The character taps energy from the Plane of Shadow to cast a quasi-real, illusory version of a wizard or sorcerer evocation of 5th level or lower. (For a spell with more than one level, use the best one applicable to the character.) If recognized as a shadow evocation, a damaging spell deals only two-fifths (40%) of normal damage, with a minimum of 2 points per die of damage.. Regardless of the result of the save to disbelieve, affected creatures are also allowed any save the spell being simulated allows, but set the save DC according to shadow magic's level (6th) rather than the spell's normal level. Nondamaging effects are only 40% likely to work when the greater shadow evocation is recognized as mostly illusory (roll separately for each effect and each creature who recognizes the evocation as shadowy).
