Shadow Evocation (Lightning Bolt)

You tap energy from the Plane of Shadow to cast a quasi-real, illusory version of a lightning bolt spell. Lightning Bolt: You release a powerful stroke of electrical energy that deals 1d6 points of electricity damage per caster level (maximum 10d6) to each creature within its area. If an affected creature succeeds at a Will save to disbelieve, it takes only 20% damage from the attack.
