This is old info from before the last 2 patches, but I played this aspiration still very recently and I noticed that wins only count toward the aspiration if my sim initiates the duel herself. If she gets a text from another spellcaster asking for a duel, the win will be completely ignored by the aspiration and agreeing to meet up with these sims is a complete waste of time. I will test it with the current version of the game soon, if I remember to. But in the meantime maybe this will be helpful.
I have returned to say that things work as expected on my end. I invited over a spellcaster, asked her to duel, and fought her in the middle of my driveway and the aspiration was happy with that. I'm in the newest version of the game.
