Directions refer to the recorded view. Reflect means your configured reflection action; no native keyboard binding is assumed. This is an observed landmark route, not a native-game playtest. Counted mirror pushes are corroborated by the matching community layout; ordinary walking counts are not exhaustively transcribed.
- Walk around the upper crystal via its west side and cross the wooden walkway. Approach the mirror from the north and push it south one tile. Its row aligns with the lower horizontal stretch of the upper wooden route (9:56).
- Return to the upper crystal. Push it east one tile, get below it and push it north to the wooden-route row. Push it east onto the second wooden tile from the left on that horizontal stretch (10:03).
- Reflect the crystal into the water well south of the right island. It sinks at 10:05. Bring the lower crystal east one tile, then north and east onto the same wooden staging tile. Reflect again; the second crystal stands on the first offshore at 10:12.
- Return to the mirror and push it south one more tile. Its preview now points at the south-facing wooden stub. Reflect the standing offshore crystal onto that stub (10:17–10:18).
- Walk back around the wooden route and get north of the crystal. Push it south one tile into the water gap, where it sinks. Cross it and continue south to the exit. The trader occupies the circle at 10:22; a gold ring and transition follow at 10:23.9:51–10:24Spoiler clip
