I don't know that I'd go mass-curse-no-save - in one campaign I had, I ran mind-control as a disease: specifically, people were handing out bits of paper that effectively gave you a minus to your save versus mind control, and the mind control mostly consisted of you wanting to hand out the bits of paper to other people.

So what if you model it on a disease instead of all-must-come-under-my-control-now? You could have it be a once a day to one person in a village, and if it spreads, it should quickly take over most of the population within earshot...

You could even have it be two spells.

The first is the Curse of Prohibition

The second is Contagious Curse
