In one of my games, all of my players and I went to level up a set of warlocks (All different subclasses) and spells from a book I do not own (Midgaurd Hero's handbook) appear in the lists as options but are not in my (Or any of my players) compendium. It's caused a good deal of confusion because there also seem to be spells missing from their lists that they should have available due to their subclasses (Such as telekinesis). Help would be appreciated, is this expected as a sort of advertisement (And is there any way to remove them if so?) or is this some sort of error? Is anybody else experiencing this?
