The Watermill Hills treasure sits at the end of a Will-o-the-wisp trail in the forest north of Briar Sloughs. Chasing the glowing wisps starts the Wisp Treasure Hunt: Watermill Hills quest, walks Coen past a boss fight, and finishes at a chest tucked beside a cluster of dead bodies.
Quick answer: Fast travel to the Sloughside Mill Shrine, head west up the slope until the bright red wisps appear, follow them southwest to kill the Ravenous Bear, then keep chasing them northwest and back down east to reach the treasure chest. Opening it costs 1 in-game hour and completing the hunt grants 100 XP and one skill point.

Where to start the Wisp Treasure Hunt
The nearest fast-travel point is the Sloughside Mill Shrine. That waypoint unlocks automatically if you already investigated the mill to learn more about the rebels, so most players will have it before reaching this area.
From the shrine, turn west and climb the slope. The Will-o-the-wisps appear part way up. They glow bright red and are easy to spot, especially at night. The quest triggers on its own the moment Coen gets close to them, so there is nothing extra to activate.

Tip: If you want to check the loot before committing the hour, open the chest, look at what dropped, then reload your save to recover the spent time.
Watermill Hills treasure rewards
The chest can contain the following items.
| Item | Effect |
|---|---|
| Warrior’s Rush Amulet | Swordmastery ability cooldown and weapon damage |
| Linseed Oil | Common oil |
| Barley Beer | Stamina regeneration rate |
| Frugal Witchcraft Manual | Unlocks a perk upgrade in the Witchcraft skill tree after you read the book |
On top of the chest contents, finishing the Wisp Treasure Hunt: Watermill Hills quest rewards 100 XP and one skill point. The quest log updates to show the hunt as complete once you open the chest, which confirms the reward has been granted.

If the wisps never show up, you are likely on the wrong side of the shrine. Return to Sloughside Mill Shrine, head west, and climb until the red lights appear. The Ravenous Bear is the only real obstacle along the route, so level up your skills first if its red attacks are cutting through your health too quickly.
