I know there is probable a topic for this question already, but I don't know where. How do you create a spell, where do you put them.

You might try this topic first, and then see if you have more specific questions to ask :) It's got a section on scrolls if you scroll down a little bit, which will give you a basic introduction.

Thanks for the help, have a good day.

You can create a spell Here To Create certain level spells, you Need AP, which is obtained from reading books

More info On Scrolls/spells/AP can be found here A Guide which is specifically about spells
