K.O.M.E.T. Agent Prestige Class

Okay, the K.O.M.E.T. agents I've written in "Balls" are a mixed bag, coming from several different disciplines. If there's anything linking them, its some degree of detective skills which are not otherwise available to typical wizard types. When writing, I didn't want to create seven people who all did the same thing. Hell, the dwarf and the invisible magic ninja never even casted any spells, so magic is probably not a requirement.
The KOMET agent PrC is a simple 5 level PrC that fits loosely over a prevailing character class.
1st level: +1 effective level for arcane stuff (spells, spell-like abilities, etc), +2 Knowledge: Area (Kasteban), Perception and Sense Motive and those become class skills no matter what class you advance in, legal powers throughout Kasteban
2nd level: +1 effective arcane level
WHY ADVANCE IN THIS PrC? Better skill point pool and skill selection?
Maybe at higher levels there are abilities that come into play as the character gets in tune with Kasteban?
I can definitely see some sort of spell resistance, considering that they specifically fight arcane threats.
Sense criminal intent?
