Guide
Head to the Sigil
Head east, passing by a treasure chest containing one Healing Potion Lv. 5 on the way. Enter the innermost chamber after the conversation just outside. There is no opportunity to save during this quest, nor are there any Signposts to exit the Runebarrows from.
Defeat the Sorcerer who has possessed the Mayor
Inside is the final boss battle against the Sorcerer. Defeat the Sorcerer only to have to defeat him again.
Defeat the Giant Sorcerer
Strategy
When the Giant Sorcerer lowers down and creates a blast is when it is weak. At no other point can an attack break through the barrier. Defeating the Sorcerer awards the player with the achievement 'This Treasure I've Found'.
Following the game credits, the game will auto-save a clear file for the player to use, taking the player back to Main Quest 29 After the Truth!, immediately prior to the point of no return, with additional quests available, one Critical Mastery and Impossible Luck item, as well as the option to select Hard Mode from CJ's lodgings in the Residential District.
Additional Critical Mastery and Impossible Luck items are granted each time this quest is completed. The quest is officially cleared after Post-Game data is created.
