Shadow Evocation (Fireball)

You tap energy from the Plane of Shadow to cast a quasi-real, illusory version of a fireball spell. Fireball: This spell generates a searing explosion of flame that detonates with a low roar and deals 1d6 points of fire damage per caster level (maximum 10d6) to every creature within the area. A successful Reflex save halves this damage. If an affected creature succeeds at a Will save to disbelieve, it takes only 20% damage from the attack.
