I don't know what 3.5e says, but in 3.0 one spell does not stack with itself, even if it gives an unnamed bonus/penalty. PHB page 153: "Spells that give bonuses or penalties to attack rolls, damage rolls, saving throws, and other attributes usually do not stack with themselves." Bonus names only come into it when you're dealing with bonuses from different sources.Al said:Don't have 3.5e, so I'm just going on the quotations, but isn't the penalty type unnamed? In which case, should it not stack with itself? Or is it an 'enhancement penalty' (as per RoE currently is).
