Also no healing spell requires an attack roll. In 3rd edition there were some spells that were Save (Harmless) that you could choose to try to make a saving throw to resist them. Once I was playing an Athar who would resist any spell granted by a deity but it was me rolling the dice not the caster.

I've seen many a game have a "absolute success/failure" rule.

Makes for good stories usually.
