Jhulae said:Bucklers state that your hand is free, because you can use it to make attacks with held weapons and such. There's no reason to restrict spellcasting. I can see not allowing the cleric (or paladin or ranger, or arcane casters who wear bucklers) to gain the AC bonus for the round, but absolutely no reason can be made to disallow casting with a buckler, except as an arbitrary descision.
Except that in no way the buckler states that your hand is free. It just specifies that you can use a bow or crossbow at no penalty, or that you can use an off-hand weapon (or use the hand for a two-handed weapon) with -1 to attacks, but your hand is not free. It is NOT an exception for spellcasting. There is absolutely no reason to alllow casting with a buckler's hand except as an arbitrary decision.
