Perhaps a good prize would be some sort of item for each winner that is related to their god. Like, for Brigid followers, light armour that gives high physical resistance (since they can't use weapons) and some speed. Or for Govannon followers, powerful armour that boosts slow and confuse resistance. For Ogma followers, a club that strongly poisons and boosts magic resistance. Et cetera.

Names could be things like ..

Leather armour of Brigid
Heavy platemail of Govannon
Orcish club of Ogma
