Obtaining Archer’s Crest
Yaesha – Found behind an illusory wall in a room with water cascading from the ceiling in Endaira’s End.
When you approach the wall, you will see a flicker animation indicating that it is not normal. To climb onto the ledge behind the wall, however, you must use your vault/roll button. Follow the road, but keep in mind that the chamber isn’t empty. You may have to face some formidable foes first. After that, open the chest and take the ring.
Time-Saving Tip. This Dungeon has loads of other secrets, so if this one isn’t here for you there’s most likely something else you can go grab.
