialize content or unlock high-synergy team compositions.

• Gerie (Terra – ★5): The undisputed king of AoE burst damage and Terra Mark detonation. Gerie’s ultimate is a massive, high-impact ability that can clear entire rooms of enemies, securing a fast path through the Monoliths. Investment Priority: MAX.
• Shia (Lux – ★5) – NEW: The latest addition. As a Lux-elemental Vanguard, Shia brings powerful, sustained, and elegant attacks with her mystical drones. Her kit, specifically designed to synergize with the new ★5 Runic Disc “Ripples of Nostalgia,” offers incredible burst potential, making her a high-value financial investment for any player.
• Chitose (Aqua – ★5): The definitive Aqua-elemental DPS. Chitose excels at applying the “Chill” debuff with high hit frequency, leading to frequent “Freeze” status effects. This crowd control combined with her consistent damage output makes her essential for high-tier boss fights.

A-Tier: Exceptional Sub-DPS and Core Utility

A-Tier Trekkers are robust, versatile, and often form the crucial support or sub-DPS role in top-tier teams. They are highly efficient early game investments and provide excellent financial stability to your roster.

• Nazuna (Terra – ★5): The best offensive support unit in the game. Her plushie summons and powerful post-Ultimate ATK buffs are mandatory for maximizing the damage output of any Terra Main Unit (like Gerie). She is a vital piece for ultimate team guide synergy.
• Freesia (Aqua – ★5): A strong off-field damage dealer with good mark spreading. While she has mobility issues as a Main Unit, her Support Skill and Ultimate provide constant, reliable damage, making her a safer investment for pure sub-DPS utility.
• Minova (Lux – ★5): A fierce melee carry whose power peaks in the mid-game. She offers powerful front-loaded damage and is an excellent damage output source for players who prefer aggressive, close-range combat.

B-Tier: Strong 4-Star Options and F2P Staples

These Trekkers are the bedrock of any successful free-to-play guide. They are powerful when built correctly, easily obtainable, and represent an intelligent use of lower-rarity investment materials. Their value often increases significantly with duplicate pulls (Potentials).

• Amber (Ignis – ★4): A consistently strong, free-to-play-friendly marksman. Amber’s ability to scale hard with her dupes (Potentials) makes her a fantastic early game investment with one of the most reliable damage output kits among all 4-stars.
• Flora (Ignis – ★4): An elite 4-star support unit. Flora provides critical team buffs, particularly Crit Rate/Crit Damage boosts, making her an essential part of any Ignis team and a smart strategic resource management choice.
• Tilia (Lux – ★4): High-frequency stun utility. Tilia’s ability to consistently disrupt enemies with stuns and her team ATK buffs make her an often-underestimated investment in high-tier content where crowd control is key.

The Ultimate Reroll Guide: Maximize Your Starter Pulls

Stella Sora is generous with its starting rewards, providing new players with the “Opening Act” banner, which offers a guaranteed 5-star selection after up to 200 pulls and 5 saved results. This system makes the reroll strategy extremely efficient and critical for new accounts.

Step-by-Step Reroll Method (No Email Required):

1. Complete the Prologue: Launch the game and progress until you unlock the Summon feature (The “Opening Act” banner).
2. Execute the 200 Free Pulls: Use all available free pulls on the “Opening Act” banner. This banner allows you to select one of your 20 ten-pull attempts to keep.
3. Target the S-Tier: The optimal reroll strategy is to secure at least one S-Tier damage dealer (Gerie or Chitose are excellent choices) and a high-value 4-star Support (Flora or Tilia) in the same 10-pull result.
   • Ideal Pull: One ★5 Trekker from S-Tier + Two ★4 Trekkers from A/B-Tier.
   • Note: The new character Shia is on a limited banner and generally not available on the permanent “Opening Act” reroll banner. Save your Stellanite Lumina for her limited banner after securing a strong permanent unit.
4. Save and Confirm: You can save up to five results before choosing. Once you have a desirable pull (S-Tier DPS + A/B-Tier Support), select it and bind your account.
5. Continue with Free Gems: After your guaranteed selection, claim all Mail rewards (which include free Stellanite Dust and Tickets) and use them immediately on the limited Shia banner for a chance at the newest S-Tier unit. This two-pronged approach guarantees a powerful starting roster and maximizes your early game investment.
