Yes, there is a curse, it might just be called something else. At the beginning of the game, you get an amulet (or something like it) with a curse spell as a reward for a mission. If you cast it on, for example, a boar, its damage and health decrease by a percentage (and the boar also gets smaller).
It's a great amulet, you can almost complete the entire game with it... plus, the amulet affects three enemies at once.
