Hetty

Hetty is a witch located in the southeast house in Rimmington and plays the main role in the Witch's Potion quest.

Upon asking her for a quest, she offers to teach the player "dark arts" in exchange for ingredients to the brew. After bringing her burntmeat, an eye of newt, an onion, and a rat's tail, she puts them in the nearby cauldron and offers the player a drink. Upon doing so, the quest is completed and the player earns some Magic experience.
