Hey guys! I am just getting into GMing Warhammer 3rd Edition. My question is, what should the next supplement I buy? I can see the advantage of all three. More creatures are always good for my players to fight against, but this IS the Warhammer world and magic and it's relation to Chaos is vital. But just as vital are the various religions of the Empire and their influence on everyday life. Everyone has been touched by one of the Cults in some way or another, and more info on that is always good.
The only difference between them all is price - Creature Vault is $22, while Winds of Magic and Signs of Faith will be $35 each.
I (obviously) already have the Core Set, and the GM Toolkit and the Adventurer's Toolkit are en route.
