Removing Spells
 

In our campaign we have a lot of spells we have banned from use.

Is there a way to remove spells from the selection? Like for example creating a new rule in the editor to restrict spells?

You want to look at the *Hidden or *Preclude tabs in the editor. *Hidden will always hide the spells. *Preclude will let you only hide the spells when a specific Source is turned on.
