From publisher blurb:
Double double toil and trouble, cauldron's brew and potion's bubble. A dash of newt's tail and a big of dragon's feather and your newest concoction will be completed. What's it do? Well. You tell us, you're The Witch.
The Witch is a playbook for the Dungeon World roleplaying game. She is a potion brewing spellcaster with dark and forbidden magicks at her command. Her abilities differ from her wizard companion considerably - while he has his little list of spells, the witch has her hexes, her potions, and her broomstick. You are The Witch, and your powers are eldritch and eternal.
