Ideas for Natha's Curse

In my game, the player's group was cursed by a Natha's Ordinate (another PC) in Full Moon day in a very dramatic situation. Their sin was more or less "irreflexive violence". Her words something like that: "May JagaNatha, Godess of Revenge, pursue you wherever you go and may she punish all of you for your boldness".

All players suggested me no dice rolls. They considered that, in this particular context (the curse was specially interesting in that situation) no self-respecting Ordinate would fail.

Now I'm not sure about the curse's content. Any ideas about Natha's punishments?
