Arbiter spirits are the Blue Sentinels that invade other worlds to kill an invader. You're probably thinking of Blue Phantoms. (I'm fairly certain that this is the case, please correct me if I'm wrong.)

Either way, the wording makes it seem like they only count Black Phantoms, or BoB invaders, so no, Arbiters don't count.

On an unrelated note: Doesn't it affect Hexes as well? The page only mentions the original three spell types.
