Abandoned

Abandoned is a triumph for investigating the Mill, a Trivial Mystery in Forest of Echoes (a Shattered Realm from Season of the Lost). Worth 1 point.

How to complete

Open the "In Shadow" mystery chest first; the Mill is reached right after it.

Activate the Barrier Breach sign from the cave you just exited, and use the exit closest to the beacon.

Run left across the area, through the Taken slow field, and into the doorway ahead. Look for the turning waterwheel.

Defeat the enemies that spawn and open the chest.

Opening Trivial Mystery chests gives season gear and unlocks the triumph.
