The in-game description says
A mask inspired by those fun-loving Koroks. It shakes when one is hiding nearby. If sold, this rare find can't be replaced.
Which is all well and good but I'm not sure is strictly accurate, or at least light on the details.
- Is there any sort of directional component, or is it simply proximity based?
- Proximity to what? Is it relative to the Korok itself, the puzzle that reveals the Korok, or both? I have noticed that around the tree stump/yellow ring puzzles, the mask will shake both at the stump and near the ring itself (where the Korok is actually located), but I don't know if it will shake near the ring if it's not currently visible. If the mask starts shaking and I can't find a likely looking puzzle, should I start looking for tree stumps that could potentially be rather far away?
- What sort of three dimensional awareness does the mask have? I've seen at least one "push the boulder into the hole" puzzle where the mask was shaking on a cliff high above the location of the Korok, near the boulders that needed to be pushed off the cliff.
- Does the mask respond the same to every Korok, or does each Korok puzzle have its own defined area which trigger the shaking? (I.e., if the mask shakes can I say "there is a korok within
$distancefrom my current location", or do I have to be more discerning with my assessment?)
- Anecdotally it appears that the mask will begin vocalizing when you're close enough, but what counts as "close enough" I have no idea.
