Developing Spells
This is a list of guidelines for determining the composition and DC of spells based upon a number of factors. It is, however, not hard and fast rules - these are suggestions. Ultimately it is a tool for the GM, who decides the DC based upon whatever factors they see reasonable.

DC
Range
The default range of any spell is 60 feet. The DC in general may be reduced by around 2 if it is reduced to 30 feet, and by around 4 if it is reduced to 5 feet or touch.
To increase the range of a spell beyond 60 feet it must be cast as a mixed spell with the Space Discipline.
Duration
Saves
Determining if a spell should allow a save, and what save should be used, is tricky.
Generally only spells that fall under the Mind discipline have will saves, and most of them have them automatically. The hard and fast rule is: if it incorporates Mind, a will save is allowed.
