Sacrificial Offering is a side quest in Genshin Impact. In this guide, you will learn how to complete that quest.
You will first need to go to this location on the map, as shown in the image below.

After getting there, you will find an abandoned shrine and three ghosts. You need to line up three ghosts with foxes statues.

You have to go to the shrine for the first one, and you will find him in front of the shrine. Now you have to interact with the ghost, and it will go to the fox statue.

After that, you need to turn around and go further, where you will find the next ghost standing on the stairs on the front side of the statues, as shown in the image below.

After reaching there, interact with the ghost, then he will leave and go to the statues.
The next one is on the top of the abandoned shrine where you find the ghost, and then you need to interact with it, and it will go to the fox statues, same as the previous ones.

The next one will be at the backside of the statues, and it will be standing alongside the tree.

Now you have to interact with it as well, and then this will spawn the major item and the chests as well.
Now you have to go to the shrine at the top of the mountain. When you reach there, you will find a woman, interact with her, give you the item, and then ask you to go back to the statues and find what happened.

After reaching back down, you will find some new blue statues, and the first one is near the fox statues, as shown in the image below. You will have to interact with it as well.

The second one is near the shrine, so you have to interact with it, as shown in the image below.

Now you need to head to the third one, located at the entrance of the shrine.

You have to go to the path down where you find the mini shrine for the next one. There you will find a blue statue, so interact with it and move forward.

You have to go to the big fox statue; you will find the last blue statue on the right side of the fox statue.

After that, you need to go to the big fox statue and interact with it as shown in the image below.

After interacting, it will provide you with 3 options in a sequence, as shown in the image below.

You have to get the ward from the shrine, and then you need to go to the second spot after the barrier to break the curse.

After reaching there, you will find a broken entrance right in front of you next to the gate. You have to pass through the cave, push the ward, and you will get a prayer puzzle.

The puzzle is straightforward; the middle one is a two and the rest are three, and you can use the same one twice as well. Also, make sure that the outside ones are three and the middle’s two. And then you have to activate it, and you will be able to get a fight.

After beating the enemy, the quest will be completed.
