Duration: Special
Casting Time: 5
Area of Effect: Special
Saving Throw: Special

The shadow magic spell enables the wizard to tap energy from the Demiplane of Shadow to cast a quasi-real wizard evocation spell of 3rd level or less. For example, this spell can be magic missile, fireball, lightning bolt, or so on, and has normal effects upon creatures in the area of effect if they fail their saving throws vs. spell. Thus, a creature failing to save against a shadow magic fireball must roll another saving throw. If the latter roll is successful, the creature suffers half the normal fireball damage; if the roll is not successful, the creature suffers full normal fireball damage. If the first saving throw was successful, the shadow magic nature is detected and only 20% of the rolled damage is received (rounding down below fractions below 0.4 and rounding up fractions of 0.4 and above).
