Allow saves on spells without damage requirement

Currently the spells that demand a save, have to be attacks, and must have damage associated with them. Enable the saves to be performed even if it is not an attack. Or alternatively, allow for 0% damage for the spell, so that it doesn’t do damage when you cast it. Right now, even if you set 0% damage on both save options and save, it sets it to default for 50% and 100%
