Alvastia Chronicles

Pretty self explanatory. You’ll find chests thorough out the world as you explore in buildings and outside. You can track this challenge by pressing and then clicking on the trophy icon in the bottom right corner.

This is not track on the Xbox achievement tab

Open as many chests as you can and be on the lookout for hidden walls/paths. If wall tile will look like it’s cracked, more than likely it’s a hidden path.
