In The Witcher 3: Wild Hunt, how to make the perfect ending of a contact between the three Witcher demons can be referred to as follows:
The mission is on the island and is triggered after meeting Yennefer's ex-boyfriend. After triggering the mission, follow the prompts to go to the island to find the lord.
Go out and give the sword to Caris and go down the mountain with her to ask the lord to learn the truth. The lord asks Jerlok to put the sword on his brother's bones.
During the battle, the lord will be frightened and run after him. Use the seal to calm him down and then go back to kill the demon. You can complete the mission with Caris when you go out and achieve a perfect ending.
