Shadow Evocation (Ki Shout)

You tap energy from the Plane of Shadow to cast a quasi-real, illusory version of a ki shout spell. With a guttural bark, you unleash a sudden blast of sonic energy that strikes your opponent. The target takes 1d6 points of sonic damage per level (maximum 20d6) and is stunned for 1 round. A successful Fortitude save reduces the damage by half and negates the stun. If an affected creature succeeds at a Will save to disbelieve, it takes only 60% damage from the attack.
