Tales of Symphonia Cheats :
Secret - Yuan's Ring Sidequest
Available: After defeating Rodyle at the Remote Island Human Ranch
The party is taken to Palmacosta and then on to the Sylvarant Base. From there, fly to Hima and enter the town. The scene seems to show that Yuan is looking for something, but he eschews them. Go to the summit of Fooji Mountains where you discover that Yuan is looking for a ring. Head to the Palmacoasta Human Ranch after completing Latheon Gorge and speaking with the Elven Storyteller. Lloyd finds Yuan there and gives him the ring.
