Stella Sora, the upcoming light-action RPG gacha game from Yostar Games, is set to launch globally on October 19, 2025, at 19:00 UTC-7. Available on PC, iOS, and Android, the game puts players in the role of the "Tyrant," teaming up with charming female characters known as Trekkers to explore massive Monoliths in a roguelite-style combat system reminiscent of Hades. With top-down action, artifact collection, and gacha mechanics for summoning Trekkers, it's poised to attract fans of anime-inspired adventures and strategic team-building.

As the release date approaches, pre-registration has surpassed 8 million, unlocking rewards like free pulls and a 4-star character. Gameplay revolves around assembling teams of Trekkers, each with unique elements (Aqua, Ignis, Lux, Terra, Umbra, Ventus), styles (e.g., Adventurous, Collector, Steady), and factions (e.g., New Star Guild, Grace Imperium). Trekkers wield skills and ultimate abilities, enhanced by equippable Discs (weapons) that match elements for bonuses.

Since the game hasn't launched yet, this release day tier list is based on beta tests (CBT), leaks, community discussions, and pre-release analyses from various sources. Rankings focus on overall viability, damage output, synergy, and utility in early-game content like Monolith raids. Expect shifts post-launch as balance patches roll out and more data emerges.

Understanding the Tiers

  • S-Tier: Meta-defining Trekkers with exceptional damage, survivability, or support. Prioritize these for smooth progression.
  • A-Tier: Strong alternatives with great potential; excellent for filling team gaps.
  • B-Tier: Solid for beginners but may require investment; replaceable as you pull better units.
  • C-Tier: Niche or underpowered; use only if needed early on.

Rarities range from 4-star to 5-star, with elements and styles influencing builds. Not all 25+ announced Trekkers may be available at launch, but here's a comprehensive list based on available info.

Top Picks and Strategies

Focus pulls on S-tier banners like Freesia or Mistique for day-one dominance. Build elemental teams (e.g., Aqua for sustain, Ignis for DPS) and match Discs accordingly. Launch rewards include 140 pulls, two 5-stars, and two 5-star Discs, so reroll if needed for meta starters.

Stella Sora's roguelite elements mean experimentation is key—tiers are guides, not gospel. Stay tuned for post-launch updates as the meta evolves. Happy trekking!
