Place the reflected destination
The official overview associates the Trader with the eastern Mirror Isles. A mirror exchanges characters and objects with their reflections, and increasing distance from the mirror projects the reflected position farther away. Your starting position is therefore part of the travel calculation.
Check safety before travelling
In the recorded demo Q&A, an unsafe mirror destination can drown the character. Inspect where the mirror ghost stands before using the swap.
When there is more than one copy
NoLucksGiven’s demo narration reports that losing one duplicate prevents clearing the room. Keep the other copies’ situations in view rather than solving only for the character nearest an exit. This caution is based on that player’s demo observation.
