Start broom creation by making of Magical Altar.
Create cool-looking witch apparel by combining leather armor with Butterfly scales. There is a chance of them dropping from a witch, or you can trade them with Ada.
Only two parts are needed to craft a magical broomstick: a grip and a tip. Use the different wood times to customize how it looks. After you've got your wooden broom, you need to fill it with magic. Put the broom on the altar and use Butterfly scales on it.
After you've decided on the design, use a broomstick of the same type you used initially to take it from the altar. All that's left is to hop in on your newly created Magical broomstick and fly high up to the skies.
