Stellar Affinity Artifacts & Ship Energy
Turn affection into combat power without wasting resources.
Stellar Affinity’s pitch is blunt: strong emotions toward the girls keep the ship energized, and that energy transforms into divine artifacts capable of reversing battles. After the 29 July 2026 EROLABS launch, that sentence is the difference between an account that only collects CGs and an account that clears planetary docks. This guide explains how to think about the conversion loop in practical terms — sources, sinks, slot priority, and the mistakes that waste launch mail.
If you still need the full game loop, start with how to play. If your meters are high but modules are empty, you are on the right page.
Energy sources (what actually refills the battery)
- Spiritual interactions and threshold scenes on Hime Bonds
- Physical companion stage-ups on Cumpanions
- Stage clears and planetary progress (planet walkthrough)
- Event missions and carnival boxes (current events, launch rewards)
- Occasional code rewards (active codes)
- Soft currency support such as star-fragment packs (launch mail often includes a ~5000 class gift) spent into the girls who generate energy
Energy is not a pure shop bar you should tap with diamonds every hour. Star diamonds — including elite CBT 200% returns on qualifying accounts — are usually better reserved for banners chosen in gacha & summon.
The conversion mindset
Treat artifacts like interchangeable power modules sitting on top of rarity and levels:
- Generate affection on the girls you actually deploy.
- Convert when a slot or recipe is ready — do not hoard energy forever “for a perfect moment.”
- Slot the best module on your carry first (divine artifacts).
- Match effects to templates in best teams: burst for bosses, sustain for story pushes, AoE comfort for wave docks.
- Avoid equalizing every character’s gear — see progression priority.
The story free six-star path makes a designated girl rare and shiny; artifacts decide whether that rarity shows up in bullet-hell timers.
Combat usage tips by content type
| Content | Artifact bias | Notes |
|---|---|---|
| Planetary bosses | Burst / execute windows | Pair with pattern knowledge from combat & idle |
| Long story pushes | Sustain / shield-style effects | Reduces stamina wasted on retries |
| Farm / idle-assisted clears | Cooldown or AoE comfort | Speeds waves while harvest runs |
| Event challenge nodes | Counter modules if offered | Check events before rebuilding everything |
When a dock still fails after a conversion, change one variable only — module, bond level, or support — so you know what worked.
Economy link: artifacts vs gacha vs gifts
Energy and artifacts consume the same weekly attention budget as summons and intimacy gifts:
- If you are broke on upgrade mats, pause pulling and read currencies.
- If artifacts are fine but stages still fail, revisit roles on the tier list.
- If you just spent carnival gifts on five side girls, your carry’s next conversion will feel late — fix gift priority in beginner week.
- If login pulls (~200 campaign) just landed a new SSR, do not instantly strip the carry’s modules to “try her.” Prove the new girl on a flex slot first.
Newbie recruit rate-up should feed the same name you are pouring energy into. Split attention is how launch accounts feel weak despite generous mail.
Daily conversion routine
- Claim mail, login pulls, and carnival ticks.
- Bond mains (Talk / Gift / Mission via the bond checklist).
- Convert energy if any carry slot can improve.
- Push one to three active stages that benefit from the new module.
- Park idle harvest so mats for the next upgrade accumulate (combat & idle).
- Only then open banners with a written target.
Common conversion failures
| Failure | Result | Fix |
|---|---|---|
| Bonding without converting | High meters, low damage | Convert before another gift binge |
| Converting on side girls | Carry stays soft | Modules follow best teams |
| Buying energy packs early | Diamond drought | Use bonds + docks first |
| Ignoring story mats | Six-star shell, weak modules | Clear docks; spend fragments on the designate |
| Outdated client recipes | Missing buttons | Update via download & PC |

Energy is the bridge between romance systems and combat systems. Cross it daily, spend it on a narrow core, and planetary bosses stop feeling like a separate game from the harem fantasy.
Frequently Asked Questions
Quick answers to the most common questions.
Can I buy ship energy directly with real money?
Sometimes packs or stamina-like items appear, but value-check [currencies](/items/currencies/) first. Bonds and docks are the intended refill loop.
Do divine artifacts bind permanently to one character?
Follow the live in-game rules for your build. Until proven otherwise, assume carries deserve first upgrades and avoid spreading modules evenly.
Why is my damage low even with strong girls?
Usually weak artifacts, neglected Hime Bonds / Cumpanions, or mats spent on the wrong roster — fix energy conversion before more pulls.
Where are detailed item pages?
Start with [divine artifacts](/items/divine-artifacts/) and the [items hub](/items/) for currencies and upgrade materials.
