Quick answer
A Blue Compass reacts while you move the Treasure Map marker toward its hidden destination. Test the main directions, follow the direction that lights the compass blue, and switch axis when the response stops. Use smaller movements when the map shows the interaction prompt is close.
Progression note
Compass totals and some collection areas include post-credits content. The guide keeps exact late-game destinations out of the quick answer.
How the Blue Compass works
Unlike a simple pointer, the Blue Compass behaves like a directional test. It responds while the map marker is moving along a useful line and turns off after the marker moves beyond it.
- Open the Treasure Map and move the marker in each major direction.
- Continue along the direction that makes the compass fill blue.
- Stop when the response disappears.
- Try the perpendicular directions from that point.
- Repeat with smaller movements until the map offers the interaction prompt.
Use small marker movements near the destination. Large movements make it easy to pass the point where the compass changes direction.
Where compass pickups are found
Compass pickups appear inside dark-blue crates in relic-hunting and crystal levels, plus selected post-credits dungeons. The crates may sit away from the shortest route, so check high platforms, hidden corners, and alternate paths.
Where to look for Blue Compasses
| Area | Where to look | Unlock |
|---|---|---|
| Relic-hunting levels | Check dark-blue crates away from the main route, especially hidden corners, high platforms, and alternate paths. | Sampler Dungeon |
| Crystal levels | Look for dark-blue crates and use the ZL level list to identify stages where the compass icon is still missing its check mark. | Sampler Dungeon |
| Selected post-credits dungeons | Three of the currently reported 24 compasses are tied to challenges available after the main story. | Late-game Sampler Dungeon |
This table explains the level types and tracking method. It is not a complete 24-location checklist. Exact stage coordinates will be added with original annotated captures.
How to check whether a level still has a compass
Open the Treasure Map, press ZL, and review the level list. The compass icon receives a check mark after the relevant pickup has been collected. A missing check gives you a focused level to revisit.
What compasses unlock
Compasses reveal Sampler Dungeons. These challenge stages use preset loadouts, often introducing a particular gadget or constraint. That makes a compass useful for progression even when the pickup does not immediately improve your current weapon.
How many Blue Compasses are there?
There are 24 Blue Compasses: 21 available through the main game and three tied to post-credits challenges.
