Spell Guidlines
Magic can mean a lot of things. There's far too many styles and such of magic to put in a box so there are many spells and 'schools'. Some magic requires incarnations, while others is activated by thought. While some may be more powerful then others, most have their own strengths and weaknesses.
1. If making an original spell list, try to keep things reasonbale. There should be low level as well high level ones. Not every spell can be all powerful.
2. The spell process is much like the character approval process. If the managers see something wrong, they'll let you know.
