My new sim who've just become a spellcaster got the Curse of Unwarranted Hostility yesterday while trying to cook up some plentiful needs potions. She was attacked by a random stranger, but she kicked his butt twice. Ha! I frantically had her experimenting, hoping she would discover the decursify potion or whatever it's called, but eventually I gave up and loaded the last save. Luckily it wasn't too long before the incident. I'll be sure to always save before brewing stuff from now on. xD The other curses don't sound fun either.
