Ghost of Yōtei
Child of the Mountain Trophy in Ghost of Yōtei
Solve all Mountain Reliquary puzzles.
Five Mountain Reliquaries, one in each region except Nayoro Wilds, each a stone pillar with four fox statues around it. The riddle on the pillar says where the foxes must face. Turning one statue often turns another, so make a manual save before touching any. The notes give a sequence that works from the untouched start.
PowerPyx's reliquary guide has screenshots of each reliquary.
