Starsea Call is Petit Planet’s gacha system, but unlike HoYoverse’s adventure games, it does not sell characters. It is the route to outfit sets, furniture and collectible Curios, which makes understanding its odds mostly a matter of decorating budget planning. All figures in this article were reported from the game’s final pre-release test build; treat them as announced data until the site can re-verify them in-game after launch day.
What you can pull
Three families of rewards come out of the system:
- Outfit sets: full clothing sets for your character.
- Furniture: pieces tied to themed series.
- Curios: collectible display items.
Banners come in a few flavours: the main Starsea Call banners rotate themed sets, while Sea Wish and Curio Sea Wish banners cover their own pools. Free tickets (including the Sea Whistles from the pre-registration rewards) can be earned through daily tasks, so free-to-play pulling is part of the design.
The odds, per pull
Each pull returns one result:
- About a 7% chance of the full outfit set in one pull.
- About a 93% chance of a single item from the featured set.
Two guarantees soften the variance:
- Every 10 pulls include at least one item from the featured set.
- Within a maximum of 100 pulls you are guaranteed the complete set.
The reported model also raises the full-set chance as a streak of pulls without the set grows: community reporting places the increase from around the seventh pull onward. Combined with the pity system, the effective chance of walking away with the full set per pull has been measured at roughly 13.57% once the save mechanic is taken into account.
No 50/50
If you know other HoYoverse games, the first question is always “what happens when you lose the 50/50?” In Starsea Call, the answer is: there is no 50/50 to lose. The featured set is the only set on the banner, so pity and guarantees feed directly into it. That makes the system considerably easier to plan around than a character banner.
The save mechanic
The system tracks accumulated full-set chance across pulls on a banner. If you pull partway into a pity stack and stop, that built-up chance is saved and carries into your next session on the same banner; the reported 13.57% combined figure includes this carried probability. Practically: stopping mid-streak does not throw away progress.
Duplicates become currency
Pulling an item you already own converts it into Curio tokens, a shop currency. Duplicates are not dead weight: they fund future purchases, but they are not a second copy either, so completing a set by brute force costs more than the pity ceiling suggests if you keep hitting singles you already own.
Budgeting notes for launch week
- Free first. Daily tasks hand out pull tickets; spend those before any paid currency.
- Decide set-versus-singles early. If you want the whole set, the 100-pull ceiling is your worst case; budget for it or wait for a banner you truly love.
- Watch the save counter. Because accumulated chance persists, returning to a banner mid-streak is stronger than starting a new one from zero.
Where these facts come from
Rate and pity figures were compiled from reports on the final pre-release test build and community deep-dives on HoYoLAB. They are announced/test-build data, not verified in-game values; the site relabels every figure as verified only after checking it in the live game after launch day.
