Start: Talk to Hetty the witch in Rimmington.
Requirements: None!
What You Need: An Eye of Newt, a Rat's Tail, an onion, and a piece of burnt meat.

Getting Started

Firstly, visit Hetty the witch in Rimmington and tell her that you're looking for a quest. She says that she may have something for you to do, and she asks you if you want to get better at the "Dark Arts" (a.k.a. Magic). Say yes, and she tells you that she needs a potion consisting of an Eye of Newt, a Rat's Tail, an onion, and a burnt piece of meat.

Making the Potion

All of the ingredients needed for Hetty's potion can be found near Rimmington. You can buy an Eye of Newt from the Magic Emporium in Port Sarim for 3gp. Fresh onions grow in the garden just north of the town. You can find some Rats just south-east of town, which you can kill for meat to later burn on a stove. Kill a small level 1 Rat and pick up their Rat's Tail, another needed ingredient.

After obtaining all of the required ingredients, go back to Hetty and give her all of the items. She mixes a potion in her Cauldron, which you can drink from to complete the quest.
