Free 5-Star Character in Star Rail 3.7: Topaz, Ruan Mei, Luocha, or Save?

Honkai: Star Rail's Version 3.7 is set to launch soon, which brings thrilling new content alongside one of the game's most generous rewards yet: a free Golden Companion Spirit. This shiny token lets you snag a limited 5-star character (or an Eidolon upgrade if you already own them) from the Stellar Convergence shop, with no pulls required. With Topaz & Numby freshly added to the exchange list, players are buzzing about the best choice: the fiery Hunt DPS Topaz, the legendary Harmony support Ruan Mei, the reliable healer Luocha, or something else entirely?

How to Claim Your Free Golden Companion Spirit

It's simple:

Log in after the Version 3.7 update (expected November 5, 2025) until the end of Version 4.0.
Head to the Travel Log and claim your 1x Golden Companion Spirit from the Stellar Companions event.
Exchange it in the Stellar Convergence shop (under Store) for your prize.

Bonus: Top up Oneiric Shards during events like Cherished Recollection for extras, or convert surplus maxed-Eidolon dupes (via Silver Companion Spirits) into more Goldens. Spirits don't expire, so no rush, although the free login window has a deadline.

What's Available? Full Exchange Options

One Golden Companion Spirit = 1 copy of a 5-star character (base or Eidolon) or 2 Variable Dice. Focus on these limited 5-stars:

Ruan Mei (Harmony: Ice) – Break Effect booster extraordinaire.
Luocha (Abundance: Imaginary) – Auto-healing sustain king.
Topaz & Numby (Hunt: Fire) – Follow-up attack specialist, newly added in 3.7.

Plus 7 standard 5-stars (e.g., Bronya, Himeko, Bailu, Gepard, Clara, Welt, Yanqing), which are perfect fillers if you're missing early-game staples.

Breaking Down the Top Contenders: Who Should You Pick?

Your choice hinges on your roster gaps, playstyle, and the 3.7 meta (dominated by hypercarry DPS like Phainon/Castorice, superbreak teams, and FUA setups). Let's tier them up using recent data from Game8's 3.6 list (still relevant pre-3.7) and community buzz.

1. Ruan Mei (SS Tier Support – Top Priority)

Why her? Universal Break Effect/DMG++ buffs, SPD boosts, and DMG% amp make her a staple in 80%+ of endgame teams (MoC, PF, AS). Her E1 adds extra DEF shred, which is huge for any DPS.
Meta fit: Excels in break-heavy 3.x content. Even with new supports like Lady D emerging, she's irreplaceable for most.
Pick if: You lack her (or E1). Best overall choice for F2P/newer players.
Skip if: You have E1+ and hypercarry alternatives.

2. Luocha (S Tier Sustain – Strong Second)

Why him? Effortless healing via auto-attacks, with no energy fuss. Pairs perfectly with aggressive teams in high-damage modes like Anomaly Arbitration.
Meta fit: Sustain is eternal; he's top-tier without relics eating your soul (unlike Huohuo).
Pick if: No dedicated healer. E1 Luocha is a luxury for 3-team clears.
Skip if: You run Fu Xuan/Gallagher/Huohuo.

3. Topaz & Numby (S Tier DPS – Niche Pick)

Why her? Numby's FUA ramps insane single-target shred. Great in Feixiao FUA teams.
Meta fit: She's just a bit worse than Cipher overall but outperforms both Moze and March 7th in Feixiao setups, offering strong generalist performance with consistent follow-up attacks and damage amplification.
Pick if: Feixiao main without her, or Fire Hunt lack. Otherwise, skip, and save for future shop adds.
E1 value: ~18% Feixiao boost, but still niche.

Standards or Save?

Bronya/Himeko/etc.: Grab if missing (e.g., Bronya for ATK buffs). But limited > standards.
Hold off? Shop rotates (more limited incoming?). Spirits persist, so wait for must-haves like Sparkle/Huohuo.
