Achievements Guide
There are 21 achievements. Only one, Power Napper, is not part of 100%: just stand still for a cumulative hour. Nothing in the game is missable — every star, gem and secret can be collected later.
There are 21 achievements in Isles of Sea and Sky, and effectively all of them come from simply playing — collect stars, wake the four spirits, finish the hunt. Nothing is missable, and only one is not part of 100%: Power Napper.
Story and travel
| Achievement | What it takes |
|---|---|
| Turtle Rider | Take your first ride on the giant turtle — right-most side of the starting island |
| Rock Climber | Set foot on Stoney Cliffs, north of Ancient Island |
| Tidepooler | Set foot on Tidal Reef (needs the 5-star gate; head far left of Stoney Cliffs) |
| Firewalker | Reach Raging Volcano (15-star gate) |
| Ice Climber | Reach Frozen Spire (30-star gate) |
| Pathfinder | Enter the Sanctum after all four spirits are awake |
| Voyager | Visit 16 islands (added in v1.2 — includes the mini-islands) |
The four spirits
Waking each great spirit needs six matching elemental gems; each wake-up is an achievement:
- Rock and Roll — earth elementals, Stoney Cliffs
- Slip and Slide — water elementals, Tidal Reef
- Turn and Burn — fire elementals, Raging Volcano
- Huff and Puff — ice elementals, Frozen Spire (the wind spirit sits at the island's centre; you need bird access to get there)
Stars, runes, gems
| Achievement | Threshold |
|---|---|
| Starman Junior | 25 stars |
| Starman | 50 stars |
| Starman Deluxe | 100 stars |
| Final Starman | 120 stars — everything, including the Mysterious Update's 11 new stars |
| Master of Runes | All six rune stones (upgrades and runes) |
| Gemologist | Collect twelve gems of each elemental colour — obsidian does not count |
The Mysterious Update trio
The post-game collectibles have their own tiers:
- Insight — 10 pyramidions collected
- Illumination — 20 pyramidions collected
- Enlightenment — all 30 pyramidions (full guide)
The odd one out: Power Napper
Power Napper has nothing to do with 100% completion: spend a cumulative one hour doing nothing — the game tracks idle time across your whole save. The community's practical advice: do it deliberately, parked somewhere safe, ideally while a real-world hour passes. If you play in long calm sessions it will happen on its own.
FAQ
Can I miss any achievement? No. Every collectible, star and island can be revisited after the credits, and meta puzzles regenerate if you fail them.
Do I need the Mysterious Update achievements for "100%"? Only if your definition of 100% includes the post-game layer. The base-game completion (109 stars and the original collectibles) does not touch the pyramidion hunt.
