Not strong of body, and questionable of mind, she has a kind heart and one special talent. She is not a healer of wounds, or even of people, she heals the souls of creatures. She feels sympathy for even the most hideous and terrible of creatures, and when her tears for them fall upon them, their hearts are moved and their evil ways ended(for a little while at least).
A slow, stupid creature that crawls onto people and latches onto them, often on feet, hands, and other extremities, numbing down the area and slowly feeding on it. It's easy to avoid while awake, but nearly impossible to remove once attached. Many an adventurer has been forced to hack off an arm or leg after waking with a Stoneleech wrapped around it. Sleep with one eye open! (This idea came from "Wizard's Rule")
