Alright, it now also gives a +2 bonus to the ability score damage, which is pretty good for a 3rd level spell I think.
Alright. Limited to 1/2 CL, max 10.I would worry about punishing curse doing extreme amounts of ability damage. The spell could basically turn into a save or die, which is impressive for a 2nd level spell. I would limit it somehow, maybe to a maximum of half your caster level.
Fair enough. But the increased damage alone isn't enough...at that point I might as well just cast maximized moon bolt instead. So what would you suggest?Moon bolt is also much too powerful to not allow a save. Otherwise your DM might start throwing spell reflecting monsters at you.
Added the requested Alfek's curse of retribution, and my personal favorite, the almighty Alfek's touch of complete decay.
