CS' Rage of Demons
Stool is a myconid sprout captured by Sarith Kzekarit. Stool is lonely and frightened, wanting only to return to its home in Neverlight Grove. If befriended by the characters, Stool gladly offers to guide them to its home, promising them sanctuary with its folk.
Stool uses rapport spores to establish telepathic communication with other creatures, and it does so to communicate with characters who are kind and friendly toward it. The myconid will also help establish communication with Underdark denizens with whom the characters don’t share a language.
