In this guide, you will come to know how to use a SHADOW Stone and then recover the Spirit Vessel Location in Fortnite.
First, you have to go to the left side of the dirty docks, as shown in the image below.
When you get there, you have to find the shadow cube on the side of the mountain. Interact with it, and it will turn you into a ghost shadow. You have to go to the top of the mountain towards the dirty docks. While you are going to the dirty docks from the top of the mountain, you will see two huge trees, as shown in the image below.
You will find a small shrine near the trees, and you will see a vase in that shrine layout. Interact with it, and it will recover the location of the spirit vessel. Then you can complete the quest, as shown in the image below.
