The quest "In the wolf's clothing" can make you sweat, because most players do not immediately guess what needs to be done to successfully complete it.
This side quest can be taken on the Skellige Islands. On the island of Hindarsfjall, the witcher is told about the sacred grove in which a monster named Morkvarg now lives.
The purpose of the quest is to find out what kind of creature it is and clear the grove. The passage does not take much time, although it has its own difficulties.
Investigation
For details, we go to a priestess named Jost. She reveals that Morkvarg is a cursed bandit. He robbed and killed everyone without any mercy, until one day he killed the high priestess Ulwe, who put a curse before her death.
Now he is a huge wolf, which is also immortal. Many brave men took on the task of destroying it or simply entered the tract in search of glory. None of them succeeded.
The priestess also talks about a witness who may know about the curse. His name is Todar, he was a novice at the shrine where Morkvarg was cursed.
We go to him for a conversation. He tells us how the curse sounded, and we go into the grove.
Meeting with Morkvarg
The corpses of our predecessors and the footprints of the beast are everywhere in the sanctuary. Sooner or later, the White Wolf meets the damned, kills him, but before dying, Morkvarg tells about his curse.
It says that he cannot be killed, and besides, he cannot eat or drink. It becomes clear to Geralt that the curse is multi-level and very powerful. The damned asks for help in exchange for a generous reward.
There are several options. You can wait for the second meeting with a huge wolf and, having defeated him, feed him your own meat. The curse will be lifted, but Morkvarg will die. You can go explore the sanctuary in search of new clues.
You should definitely visit the chapel, there will be valuable information about the past of the entire gang. It turns out that Todar is actually one of its members, who is fed up with the atrocities of the leader. He used a claw, an ancient talisman, and cursed it.
We go back for an explanation.
Brought to clean water
We find Todara in the same place. We immediately tell him that we know the truth. Further we will find out the details from him. He talks about the atrocities of the bandit leader and how he cursed him to end it.
It turns out that you can remove the curse by returning the fang to the damned. We take away the key to solving the problem and go back.
We finish the work
Returning to the grove, we do not find Morkvarg there. We go to the stream, which is regulated by two locks. We select the necessary positions and under the water we find the entrance to the cave, which was noticed from above.
There we see a morkvarg in our lair. Once again, we defeat him in a fight and give him the canine. The curse is dispelled, and the pirate is insanely happy, saying that the witcher deserves a reward.
Here we can decide whether to kill him so that he stops terrorizing the surrounding villages, or take what he promised.
You can complete the quest "In the wolf's skin" without any problems. You will not meet very dangerous opponents or incredibly difficult puzzles here, you just have to run around the island.
