What stuff can a wizard or witch cast?

Answer 1

Just to make things a bit clearer here.

Witch is a non-gender specific word usually associated with practitioners of one of a great number of nature based spiritual paths commonly found under the umbrella term "paganism".

Wizard is a non-gender specific word usually associated with those who study the Craft but do not necessarily follow a spiritual path.

As for the "stuff they cast. Like all humans they can cast a glance, cast a line, cast a play, cast aspersions, cast a broken limb, cast away, or cast adrift. They can also cast spells, but that is just a very small part of what they do.
