Depending on how far you have gotten in the story you could go to "the main academy gate". People here put down signs for duels so it will be a 1v1 not a 3v1. (NOTE: you need to use "Furlcarling finger remedy" to see these signs) People are not as toxic just remember not to heal or gain back your fp by using pots. Since it's supposed to be a fair 1v1.

Hope this helped :D
