Scholiast (Sp)

At 3rd level, an Arclord of Nex can access the wizard school powers of another school of magic. He chooses a single arcane school spell-like ability that has a number of uses per day equal to 3 + his Intelligence modifier. Henceforth, he may use that ability (with a wizard level equal to his caster level) by expending two uses of his hand of the apprentice ability. A specialist wizard needs to expend two uses of his equivalent ability if using scholiast for hand of the apprentice, but still has to expend one additional daily use (for a total of three) to use it for a power of a different school. At 6th level and again at 9th level, an Arclord of Nex can choose an additional arcane school spell-like ability to use with this ability.
