The caster level of a cast spell is a measure of the power of that particular casting. For spells cast by a character, this is the character's level in the class used to cast the spell. For spells cast from items, the caster level is given in parentheses after the relevant item property. Epic spells cast from items are an exception in that their caster level is not given in parentheses. The caster level for most default epic spell item properties is 25, with the exceptions being epic warding and hellball, for which the caster level is 30. Sequencers (and other items that allow the dynamic setting of spells to be cast) are another exception, as they use "cheat casting" which uses a caster level of 2×innate level − 1, with a minimum of 10.
