Note: This calculator is intended for basic spell design. Some features, such as multiple effects, alternate areas of effect, multiple or extended applications of optional modifiers (i.e. community), or any customized or game-master-mediated elements, are not supported by this calculator. Furthermore, constraints imposed by the rules are not checked. All inputs except Other Factors should be positive numbers. (Other Factors may be either positive or negative.)
Note: When not used with an order of magnitude, the values 4 and 6 are actually 3.5 and 5.
Reminder: Miracles have a minimum casting time of 1.5 seconds, cannot have charges except as wards, and cannot create a ward that can be bypassed by a skill. Miracles have a minimum difficulty of 5. Spells have a minimum difficulty of 10 unless the conditions for cantrips are met.
