Genshin Impact: Discover the Secrets of Burning Firestones (Flowing Primal Flame Quest Guide)

After assisting Bona in purifying the Abyssal Corruption from the Chu'ulel Light Core within Genshin Impact, players must then help her locate the Primal of Flame. Once found, Travelers must present two Pyrophosphorites – acquired during the Palace of the Vision Serpent Quest – to the Altar of Primal of Flame.

This offering opens a path to Tonatiuh, a floating island above Ochkanatlan’s Cradle of Fleeting Dreams. Reaching Tonatiuh completes the To the Sky-Road Quest and begins The Other Side of the Sky Quest, requiring Travelers to gather four Burning Firestones to obtain the Jade of Return.
