Extend Illusion: Any illusion spell you cast with a duration of “concentration” lasts a number of additional rounds equal to 1/2 your wizard level after you stop maintaining concentration (minimum +1 round). At 20th level, you can make one illusion spell with a duration of “concentration” become permanent. You can have no more than one illusion made permanent in this way at one time. If you designate another illusion as permanent, the previous permanent illusion ends.
Face in the Crowd(Su): At 1st level as a standard action, you can cause yourself to appear so normal, mundane, and unexceptional that you blend in to your surroundings. All creatures within 30 feet treat you as if you belonged there, effectively ignoring you. Creatures outside of this area may notice that you appear out of place, but as soon as they approach within 30 feet they are affected by the magic and no longer think something is amiss. If you interact with an affected creature in any way, it gains a Will save (DC 10 + 1/2 your wizard level + your Intelligence modifier) to disbelieve the illusion and notice you. The effect lasts for a number of minutes equal to your wizard level, or until the illusion is dispelled. The minutes do not need to be consecutive, but must be used in 1-minute increments. This is a mind-affecting phantasm effect.
This ability does not turn you invisible and opponents are not considered flat-footed. It does not allow you to disguise yourself as a specific individual, type of person, or member of another race, so you cannot blend into a group of uniformed guards or appear as a member of an individual’s family, and a human cannot blend into a group of gnolls. You can blend in with any group made up of different types of people, such as a crowd of courtiers in a king’s throne room, and you can disguise yourself (either through magic or more mundane means) to appear as a specific type of person or another race (such as a uniformed guard or a gnoll) before using this ability.
Master of the Veil(Su): At 8th level, you can create an illusion that hides the appearance of yourself and any number of allies within 30 feet for 1 round per wizard level. This ability otherwise functions like the spell veil. The rounds do not need to be consecutive.
