Genshin Impact: Obtain Burning Firestones for Primal Flame Quest

After assisting Bona in purifying the Chu'ulel Light Core from Abyssal Corruption within Genshin Impact, players must 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 unlocks access to Tonatiuh, a floating island above Ochkanatlan’s Cradle of Fleeting Dreams. Reaching Tonatiuh completes the To the Sky-Road Quest and initiates The Other Side of the Sky Quest, requiring the collection of four Burning Firestones to obtain the Jade of Return.
