I notice that Ao is not listed among the deities in the "Faiths of Faerun" section of the forums.

Does this mean that if I create a cleric of Ao that he will not be able to use spells, which is precisely how it should be?

I am not really knowledgeable about this at all, but I am pretty sure Ao only grants spells to other deities, not followers. You won't recieve spells in game as a level 2 cleric.

edit: confusing wording!

Ao does not grant spells to mortals.

Your cleric of Ao will receive no spells or relevant abilities.
