Shadow Evocation (Sirocco)

You tap energy from the Plane of Shadow to cast a quasi-real, illusory version of a sirocco spell. A blast of furnace-hot wind blasts downward, inflicting 4d6 fire damage + 1 point per caster level to all creatures in the area and knocking them prone. A successful Fortitude save halves the fire damage and negates being knocked prone. If an affected creature succeeds at a Will save to disbelieve, it takes only 60% damage from the attack. Any creature that takes damage from a sirocco becomes fatigued (or exhausted, if already fatigued, such as from a previous round of exposure to a sirocco spell). Creatures with the water subtype take a –4 penalty on all saving throws against this spell and take double normal damage.
