Essentially, mages are just a special class of people with 'spells' or 'talents' instead of or in addition to 'powers'. Each such spell, talent, or magical ability must be presented with all the thoroughness of any power. Describe what it takes to utilize the spell and what the effects are. Give such information as range, power levels, durations, limitations, areas of affect, cost of casting the spell, and even information on spell backlash should it misfire.
