I've gotten to the end of the game now, right before the Final Boss, but before I go to my final battle I'm wrapping up the Side-Quests of the game and one of them is the Mysterious Jewel Side-Quest.
Sadly I imagined to get only 16 out of the 23 Jewels that exist but I'm not sure where to start looking. I know I've gotten some from Aifred's Treasure, some drawers, and my most recent ones from large and uncommon monsters in Elympios.
Can someone list me all of the locations to find each and every one of these jewels so I can backtrack and start looking for them and get the missing 7 I need. --- "Behold the power of... the Nazo Virus..."
