Associated School: Illusion.
Replacement Powers: The following school powers replace the blinding ray and invisibility field powers of the illusion school.
Binding Darkness (Sp): As a standard action, you cast a weave of shadows at any foe within 30 feet as a ranged touch attack. The shadows entangle your foe for 1 round plus 1 additional round for every five wizard levels you possess. In conditions of bright light, this duration is halved (minimum 1 round). A creature entangled by your shadows has concealment from those without darkvision or the ability to see in darkness, and other creatures likewise have concealment relative to it. You can use this ability a number of times per day equal to 3 + your Intelligence modifier.
Shadow Step (Sp): At 8th level, you can use this ability to walk through the Shadow Plane and reappear as a standard action. You can travel up to 30 feet per wizard level per day in this fashion, either in a single round or broken up across multiple shadow steps. This movement must be used in 5-foot increments and does not provoke an attack of opportunity. Travel through the Shadow Plane is imprecise; when you arrive, you re-enter 1 square off target, as per the rules for thrown splash weapons. If this would place you in an occupied square, you instead arrive in the nearest safe location. When you arrive, you are cloaked in shadow and gain concealment as the blur spell for 1 round. You may bring other willing creatures with you, but you must expend an equal amount of distance for each additional creature brought with you. They likewise re-enter off target (roll location for each creature) and are cloaked in shadow for 1 round.
