Stellar Affinity Currencies & Resources

Stellar Affinity economies mix premium currency, summon tickets, stamina/energy items, bond gifts, and upgrade materials. Client names vary by language pack (English marketing vs Korean 성간의 유대 vs Chinese 星慾姬絆 labels), but sinks stay similar. After the 29 July 2026 EROLABS launch, learn the difference between star fragments (碎星) style fuel and star diamonds (星鑽) before you tap a banner.

Currency map

Resource	Primary use	Do not waste on
Star diamonds / premium gems (星鑽)	Limited banners / value packs	Random off-banners
Star fragments / general fuel (碎星)	Levels, crafts, broad progression	Panic shop cosmetics
Tickets	Targeted summons	Day-one multi-pulls without a plan
Stamina items	Planet farming	Hoarding past cap forever
Bond gifts	Hime Bonds, Cumpanions	Spreading across 30 girls
Upgrade mats / books	Carry first	Even distribution
Event shop tokens	Timed unique pieces	Leftover conversion without reading rates

Launch injections (usually not codes)

Injection	Approximate value	Claim path
Server fragment gift	~5000 碎星 after CBT clear goal	Mail — launch rewards
CBT spender return	200% 星鑽 value, same account	Mail
Login pull campaign	~200 pulls across window	Login UI — beginner week
Seven-day carnival	Mixed tickets/mats	Event board
Public gift codes	Sparse / variable	Redeem — active codes

If you paste fragment mail text into Redeem, it will fail. Use how to redeem only for alphanumeric keys.

Spending rules

1. Bind account (download guide).
2. Finish tutorial systems (how to play).
3. Decide reroll fate (reroll).
4. Lock newbie recruit / story free-core target (gacha & summon).
5. Pull only toward tier list goals wired in team builds.
6. Keep a gem reserve for sudden current events banners.
7. Burn stamina on a combat & idle rhythm instead of letting caps rot.

Currency discipline is how F2P captains stay competitive with whales who only chase sparkle.

Worked examples

Example A — F2P day-three: You claimed fragment mail and three login ticket batches. Carry is chosen. Spend fragments on levels/skills, put tickets into newbie recruit only, gift bond items to carry + anchor, ignore cosmetic shop.

Example B — CBT return captain: Mail shows a large 星鑽 pile. Screenshot it. Finish the same F2P plan first. Only then allocate a written diamond budget toward a limited support that completes best teams. Do not celebrate by emptying the wallet on the standard banner.

Example C — Empty codes week: Active codes shows no strings. You still have carnival tokens. Tokens buy carry books in the event shop; leftover stamina becomes combat & idle clears. No coupons required for a productive night.

Caps and rot

If stamina or energy items are near a cap, burning them on comfortable farms beats “saving for a perfect node” you will not reach this week. Rotten stamina is the quietest way to waste launch generosity.

Region labels and double-counting traps

Screenshot wallets after big mail days so you do not redeem a code, claim carnival, and buy a pack while undercounting what you already gained. Double-counting creates false poverty and panic purchases. If your client shows both English and CJK labels for the same pile, still count it once.

When active codes finally lists a string, add the reward to the correct row in the currency map before spending. Ticket codes are not fragment codes; mixing them in your head is how people “lose” resources that are sitting in another tab of the bag.

Shop timing

Event shops beat permanent shops while timers run. Permanent shops beat panic banners when you are undecided. Fancy limited packs beat nothing if your carry artifacts are empty — finish divine artifacts craft goals first.
