How Gacha Works in Blue Protocol: Star Resonance — Reroll, SSR Drop Rates, and Strategy

The gacha system in Blue Protocol: Star Resonance is one of the game’s most important progression mechanics — offering players powerful Battle Imagines, stylish cosmetic items, and special rewards through a layered summoning system.

While it resembles other anime-style gacha RPGs, Star Resonance features unique rules, pity thresholds, and class scaling that make understanding the system crucial for every player. Here’s everything you need to know about summon mechanics, drop rates, reroll strategy, and the best early pulls.

How the Gacha (Summon) System Works

In Star Resonance, the gacha allows players to summon Battle Imagines (also known as Echoes), costumes, and other collectibles using in-game currencies such as Bound Rose Orbs, Unbound Rose Orbs, and Will Wish Coins.

These summons come from limited-time or permanent banners, each with its own item pool and rarity tiers. The two main gacha types are:

Battle Imagine Gacha

• Contains Rare, Advanced, and Intermediate Battle Imagines.

• Used to obtain Echo-style items that enhance combat performance.

• Some banners feature rate-up Battle Imagines, such as Olvera or Tatta, with slightly higher drop chances.

Cosmetic Gacha

• Offers outfits, mounts, accessories, and emotes.

• Primarily cosmetic, but includes pity and duplicate exchange systems similar to Battle Imagine banners.

💡 Tip: Battle Imagine gacha directly affects gameplay power — focus your early pulls there before investing in cosmetics.

Official Gacha Rates and Pity Mechanics

According to Bandai Namco’s Star Resonance data (as reported by Icy Veins), the current Battle Imagine banner rates are:

Each 10-pull guarantees at least one Intermediate or higher rarity Imagine, and pity counters are banner-specific — meaning progress toward pity resets when banners rotate.

Pity Explained

• After 80 pulls, you are guaranteed a Rare Battle Imagine (top tier).

• After 20 pulls, you are guaranteed at least one Advanced Battle Imagine.

• Both pity systems ensure that even unlucky players can eventually secure high-value items.

Gacha Currency Breakdown

💬 Pro Tip: Don’t spend Bound Rose Orbs too early — wait for rate-up banners featuring the strongest Battle Imagines.

Optimal Reroll Strategy

If you want a strong start in Star Resonance, rerolling is worth your time — especially because Rare Battle Imagines have extremely low drop rates.

Step-by-Step Reroll Guide:

1. Complete the Tutorial: Play until you unlock your first free 10x summon.

2. Claim Pre-registration and Launch Rewards: These often include summon tickets and free Rose Orbs.

3. Summon on the Rate-Up Banner: Focus on banners featuring Olvera, Tatta, or current meta Rare Imagines.

4. Evaluate Your Pulls:

   • Keep the account if you pull a Rare Battle Imagine or multiple Advanced ones.

   • If not, restart with a new guest login and repeat.

💡 Speed Tip: Only link your account after you get your desired pull — it saves time when rerolling.

Recommended Early Rare Battle Imagines (SSR-Equivalent)

While many Rare Battle Imagines will rotate over time, several stand out for early builds:

💬 Note: The Stormblade class benefits the most from Rare Battle Imagines due to high scaling — while other classes perform decently with Advanced tier items.

Advanced Gacha Tips & Strategy

1. Pull in Multiples of 10: Pity and guaranteed drops are calculated per 10x summon, not single pulls.

2. Prioritize Battle Imagines Over Cosmetics: Early gameplay progression depends more on power than fashion.

3. Track Your Pity Count: Banners reset — so log your total pulls to avoid wasting orbs.

4. Use Duplicates for Upgrades: Duplicate Imagines generate Will Wish Coins, which can be traded for higher-tier gear.

5. Save for Meta Banners: Limited banners often feature Imagines with unique passives unavailable elsewhere.

Final Thoughts — Is It Worth the Pulls?

Blue Protocol: Star Resonance’s gacha system is fair by modern standards — the pity system ensures eventual rewards, and F2P players can obtain top-tier Battle Imagines through steady play.

However, the extremely low 0.15% top-tier rate means you shouldn’t chase every banner. Plan your pulls around limited events and reroll efficiently to start strong.

If you’re willing to be patient, Star Resonance offers long-term progression and flexibility — especially since you can change classes freely and make full use of the Battle Imagines you collect.
