+2 retrieving, +2 filling with water, -2 drinking from bucket
You must have the dagger to retrieve the bucket. You can retrieve the bucket from above the well or down inside it. In either case, use the dagger on the rope tied to the bucket. The image to the left demonstrates where to use the dagger to retrieve the bucket. You can fill the bucket in the underwater cave immediately before the Dragon's Lair (pictured on right).
