The Casting Roll is performed when a character casts a spell that has an offensive component — a spell that causes either damage or effects on one or more targets. The Casting Roll is also necessary if the target of a beneficial spell doesn't wish to receive the effects. Attack Spells will typically give you a bonus to this roll per level of Intensity.

This roll is opposed by a save, which is a skill listed in the individual spell. Defending characters may add to this save either Magic Defense or their ranks in the spell cast on them, whichever is higher.
