Demishadow Magic
This spell is similar to the 5th-level Shadow Magic spell, but this spell enables the casting of partially real 4th- and 5th level Evocations (cone of cold, wall of fire, wall of ice, cloudkill, etc.). If recognized as demishadow magic (if a saving throw vs. spell is successful), damaging spells inflict only 40% of normal damage, with a minimum of 2 points per die of damage. A demishadow magic Cloudkill slays creatures with fewer than 2 Hit Dice and inflicts d2 points of damage per round.
