Diviners are masters of remote viewing, prophecies, and using magic to explore the world.
You can always act in the surprise round even if you fail to make a Perception roll to notice a foe, but you are still considered flat-footed until you take an action. In addition, you receive a bonus on initiative checks equal to 1/2 your wizard level (minimum +1). At 20th level, anytime you roll initiative, assume the roll resulted in a natural 20.
Diviner's Fortune (Sp)
When you activate this school power, you can touch any creature as a standard action to give it an insight bonus on all of its attack rolls, skill checks, ability checks, and saving throws equal to 1/2 your wizard level (minimum +1) for 1 round. You can use this ability a number of times per day equal to 3 + your Intelligence modifier.
Scrying Adept (Su)
At 8th level, you are always aware when you are being observed via magic, as if you had a permanent detect scrying. In addition, whenever you scry on a subject, treat the subject as one step more familiar to you. Very familiar subjects get a –10 penalty on their save to avoid your scrying attempts.
