Stella Sora Gacha Rates Explained: Pull Math and Banner Value for F2P & Whales
Stella Sora’s gacha system stands out for its pull pricing, probability rates, and evolving banner structure. Whether you’re F2P or a whale, understanding the math behind every summon can help you maximize value, and avoid costly mistakes.
Gacha Rates and Banner Types
Stella Sora features several banner types:
- Permanent: Always available; expanded with each new Trekker.
- Limited/Rate-Up: Time-limited, featuring new or spotlight Trekkers and/or weapons.
- Weapon/Disc: For gear only, separate pool from character banners.
- Beginner: Improved rates and guaranteed S-tier options for new accounts.
| Banner | 5★ Rate | 4★ Rate | 3★ Rate | Spark (Guarantee) |
|---|---|---|---|---|
| Character | 2% | 8% | 90% | 120 pulls (non-transfer) |
| Weapon/Disc | 2% | 8% | 90% | 120–160 pulls |
| Beginner | Up to 4% | — | — | Guaranteed 5★ in 10 pulls |
- On a rate-up banner, it’s a 50/50 shot between the featured 5★ and a standard 5★ Trekker.

Pull Math: What Are Your Odds?
You have:
- A base 2% chance for a 5★ character per pull.
- A guaranteed pity (spark) after 120 pulls on a character banner, costing 36,000 Stellanite Dust.
- Single pulls cost 300 Stellanite Dust, double the 150–160 standard in most other gacha games.
- $100 USD isn’t enough for even 30 pulls; a spark costs upwards of $400 USD if fully purchased.
| Action | Dust Needed | Pulls | Guaranteed? |
|---|---|---|---|
| Single 5★ Try | 300 | 1 | No, <2% chance |
| 10-Pull | 3,000 | 10 | At least one 4★ guaranteed |
| Spark Guarantee | 36,000 | 120 | Featured 5★ on current banner |
For F2P, regular play offers roughly 100 Dust per day, not even a single pull, not counting limited launch rewards.
Banner Value: F2P vs Whale
F2P Players:
- Should always save pulls for high-impact limited banners, aiming for spark or near-spark to guarantee priority Trekker.
- Avoid weapon banners, which drastically split currency and are less impactful for free players.
- Use all codes, missions, and launch ticket events for “free” multis; “selector” tickets for best S-tier launch Trekkers.
Whales:
- Must spend $400+ for a guaranteed 5★, most of which will be off-banner without spark.
- Weapon banners add another layer of cost, not only do you spark for units, but also need 120-160 pulls for signature weapons to maximize performance.
Compared to Blue Archive and Genshin Impact:
- Blue Archive gives F2P players a spark every 2 months via regular play, Stella Sora offers far fewer free pulls, and requires both character and weapon sparks.
- Genshin’s average is also 180 pulls per spark, but at a lower cost per pull and more regular currency supply.

Final Advice
If you’re F2P: save for spark, pull only on top banners, and skip weapon pools. Whales: budget for multiple sparks if you want full meta setups. The system rewards patient, targeted summoning, know your math before you pull!
