Devil by the Well

The Devil by the Well is a unique Noonwraith monster that is found in the town of White Orchard in The Witcher 3: Wild Hunt.

Background
''"The residents of the White Orchard had suffered more than their fair share of misfortunes. Passing armies have trampled their spring planting, a griffin had begun abducting their livestock, and the rotten icing on the painful cake, a Noonwraith haunted a nearby well. The Witcher could sense something bound her to this place, and that in order to send her off into ethereal realms would first need to kern her secret. Once that was done, he would have to prepare for battle - a Noonwraith is a demanding opponent. She can disorient her victim by binding him and creating mirror images of herself. These copies slowly suck their victims life energy - while their mistress remains untouchable. In order to defeat her, the Witcher could not rely on his silver sword alone - The Yrden sign would also be needed to trap her and force her to take on a material form." - ''Out of the Witcher journal in the Witcher 3 video game.

Walkthrough
Obtain the quest from the Notice Board in Crow's Eye (Woesong Bridge signpost). Talk to Odolan about the contract, he is located inside the largest home left of the notice board. If you discuss cost, he will pay you 20-coins and if you choose to do it for free he will reward you with an amethyst.

Travel to the abandoned village. There are no enemies here. Search the abandoned homes for loot, be sure to grab the journal. When finished, use your witcher sense to discover the scorched grass. Jump into the well (no enemies here) and find a bracelet. Climb out of the water to update the quest. Follow the stone path around to a smaller pool of water, dive in and follow the underwater tunnel. There are no underwater enemies or chests. Its a breathy swim so you have enough air to surface in a small lake next to an abandoned hut. Return to the abandoned village.

''NOTE: The Noonwraith will spawn at 12:00pm and will fly around the well during the daylight. You will need to see her ghostly image to update this quest. You cannot fight her, she appears just for you to preview her.''

After the ghost spawns, read the beastiary on Noonwraiths to update the quest. Search the (highlighted) huts for a pile of bones laying on the floor, examine it to update the quest. Using your witcher sense to find more clues examining the dragged blood, doorway, the ground next to the well, and rope tied around the well to view a cutscene and update the quest. Save your game.

Click on the body to burn it and the (Level 5) Noonwraith will spawn. Be sure to cast YRDEN axii because this is essential in defeating her. Lure her inside the axii circle and attack her with silver sword (for magical creatures & monsters). Upon her death, you will earn 50xp. Return to Odolan to complete this quest and earn another 50xp.

Optional: Though its not part of this quest (or any quest), if you run to the Herbalist's hut and ask her if she knew a "Claer" it will prompt a conversation then rewards you with many gifts-its worth the chat.

Trivia
You receive an amethyst if you refuse payment at the end of the contract.

You will fail this quest after the game's final chapter if never completed previously.
