Sun Palace

Era Future
The fight with Son of Sun is more of a puzzle than a straight up Boss encounter. You can't harm Son of Sun directly (though you can and should Charm the Black Mail away from it), but instead must attack the five smaller flames surrounding it. One of these will harm Son of Sun, and the rest will counterattack. Once you find the right flame, keep hitting it (with normal attacks) until the flames are reshuffled, then begin the process anew.

This can be a tough fight if you're not prepared, but giving everyone a Red Vest or Red Mail will help a lot. Other Fire-resistant Armor can work in a pinch, or you can use the Black Vest or Mail to absorb Son of Sun's one Shadow-based attack.
