Dream potion

The Potion of Shared Dreaming is used in the Dream Mentor quest. The Oneiromancer tells Cyrisus and the player that the potion will send them to Dreamland. The potion puts the player in Cyrisus's dream and binds the two subconsciousnesses together.

With the two minds melded as one, the Oneiromancer says, both characters need each other to survive. If one dies, both die, "just as if you were killed by a monster in the wild," the Oneiromancer cautions.

To make the potion, you fill an empty Dream vial with water, a ground Astral rune, and a Goutweed.
