By taking the Spiritway, which is unlocked at the end of The Forsaken Sea of Wisdom quest in Genshin Impact, you will travel toward the southern island called Flame-Melding Ritual Grounds. The Spiritway will drop you in front of a teleport point. Activate it and start heading south.

Use a flying character like Mavuika or Chasca, or indwell a nearby Qucusaur, to reach the island to the south. Upon entering the island, you will find another teleport point and a Tatankasaur next to it.

You can indwell the Tatankasaur and headbutt the rocks ahead to collect a Pyroculus and a loot chest. From there, continue toward the area marked on the map. You can use Tatankasaur’s charge ability to quickly ascend, as platforms marked with an upward arrow will boost its running speed.

How to Break the Seal in Sealed Site of Sacrifice Quest

To break the seal, you must create a straight path leading to it and charge up the way using a Tatankasaur. The stairs leading to the seal are scattered and must be repositioned by hitting them with Tatankasaur’s special charged attack.

• Look for a burnt red mark on the stairs and hit it with Tatankasaur’s ability to move them into place. If positioned correctly, a bright orange glow will appear.
• Except for the top stair, the rest will align easily.

For the top stair:

1. Push it to the right side. This will cause a nearby wall to break, revealing a hidden room.
2. Enter the room and activate a lever on the wall to move the floor backward.
3. Charge forward using Tatankasaur’s ability and find another lever to stop the floor’s movement.
4. Next to this lever, you will see a breakable wall. Charge into it to create an exit.
5. Finally, hit the left-side stair twice to move it into position, completing the staircase.
