For Deities domain selection, would a prestige domain (ie, Exorcism from Defenders of the Faith) take one of their limited domain spots? Or just added as a flavor?
[ Yes I do realize I can hand-wave it either way , just wanted to know if there was precedent either way ]
Well, I don't think there's a precedent per se, but the prestige domains were designed to work with the gods in the PH who already had all their domains assigned, so I'd say go with it.
