Genshin Impact Guide: Acquire Burning Firestones in Primal Flame Quest

In Genshin Impact, after assisting Bona in purifying the Abyssal Corruption from the Chu'ulel Light Core, players must help her find the Primal of Flame. Once located, Travelers must offer two Pyrophosphorites (obtained 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 acquire the Jade of Return.

Acquiring the Four Burning Firestones:

Burning Firestone #1

The first Burning Firestone is obtained automatically during a cutscene with Bona and the Little One after reaching Tonatiuh. Follow the Little One across a raised bridge to continue.

Burning Firestone #2

The second Burning Firestone is on the northeastern isle. Players must manipulate floating isle mechanics to extend bridges, raise lifts, and overcome challenges including combat and puzzles to reach it. Along the way, collect a Common and an Exquisite chest.

Burning Firestone #3

To obtain the third Burning Firestone, manipulate floating isle mechanics to access the northern isle's lower level. Follow the Little One, then track the Secret Source Sentinel carrying the Firestone to the southwestern isle. This involves using a Qucusaurus to traverse the area, activating mechanics, and navigating platforms before returning to the Altar.

Burning Firestone #4

The final Burning Firestone is located on the northwestern isle's upper level. Players must use Bona's assistance to reach the upper level via a bridge, then overcome another puzzle and combat encounter before retrieving the stone and returning to the Altar. A Precious chest is also available for collection.

Offering all four Burning Firestones to the Altar completes The Flowing Primal Flame Quest, transforming the Jade of Return into a Golden Entreaty. The Dragon of the City of Flowing Ash then appears, leading players to the Nursery of Nightmares to finish The Other Side of the Sky Quest and earn 50 Primogems.
