Granny Wax

Normally found in a small glass jar containing 1d3 doses, this foul-smelling, greasy yellow substance is made by hags in accordance with an age-old secret recipe. You can use an action to rub one dose of the wax onto an ordinary broom or wooden stick and transform it into a broom of flying for 1 hour.
