An arcane knight of the illusion school gains the following powers.
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 arcane knight 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 11th level, you can make yourself invisible as a swift action for a number of rounds per day equal to your arcane knight level. These rounds do not need to be consecutive. This otherwise functions as greater invisibility.
