I just learned that sims can duel for 5 different outcomes. My sims dueled in TS3 mainly for entertainment value, seeing all the effects. I will be having my sims duel a lot more in Realm of Magic...
Here's a nice little detail they added with dueling. I'm really into dueling right so much so that my sim has 2 curses and almost died from overload once. https://i.imgur.com/ELiZZrW.jpg
