Stellar Affinity Planetary Adventure Walkthrough

Each time the Stellar Affinity ship docks, you enter an independent planetary adventure. After the 29 July 2026 EROLABS launch, those docks are also the spine of free progression: story cultivation toward a six-star core, carnival clear missions, and the stages that prove your affection-powered artifacts actually work. This walkthrough focuses on completion strategy rather than spoiling every scene in 성간의 유대 / 星慾姬絆.

Use it when a node bricks you for more than two honest attempts. For the menu loop that feeds docks, see how to play. For shooting versus offline harvest timing, see combat & idle.

Dock checklist (every planet)

1. Claim offline harvest and dock bonuses before you spend stamina.
2. Scan side objectives — note which ones drop bond gifts versus pure vanity.
3. Update spiritual and physical affection if energy feels low (Hime Bonds, Cumpanions).
4. Confirm carry artifacts using the logic in artifacts & energy.
5. Deploy a story template from best teams, not a museum roster.
6. Clear the critical path first; return for 100% pickups after a power spike.
7. After the boss, dump mats into the story free six-star designate via progression.

Skipping steps 3–4 is why captains say “the planet is unbalanced” when the ship battery is simply empty.

How planetary adventures fit the launch economy

Launch lever	Why docks matter
Story free six-star path	Main pilgrimage mats arrive from advancing docks, not from living in the banner UI
Seven-day carnival	Clear tasks often want planetary stages — pick ones that also progress story
~200 login pulls	Bank them; docks tell you which support role you still lack
Star-fragment mail (~5000 class)	Spend into the girls who just cleared the last wall
Newbie recruit rate-up	Prove the carry on a real boss before chasing a second DPS

If you are still deciding whether to reset, finish one honest dock on the account before another reroll attempt — some “bad” pulls still clear early planets with correct bonds.

Stubborn stage diagnostics

Symptom	Likely cause	Fix
Waves take forever	Weak AoE or idle mats never invested	Add AoE from roster; spend harvest
Boss one-shots you	Missing sustain or artifact defense	Swap support; upgrade carry modules
You dodge well but damage is low	Energy never converted	Bond + convert before grinding
Out of stamina	Mis-spent retries	Use codes carefully; idle overnight
Underleveled everywhere	Even upgrades	Follow progression
Pattern illegible	Client stutter / old build	Update via download & PC

Bullet-hell walls are real, but many launch complaints dissolve after one artifact conversion and a focused gift session.

Exploration priorities inside a dock

1. Upgrade mats that feed the current difficulty band
2. Bond gifts for the deployed core
3. Story flags required to open the next date or pilgrimage beat
4. Event currency nodes during current events
5. Vanity collectibles last

Route efficiency beats completionism on your first visit. You can return after idle harvest and carnival rewards raise the floor. Captains who 100% the first planet before unlocking energy conversion often burn the stamina the seven-day carnival wanted for later docks.

Mid-dock bonding protocol

When you bounce twice:

1. Leave the stage — do not spend a third stamina “to see.”
2. Run Talk / Gift ticks on the deployed carry (bond checklist).
3. If a Cumpanions stage-up is one gift away, finish it.
4. Convert energy if the UI allows.
5. Re-enter with the same team unless diagnostics pointed at a role gap.

This five-step reset is faster than writing the planet off as paywalled.

After clearing a planet

• Reinvest materials through items and currencies into the same core.
• Raise affection on the girls who starred in that arc — story cast overlap is not an accident.
• Check patch notes for new docks, difficulty layers, or temporary scene locks.
• Revisit gacha & summon only if a role is still missing after story mats landed.
• Skim review expectations if you are evaluating whether the dock cadence fits your schedule.
• Park idle harvest before logout so the next planet starts with full crates.

Multi-planet campaign mindset

Treat the pilgrimage as a chain of proof tests for one account plan, not as twelve separate games. The carry you chose during newbie recruit should still be the carry on planet three unless a patch radically shifts roles. Event planets may ask for a flex counter — borrow from team builds, then return to the story core.

Planets are the story chapters of Stellar Affinity. Clear them with a dock checklist and the harem fantasy stays fun instead of becoming a wall you blame on gacha alone.
