Demi-shadow 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 demi-shadow 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 demi-magic cloudkill slays creatures with fewer than 2 Hit Dice and inflicts 1d2 points of damage per round.
