Illusionists use magic to weave confounding images, figments, and phantoms to baffle and vex their foes.
Extended Illusions (Su)
Add an additional one half your wizard level when determining the duration of illusion spells. This extra duration is not doubled by Extend Spell Metamagic. At 20th level any non-hostile illusion spells have a duration of 24 hours.
Blinding Ray (Sp)
As a standard action you can fire a shimmering ray at any foe within 30 feet as a ranged touch attack. The ray causes creatures to be blinded for 1 round. Creatures with more Hit Dice than your wizard level are dazzled for 1 round instead. You can use this ability a number of times per day equal to 3 + your Intelligence modifier.
Invisibility Field (Sp)
At 8th level, you can make yourself Invisible as a swift action for a number of rounds per day equal to your wizard level. These rounds do not need to be consecutive. This otherwise functions as greater invisibility.
