Given that the Archmage PrC has to sacrifice spell slots to obtain those cool abilities, is there an reason why a Specialist mage cannot sacrifice his bonus spell slots? In other words, can my Diviner sacrifice his divination-only spell slots to gain these abilities?
I can find nothing in the rules that says otherwise, since the Archmage PrC simply states that you must sacrifice a spell slot, and doesn't specify what kind of spell slot must be sacrificed.
